Abstract: A destination node device starts a timer when the destination node device determines that a network topology changes; before the timer expires, the destination node device forwards the BIER packet by using an old forwarding table and establishes a new forwarding table, where the old forwarding table is a forwarding table used by the destination node device before the network topology changes, the new forwarding table is a forwarding table established by the destination node device based on the changed network topology; and after the timer expires, the destination node device switches the old forwarding table to the new forwarding table, and forwards the BIER packet according to the new forwarding table.

Abstract: A method for neighbor discovery including: transmitting a neighbor detection message according to a neighbor VLAN information table, where the neighbor VLAN information table includes neighbor VLAN information; receiving a neighbor response message with which a terminal responds; acquiring a MAC address of the terminal according to the neighbor response message. With the method, numerous invalid detections, heavy apparatus load and large CPU resource consumption caused by traversing a public network VLAN and a private network VLAN to conduct neighbor detection decease.
