description Functionality for creating a bit routing table for use in a bit-indexed explicit replication ("BIER") environment in disclosed herein. In one embodiment, this functionality includes receiving information from a host, and determining whether the information comprises a MAC address that is a bit-indexed explicit replication ("BIER") MAC address. In response to determining that the information comprises a BIER MAC address, this functionality creates an entry corresponding to the MAC address in a bit routing table. This functionality also analyzes the information to determine a bit position that is associated with the host, and also determines a port via which the host is reachable. The functionality updates the bit routing table by storing information identifying the bit position and the port in the entry, such that the bit position and the port both correspond to the MAC address. This functionality can be used to route packets in a BIER environment.
