1. A method implemented by a first node in a first bit index explicit replication (BIER) domain, wherein the method comprises:
receiving, from a second node in a second BIER domain, a packet carrying a first identifier of the second BIER domain;
determining, based on the first identifier and according to a locally configured BIER packet sending policy, a BIER packet sending policy corresponding to the first identifier, wherein the BIER packet sending policy comprises path information corresponding to the first identifier, and wherein the path information identifies a path from the first node to the second node;
encapsulating the path information into a BIER packet; and
sending, based on the path information, the BIER packet to the second BIER domain.
