Hi Sue, I was referring to https://datatracker.ietf.org/doc/draft-ketant-idr-bgp-ls-bgp-only-fabric/ Seeing the interest in the WG to progress BGP-LS advertisements in BGP-only networks, I would request for the WG to consider adoption of the above draft. I believe the problem statement of the

Jeff: I agree your BGP-LS only deployment in the MSD document were not well defined. Starting a new set of work to define BGP-LS use in BGP-only is important. If this document start the process to refine how BGP-only works, this will help defined this usage. I stand by the

Les: As you know, part of the chair’s duty is to determine if the authors have missed mentioning something in their draft proposal. My questions were about the BGP-only features since it seemed obvious to me after working with the draft-ietf-idr-tunnel-encaps as a shepherd. BGP has had

Zhibo – It is good of you to “keep me honest” as regards my past comments. In reviewing the relevant material, the best I can say as regards my comments from 2 years ago is that they were made with insufficient diligence. Apologies for any resulting confusion.

Hi Les, Inter-AS E2E sr-policy scenario also need this. The inter-as link info will be collected by BGP EPE. The MTU is link’s attribute, so we need independent attribute TLV for all protools’ link NLRI. Regards, Haibo From: Idr [mailto:idr-boun...@ietf.org] On Behalf Of Jeff

Hi Zhibo, I agree with everything that was discussed and concluded on that thread which you referred to. It was about re-using existing sub-TLV for link MTU defined for Trill in ISIS. We are still saying the same thing! There is still the work required for the base ISIS procedures to be

To add to Les’s point of BGP only scenario, during MSD IESG reviews, BGP-LS only deployment was found not well characterized and had been removed from the draft. It will require much better discussion to have it included. Regards, Jeff > On Nov 13, 2020, at 15:57, Les Ginsberg (ginsberg)

The points which Ketan has made regarding the use of MTU advertisements defined in RFC 7176 are very valid. Indeed, the contents of the sub-TLV defined in https://www.rfc-editor.org/rfc/rfc7176.html#section-2.4 depend upon the TRILL specific MTU-probe/MTU-ack procedures defined in

Hi Authors, I believe this work is useful and should be taken up. It has value in providing the link MTU as part of the topology information via BGP-LS. However, as pointed out by others on this thread, the draft should remain scoped to just that – i.e. providing link MTU information. The
