[spring-chair hat off + idr] Hi! I took a quick look at the draft -- it uses existing TLVs to convey the information, which is good. Given that (IIRC) BGP-LS does not limit TLVs' use as sub-TLVs, rfc9085 already contemplates using the Adjacency SID TLV (as a sub-TLV), and rfc9086 already says that additional TLVs can be included to describe a link's characteristics, I find the contents quite obvious. The update proposed in §3.1 is not needed: This document updates [RFC9085] and [RFC9086] to allow the PeerAdj SID TLV to be included as a sub-TLV of the L2 Bundle Member Attributes TLV. [I expected something similar in §3.2 about using the SRv6 End.X SID TLV as a sub-TLV, but that text is not present. It is not needed anyway.] My 2c. Alvaro.

As suggested by IDR WG chair, we request for review and comments in SPRING. Any discussion, suggestion or comment is appreciated. Some information about the draft: Abstract There are deployments where the Layer 3 interface on which a BGP peer session is established is a Layer 2 interface bundle. In order to allow BGP-EPE to control traffic flows on individual member links of the underlying Layer 2 bundle, BGP Peering SIDs need to be allocated to individual bundle member links, and dvertisement of such BGP Peering SIDs in BGP-LS is required. This document describes how to support Segment Routing BGP Egress Peer Engineering over Layer 2 bundle. link https://datatracker.ietf.org/doc/draft-lin-idr-sr-epe-over-l2bundle/ ------------------------------ Best Regards, Zhenqiang Li China Mobile li_zhenqiang@hotmail.com _______________________________________________ spring mailing list -- spring@ietf.org To unsubscribe send an email to spring-leave@ietf.org
