Segment Routing (SR) allows for a flexible definition of end-to-end
paths by encoding paths as sequences of topological subpaths, called
"segments". These segments are advertised by routing protocols, e.g.,
by the link-state routing protocols (IS-IS, OSPFv2, and OSPFv3)
within IGP topologies.

This document defines extensions to the Border Gateway Protocol -
Link State (BGP-LS) address family in order to carry SR information
via BGP.

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 
standardization state and status of this protocol.  Distribution of this 
memo is unlimited.
