"Sequence Number"

- what happens when the counter wraps? Are you okay to start at zero again = -
but zero has a special meaning. Wrapping back to "1"?  The d= raft should
define what comes after 2^32 - 1.

- would is make sense to have the mechanism always running, including
Down/Init packets? The Down-Init-Up can happen rapidly, what about deugging=
packet loss during this sequence?


"Security Consideration"

- I don't think that saying "well, it's either us or crypto-authentica= tion"
is a good statement for IETF. Especially with the effort to make
authentication more realistic for BFD (like draft-mahesh-bfd-authentication= )
it's not forward-looking. You could at least outline how every existing authentication could be "cloned" to have the new fields you intro= duce, to
allow for both packet loss counting and authentication.

I support this idea. There are implementations that drop BFD packets with t= he
A bit set (as no authentication is supported in the implementation). I'm al= so
not sure how quickly hardware-based BFD implementations can be upgraded. So=
for backward compatibility it would be good to be able to turn it off.

Use case is in WGLC and we're just trying to resolve the last nits there before sending it off to the IESG. I agree - we're probably at the point of initiating a WGLC on the base and IP documents.

The chairs decision was that in light of the more extensive review from Eric Gray, we had enough coverage to progress the document. In order to give the working group a chance to re-review any changes, we will include this document in the batch of documents in WGLC ending on May 15.

--_000_D16FD2842C0B5mmudigonciscocom_ Content-Type: text/plain; charset="Windows-1252" Content-Transfer-Encoding: quoted-printable Hi Santosh/Authors, A couple of questions: 1. It is not clear if this draft is addressing both VM to VM and VTEP to= VTEP verification through BFD. I assume it is both. 2. If the VMs are Layer 2 only, then what is the inner IP address (espec= ially source IP)? I understand that outer IP is going to carry the VTEPs ad= dresses. 3. Why is the inner IP destination address 127/8 or 0:0:0:0:0:FFFF:7F00/= 104? I understand that it is to avoid the packet being routed but, how can = an IP packet addressed to a particular VTEP be consumed by any other node i= n the network and then route the inner payload? 4. The service node=92s use case is not very clear. Mat be you can add a= little bit of details here. 5. I understand that VTEP knows that the packet is to be terminated at t= he VTEP based on TTL being 1. What about the case of VM to VM BFD? What sho= uld be the TTL value here? Is it 255 or something different? It is hardco= ded to =931" in the draft. 6. Since we are using a destination UDP port of 3784, shouldn=92t the TT= L be 255 to be consistent with the RFC 5880? If you have these covered in the draft already, please point me to the appr= opriate sections. Thanks Regards Mallik From: "Vengada Prasad Govindan (venggovi)" > Date: Wednesday, 6 May 2015 9:39 am To: Santosh P K >, "rtg= -bfd@ietf.org" > Subject: RE: New Version Notification for draft-spallagatti-bfd-vxlan-00.tx= t Hello Santosh/ Authors, Thanks for sharing the document, please find a few thoughts below. 1. The current document talks about both BFD and S-BFD - would it be benefi= cial to make separate documents for BFD and SBFD to maintain consistency wi= th the current set of documents. 2. Motivation: It would be nice to state the requirements or motivation tha= t this draft addresses, i.e. what problems does this draft address that can= not be solved using the existing BFD/ SBFD protocol treating the VxLAN as a= tunnel/ underlay transport transparent to BFD. I would submit that BFD ove= r VxLAN not be treated along the same lines of BFD over MPLS or BFD for PW = (VCCV) given the differences in the nature of the transport between MPLS an= d VxLAN. 3. Inner Ethernet header: The document does not address the contents of the= Inner Ethernet header (present after the VxLAN header). This needs to be s= pecified. 4. Destination IP: The document mandates that this needs to be 127/8. What = disadvantages do you observe if the DIP were to be the IP of the destinatio= n VTEP? When using 127/8 as the DIP. one problem is that there is no indica= tion of the intended DIP of the BFD session by using 127/8. What if the nod= e at which the VxLAN tunnel is (prematurely) terminated happens to support = BFD? It may be better to use the IP address of the Destination VTEP as the = DIP. 5. Inner TTL: For the same reasons discussed in (2), why does the document = mandate this to be set to 1? 6. It may be beneficial to run a spell-checker to fix typos in the document= . I request the authors/ WG to comment on the above aspects.

