It has reasonable security consideration, although the words, "The lowest NETCONF layer is the secure transport layer" seems a bit awkward.

Please note that I do NOT follow the ROLL WG. The draft has made a huge step forward in readability compared to last year. The extended terminology section helps a lot to understand the document. All the figures/tables have been cleaned up considerably and they all use the "Figure" term instead a mixture of figures and tables. Abbreviations are also used more consistently, which both helps with the table cleanup and the readability in general. I think draft 42 resolves the issues I had in my earlier review.

Since the draft progressed till v21 i assume the working group found an agreement on the usefulness of the idea. Please see my previous comment: "My concern, which is something the working group probably already discussed, is about the complexity and usefulness of the idea. The goal of draft is: "The core of this solution is the ability for an operator to specify on a per route reflector basis or per peer/update group basis or per peer basis the virtual IGP location placement of the route reflector. This enables having a given group of clients receive routes with optimal distance to the next hops from the position of the configured virtual IGP location. This also provides for freedom of route reflector location and allows transient or permanent migration of such network control plane function to optimal location.” But I understand that there is a number of workarounds and that different paths are already used for redundancy reasons, hence my questions is: is it worth defining a new solution? Is the usage of the actual mechanisms so disoptimized to require these changes? How many possible paths are there between the client and the AS border node?" I see that appendix A has been added with alternative solutions, very good. I only found minor comment and nits. - Astract: "to choose the best path for their clients standpoint" i guess this should be "From their clients standpoint" - Abstract: "multiple type - multiple types" - Section 3: there are some issues with bullet items - Section 3: "The first change is related to the IGP cost to the BGP Next Hop, which is done in the step e) in the BGP decision process" where is step e) defined? maybe a missing reference? ...further reading the document i find a description of step e) in section 3.1. Maybe just saying "as described in section 3.1 " would be enugh. - Section 3.1. Since step e) is modified probably the draft should update RFC 4271? Overall i like the way that the abstract and the introduction have been updated, with the former introducing the solution and the latter well explaining the problem to be solved.

Although these comments are pri= marily for the use of the Routing ADs, it would be helpful if you could con= sider them along with any other IETF Last Call comments that you receive, a= nd strive to resolve them through discussion or by updating the draft.

Reviewer: Nicolai Leymann =

Review Date: 12/02/2020

IETF LC End Date:

Intended Status: Proposed Stand= ard

 

Summary:

  • This document is basically ready for publication= , but has nits that should be considered prior to publication.

 

Comments:

Th= e draft describes a mechanism for associating policies to a group of LSPs. =  This is done by via a small extension to PCEP.  The draft is in = good shape and describes the extensions in detail. It’s written in a clear language and there is good support for the d= raft. One implementation is mentioned in the document ensuring that there a= re real deployments available.

 

Major Issues:=

  • "No major issues found."

Minor Issues:=

  • “No minor issues found.”<= /span>

Nits:

  • The name in the head line of each page could be = more descriptive: „Internet-Draft ASSOC-POLICY October 2020“ E.g. instead of „ASSOC-POLICY“ use „PCEP extension for as= sociating Policies“ or something similar.
  • Error values for „TBD3“ and „TBD4&#= 8220; are not defined.
  • Number of authors should = be checked (currently six authors are listed, see RFC7322).

The Routing Directorate seeks to review all routing or routing-related drafts as they pass through IETF last call and IESG review, and sometimes on special request. The purpose of the review is to provide assistance to the Routing ADs. For more information about the Routing Directorate, please see http://trac.tools.ietf.org/area/rtg/trac/wiki/RtgDir Although these comments are primarily for the use of the Routing ADs, it would be helpful if you could consider them along with any other IETF Last Call comments that you receive, and strive to resolve them through discussion or by updating the draft. Document: draft-ietf-spring-sr-yang-28 Reviewer: Tal Mizrahi Review Date: 08-Dec-2020 Intended Status: Standards Track Summary: I have some minor concerns about this document that I think should be resolved before publication. Comments: The document defines a YANG data model for MPLS segment routing. The document is in good shape, and I believe it is almost ready for publication. My comments are mainly about the need for a clear definition of the scope of the document. While these comments do not require major changes in the document, a bit of rephrasing and clarifying text will go a long way here. Issues: - The document is focused on SR-MPLS, while RFC8402 discusses both SR-MPLS and SRv6. I am sure there is a good reason for this, but it is important to point out at the very beginning of the document that it does not cover SRv6 and preferably also the reason for this. - It is important to clarify the scope of the YANG models in the introduction: do they refer only to SR routers, or also to SR ingress/egress nodes? - The Common Types module is mentioned for the first time in Section 8. It would be appropriate to mention it and describe its purpose in Section 3. - In the following text it would be more accurate to replace: "with Segment Routing (SR)." ==> "with MPLS Segment Routing (SR)." "This augments routing data model (RFC 8349) with Segment Routing (SR)."; From nobody Tue Dec 8 04:22:01 2020 Return-Path: X-Original-To: rtg-dir@ietfa.amsl.com Delivered-To: rtg-dir@ietfa.amsl.com

Hel= lo,

I have been selected as the Routing Directorate reviewer for this
draft. The Routing Directorate seeks to review all routing or
routing-related drafts as they pass through IETF last call and IESG
review, and sometimes on special request. The purpose of the review is
to provide assistance to the Routing ADs. For more information about
the Routing Directorate, please see
http://trac.tools.ietf.org/area/rtg/trac/wiki/Rt= gDir

Although these comments are primarily for the use of the Routing ADs,
it would be helpful if you could consider them along with any other
IETF Last Call comments that you receive, and strive to resolve them
through discussion or by updating the draft.

Document: draft-ietf-spring-sr-yang-28
Reviewer: Tal Mizrahi
Review Date: 08-Dec-2020
Intended Status: Standards Track


Summary:
I have some minor concerns about this document that I think should be
resolved before publication.


Comments:
The document defines a YANG data model for MPLS segment routing. The
document is in good shape, and I believe it is almost ready for
publication.

My comments are mainly about the need for a clear definition of the
scope of the document. While these comments do not require major
changes in the document, a bit of rephrasing and clarifying text will
go a long way here.


