US 2019/0097944 A1 · MULTICAST BASED ON BIT INDEXED EXPLICIT REPLICATION

Abstract

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.

Claims22

Dependent claims

An apparatus, comprising:

a processor and a memory communicatively connected to the processor, the processor configured to:
receive, by a Bit Indexed Explicit Replication (BIER) border router of a BIER domain, a control message associated with a multicast group of a multicast source, wherein the BIER domain is an Interior Gateway Protocol (IGP) area;
and
determine, by the BIER border router, a border router which leaked a route to the multicast source into the BIER domain.