Hi Santosh/Authors,

A couple of questions:
  1. It is not clear if this draft is addressing both VM to VM and VTEP to V= TEP verification through BFD. I assume it is both.
  2. If the VMs are L= ayer 2 only, then what is the inner IP address (especially source IP)? I un= derstand that outer IP is going to carry the VTEPs addresses. 
    3. Why is the inner IP destination address 127/8 or 0:0:0:0:0:FFFF:7F00/104? = I understand that it is to avoid the packet being routed but, how can an IP= packet addressed to a particular VTEP be consumed by any other node in the= network and then route the inner payload?
  3. The service node=92s use case is not very clear. Mat be y= ou can add a little bit of details here.
  4. I understand that VTEP kno= ws that the packet is to be terminated at the VTEP based on TTL being 1. Wh= at about the case of VM to VM BFD? What should be the TTL value here?  = ; Is it 255 or something different? It is hardcoded to =931" in the dr= aft.
  5. Since we are using a destination UDP port of 3784, shouldn=92t= the TTL be 255 to be consistent with the RFC 5880? 
If you have these covered in the draft already, please point me to the= appropriate sections.

Thanks

Regards
Mallik

Subject: RE: New Version Notificati= on for draft-spallagatti-bfd-vxlan-00.txt

Hello Santosh/ Authors,
Thanks for sharing the document, please find a few thoughts below.
1. The current document talks about both BFD and S-BFD - would it be b= eneficial to make separate documents for BFD and SBFD to maintain consisten= cy with the current set of documents.
2. Motivation: It would be nice to state the requirements or motivatio= n that this draft addresses, i.e. what problems does this draft address tha= t cannot be solved using the existing BFD/ SBFD protocol treating the VxLAN= as a tunnel/ underlay transport transparent to BFD. I would submit that BFD over VxLAN not be treated alon= g the same lines of BFD over MPLS or BFD for PW (VCCV) given the difference= s in the nature of the transport between MPLS and VxLAN.
3. Inner Ethernet header: The document does not address the contents o= f the Inner Ethernet header (present after the VxLAN header). This needs to= be specified.
4. Destination IP: The document mandates that this needs to be 127/8. = What disadvantages do you observe if the DIP were to be the IP of the desti= nation VTEP? When using 127/8 as the DIP. one problem is that there is no i= ndication of the intended DIP of the BFD session by using 127/8. What if the node at which the VxLAN tunnel= is (prematurely) terminated happens to support BFD? It may be better to us= e the IP address of the Destination VTEP as the DIP.
5. Inner TTL: For the same reasons discussed in (2), why does the docu= ment mandate this to be set to 1?
6. It may be beneficial to run a spell-checker to fix typos in the doc= ument.
I request the authors/ WG to comment on the above aspects.
Thanks
Prasad

I request you to consider the following points for discussion: 1) Fig 3 of draft-ashwood-nvo3-oam-requirements provides the context for OA= M layering in NVO3. Though, an individual draft at the moment, I submit tha= t we consider this for providing more context to the discussion here.=20 2) Per my understanding of your proposal, the intent is to use BFD for OAM = at the NV edge layer. Please let me know if this understanding is incorrect= . 3) The clarifications requested earlier this thread concern about the inner= IP address (SIP in particular) of the BFD packet . Would they be used from= the overlay IP address space (belonging to the tenant). If this is the cas= e, what would the difference between a BFD session using the tenant IP (at = the NV edge), a particular VNI, and that of a service layer OAM session tha= t can be run using single-hop BFD (RFC 5880).=20 In other words, how can the OAM (BFD in this case) operating at the NV Edge= layer operate without using IP from the Tenant layer if the packet is requ= ired to be VxLAN encapsulated?

