be a challenge to carry even two parent addresses in the PS= . There has been a

Regardless, I feel we should do it if we want this to b= e a practical

o Section 3.4 Usage:
"For exa= mple, using different methods can be used to vary the transmission

other policy only when= the strict policy cannot be used given their parent sets.
The above sta= tement implies that nodes may still go for a relaxed policy when

The parameters warrant a rationale and a default = value. Also more importantly,
is it required that different nodes use th= e same value and if not what could be
the impact.

o Terminology s= ection
Terminology section should explain Alternative Parent, Parent Set= , Preferred

o Section realignment
It is better t= o explain CA Strict/Medium/Relax policies before explaining the

The proposition by Unaware-leaves draft wrt RPL status is: Use of RPL status to carry ND status. ND Status (RFC 8505) is 8bits, and RPL status is 8bits. RPL status MSB is already used to indicate outright rejection. Unaware-leaves draft dedicates 2nd MSB in RPL status to indicate ND status. This means only lower 6-bits of ND Status can be at most carried in RPL status. The RPL Status carrying ND Status seems not adequate, 1) RPL Status can carry only lower 6bits of the 8bits of ND Status 2) RPL Status and ND Status may not always be correlated. How about using a different ND Option in RPL messaging to keep the ND handling segregated? The unaware draft can say that this option can be carried in DCO or any other RPL message it requires. ND status/option may have to be carried only in specific cases which involves unaware leaves and as such the control overhead due to option header may not be much. This ND option could also be easily extended for future purposes since we may have additional fields in the future from ND to be carried with RPL.

It's actually cool that the way we = defined now does not need to be aware of each value to do a mapping so the = status can be transported transparently without changing a RPL spec each ti= me ND changes (thanks to Alvaro).

We started with a mapping and Alvaro reacted to that. So we proposed t= he encapsulation that you describe. And now we'd have an new option? This s= eems really excessive when each bit counts. Note that so far there is not a= single RPL status defined outside of those imported from ND, and each DAO-= ACK is carrying 8 bits of zeroes all around the world in millions of device= s. We better not increase the waste don't you think? > This ND option could also be easily extended for future purposes since we= may > have additional fields in the future from ND to be carried with RPL. =20 RPL and ND are close family, RPL is effectively the way to support non-tran= sit links (NBMA) that the original ND did not have. RPL carries ND options = natively, consider PIO. I'm all for adding more options like SLLAOs in DIO,= as we discussed at the meeting. So I fully agree with the desire/intuition= . But we do not need an ND option for that, it's already meant to be this w= ay. What do others think?

ND Status (RFC 8505) is 8bits, Forgive my slowness, new documents don't always seep into my brain quickly. Is this RFC8505 section 9.4, ARO Status Values? I can't find ND status in 8505 :-) I re-read section 7 of unaware leaves, but I'm afraid I'm having difficulties knitting all the pieces together.

But yes, these are indeed ND (E)ARO status codes. Sorry for the confusion. > I re-read section 7 of unaware leaves, but I'm afraid I'm having difficulties > knitting all the pieces together. [RJ] I think the 'A' bit in section 7 which says that the RPL status is originated from ND EARO is the central point here. ND is using RPL's base object Status field to propagate its status. RPL Status field is getting used as of now in, DAO-ACK [RFC6550] and DCO [efficient-route-invalidation draft]. My reason to start this discussion was to clarify the intersection between ND/RPL to WG and the conclusion of this discussion will lead to another mail wherein I would like to propose final changes to DCO's Moved status value (which is currently 130).

The Ockham's razor of the day is probably energy conservation. We have a RP= L status that uses 8 bits and has no value defined. We need to transport th= e EARO status to map between RPL and ND (for RUL and BBR). Should we insert= a new field or merge the RPL and ND status. So far we went from the merge.= Initially it was a mapping but Alvaro's review made us change that. Now it= is an implicit transport of ND status inside RPL status, with the caveats = that Rahul points out, mostly that the RPL status only has 6 bits to transp= ort the EARO status that is 8 bits at this moment. My suggestion to solve this is to reduce the size of the EARO status on the= next occasion, which will free 2 bits for ND use in the EARO, and in the m= eantime ensure that values > 63 are not assigned at IANA review. We can wri= te a quick fix at 6lo if that helps feel better.

