摘要： The present disclosure generally discloses a multicast capability configured to support multicast that is based on use of Bit Indexed Explicit Replication (BIER). The multicast capability may be configured to support deployment of BIER into a network in a manner that continues to support use of Protocol Independent Multicast (PIM) for multicast control within the network. The multicast capability may be configured to support deployment of BIER, into a network including an Interior Gateway Protocol (IGP) area, using a BIER domain that is commensurate with the IGP area or that is only a portion of the IGP area. The multicast capability may be configured to support deployment of BIER into a network in a manner supporting stitching of traditional PIM access networks via a BIER core network.

摘要： A border router includes at least one processor and at least one memory including computer program code. The at least one memory and the computer program code is configured to, with the at least one processor, cause the border router to: identify, in response to receiving a label mapping message from a network node, a backup border router as a hop in a backup path between a leaf node and a root node in a multicast network including an autonomous system, the label mapping message including a type-length-value; determine whether the backup border router is an originating border router having generated the label mapping message based on the type-length-value; and suppress mapping of the hop in the backup path in response to determining that the backup border router is the originating border router.
