Abstract

Various example embodiments for supporting multicast in communication systems are presented. In at least some example embodiments, supporting multicast in communication systems may include supporting use of multicast domain information of a penultimate hop router of the multicast domain by an egress leaf router associated with the multicast domain for multicast service signaling to a root router of the multicast domain. In at least some example embodiments, in which the multicast domain is based on Bit Index Explicit Replication (BIER), supporting multicast in communication systems may include supporting use of BIER domain information (e.g., a BIER Forwarding Router Identifier (BFR-ID) or the like) of a PH BIER router by an egress leaf router associated with the BIER domain for multicast service signaling to a root BIER router of the BIER domain.
