Abstract:

   Segment Routing (SR) allows a node to steer a packet flow along any
   path.  SR Policy is an ordered list of segments (i.e., instructions)
   that represent a source-routed policy.  The packets steered into an
   SR Policy carry an ordered list of segments associated with that SR
   Policy.  An SR Policy can be instantiated SR-MPLS and SRv6 data
   planes.

   In some use cases, an SRv6 Policy's SID list ends with the policy
   endpoint's node SID, and the traffic steered (over policy) already
   ensures that it is taken to the policy endpoint.  In such cases, the
   SID list can be optimized by excluding the endpoint Node SID when
   installing the policy.  This draft specifies procedures to indicate
   whether the endpoint's node SID needs to be included or excluded when
   installing the SRv6 Policy.
