   Segment Routing (SR) architecture allows a node to steer a packet
   flow through any topological path and service chain by leveraging
   source routing.  The ingress node prepends a SR header to a packet
   containing a set of "segments".  Each segment represents a
   topological or a service-based instruction.  Per-flow state is
   maintained only at the ingress node of the SR domain.

   This document describes the BGP extension for announcing BGP Prefix
   Segment Identifier (BGP Prefix SID) information.
