Abstract:
Segment Routing leverages source routing. A node steers a packet
through a controlled set of instructions, called segments, by
prepending the packet with an SR header. A segment can represent any
instruction, topological or service-based. SR allows to enforce a
flow through any topological path and service chain while maintaining
per-flow state only at the ingress node of the SR domain.
IGP protocols have been extended to advertise the segments. Because
of IGP's propagation scope limitation, it is not suited for IGP to
signal paths that span across AS borders. This document introduces
extensions of PCEP-LS to solve the problem without the similar
limitation.
