A node steers a packet through a controlled set of instructions,
called segments, by prepending the packet with a list of segment
identifiers (SIDs).  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 Border Gateway Protocol -
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.

This document is a product of the Inter-Domain Routing Working Group of the IETF.

This is now a Proposed Standard.

STANDARDS TRACK: This document specifies an Internet Standards Track
protocol for the Internet community, and requests discussion and suggestions
for improvements.  Please refer to the current edition of the Official
Internet Protocol Standards (https://www.rfc-editor.org/standards) for the
