Segment Routing (SR) leverages the source-routing paradigm. A node
steers a packet through an ordered list of instructions called
"segments". A segment can represent any instruction, topological or
service based. The ingress node prepends an SR header to a packet
containing a set of segment identifiers (SIDs). Each SID represents a
topological or service-based instruction. Per-flow state is
maintained only on the ingress node of the SR domain. An "SR domain"
is defined as a single administrative domain for global SID
assignment.

This document defines an optional, transitive BGP attribute for
announcing information about BGP Prefix Segment Identifiers (BGP
Prefix-SIDs) and the specification for SR-MPLS SIDs.

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.

This announcement is sent to the IETF-Announce and rfc-dist lists.
