Ballot Text

Technical Summary

   A Segment Routing (SR) Policy is an ordered list of segments (i.e.,
   instructions) that represent a source-routed policy.  An SR Policy
   consists of one or more candidate paths, each consisting of one or
   more segment lists.  A headend may be provisioned with candidate
   paths for an SR Policy via several different mechanisms, e.g., CLI,
   NETCONF, PCEP, or BGP.

   This document specifies how BGP may be used to distribute SR Policy
   candidate paths.  It introduces a BGP SAFI to advertise a candidate
   path of a Segment Routing (SR) Policy and defines sub-TLVs for the
   Tunnel Encapsulation Attribute for signaling information about these
   candidate paths.

   This documents updates RFC9012 with extensions to the Color Extended
   Community to support additional steering modes over SR Policy.
