Abstract


Segment Routing (SR) 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 segments allow
steering a flow through any topological path and service chain while
maintaining per-flow state only at the ingress node of the SR domain.

This document describes an extension to BGP Link State (BGP-LS) for
advertisement of BGP Peering Segments along with their BGP peering
node information so that efficient BGP Egress Peer Engineering (EPE)
policies and strategies can be computed based on Segment Routing.
