Abstract 

   SR P2MP policies are set of policies that enable architecture for
   P2MP service delivery.

   A P2MP policy consists of candidate paths that connects the Root of
   the Tree to a set of Leaves. The P2MP policy is composed of
   replication segments. A replication segment is a forwarding
   instruction for a candidate path which is downloaded to the Root,
   transit nodes and the leaves. 

   This document defines a YANG data model for SR P2MP Policy
   Configuration and operation.

Internet-Draft     YANG Data Model for P2MP SR Policy   October 30, 2019

   The draft [draft-voyer-spring-sr-p2mp-policy] defines a variant of
   the SR Policy [I-D.  ietf-spring-segment-routing-policy] for
   constructing a P2MP segment to support multicast service delivery.

   A Point-to-Multipoint (P2MP) Policy contains a set of candidate paths
   and identifies a Root node and a set of Leaf nodes in a Segment
   Routing Domain. The draft also defines a Replication segment, which
