It defines the SR\r\nP2MP Policy construct, candidate paths (CPs) of an SR P2MP Policy,\r\nand the instantiation of the P2MP tree instances (PTIs) of a CP using\r\nReplication segments. Additionally, it describes the required\r\nextensions for a controller to support P2MP path computation and\r\nprovisioning.
