Abstract
A bit index explicit replication (BIER) forwarding entry construction method is provided. The method includes receiving, by a second network device, a first message sent by a first network device, where the first message includes a host routing prefix of the first network device, first BIER information, and second BIER information. The first BIER information includes a bit index forwarding table identifier (BIFT ID) of the first network device, the second BIER information includes a bit forwarding router identifier (BFR ID) of at least one bit forwarding router (BFR) in a first area. The second network device constructs a BIER forwarding entry based on the first BIER information, the second BIER information, and the host routing prefix.
