Abstract
A multicast forwarding method comprises: establishing, by a network device, BIER multicast forwarding information for joining a target multicast group according to a multicast join packet initiated by a multicast receiver connected to a second edge node in a second AS, the second edge node serving as a BFER in a second BIER domain, the target multicast group being a multicast group to which a multicast source connected to a first edge node in a first AS belongs, and the first edge node serving as a BFIR in a first BIER domain; and modifying a BFR ID of the second edge node carried in the multicast join packet into a first BFR ID, and continuing to send the multicast join packet to the first edge node, wherein the first BFR ID is a BFR ID configured when the network device is deployed as the BFER in the first BIER domain.
