Border Gateway Protocol - Link State Extensions for Segment Routing over IPv6
RFC 9514, “Border Gateway Protocol - Link State Extensions for Segment Routing over IPv6”, is a Proposed Standard document published in December 2023 by G. Dawra, C. Filsfils, K. Talaulikar, M. Chen, D. Bernier, B. Decraene. The canonical text is published by the RFC Editor.
Abstract
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.
What “Proposed Standard” means
An entry-level standards-track specification: stable, peer-reviewed and a solid basis for implementation, though it may still evolve before becoming an Internet Standard.