Dear all

 

Going through our last meeting = (https://www.yout= ube.com/watch?v=3D3UiF5FDAEjA) around 1:40, we discussed the way we can= recover the configuration bits used by use-of-rpl-info and turnon-rfc8138.

 

The proposal on the table was:<= o:p>

- change turnon-rfc8138 to say = that the configuration bit only applies to MOP < 7 (RPL v1)

- use-of-rpl-info is edited to = say the same thing

- we create a IANA registry wit= h a MOP column so the bits depend on the MOP. MOPext could be the place for= introducing this registry.

 

I’d like to check if the = ML is in line with this approach.

 

All the best<= /p>

Dec 2019 13:37:58 -0000 Dear all Going through our last meeting (https://www.youtube.com/watch?v=3D3UiF5FDAE= jA) around 1:50, we discussed the whether the use of RFC 8138 in a P-Dao ro= ute is inherited from the use of the main DAG. One argument is that it should be generalized anyway so do not spend config= uration bits on this. Another that was not discussed is that a P DAO route may span over multiple= DAGs. What if they do not agree on use of RFC 8138? The proposal on the table was: a) P DAO refers to both daft normatively to indicate that the projected rou= te inherits from the substrate b) indicate in the P DAO message whether to turn on RFC 8138 on a per route= basis What's best?

The proposal on the table was:<= u>

- change turnon-rfc8138 to say = that the configuration bit only applies to MOP < 7 (RPL v1)

- use-of-rpl-info is edited to = say the same thing

- we create a IANA registry wit= h a MOP column so the bits depend on the MOP. MOPext could be the place for= introducing this registry.

=C2=A0

I=E2=80=99d like to check if th= e ML is in line with this approach.


[RJ] I am inline with these points.

X-List-Received-Date: Thu, 12 Dec 2019 09:36:15 -0000 > [Rahul asked] I would like to confirm a point here... Reclaiming the turn= on-8138 flag in MOP>=3D7 would mean that 8138 is _mandatorily_ supported in= the nodes above MOP>=3D7 such that they no more depend on this flag. This = in itself is a bigger decision! Is my understanding correct? While the adva= ntages of 8138 are obvious in non-storing MOP case, they are less impacting= /obvious in storing MOP case.=A0 The configuration bits can be reclaimed if the value is always-on or always= off for a new MOP. When defining a MOP, it is possible to indicate either = way and then to reclaim the bits. I see that MOPext could say, individually= for each bit: a) For any MOP >=3D 7, the bit is implicitly always on (or off) unless the = MOP specification says otherwise b) For any MOP >=3D 7, the MOP specification MUST either indicate that the = bit is used as for MOP<7 or provide an implicit setting c) For any MOP >=3D 7, the bit is implicitly as for MOP<7 unless the MOP sp= ecification says otherwise My preference goes to a), defaulting both settings to on. My rationale is t= his: . A default value simplifies the writing of the MOP specs. . For the RPI option type, we deprecated the value 0x63 and RPLv2 seems lik= e a good flag day. I expect that no MOP > 7 will ever turn it back on. But = if we were wrong doing this, then a MOPext bis can always reverse the defau= lt above another step of MOP. . For the RFC 8138 turnon bit, even in storing mode, there's IP in IP for p= ackets coming from the outside to insert a HbH header, and compressing thos= e 2 is already a huge saving. I'd also argue that all known implementations= for constrained environments support non-storing, so the code should be th= ere. I'm not sure it's a huge footprint in the devices, considering the val= ue in each packet, it's certainly worth it. Finally, the nex RPL signaling = (P DAO and RUL) already uses RFC 8138 to compress the RPL control packets. What do other think?

I agree that it is a bigger decision. I also think that it's tying RPL to 802.15.4/6lo a lot too! So, let me attempt to rephrase it. For MOP >= 7, the bits being reclaimed, and that bit does not indicate turnon-8138.

