OSPF Extensions for Segment Routing

Clarence Filsfils, Hannes Gredler, Rob Shakir, Wim Henderickx, Jeff Tantsura

Abstract

Segment Routing (SR) allows 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 draft describes the OSPFv3 extensions required for Segment Routing with MPLS data plane.