Issues:
- The document is focused on SR-MPLS, while RFC8402 discusses both
SR-MPLS and SRv6. I am sure there is a good reason for this, but it is
important to point out at the very beginning of the document that it
does not cover SRv6 and preferably also the reason for this.
=C2=A0
=C2=A0[Yingzhen]: yes, this document focuses on the= SR-MPLS data plane. However there is ietf-segment-routing.yang module defi= ned as the generic frame, which is meant to be augmented by different data = planes, including both SR-MPLS and SRv6. This was the consensus between the= authors of this draft and authors of SRv6 YANG model. If you think the abs= tract and introduction is not clear, please let us know.=C2=A0
= =C2=A0=C2=A0
- It is important to clarify the scope of the YANG models in the
introduction: do they refer only to SR routers, or also to SR
ingress/egress nodes?

[Yingzhen]: =C2= =A0for ingress/egress nodes, do you mean SR policy? which is defined in a s= eparate draft: https://tools.ietf.org/html/draft-raza-spring-sr-policy-yan= g-03=C2=A0
=C2=A0
- The Common Types module is mentioned for the first time in Section
8. It would be appropriate to mention it and describe its purpose in
Section 3.

[Yingzhen]: Good suggestion.= I added a small paragraph for the common yang module.
=C2=A0
- In the following text it would be more accurate to replace: "with Segment Routing (SR)." =3D=3D> "with MPLS Segment Routing (SR)= ."

=C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0"This augments routing data model (R= FC 8349)
=C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 with Segment Routing (SR).";

[Yingzhen]: fixed.

Reviewer: Nicolai Leymann

Review Date: 12/02/2020

IETF LC End Date:

Intended Status: Proposed Standard

 

Summary:

  • This document is = basically ready for publication, but has nits that should be considered pri= or to publication.

 

Comments:

The draft describes a m= echanism for associating policies to a group of LSPs.  This is done by= via a small extension to PCEP.  The draft is in good shape and descri= bes the extensions in detail. It’s written in a clear language and there is good support for the draft. One implementati= on is mentioned in the document ensuring that there are real deployments av= ailable.

 

Major Issues:

  • "No major is= sues found."

Minor Issues:

  • “No minor i= ssues found.”

Nits:

  • The name in the h= ead line of each page could be more descriptive: „Internet-Draft ASSO= C-POLICY October 2020“
    E.g. instead of „ASSOC-POLICY“ use „PCEP extension for as= sociating Policies“ or something similar.

 

[Cheng]I changed to "PCEP Extensions for Policy Associat= ion".

 

  • Error values for = „TBD3“ and „TBD4“ are not defined.

 

[Cheng] While the rest of the codepoints are early allocated = by IANA, these are not. They need to be still allocated by IANA and noted i= n section 8.3 [ https://tools.ietf.org/html/draft-ietf-pce-as= sociation-policy-13#section-8.3 ]

 

  • Number of authors= should be checked (currently six authors are listed, see RFC7322).

 

[Cheng]This has been captured in the shepherd report, we made= a request to allow one extra author to accommodate the various authors/aff= iliations who were involved in this and the earlier drafts on policy in PCEP.

 

The revision 14 has been posted, please check it. https://tools.ietf.org/html/draft-ietf-pce-as= sociation-policy-14

List-Help: List-Subscribe: , X-List-Received-Date: Thu, 17 Dec 2020 16:08:43 -0000 Hello, I have been selected as the Routing Directorate reviewer for this draft. The Routing Directorate seeks to review all routing or routing-related drafts as they pass through IETF last call and IESG review, and sometimes on special request. The purpose of the review is to provide assistance to the Routing ADs. For more information about the Routing Directorate, please see ​http://trac.tools.ietf.org/area/rtg/trac/wiki/RtgDir Although these comments are primarily for the use of the Routing ADs, it would be helpful if you could consider them along with any other IETF Last Call comments that you receive, and strive to resolve them through discussion or by updating the draft. Document: draft-ietf-roll-unaware-leaves-23 Reviewer: Julien Meuric Review Date: 2020-12-17 IETF LC End Date: 2020-12-09 Intended Status: Standards Track *Summary:* I have some minor concerns about this document that I think should be resolved before publication. *Comments:* I am not an LLN expert, but I find the I-D convenient to read thanks to the appropriate (but numerous) references. I just feel that a few sections deserve some clarification to improve readability and that flag number selection doesn't really follow the expected process. *Major Issues:* No major issues found. *Minor Issues:* - Sorry if ask questions on implicit contexts that are obvious to LLN people, but I am confused in section 3 with that "6LR that acts as a border Router for external routes": does it advertise towards the RPL domain? Does it talk to a peer 6LR that is also a RPL Router? Is that particular router necessarily the RPL Root? - The text in section 6.2, as well as figures 3 and 4, use the F and P flags as if the bit numbers were defined, though their number is only "suggested" in the IANA section. If no early allocation process happened, it is inappropriate to assume the to-be-allocated bit number in the body of the document. - Section 6.3 reduces an 8-bit field to a 6 bit value. It would be worth mentioning that it sounds reasonable because the associated registry relies on standards action for registration and only values up to 10 are currently allocated. Furthermore, is there an update of that 6-bit space split to map the previous ranges? If the answer lies in the IANA section, then a few words would be welcome in section 6. *Nits:* ------ Overall --- - RPL-[An]aware, RAL and RUL are preceded most of the times by "a" [OK if pronounced "riple", "ral", "rul"], but sometimes by "an" ["are pi..."]: please pick one and be consistent. - Any reason why "Host", "Hop" and "Router" are often written with a capital H/R? - RFC 2119 keywords SHOULD be used more often for an IETF standard track, it sometimes feels that the text is written to circumvent them. E.g., section 4.2.1 uses a wording based on "requires... if and only if..."; section 4.3 describes a behavior without any normative keyword; section 5.1 says "needs to", "is expected not to", "is suggested to"; etc. ------ Section 1. --- - The phrase "terminate packets" feels odd: is "terminate paths" intended? - s/expectations/requirements/ - The term "change" is used several times in the section summary though it is a bit loose: depending on the situation, "modify" or "extend" would be more specific (the former may impact existing implementations, the latter does not). -  OLD       Section 8 presents the changes made to [RFC6775] and [RFC8505];       The range of the ND status codes is reduced down to 64 values, and       the remaining bits in the original status field are now reserved.   NEW       Section 8 presents how [RFC6775] and [RFC8505] are used; the       range of the ND status codes is narrowed down to 64 values, and       the unused bits are reserved. ------ Section 2. --- - s/Neighbor solicitation/Neighbor Solicitation/ - s/Information solicitation (DIS)/Information Solicitation (DIS)/ ------ Section 3. --- - s/The RPL Root tunnels the packets/The RPL Root tunnels data packets/  [unless we're talking about control packet] - s/forwards the original (inner) packet/forwards original (inner) packets/ ------ Section 4. --- - s/Neighbor solicitation (NS)/Neighbor Solicitation (NS)/ - s/6LN functionality in [RFC8505]/6LN functionality from [RFC8505]/ - Section 4.2.3 summarizes the main use case of the ROVR though its use here is a bit different: why not focus the paragraph on the latest sentence and bring a correct topic balance into the section? ------ Section 5. --- - s/with a CIO/with a 6CIO/ - s/the Root terminates the IP-in-IP tunnel at the parent 6LR/the IP-in-IP tunnel from the Root terminates at the parent 6LR/ ------ Section 6. --- - s/between the 6LR and the RPL Root/between the RPL Root and the 6LR/ - s/encodes it in one of these reserved flags of the RPL DODAG configuration option/allocates a new one in the RPL DODAG configuration option/ - s/values zero (0) to six (6)/values from zero (0) to six (6)/ ------ Section 7. --- - The section title should point to the draft title ("Efficient Route Invalidation") rather than the draft name which will be replaced by an RFC number at publication time. - s/hop by hop/hop-by-hop/ ------ Section 8. --- - Spacing inconsistency on the section title. ------ Section 9. --- - In section 9.2.2, the capital T is missing on "the" for steps 4 and 5. - s/Lifetime. e.g./Lifetime. E.g./ - s/6LoWPAN ND related reasons/6LoWPAN ND-related reasons/ - s/An error injecting the route/An error when injecting the route/ - In section 9.2.3, the capital T is missing on "the" for steps 2 and 3. ------ Section 11. --- - s/supporting th extension/supporting the extension/ ------ Section 12. --- - s/doesn't/does not/ ------ Regards, Julien _________________________________________________________________________________________________________________________ Ce message et ses pieces jointes peuvent contenir des informations confidentielles ou privilegiees et ne doivent donc pas etre diffuses, exploites ou copies sans autorisation.