This draft is a work item of the Routing Over Low power and Lossy networks WG of the IETF. Title : Using RPI Option Type, Routing Header for Source Routes and IPv6-in-IPv6 encapsulation in the RPL Data Plane Authors : Maria Ines Robles Michael C. Richardson Pascal Thubert Filename : draft-ietf-roll-useofrplinfo-33.txt Pages : 56 Date : 2019-12-13 Abstract: This document looks at different data flows through LLN (Low-Power and Lossy Networks) where RPL (IPv6 Routing Protocol for Low-Power and Lossy Networks) is used to establish routing. The document enumerates the cases where RFC6553 (RPI Option Type), RFC6554 (Routing Header for Source Routes) and IPv6-in-IPv6 encapsulation is required in data plane. This analysis provides the basis on which to design efficient compression of these headers. This document updates RFC6553 adding a change to the RPI Option Type. Additionally, this document updates RFC6550 defining a flag in the DIO Configuration Option to indicate about this change and updates RFC8138 as well to consider the new Option Type when the RPL Option is decompressed. The IETF datatracker status page for this draft is: https://datatracker.ietf.org/doc/draft-ietf-roll-useofrplinfo/ There are also htmlized versions available at: https://tools.ietf.org/html/draft-ietf-roll-useofrplinfo-33 https://datatracker.ietf.org/doc/html/draft-ietf-roll-useofrplinfo-33 A diff from the previous version is available at: https://www.ietf.org/rfcdiff?url2=draft-ietf-roll-useofrplinfo-33 Please note that it may take a couple of minutes from the time of submission until the htmlized version and diff are available at tools.ietf.org.

For Use of RPL= info I propose the following addition

"

Section 6.3.1. of <xref target=3D"RFC6550"/> defines a 3-bi= t Mode of
Operation (MOP) in the DIO Base Object. The flag is defined only
for MOP value between 0 to 6. For a MOP value of 7 or above, the flag
MAY indicate something different and MUST NOT be interpreted as
"RPI 0x23 enable" unless the specification of the MOP
indicates to do so.

"

I created a pull request to the authors. The pull request also proposes som= e clean up since the original text really abuses terms like "RPI value= ".
The RPI is an abstract data defined in RFC 6550. RFC 6553 defines a RPL Opt= ion. 0x63 is the value of the Option Type field of the RPL Option. I change= d the draft to use "RPI" in abusive replacement of "RPL Opti= on" so we can use " RPI Option Type" but kept the abuse at t= hat.

Ines: You author section does not compile well, if you could look at it as = well?

All the best

Pascal

Subject: Re: [Roll] Reclaiming the bits

=C2=A0
The proposal on the table was:
- change turnon-rfc8138 to say that the configuration bit only applies to M= OP < 7 (RPL v1)
- use-of-rpl-info is edited to say the same thing
- we create a IANA registry with a MOP column so the bits depend on the MOP= . MOPext could be the place for introducing this registry.
=C2=A0
I=E2=80=99d like to check if the ML is in line with this approach.

[RJ] I am inline with these points.
I would like to confirm a point here... Reclaiming the turnon-8138 flag in = MOP>=3D7 would mean that 8138 is _mandatorily_ supported in the nodes ab= ove MOP>=3D7 such that they no more depend on this flag. This in itself = is a bigger decision! Is my understanding correct? While the advantages of = 8138 are obvious in non-storing MOP case, they are less impacting/obvious i= n storing MOP case.=C2=A0

Dear all

 

Looking at https://www.youtube.com/watch?v=3D3UiF5FDAEjA around t=3D22mn, there wa= s Rahul’s question about 6LR and compression.

The existing text had a lowerca= se should. I suggest to MUST it as follows:

 

   Additionally, the = RUL is not expected to support the compression method

   defined in [RFC813= 8]. The 6LR that injected the route <change> MUST </change>

   uncompress the pac= ket before forwarding over an external route, even when

   delivering to a RU= L, even when it is not the destination in the outer header

   of the incoming pa= cket, unless configured to do otherwise.