It is not clear if this draft is addressing both VM to VM and VTEP to V= TEP verification through BFD. I assume it is both. Draft is applicable only for VTEP to VTEP, for VM to VM (if VM is L3 aware)= BFD as per RFC 5880/5881 should work as it is. VM's will not be aware of a= ny tunnel. Draft talks about tunnel verification which terminates at VTEP's= . >2. If the VMs are Layer 2 only, then what is the inner IP address=20 >(especially source IP)? I understand that outer IP is going to carry the V= TEPs addresses. As mentioned in the draft it would be outgoing interface IP sending VTEP.=20 >3. Why is the inner IP destination address 127/8 or 0:0:0:0:0:FFFF:7F00/10= 4? I understand that it is to avoid the packet being routed but, how can an= IP packet addressed to a particular VTEP be consumed by any other node in = the network and then route the inner >payload? The same argument holds true for MPLS as well right? The motivation for usi= ng the address range 127/8 is the same as described in Section 2.1 of RFC43= 79. >4. The service node's use case is not very clear. Mat be you can add a lit= tle bit of details here. Yes, we can do that.=20 >5. I understand that VTEP knows that the packet is to be terminated at the= VTEP based on TTL being 1. What about the case of VM to VM BFD? What shoul= d be the TTL value here? =A0 Is it 255 or something different? It is hardco= ded to "1" in the draft. VM's will use normal Async BFD so will use TTL 255.=20 >6. Since we are using a destination UDP port of 3784, shouldn't the TTL=20 >be 255 to be consistent with the RFC 5880? Section 7 of RFC 5884 also mentions use of IP TTL set to 1 whereas UDP port= number set to 3784.=20 Thanks Santosh P K =20 From: "Vengada Prasad Govindan (venggovi)" Date: Wednesday, 6 May 2015 9:39 am To: Santosh P K , "rtg-bfd@ietf.org" Subject: RE: New Version Notification for draft-spallagatti-bfd-vxlan-00.tx= t Hello Santosh/ Authors, Thanks for sharing the document, please find a few thoughts below. 1. The current document talks about both BFD and S-BFD - would it be benefi= cial to make separate documents for BFD and SBFD to maintain consistency wi= th the current set of documents. 2. Motivation: It would be nice to state the requirements or motivation tha= t this draft addresses, i.e. what problems does this draft address that can= not be solved using the existing BFD/ SBFD protocol treating the VxLAN as a= tunnel/ underlay transport transparent to BFD. I would submit that BFD ove= r VxLAN not be treated along the same lines of BFD over MPLS or BFD for PW = (VCCV) given the differences in the nature of the transport between MPLS an= d VxLAN. 3. Inner Ethernet header: The document does not address the contents of the= Inner Ethernet header (present after the VxLAN header). This needs to be s= pecified. 4. Destination IP: The document mandates that this needs to be 127/8. What = disadvantages do you observe if the DIP were to be the IP of the destinatio= n VTEP? When using 127/8 as the DIP. one problem is that there is no indica= tion of the intended DIP of the BFD session by using 127/8. What if the nod= e at which the VxLAN tunnel is (prematurely) terminated happens to support = BFD? It may be better to use the IP address of the Destination VTEP as the = DIP. 5. Inner TTL: For the same reasons discussed in (2), why does the document = mandate this to be set to 1? 6. It may be beneficial to run a spell-checker to fix typos in the document= . I request the authors/ WG to comment on the above aspects.

I'll try not to repeat points they already br= ought up. Please find my notes below: * Introduction: o you reference RFC 5880 but don't specify which of defined in BFD ba= se document modes are in scope of this work. I assume that, like in RFC 588= 4, it is only Asynchronous mode and Section 7 excludes Echo BFD but Demand = mode not mentioned. Making more explicit statement would be helpful. * section 2: o I think that these three cases hardly apply to the proposed solutio= n. In particular, BFD may very coarsely localize path failure as we should = remember that path and remote peer failure are undistinguishable. Thus fail= ure detected at one VM, with Tunnel BFD session operational, cannot be inte= rpreted as peer VM failure. * section 3: o what ensures that reverse direction of the BFD session between IP1 = (ingress) and IP2 (egress) , i.e. egress transmits BFD control packets towa= rd the ingress, uses the same tunnel traversed by BFD control packets sent = from ingress toward the egress? Perhaps use of BFD Reverse Path TLV and BFD= Discriminator TLV may be one solution? o Perhaps this section could be the right place to discuss and define= behavior of the egress in terms of its role in BFD session: * packet encapsulation; * failure reporting; * path selection (discussed above). o And the issues of the encapsulation, reverse path selection are rel= evant for S-BFD scenario as well (I think that Prasad's suggestion to split= into two documents, BFD and S-BFD, is quite reasonable). * section 6.1: o considering 5884clarification work, can multiple BFD session operat= e between IP1 and IP2 over the same tunnel?

