Technical Summary

This document describes how to support Segment Routing BGP Egress
Peer Engineering over Layer 2 bundle members. It updates RFC 9085 to
allow the L2 Bundle Member Attributes TLV in the BGP-LS Attribute of
the BGP-LS Link NLRI for a BGP peering link. For SR-MPLS, it updates
RFC 9085 and RFC 9086 to allow the PeerAdj SID TLV as a sub-TLV of
the L2 Bundle Member Attributes TLV.

Working Group Summary

Was there anything in the WG process that is worth noting?
For example, was there controversy about particular points
or were there decisions where the consensus was
particularly rough?

No controversy.
This document has strong consensus from authors plus 19 other WG members.

Document Quality

Are there existing implementations of the protocol? Have a
significant number of vendors indicated their plan to
implement the specification? Are there any reviewers that
merit special mention as having done a thorough review,
e.g., one that resulted in important changes or a
conclusion that the document had no substantive issues? If
there was a MIB Doctor, Media Type, or other Expert Review,
what was its course (briefly)? In the case of a Media Type
Review, on what date was the request posted?

Two existing implementations. Details are included in the text (for removal before publication).

Personnel