 

 

Does that work?

 

I believe the document is ready= fo WGLC… is there anything missing?

 

All the best<= /p>

Richardson Filename : draft-ietf-roll-unaware-leaves-08.txt Pages : 31 Date : 2019-12-16 Abstract: This specification extends RFC6550 and RFC8505 to provide unicast and multicast routing services in a RPL domain to 6LNs that are plain Hosts and do not participate to RPL, and enables the RPL Root to proxy the EDAR/EDAC flow on behalf of the RULs and RANs in its DODAG.

The argument on the WG list with authors was WHY that use of reserved (important question), IMO they did not answer that but asked for another proposal. Usually IMHO if we get a proposal we discuss that one proposal and find ways to modify and answer question of why it was designed that way, because we are working as an ietf group not as individuals.

Dear all,

The call for WG adoption of draft-thubert-roll-turnon-rfc8138 has been= open since Nov 19th.
Based on the reaction at the WG meeting in Singapore (IETF106) and on = the mailing list after that, the WG chairs declare consensus on the matter.=
Therefore, Pascal, can you please republish the draft as a WG document= ?

For the record:
  • There were positive opinions, including from people who actively contri= bute to the writing of drafts at ROLL and related WGs, and who contribute t= o developing or evaluating their implementations.
  • There was one opp= osition, arguing that RFC8138 turn on should be done another way.=C2=A0
  • = There is no substantiated technical proposal on the table other than draft-= thubert-roll-turnon-rfc8138.

Well that's an open discussion of positioning RPL and ND.=20 For the case of adding ND options in DIOs, e.g., SLLAO, this does not help= a RUL since the RUL does not parse the DIO messages. Not sure what your point is though?

IF we do it this way, future extensions to ND ARO status need to consider whether they are applicable to RPL and define accordingly. This implies familiarity in 6lo/6MAN with RPL. I prefer the other approach where we restrict the ND ARO status to 64bits itself. Anyways using 128 bits in the future seems far-fetched (as indicated by Pascal before). But to limit ND ARO status to 64bits we need to convince the 6lo/6MAN group that "because of RPL" we need to reduce the size. I am not sure if this is easy to digest!

The argument on the WG list with authors was WHY that use of reserved (= important question), IMO they did not answer that but asked for another pro= posal. I was skeptical too about using a reserved bit in DIO Config option for handshaking a compression flag. But the proposition of using the reserved bit for MOP<7 made sense to me. We certainly can't set this flag in DIO base object or any other place in DIO. The reserved bit is part of DIO Configuration option, and the indication of compression flag also is a form of DAG-wide configuration. Thus it fits ok principally too! Anyways, it would be interesting to learn of other ways from the WG. 8138 is useful and for it to be put to use in existing networks, such a flag/compression handshake is necessary.

A "RPL Leaf can correctly receive a packet with RPL artifacts", which I assume it means that it implements RPL, at least enough to understand the artifacts even if it doesn't generate them. =C2=A0 OTOH, a RPL-unaware-node "does not implement RPL". =C2=A0But then a RUL is "a RPL-unaware-node that is also a RPL Leaf". =C2=A0This last definition sounds contradictory to me because the RPL Lead has to implement enough of RPL to understand, but being unaware.... ... 303 4.1. =C2=A0Updates to RFC6550: Advertising External Routes with Non-Sto= ring 304 =C2=A0 =C2=A0 =C2=A0Mode Signaling. ... 347 =C2=A0 A node that is reachable over an external route is not expected= to 348 =C2=A0 support [RFC8138]. =C2=A0Whether a decapsulation took place or = not and 349 =C2=A0 even when the 6LR is delivering the packet to a RUL, the 6LR th= at 350 =C2=A0 injected an external route MUST uncompress the packet before 351 =C2=A0 forwarding over that external route. If the packet is not decapsulated, how can it be uncompressed? ... 672 6. =C2=A0Use cases ... 800 =C2=A0 =C2=A0 =C2=A0- In the uses cases, we assume that the RAL suppor= ts IP-in-IP 801 =C2=A0 =C2=A0 =C2=A0encapsulation. 803 =C2=A0 =C2=A0 =C2=A0- In the uses cases, we dont assume that the RUL s= upports IP-in-IP 804 =C2=A0 =C2=A0 =C2=A0encapsulation. Please reword these two assumptions to avoid the use of "we".