Hi Santosh, Authors, et. al,
what a great discussion of very interesting work, many thanks to Prasa= d, Mallik and, of course, Santosh. I'll try not to repeat points they alrea= dy brought up. Please find my notes below:
  • Introduction:
  • you reference RFC 5880 but don’t specify which of defined in BFD = base document modes are in scope of this work. I assume that, like in RFC 5= 884, it is only Asynchronous mode and Section 7 excludes Echo BFD but Deman= d mode not mentioned. Making more explicit statement would be helpful.
  • section 2:
  • I think that these three cases hardly apply to the proposed solution. I= n particular, BFD may very coarsely localize path failure as we should reme= mber that path and remote peer failure are undistinguishable. Thus failure = detected at one VM, with Tunnel BFD session operational, cannot be interpreted as peer VM failure.
    • section 3:
    • what ensures that reverse direction of the BFD session between IP1 (ing= ress) and IP2 (egress) , i.e. egress transmits BFD control packets toward t= he ingress, uses the same tunnel traversed by BFD control packets sent from= ingress toward the egress?

    • Perhaps this section could be the right place to discuss and define= behavior of the egress in terms of its role in BFD session:
    • packet encapsulation;
    • failure reporting;
    • path selection= (discussed above).
    • And the issues of the encapsulation, reverse path selection are relevan= t for S-BFD scenario as well (I think that Prasad’s suggestion to spl= it into two documents, BFD and S-BFD, is quite reasonable).
    • section 6.1:

The current document talks about both BFD and S-BFD - would it be benefi= cial to make separate documents for BFD and SBFD to maintain consistency wi= th the current set of documents. 2. Motivation: It would be nice to state the requirements or motivation tha= t this draft addresses, i.e. what problems does this draft address that can= not be solved using the existing BFD/ SBFD protocol treating the VxLAN as a= tunnel/ underlay transport transparent to BFD. I would submit that BFD ove= r VxLAN not be treated along the same lines of BFD over MPLS or BFD for PW = (VCCV) given the differences in the nature of the transport between MPLS an= d VxLAN. 3. Inner Ethernet header: The document does not address the contents of the= Inner Ethernet header (present after the VxLAN header). This needs to be s= pecified. 4. Destination IP: The document mandates that this needs to be 127/8. What = disadvantages do you observe if the DIP were to be the IP of the destinatio= n VTEP? When using 127/8 as the DIP. one problem is that there is no indica= tion of the intended DIP of the BFD session by using 127/8. What if the nod= e at which the VxLAN tunnel is (prematurely) terminated happens to support = BFD? It may be better to use the IP address of the Destination VTEP as the = DIP. 5. Inner TTL: For the same reasons discussed in (2), why does the document = mandate this to be set to 1? 6. It may be beneficial to run a spell-checker to fix typos in the document= . I request the authors/ WG to comment on the above aspects.

    Hi Santosh, Authors, et. al,

    what a great discussion of very interesting work, m= any thanks to Prasad, Mallik and, of course, Santosh. I'll try not to repea= t points they already brought up. Please find my notes below:

    ·         Introduction:

    ·         you reference RFC 5880 but don’t spec= ify which of defined in BFD base document modes are in scope of this work. = I assume that, like in RFC 5884, it is only Asynchronous mode and Section 7 excludes Echo BFD but Demand mode not mentioned. Making= more explicit statement would be helpful.

    ·         section 2:

In particular, BFD may very coarsely localize pa= th failure as we should remember that path and remote peer failure are undistinguishable. Thus failure detected at one VM= , with Tunnel BFD session operational, cannot be interpreted as peer VM fai= lure.

    ·         section 3:

    ·         what ensures that reverse direction of the = BFD session between IP1 (ingress) and IP2 (egress) , i.e. egress transmits = BFD control packets toward the ingress, uses the same tunnel traversed by BFD control packets sent from ingress toward = the egress? Perhaps use of BFD Reverse Path TLV and BFD Discriminator TLV m= ay be one solution?

    ·         Perhaps this section could be the right pla= ce to discuss and define behavior of the egress in terms of its role in BFD= session:

    ·         packet encapsulation;

    ·         failure reporting;

    ·         path selection (discussed above).

    ·         And the issues of the encapsulation, revers= e path selection are relevant for S-BFD scenario as well (I think that Pras= ad’s suggestion to split into two documents, BFD and S-BFD, is quite reasonable).

    ·         section 6.1:

    ·         considering 5884clarification work, can mul= tiple BFD session operate between IP1 and IP2 over the same tunnel?