the Routing Directorate reviewer for this draft. The Routing Directorate seeks to review all routing or routing-related drafts as they pass through IETF last call and IESG review, and sometimes on special request. The purpose of the review is to provide assistance to the Routing ADs. For more information about the Routing Directorate, please see http://trac.tools.ietf.org/area/rtg/trac/wiki/RtgDir Although these comments are primarily for the use of the Routing ADs, it would be helpful if you could consider them along with any other IETF Last Call comments that you receive, and strive to resolve them through discussion or by updating the draft. Document: draft-ietf-opsawg—l2nm-01 Reviewer: Yingzhen Qu Review Date: Dec 18, 2020 IETF LC End Date: N/A (early review) Intended Status: Standards Track Summary: There are some issues that should be at least considered prior to publication. Comments: Thanks for working on this draft. This is a big piece of work, and there are lots of details to be studied/verified. As an early review, I think the draft is heading to the right direction. I’ll continue to follow this draft (didn't have enough time to review the QoS part) and may provide more comments later. Regarding some of the open questions, here are my thoughts: - Per RFC4448, control-word is missing The function of control word is to sequence individual frames. RFC 4448 was defined more than 10 years ago, and most of today’s applications can support packets delivered out of order. I did a quick research, and it seems that most vendors still support the configuration of control word. But I’m wondering whether this should be in device model? If the authors want to include it in this network model, I’d suggest to add it with a default value. - Missing the option to re-write dot1q information received in access. - Should we see this as network level parameter or device level configuration parameters? This leads to a more general question. What’s the line between a network model and device models? It’s up to the authors and the WG to decide what to include in the model. Issues: Please add examples in appendix. What’s the relationship between vpn-svc-type and the type under signaling-options of vpn-node? They both are identityref of “vpn-common:vpn-signaling-type”. What will happen if they’re different values? Same for “container connection”, there is a “encapsulation-type”, then “l2-access-type” under “container dot1q-interface”, the relationship between these two types needs to be clarified. Section 4.2, the relation with network topology is a bit confusing. I know there is an expired draft: https://tools.ietf.org/html/draft-ogondio-opsawg-uni-topology-01, not sure whether it’s about this draft. So some clarifications will help. The following is actually imported from vpn-common module, but I see the authors are overlapping. If the admin-status is meant to be the enable and disable the VPN service since it is “rw”, I’d suggest to change the name to admin-state instead of status, this is confusing with the real status, and it’s typically “ro”. Also the “last-updated” may not be necessary for admin-status. uses vpn-common:service-status; +--rw status | +--rw admin-status | | +--rw status? identityref | | +--rw last-updated? yang:date-and-time | +--ro oper-status | +--ro status? identityref | +--ro last-updated? yang:date-and-time I feel the text/description in this draft could be improved and cleaned up, but I’m not a native speaker. Maybe RFC editor will help with this? There are names started with capital letter, but it’s not consistent in the draft, for example: service provider. Nits for your consideration: There are names started with capital letter, but it’s not consistent in the draft, for example: service provider. For IETF models, list name is normally plural. list vpn-node { key "vpn-node-id ne-id"; leaf vpn-node-id { type vpn-common:vpn-id; description <—— Please add a description here ""; } Typically list names are plural, so I’d suggest change “list vpn-service” to “list vpn-services”, same for “vpn-node”. “leaf Interface-mtu” should be “leaf interface-mtu” Typo in section 3.3.3.2.2, “This container is usedd to indicate”. The following list can be changed to a leaf-list: list peer-list { key "peer-ip"; leaf peer-ip { type inet:ip-address; description "Peer IP"; } description "List for peer IP"; } An extra “will” at section 4.3: Creating services in the l2vpn-ntw module will will lead at some From nobody Mon Dec 21 09:39:45 2020 Return-Path: X-Original-To: rtg-dir@ietfa.amsl.com Delivered-To:

