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 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.
The Segment Routing architecture can be directly applied to the MPLS
dataplane with no change on the forwarding plane. It requires minor
extension to the existing link-state routing protocols.
This document outline a BGP-LS extension for exporting BGP egress
point topology information (including its peers, interfaces and
peering ASs) in a way that is exploitable in order to compute
efficient Egress Point Engineering policies and strategies.
