IS-IS Extensions for Segment Routing
RFC 8667, “IS-IS Extensions for Segment Routing”, is a Proposed Standard document published in December 2019 by S. Previdi, L. Ginsberg, C. Filsfils, A. Bashandy, H. Gredler, B. Decraene. The canonical text is published by the RFC Editor.
Abstract
Segment Routing (SR) allows for a flexible definition of end-to-end paths within IGP topologies by encoding paths as sequences of topological sub-paths, called "segments". These segments are advertised by the link-state routing protocols (IS-IS and OSPF).
This document describes the IS-IS extensions that need to be introduced for Segment Routing operating on an 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.