as the Routing Directorate reviewer for this draft: PC= EP Procedures and Protocol Extensions for Using PCE as a Central Controller= (PCECC) of LSPs. The Routing Directorate seeks to review all routing or routing-related draf= ts as they pass through IETF last call and IESG review, and sometimes on sp= ecial request. The purpose of the review is to provide assistance to the Ro= uting ADs. For more information about the Routing Directorate, please see h= ttp://trac.tools.ietf.org/area/rtg/trac/wiki/RtgDir Although these comments are primarily for the use of the Routing ADs, it wo= uld be helpful if you could consider them along with any other IETF Last Ca= ll comments that you receive, and strive to resolve them through discussion= or by updating the draft. Document: draft-ietf-pce-pcep-extension-for-pce-controller-09 Reviewer: Victoria Pritchard Review Date: 22/12/2020 IETF LC End Date: Intended Status: Standards Track Summary: I have some minor concerns about this document that I think should be resol= ved before publication. Comments: The draft is generally very good and the diagrams are also very helpful. A few sections may initially cause a reader to be confused. I have sugg= ested some reorganisation of the text in case this is helpful. I also found a few things which were unclear, which could be clarified = in the document, and have included questions in the Minor issues section. Major Issues: No major issues found. Minor Issues: Section 5.4: I got confused reading this - the first part isn't clear but t= hen extra information is given, but it would be better to be clear from the= start... Here is some suggested text: --- During the PCEP Initialization Phase, PCEP Speakers (PCE or PCC) advertise = their support of and willingness to use PCEP extensions for PCECC using the= se elements in the OPEN message: o A new Path Setup Type (PST) in the PATH-SETUP-TYPE-CAPABILITY TLV to = indicate support for PCEP extensions for PCECC - TBD1 (Path is set up via P= CECC mode) o A new PCECC-CAPABILITY sub-TLV inside the PATH-SETUP-TYPE-CAPABILITY = TLV to indicate willingness to use PCEP extensions for PCECC o The STATEFUL-PCE-CAPABILITY TLV ([RFC8231]) (with the I flag set [RFC= 8281]) The new Path Setup Type is to be listed in the PATH-SETUP-TYPE-CAPABILITY T= LV by all PCEP speakers which support the PCEP extensions for PCECC in this= document. The new PCECC-CAPABILITY sub-TLV is included in PATH-SETUP-TYPE-CAPABILITY = TLV in the OPEN object to indicate willingness to use the PCEP extensions f= or PCECC during the established PCEP session. Using flags in this TLV, the = PCE shows the intention to function as a PCECC server, and the PCC shows wi= llingness to act as a PCECC client (see Section 7.1.1). If the PCECC-CAPABILITY sub-TLV is advertised and the STATEFUL-PCE-CAPABILI= TY TLV is not advertised, or is advertised without the I flag set, in the O= PEN Object, the receiver MUST: o Send a PCErr message with Error-Type=3D19 (Invalid Operation) and Err= or-value=3DTBD4 (stateful PCE capability was not advertised) o Terminate the session The PCECC-CAPABILITY sub-TLV SHOULD NOT be used without the corresponding P= ath Setup Type being listed in the PATH-SETUP-TYPE-CAPABILITY TLV. If it is= present without the corresponding Path Setup Type listed in the PATH-SETUP= -TYPE-CAPABILITY TLV, it MUST be ignored. If support and willingness are indicated by the PCE, but not by the PCC, th= e PCE MUST: o Send a PCErr message with Error-Type 10 (Reception of an invalid obje= ct) and Error-Value TBD2 (Missing PCECC-CAPABILITY sub-TLV) o Terminate the PCEP session If support and willingness is indicated by the PCC but not the PCE, the PCE= will ignore the capability. Unknown sub-TLVs are ignored in accordance wit= h [RFC8408] and [RFC5440]. If one or both speakers (PCE and PCC) have not indicated support and willin= gness to use the PCEP extensions for PCECC, the PCEP extensions for PCECC M= UST NOT be used. If a PCECC operation is attempted when both speakers have = not agreed in the OPEN messages, the receiver of the message MUST: o Send a PCErr message with Error-Type=3D19 (Invalid Operation) and Err= or-Value=3DTBD3 (Attempted PCECC operations when PCECC capability was not a= dvertised) o Terminate the PCEP session --- Question: If the PCE shows support and willingness, but the PCC doesn't, an= d the session is closed, would the PCE attempt a new session without the us= e of these extensions for PCECC? Question: If the PCC supports the extension but the PCE doesn't, is there a= lready text elsewhere that says unknown Path Setup Types can be ignored by = the PCE? The suggested text above may be wrong if not. Question: If the PCC does not support the PCECC extensions but the PCE atte= mpted to start a PCECC operation, will the PCC be able to send an error (th= e error mentioned implies support but not willingness)? Section 5.5.1 PCE-Initiated PCECC LSP: Again this section seems a bit jumbled, confusing at the start, but with re= -reading becomes clearer. Halfway down this section it says: "Note that the label forwarding instructions (see Section 5.5.3) from PCECC are sent after the initial PCInitiate and PCRpt message exchange with the ingress PCC." So the description above this, detailing the LSP-IDENTIFIER TLV and LSP obj= ect within the CCI, is not part of the first message exchange? If there nee= ds to be an initial exchange without CCI first, to get the PLSP-ID etc, to = put in the next set of PCInitiate messages, then this statement should go a= t the beginning of this section, maybe with a reference Figure 1, and state= any differences to the usual exchange. I think from re-reading, it means t= he initial exchange as per RFC 8281 is modified with Path Setup Type set to= TBD1, but still includes an LSP object (reserved PLSP-ID =3D 0, Delegate f= lag, SYMBOLIC-PATH-NAME TLV?) as in section 5.3 RFC 8281? The diagram Figure 1 is really helpful. A few references to it in the descr= iption may help, particularly to indicate the initial exchange, then the CC= I exchanges with all nodes, and describing in chronological order as shown = in the diagram would help. Section 5.5.3.1: What does it mean to "download the label" - does this just= mean to parse the message or does it imply some further processing? Section 5.5.4: This section also seems to be a little out of order. I would= remove the first sentence, start with the "make-before-break" procedure, m= ake it clear these instructions are sent to the transit and egress PCCs fir= st, then to the ingress PCC last. The diagram is again very good. Section 5.5.9: This is the first mention of the P flag - is this the same P= shown in the earlier diagrams? Should the flag have been mentioned earlier? Again the ordering could be improved. e.g. - PCE could allocate binding label on its own accord for a PCE-initiated or= delegated LSP, and inform the PCC in the PCInitiate message or PCUpd messa= ge by including P=3D1 and TE-PATH-BINDING TLV - PCE could request that the PCC allocates the binding label by setting P= =3D0 in the PCInitiate - If binding label is not supplied in PCInitiate, a PCC could request that = the PCE allocate it by including P=3D1 D=3D1 and TE-PATH-BINDING TLV (with = no Binding Value) in a PCRpt. The PCE would allocate the binding label ... In the capability exchange sections you mentioned error messages if someone= attempts an operation without declaring support and willingness to use tha= t capability - is there anything similar in case the binding label allocati= on is requested/allocated when the PCECC capability has not been agreed for= the session? Section 7.1.1 PCECC Capability sub-TLV: "Advertisement of the PCECC capability implies support of LSPs that are set= up through PCECC" However, earlier this draft stated that advertisement of the capability is = done using the path setup type, and that this PCECC capability TLV should n= ot be included without the PCECC type also being listed in the Path-Setup-T= ype list (and should be ignored if the path setup type is not listed). So i= n this section we should avoid potential conflict with the earlier statemen= t. Perhaps: "The PCECC-CAPABILITY sub-TLV is an optional TLV for use in the OPEN Object= in the PATH-SETUP-TYPE-CAPABILITY TLV, when the Path Setup Type list inclu= des the PCECC Path Setup Type TBD1. A PCECC-CAPABILITY sub-TLV MUST be igno= red if the PST list does not contain PST=3DTBD1." Should the new PATH-SETUP-TYPE be mentioned in the OPEN Object section too? To match earlier sections, this section could use the word "willingness" wh= en describing the L bit. Section 7.3: The C bit - does it mean the PCC sets the C bit to indicate it= has allocated the instruction rather than allocated the CC-ID - as far as = I understood it, the CC-ID comes from the PCE? Nits: Section 5.3: Brackets around the reference to section 7.3 seem like they sh= ould be around the rest of the sentence "(see Section 7.3 for the encoding = of the central controller instructions)." Section 5.5: Should the Path Setup Type TBD1 be mentioned, to clearly identify that PCEC= C LSP is intended? Is the requirement of the PATH-SETUP-TYPE TLV in these messages new? This c= ould be highlighted more clearly if so. This is the first time "SRP" has been used - should this be expanded? Kind regards, Victoria Pritchard.

