Hi Peter, Thanks for your pointer to RFC 9513. Although in the IANA section of RFC 9513, the L2BM flag of the SRv6 related sub-TLVs is set to Y, the whole document has no mentioning of the use of these sub-TLVs in L2 bundle scenario. This document provides complementary description about the applicability of SRv6 related sub-TLVs for L2 bundle in OSPFv3, following the style in RFC 9356.
That said, as in my previous reply to Les, the major purpose of this draft is to introduce compact encoding of SRv6 SIDs for L2 bundle member links in IS-IS.

For IS-IS, this document proposes new sub-TLVs to achieve compact encoding of SRv6 SIDs of the L2 bundle member links, following the approach used in RFC 8668. For OSPFv3, RFC 9356 only defines the mechanism and encoding for carrying SR-MPLS SIDs, SRv6 is not covered. Although IANA has set the L2BM flag for the SRv6 related sub-TLVs, there is no explicit documentation of their usage for L2 bundle. [RFC9513<https://www.iana.org/go/rfc9513>] is very clear allowing these for L2 links. What are you adding in this draft to it? thanks, Peter Hope this could be discussed and clarified during the LSR session. -Jie -----Original Message----- From: Les Ginsberg (ginsberg) <[email protected]><mailto:[email protected]> Sent: Friday, July 18, 2025 4:56 AM To: [email protected]<mailto:[email protected]>; lsr <[email protected]><mailto:[email protected]> Subject: Review of draft-dong-lsr-l2bundle-srv6-03 Regarding https://datatracker.ietf.org/doc/draft-dong-lsr-l2bundle-srv6/ - this draft has been around for a few years - but I wasn't aware of it - and don't recall it ever being presented - though I may have overlooked it. But as I saw it on the agenda for IETF 123 I took a look at it. The functionality it defines has already been defined. For IS-IS see https://www.rfc-editor.org/rfc/rfc9352.html#name-advertising-srv6-adjacency- Note that the sub-TLV is allowed in TLV 25: https://www.rfc-editor.org/rfc/rfc9352.html#name-srv6-endx-sid-and-srv6-lan- For OSPF the equivalent functionality is defined in https://www.rfc-editor.org/rfc/rfc9356 Therefore there is no need for draft-dong-lsr-l2bundle-srv6. I would suggest that it be dropped from the agenda. Apologies to the draft authors for not spotting this sooner.