            Greg

    The same argument holds true for MPLS as well right= ? The motivation for using the address range 127/8 is the same as described= in Section 2.1 of RFC4379.

    Yes, we can do that.

    Hello Santosh/ Authors,

    Thanks for sharing the document, please find a few = thoughts below.

    1. The current document talks about both BFD and S-= BFD - would it be beneficial to make separate documents for BFD and SBFD to= maintain consistency with the current set of documents.

    2. Motivation: It would be nice to state the requir= ements or motivation that this draft addresses, i.e. what problems does thi= s draft address that cannot be solved using the existing BFD/ SBFD protocol treating the VxLAN as a tunnel/ underlay trans= port transparent to BFD. I would submit that BFD over VxLAN not be treated = along the same lines of BFD over MPLS or BFD for PW (VCCV) given the differ= ences in the nature of the transport between MPLS and VxLAN.

    3. Inner Ethernet header: The document does not add= ress the contents of the Inner Ethernet header (present after the VxLAN hea= der). This needs to be specified.

    4. Destination IP: The document mandates that this = needs to be 127/8. What disadvantages do you observe if the DIP were to be = the IP of the destination VTEP? When using 127/8 as the DIP. one problem is that there is no indication of the intended DIP= of the BFD session by using 127/8. What if the node at which the VxLAN tun= nel is (prematurely) terminated happens to support BFD? It may be better to= use the IP address of the Destination VTEP as the DIP.

    5. Inner TTL: For the same reasons discussed in (2)= , why does the document mandate this to be set to 1?

    6. It may be beneficial to run a spell-checker to f= ix typos in the document.

    I request the authors/ WG to comment on the above a= spects.

    Thanks

    Prasad

You bring up a valid point, that needs cl= arification. Even without multiple BFD sessions on the if the eg= ress were to inform about a BFD session going to DOWN (potentially using th= e diag code 0x4 - Neighbor Signalled Down), the YourDisc field needs to be = non-zero, so the ingress can demux the packet to the correct session. With = multiple sessions per FEC, LSP, this becomes absolutely needed, as you rema= rk below. Could we consider adding the following statement: The egress MUST use the discriminators exchanged when the session was broug= ht to indicate a session DOWN back to the ingress. The egress SHOULD reset = this to zero after transmitting detectMult number of packets. Please suggest your thoughts on making the above text better. Thanks Prasad Copying the list for their inputs as well. -----Original Message----- From: Santosh P K [mailto:santoshpk@juniper.net]=20 Sent: Thursday, May 14, 2015 7:44 PM To: draft-ietf-bfd-rfc5884-clarifications@tools.ietf.org Cc: Jeffrey Haas; Nobo Akiya Subject: RE: Working Group Last Call for draft-ietf-bfd-rfc5884-clarificati= ons Hello Authors, Sorry for being so late in the game. I had few points which are not cl= ear from draft.=20 As per RFC 5880 section 6.8.1 it says that when BFD session goes down due t= o control timer expiry then remote discr MUST be set to 0.=20 " bfd.RemoteDiscr The remote discriminator for this BFD session. This is the discriminator chosen by the remote system, and is totally opaque to the local system. This MUST be initialized to zero. If a period of a Detection Time passes without the receipt of a valid, authenticated BFD packet from the remote system, this variable MUST be set to zero." As per RFC 5884 it says that all the demux MUST happen with remote Discrimi= nator and also it talks about Discr not changing only when session is UP. Section 7: Note that once the BFD session for the MPLS LSP is UP, either end of the BFD session MUST NOT change the source IP address and the local discriminator values of the BFD Control packets it generates, unless it first brings down the session. As per clarification draft " draft-ietf-bfd-rfc5884-clarifications" sectio= n 2.4 iterates the same statement.=20 Section 2.4: The discriminators of a BFD session established over an MPLS LSP cannot be changed when it is in UP state. Problem: Now for example if we have multiple LSP's with the same FEC then at egress= it might be sending packet to same designation address. In this case if on= e of the BFD session goes down on egress then it would send BFD packet with= down state with 0 discr. Seeing this ingress would try to demux with IFL a= nd source address on the packet, this will lead to multiple sessions. I thi= nk this needs to be clarified as well. I am not sure if this point is already covered or not. Do you think it is w= orth clarifying this point? I think it plays very important role in bringin= g down the BFD session in MPLS environment. Any thoughts?=20 Thanks Santosh P K=20 > -----Original Message----- > From: Rtg-bfd [mailto:rtg-bfd-bounces@ietf.org] On Behalf Of Jeffrey=20 > Haas > Sent: Tuesday, May 05, 2015 1:28 AM > To: rtg-bfd@ietf.org > Cc: mpls@ietf.org > Subject: Working Group Last Call for=20 > draft-ietf-bfd-rfc5884-clarifications >=20 > The BFD mailing list has been quiet since shortly after IETF 92.