Hello,

I have been selected as the Routing Directorate reviewer for this draft: PC= EP Procedures and Protocol Extensions for Using PCE as a Central Controller= (PCECC) of LSPs.

 

The Routing Directorate seeks to review all routing = or routing-related drafts as they pass through IETF last call and IESG revi= ew, and sometimes on special request. The purpose of the review is to provi= de assistance to the Routing ADs. For more information about the Routing Directorate, please see http://trac.tools.ietf.org/area/rtg/trac/wiki/RtgDir

Although these comments are primarily for the use of the Routing ADs, it wo= uld be helpful if you could consider them along with any other IETF Last Ca= ll comments that you receive, and strive to resolve them through discussion= or by updating the draft.



Document: draft-ietf-pce-pcep-extension-for-pce-controller-09
Reviewer: Victoria Pritchard
Review Date: 22/12/2020
IETF LC End Date:
Intended Status: Standards Track



Summary:

I have some minor concerns about this document that I think should be resol= ved before publication.



Comments:

    The draft is generally very good and the diagrams are also ve= ry helpful.

    A few sections may initially cause a reader to be c= onfused. I have suggested some reorganisation of the text in case this is h= elpful.

    I also found a few things which were unclear, which= could be clarified in the document, and have included questions in the Min= or issues section.



Major Issues:

    No major issues found.



Minor Issues:

Section 5.4: I got confused reading this - the first part isn't clear but t= hen extra information is given, but it would be better to be clear from the= start... Here is some suggested text:
---
During the PCEP Initialization Phase, PCEP Speakers (PCE or PCC) advertise = their support of and willingness to use PCEP extensions for PCECC using the= se elements in the OPEN message:

   o  A new Path Setup Type (PST) in the PATH-SETUP-TYPE-CAP= ABILITY TLV to indicate support for PCEP extensions for PCECC - TBD1 (Path = is set up via PCECC mode)
   o  A new PCECC-CAPABILITY sub-TLV inside the PATH-SETUP-T= YPE-CAPABILITY TLV to indicate willingness to use PCEP extensions for PCECC=
   o  The STATEFUL-PCE-CAPABILITY TLV ([RFC8231]) (with the = I flag set [RFC8281])

The new Path Setup Type is to be listed in the PATH-SETUP-TYPE-CAPABILITY T= LV by all PCEP speakers which support the PCEP extensions for PCECC in this= document.

The new PCECC-CAPABILITY sub-TLV is included in PATH-SETUP-TYPE-CAPABILITY = TLV in the OPEN object to indicate willingness to use the PCEP extensions f= or PCECC during the established PCEP session. Using flags in this TLV, the = PCE shows the intention to function as a PCECC server, and the PCC shows willingness to act as a PCECC client = (see Section 7.1.1).

