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.
