IS-IS Extensions to Support Segment Routing over IPv6 Dataplane
draft-bashandy-isis-srv6-extensions-00
Abstract
Segment Routing (SR) allows for a flexible definition of end-to-end
paths by encoding paths as sequences of topological sub-paths, called
"segments". Segment routing architecture can be implemented over an
MPLS data plane as well as an IPv6 data plane. This draft describes
the IS-IS extensions required to support Segment Routing over an IPv6
data plane.