If the PCECC-CAPABILITY sub-TLV is advertised and the STATEFUL-PCE-CAPABILI= TY TLV is not advertised, or is advertised without the I flag set, in the O= PEN Object, the receiver MUST:
   o  Send a PCErr message with Error-Type=3D19 (Invalid Ope= ration) and Error-value=3DTBD4 (stateful PCE capability was not advertised)
   o  Terminate the session

The PCECC-CAPABILITY sub-TLV SHOULD NOT be used without the corresponding P= ath Setup Type being listed in the PATH-SETUP-TYPE-CAPABILITY TLV. If it is= present without the corresponding Path Setup Type listed in the PATH-SETUP= -TYPE-CAPABILITY TLV, it MUST be ignored.

If support and willingness are indicated by the PCE, but not by the PCC, th= e PCE MUST:
   o  Send a PCErr message with Error-Type 10 (Reception of = an invalid object) and Error-Value TBD2 (Missing PCECC-CAPABILITY sub-TLV)<= br>    o  Terminate the PCEP session

If support and willingness is indicated by the PCC but not the PCE, the PCE= will ignore the capability. Unknown sub-TLVs are ignored in accordance wit= h [RFC8408] and [RFC5440].

If one or both speakers (PCE and PCC) have not indicated support and willin= gness to use the PCEP extensions for PCECC, the PCEP extensions for PCECC M= UST NOT be used. If a PCECC operation is attempted when both speakers have = not agreed in the OPEN messages, the receiver of the message MUST:
   o  Send a PCErr message with Error-Type=3D19 (Invalid Ope= ration) and Error-Value=3DTBD3 (Attempted PCECC operations when PCECC capab= ility was not advertised)
   o  Terminate the PCEP session
 
---
Question: If the PCE shows support and willingness, but the PCC doesn't, an= d the session is closed, would the PCE attempt a new session without the us= e of these extensions for PCECC?
Question: If the PCC supports the extension but the PCE doesn't, is there a= lready text elsewhere that says unknown Path Setup Types can be ignored by = the PCE? The suggested text above may be wrong if not.
Question: If the PCC does not support the PCECC extensions but the PCE atte= mpted to start a PCECC operation, will the PCC be able to send an error (th= e error mentioned implies support but not willingness)?


Section 5.5.1 PCE-Initiated PCECC LSP:

Again this section seems a bit jumbled, confusing at the start, but with re= -reading becomes clearer. Halfway down this section it says:
"Note that the label forwarding instructions (see Section 5.5.3) from<= br>    PCECC are sent after the initial PCInitiate and PCRpt message<= br>    exchange with the ingress PCC."

So the description above this, detailing the LSP-IDENTIFIER TLV and LSP obj= ect within the CCI, is not part of the first message exchange? If there nee= ds to be an initial exchange without CCI first, to get the PLSP-ID etc, to = put in the next set of PCInitiate messages, then this statement should go at the beginning of this section, = maybe with a reference Figure 1, and state any differences to the usual exc= hange. I think from re-reading, it means the initial exchange as per RFC 82= 81 is modified with Path Setup Type set to TBD1, but still includes an LSP object (reserved PLSP-ID =3D 0, Del= egate flag, SYMBOLIC-PATH-NAME TLV?) as in section 5.3 RFC 8281?

The diagram Figure 1 is really helpful. A few references to it in the descr= iption may help, particularly to indicate the initial exchange, then the CC= I exchanges with all nodes, and describing in chronological order as shown = in the diagram would help.

Section 5.5.3.1: What does it mean to "download the label" - does= this just mean to parse the message or does it imply some further processi= ng?

Section 5.5.4: This section also seems to be a little out of order. I would= remove the first sentence, start with the "make-before-break" pr= ocedure, make it clear these instructions are sent to the transit and egres= s PCCs first, then to the ingress PCC last. The diagram is again very good.

Section 5.5.9: This is the first mention of the P flag - is this the same P= shown in the earlier diagrams? Should the flag have been mentioned earlier= ?
Again the ordering could be improved. e.g.
- PCE could allocate binding label on its own accord for a PCE-initiated or= delegated LSP, and inform the PCC in the PCInitiate message or PCUpd messa= ge by including P=3D1 and TE-PATH-BINDING TLV
- PCE could request that the PCC allocates the binding label by setting P= =3D0 in the PCInitiate
- If binding label is not supplied in PCInitiate, a PCC could request that = the PCE allocate it by including P=3D1 D=3D1 and TE-PATH-BINDING TLV (with = no Binding Value) in a PCRpt. The PCE would allocate the binding label ...

In the capability exchange sections you mentioned error messages if someone= attempts an operation without declaring support and willingness to use tha= t capability - is there anything similar in case the binding label allocati= on is requested/allocated when the PCECC capability has not been agreed for the session?

Section 7.1.1 PCECC Capability sub-TLV:
"Advertisement of the PCECC capability implies support of LSPs that ar= e set up through PCECC"
However, earlier this draft stated that advertisement of the capability is = done using the path setup type, and that this PCECC capability TLV should n= ot be included without the PCECC type also being listed in the Path-Setup-T= ype list (and should be ignored if the path setup type is not listed). So in this section we should avoid = potential conflict with the earlier statement. Perhaps:
"The PCECC-CAPABILITY sub-TLV is an optional TLV for use in the OPEN O= bject in the PATH-SETUP-TYPE-CAPABILITY TLV, when the Path Setup Type list = includes the PCECC Path Setup Type TBD1. A PCECC-CAPABILITY sub-TLV MUST be= ignored if the PST list does not contain PST=3DTBD1."

Should the new PATH-SETUP-TYPE be mentioned in the OPEN Object section too?=

To match earlier sections, this section could use the word "willingnes= s" when describing the L bit.

Section 7.3: The C bit - does it mean the PCC sets the C bit to indicate it= has allocated the instruction rather than allocated the CC-ID - as far as = I understood it, the CC-ID comes from the PCE?



Nits:

Section 5.3: Brackets around the reference to section 7.3 seem like they sh= ould be around the rest of the sentence "(see Section 7.3 for the enco= ding of the central controller instructions)."

Section 5.5:
Should the Path Setup Type TBD1 be mentioned, to clearly identify that PCEC= C LSP is intended?
Is the requirement of the PATH-SETUP-TYPE TLV in these messages new? This c= ould be highlighted more clearly if so.
This is the first time "SRP" has been used - should this be expan= ded?


