RFC 8666 PDF | OSPFv3 Extensions for Segment Routing

Abstract

Segment Routing (SR) allows a flexible definition of end-to-end paths within IGP topologies by encoding paths as sequences of topological subpaths called "segments". These segments are advertised by the link-state routing protocols (IS-IS and OSPF).

This document describes the OSPFv3 extensions required for Segment Routing with the MPLS data plane.
