Abstract: A BIER domain includes a host and a routing device that has a neighbor relationship with the host. The host duplicates a packet and forwards the packet to another host via the routing device. After receiving the packet including a BIER option, the routing device pops up, from the packet, an IPV6 extension header including the BIER option, and then sends the packet to the host. This avoids a case in which the packet received by the host includes the IPV6 extension header including the BIER option, thereby reducing a difficulty of processing the packet by the host and reducing overheads of processing the packet by the host.
