Abstract Abstract
This document defines a new BGP SAFI with a new NLRI in order to This document defines a new BGP SAFI with a new NLRI in order to
advertise a candidate path of a Segment Routing Policy (SR Policy). advertise a candidate path of a Segment Routing Policy (SR Policy).
An SR Policy is a set of candidate paths, each consisting of one or An SR Policy is a set of candidate paths, each consisting of one or
more segment lists. The headend of an SR Policy may learn multiple more segment lists. The headend of an SR Policy may learn multiple
candidate paths for an SR Policy. Candidate paths may be learned via candidate paths for an SR Policy. Candidate paths may be learned via
a number of different mechanisms, e.g., CLI, NetConf, PCEP, or BGP. a number of different mechanisms, e.g., CLI, NetConf, PCEP, or BGP.