Kind regards,

Victoria Pritchard.

Document: draft-ietf-bess-evpn-proxy-arp-nd Reviewer: Ravi Singh Review Date: 21 Dec 2020 Intended Status: Standards track (as listed on the draft) Summary: This document is basically ready for publication, but has nits that should be considered prior to publication. Comments: The draft is generally well written and easy to understand. It basically is a description to explain how ARP, ND, EVPN should work together to reduce forwarding of ARP queries and/or NS messages, in an EVPN deployment, by the use of gratuitous ARP/ND. The abstract, though, could be made more direct by stating as such. Major Issues: none found. Minor Issues: none found. Nits: 1. Figure 1: please show which device owns IP3, for more clarity. 2. Section 4.6 (a): a. " IP moves before the timer expires (default value of N=5), it concludes that a duplicate IP situation has occurred. An IP move". It would be nice to elaborate on why the default value of "5" is recommended. Why not 1? Too much thrashing? However, for the cases where there is no thrashing, having a value of 5 as default slows the DAD procedure. Any recommendation on how to address that? b. Minor typo: " owner and spoofer keep replying to the CONFIRM message, the PE will detect the duplicate IP within the M timer:" -> " owner and spoofer keep replying to the CONFIRM message, the PE will detect the duplicate IP within the M-second timer:" 3. Biggest nit: the draft does not really specify any new messaging formats or any new fields. It is basically saying how the existing ARP, ND, EVPN messaging/machinery (should) work together to achieve flooding-minimization of ARP/ND queries in EVPN. Given the foregoing, it is not clear to me if the draft really should be considered "standards track" instead of "informational". The chairs are requested to evaluate that.

Comments: The document is easy to follow. It is a novel idea that solves a reasonable to understand problem. Major Issues: Nothing obvious. Minor Issues: Section 5: This it is proposed -> Thus it is proposed Section 6: large set of overlapping measurement type -> large set of overlapping measurement types "increased operation and capital cost" -> do you really want to make this claim? If so need to quantify it. Section 7.1: "when a packet had a delay relative to its predecessor of 2us both the up to 1us and the 2us counter" doesn't make sense. reword Section 7.2: "Characteristic’s 1 and 2" no apostrophe needed Section 7.3: "create a large demand on storage in the instrumentation system" -> quantify this if this claim is going to be made Section 9.1: "Editor’s Note we" - Clarify who 'we' is. The authors? the WG? don't use first person. Nits: A number of run-on sentences are in the document, especially in the Introduction. While not fatal, it makes it a chore to read in parts. Consider breaking some long sentences apart. There is a lack of comma usage throughout the document, a nit, but hurts readability.