Reclaimin= g the turnon-8138 flag in MOP>=3D7 would mean that 8138 is _mandatorily_= supported in the nodes above MOP>=3D7 such that they no more depend on = this flag. This in itself is a bigger decision! Is my understanding correct= ? While the advantages of 8138 are obvious in non-storing MOP case, they ar= e less impacting/obvious in storing MOP case.=C2=A0

The configuration bits can be reclaimed if the value is always-on or always= off for a new MOP. When defining a MOP, it is possible to indicate either = way and then to reclaim the bits. I see that MOPext could say, individually= for each bit:

a) For any MOP >=3D 7, the bit is implicitly always on (or off) unless t= he MOP specification says otherwise

b) For any MOP >=3D 7, the MOP specification MUST either indicate that t= he bit is used as for MOP<7 or provide an implicit setting

c) For any MOP >=3D 7, the bit is implicitly as for MOP<7 unless the = MOP specification says otherwise

My preference goes to a), defaulting both settings to on. My rationale is t= his:

.. A default value simplifies the writing of the MOP specs.

.. For the RPI option type, we deprecated the value 0x63 and RPLv2 seems li= ke a good flag day. I expect that no MOP > 7 will ever turn it back on. = But if we were wrong doing this, then a MOPext bis can always reverse the d= efault above another step of MOP.

.. For the RFC 8138 turnon bit, even in storing mode, there's IP in IP = for packets coming from the outside to insert a HbH header, and compressing= those 2 is already a huge saving. I'd also argue that all known implem= entations for constrained environments support non-storing, so the code sho= uld be there. I'm not sure it's a huge footprint in the devices, co= nsidering the value in each packet, it's certainly worth it. Finally, t= he nex RPL signaling (P DAO and RUL) already uses RFC 8138 to compress the = RPL control packets.

What do other think?

I did not agree wi= th this use of config bit in the first place and said it is complicated, as= you can see authors are confused. However, I think it is not useful to mak= e that=C2=A0 configuration bit depending on MOP,, the best practise is sepa= rate both as independent.

Great efforts! Please find my co= mments below for your consideration. 1. Why do you choose to extend RPL instead of designing a new separate prot= ocol to realize the establishment of a path? Technically, extending RPL wor= ks for sure. But if you look outside the IOT domain, the PCE have a separat= e protocol, i.e. PCEP, to establish the paths on the devices.=20 2. The titles of the subsections in section 6 are misleading. When I looked= at the title "Non-storing/Storing mode projected route", I misunderstood t= hem into "Route projection in non-storing/storing mode". Actually, until I = reached at the appendix, I realized that they means the projected route its= elf is source-routed or hop-by-hop (no matter strict or loose). Do you thi= nk it is necessary to add some clarification or to change the titles? 3. The following specification is not accurate in some cases: " In the unco= mpressed form the source of the packet would be self, the destination would= be the first Via Address in the SRVIO, and the SRH would contain the list = of the remaining Via Addresses and then the Target". It is true if RPL is running in storing mode, otherwise, another encapsulat= ion takes place to indicate the explicit route to the via address, just lik= e you have said in the preceding paragraph.

Yes, of course. =C2=A0That is also in fact what you wrote in the text. It is now clear to me -- no further changes needed for that part. :-) Thanks! Alvaro.

Please correct me if I mis-understood. > [RJ] Currently ND has 8bits to store 256 values ... RPL needs to carry the same 8-bits but currently it has space only for 6-bits in RPL Status field. But as of now only few values of ND status has been used and using up 256 values (or for that matter 64 values) seem far-stretched. Thus one of the opinions is to limit the ND status to 64-bits and carry as-is in the RPL status.
