OSPFv3 Extensions for Segment Routing
RFC 8666, “OSPFv3 Extensions for Segment Routing”, is a Proposed Standard document published in December 2019 by P. Psenak, S. Previdi. The canonical text is published by the RFC Editor.
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.
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.
