RFC 8665: OSPF Extensions for Segment Routing
Recent RFCs 2019-12-07
Summary:
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 OSPFv2 extensions required for Segment
Routing.
