Abstract
Various systems and methods for performing bit indexed explicit replication (BIER). For example, one method involves receiving a membership message that was generated by an egress router, where the membership message comprises information identifying a multicast group, and information identifying a plurality of egress routers. The method identifies at least one bit position in the membership message that is associated with the first egress router, where at least one bit position of the plurality of bit positions is associated with the first egress router. The method also records membership of the first egress router in the multicast group, where the membership is recorded in a bit of a group membership table, and the bit corresponds to the bit position identified in the membership message.