If this is the cas= e, what would the difference between a BFD session using the tenant IP (at = the NV edge), a particular VNI, and that of a service layer OAM session tha= t can be run using single-hop BFD (RFC 5880).=20 In other words, how can the OAM (BFD in this case) operating at the NV Edge= layer operate without using IP from the Tenant layer if the packet is requ= ired to be VxLAN encapsulated?

It is not clear if this draft is addressing both VM to VM and VTEP to V= TEP verification through BFD. I assume it is both. =A0 Draft is applicable only for VTEP to VTEP, for VM to VM (if VM is L3 aware)= BFD as per RFC 5880/5881 should work as it is. VM's will not be aware of a= ny tunnel. Draft talks about tunnel verification which terminates at VTEP's= . =A0 >2. If the VMs are Layer 2 only, then what is the inner IP address=20 >(especially source IP)? I understand that outer IP is going to carry the V= TEPs addresses. =A0 As mentioned in the draft it would be outgoing interface IP sending VTEP.=20 =A0 >3. Why is the inner IP destination address 127/8 or 0:0:0:0:0:FFFF:7F00/10= 4? I understand that it is to avoid the packet being routed but, how can an= IP packet addressed to a particular VTEP be consumed by any other node in = the network and then route the inner >payload? =A0 The same argument holds true for MPLS as well right? The motivation for usi= ng the address range 127/8 is the same as described in Section 2.1 of RFC43= 79. =A0 >4. The service node's use case is not very clear. Mat be you can add a lit= tle bit of details here. =A0 Yes, we can do that.=20 =A0 >5. I understand that VTEP knows that the packet is to be terminated at the= VTEP based on TTL being 1. What about the case of VM to VM BFD? What shoul= d be the TTL value here? =A0 Is it 255 or something different? It is hardco= ded to "1" in the draft. =A0 VM's will use normal Async BFD so will use TTL 255.=20 =A0 >6. Since we are using a destination UDP port of 3784, shouldn't the TTL=20 >be 255 to be consistent with the RFC 5880? =A0 Section 7 of RFC 5884 also mentions use of IP TTL set to 1 whereas UDP port= number set to 3784.=20 =A0 =A0 Thanks Santosh P K =A0 =A0 =A0 From: "Vengada Prasad Govindan (venggovi)" Date: Wednesday, 6 May 2015 9:39 am To: Santosh P K , "rtg-bfd@ietf.org" Subject: RE: New Version Notification for draft-spallagatti-bfd-vxlan-00.tx= t =A0 Hello Santosh/ Authors, Thanks for sharing the document, please find a few thoughts below. 1. The current document talks about both BFD and S-BFD - would it be benefi= cial to make separate documents for BFD and SBFD to maintain consistency wi= th the current set of documents. 2. Motivation: It would be nice to state the requirements or motivation tha= t this draft addresses, i.e. what problems does this draft address that can= not be solved using the existing BFD/ SBFD protocol treating the VxLAN as a= tunnel/ underlay transport transparent to BFD. I would submit that BFD ove= r VxLAN not be treated along the same lines of BFD over MPLS or BFD for PW = (VCCV) given the differences in the nature of the transport between MPLS an= d VxLAN. 3. Inner Ethernet header: The document does not address the contents of the= Inner Ethernet header (present after the VxLAN header). This needs to be s= pecified. 4. Destination IP: The document mandates that this needs to be 127/8. What = disadvantages do you observe if the DIP were to be the IP of the destinatio= n VTEP? When using 127/8 as the DIP. one problem is that there is no indica= tion of the intended DIP of the BFD session by using 127/8. What if the nod= e at which the VxLAN tunnel is (prematurely) terminated happens to support = BFD? It may be better to use the IP address of the Destination VTEP as the = DIP. 5. Inner TTL: For the same reasons discussed in (2), why does the document = mandate this to be set to 1? 6. It may be beneficial to run a spell-checker to fix typos in the document= . I request the authors/ WG to comment on the above aspects.