The Routing Directorate seeks to review all routing or routing-related drafts as they pass through IETF last call and IESG review. The purpose of the review is to provide assistance to the Routing ADs. For more information about the Routing Directorate, please see http://trac.tools.ietf.org/area/rtg/trac/wiki/RtgDir. Although these comments are primarily for the use of the Routing ADs, it would be helpful if you could consider them along with any other IETF Last Call comments that you receive, and strive to resolve them through discussion or by updating the draft. Document: draft-ietf-pce-association-bidir-09.txt Reviewer: Harish Sitaraman Review Date: 30 December 2020 IETF LC End Date: 8 January 2021 Intended Status: Standards Track Summary: This document is basically ready for publication, but has nits that should be considered prior to publication. Comments: This document is clearly written. It required a closer read due to sentences that appear similar but differ on PCC/PCE (initiated/delegated). Major Issues: No major issues found. Minor Issues: Section 3.1 and 3.2: The last paragraphs refers to =E2=80=9CAs specified in [RFC8537]=E2=80=9D for the FRR procedures. From the title of the referred R= FC, it appears to be for co-routed LSPs though from the RFC sections 2.2.1/2.2.2, it is applicable for regular single-sided and double-sided LSPs too. Since this draft opts to mention FRR procedures and refers to RFC 8537 unchanged, would it be better to update section 3.3 too? Section 3.2.1: For readability, it might be better to clarify =E2=80=9CBoth endpoint (PCC) nodes report the forward LSP1 and LSP2 to the PCE.=E2=80=9D = as done in earlier section 3.1 to specifically call out reporting LSP1 by node A and LSP2 by node D. The sentence as is can be read as both nodes report both LSPs. Section 4.1: =E2=80=9CA Bidirectional LSP Association SHOULD NOT have more than two unidirectional LSPs.=E2=80=9D - it seems like this should be MUST NOT. Is there a reason why it shouldn=E2=80=99t be? Section 4.1: Were there any early allocation of IANA code points for this draft? I=E2=80=99m asking in relation to section 6.1 though technicall= y this is outside the scope of this document. Section 4.2: Is the F flag set if the forward LSP is not co-routed? If yes, an explicit statement will help, similar to how the C/R flags are clarified. Section 6.1: It is unclear what is the use of this section as there aren=E2=80=99t any details on the level of support or potential backwards compatibility issues once IANA assigns code points. I understand how that might be out of scope of this document, but I can=E2=80=99t find any u= se for this section as is. Maybe the section is a need from the WG perspective. Nits: Section 5.7: =E2=80=9CAssociations defined in this document and it does not support; the=E2=80=9D=E2=80=A6 misplaced ; instead of comma. Better to remo= ve =E2=80=9Cand it does not support;=E2=80=9D. Section 4.1: "Similarly, for both PCE Initiated and PCC Initiated single-sided case, these associations are also dynamically created on thee remote endpoint node using the information received from the RSVP message from the originating node." =3D> s/thee/the. In the first pass, I read it as three and was wondering if there is a 3rd endpoint node :-). -- Harish From nobody Thu Dec 31 13:59:33 2020 Return-Path: X-Original-To: rtg-dir@ietfa.amsl.com Delivered-To: rtg-dir@ietfa.amsl.com Received: from localhost (localhost [127.0.0.1]) by ietfa.amsl.com (Postfix) with ESMTP id 474753A0C15; Thu, 31 Dec 2020 13:59:27 -0800 (PST) X-Virus-Scanned: amavisd-new at amsl.com X-Spam-Flag: NO X-Spam-Score: -2.1 X-Spam-Level: X-Spam-Status: No, score=-2.1 tagged_above=-999 required=5 tests=[BAYES_00=-1.9, DKIM_SIGNED=0.1, DKIM_VALID=-0.1, DKIM_VALID_AU=-0.1, DKIM_VALID_EF=-0.1, FREEMAIL_FROM=0.001, NICE_REPLY_A=-0.001, SPF_HELO_NONE=0.001, SPF_PASS=-0.001] autolearn=ham autolearn_force=no Authentication-Results: ietfa.amsl.com (amavisd-new); dkim=pass (2048-bit key) header.d=gmail.com Received: from mail.ietf.org ([4.31.198.44]) by localhost (ietfa.amsl.com [127.0.0.1]) (amavisd-new, port 10024) with ESMTP id b5-QNJK8P0QS; Thu, 31 Dec 2020 13:59:26 -0800 (PST) Received: from mail-pg1-x532.google.com (mail-pg1-x532.google.com [IPv6:2607:f8b0:4864:20::532]) (using TLSv1.2 with cipher ECDHE-RSA-AES128-GCM-SHA256 (128/128 bits)) (No client certificate requested) by ietfa.amsl.com (Postfix) with ESMTPS id 222563A0C12; Thu, 31 Dec 2020 13:59:26 -0800 (PST) Received: by mail-pg1-x532.google.com with SMTP id n25so13693442pgb.0; Thu, 31 Dec 2020 13:59:26 -0800 (PST) DKIM-Signature: v=1; a=rsa-sha256; c=relaxed/relaxed; d=gmail.com; s=20161025; h=subject:to:cc:references:from:message-id:date:user-agent :mime-version:in-reply-to:content-language:content-transfer-encoding; bh=kC+MHMN5gN02Pp5jXAq1mbDypZ03RE0udQBgOfmeQYo=; b=srrkeBD6fjL6CLwHOK1PQGn5hgRa5W35aWyZXFh457WF8iKK54JOy+rM2qABFrj73X r6MPS/8U7QvwD9p0oh0cl9X1J3qgVWBrvqpPmy3h+5FP2Njb/+hJQODbQjpAeh9uZQWn cIS7cwFWy2uZPKxXtpnjw5zIg05pLOM0GtQubg1PwoB6rr/ejzKCdWwvh1NLqbFYNV+8 LlnGNruBN0+tAin1yBso+fkhyiH8oY4PCx6lY3rBihto7FePE60KwzfFiUg9K+DP3HE+ cAlIX6Ab9ixvbMfzKKRidf8AJcavtsYkZ9EQuBPLTS2wyRlo2q2N0rnKaBGSb8lwC1pG bYxQ== X-Google-DKIM-Signature: v=1; a=rsa-sha256; c=relaxed/relaxed; d=1e100.net; s=20161025; h=x-gm-message-state:subject:to:cc:references:from:message-id:date :user-agent:mime-version:in-reply-to:content-language :content-transfer-encoding; bh=kC+MHMN5gN02Pp5jXAq1mbDypZ03RE0udQBgOfmeQYo=; b=rM7DnBVQnT3kCVU44g0XhUFq6h9GY9FR/vskgM2c0zMF7a2Admp07T4prjhYwvbbK/ TXZtejRkyZafiCazQDvgHnXuZXoWiX/2ynNlnvd+gWMowiocxuV4EmOjWe0OFQ2gbSdJ fihu6Ao1l3yo/LITT97uMcVONFOGTEWjngAcABZC29Evkqr+6UdzvleWksT3ScnXUzmu 5BhcXJgjP3wdjQeil1RWa4+OE8N76w8zEyS+NfWetpOIkxood9/Z1WdjNsfX3aploPjG E9Ap87yx3nvOZcvbSddNAsbltFAZsA1zwbr7vkSIhIbJq1nYxP5sP2Wfg4Wm9Q+LTBy3 U6zg== X-Gm-Message-State: AOAM533/JUkNIe+ST7CgsILNUccePJ3NlM/vKcOiIUBdenWtMB8cTOCk FpJdHm4+bkdzgiY0eI3x/3aCrmpJqkVyTA== X-Google-Smtp-Source: ABdhPJylmQnfjbpE3wxDgHQduRcK/+MHXYB472jMSkHuEPL8v3GhESGujRcM6SoKLPDpi9fQG5CCEA== X-Received: by 2002:a05:6a00:14d1:b029:19d:d135:bacf with SMTP id w17-20020a056a0014d1b029019dd135bacfmr32940258pfu.12.1609451965151; Thu, 31 Dec 2020 13:59:25 -0800 (PST) Received: from [192.168.178.20] ([151.210.131.28]) by smtp.gmail.com with ESMTPSA id ck20sm11864614pjb.20.2020.12.31.13.59.22 (version=TLS1_2 cipher=ECDHE-ECDSA-AES128-GCM-SHA256 bits=128/128); Thu, 31 Dec 2020 13:59:24 -0800 (PST) To: Ines Robles , rtg-dir@ietf.org Cc: draft-carpenter-eligibility-expand.all@ietf.org, last-call@ietf.org References: <160917958338.19537.15496707626331067977@ietfa.amsl.com> From: Brian E Carpenter Message-ID: <18acc256-8dbd-aa40-be11-b069c4b5786d@gmail.com> Date: Fri, 1 Jan 2021 10:59:19 +1300 User-Agent: Mozilla/5.0 (Windows NT 10.0; WOW64; rv:60.0) Gecko/20100101 Thunderbird/60.9.1 MIME-Version: 1.0 In-Reply-To: <160917958338.19537.15496707626331067977@ietfa.amsl.com> Content-Type: text/plain; charset=utf-8 Content-Language: en-US Content-Transfer-Encoding: 7bit Archived-At: Subject: Re: [RTG-DIR] Rtgdir last call review of draft-carpenter-eligibility-expand-08 X-BeenThere: rtg-dir@ietf.org X-Mailman-Version: 2.1.29 Precedence: list List-Id: Routing Area Directorate List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Thu, 31 Dec 2020 21:59:27 -0000 Ines, Thanks for the review.
