RFC 9514: Border Gateway Protocol - Link State (BGP-LS) Extensions for Segment Routing over IPv6 (SRv6)
Recent RFCs 2023-12-06
Summary:
Segment Routing over IPv6 (SRv6) allows for a flexible definition of
end-to-end paths within various topologies by encoding paths as
sequences of topological or functional sub-paths called "segments".
These segments are advertised by various protocols such as BGP,
IS-IS, and OSPFv3.
This document defines extensions to BGP - Link State (BGP-LS) to
advertise SRv6 segments along with their behaviors and other
attributes via BGP. The BGP-LS address-family solution for SRv6
described in this document is similar to BGP-LS for SR for the MPLS
data plane, which is defined in RFC 9085.
