Abstract
A packet forwarding method. The method includes: a first node configures a first identifier of a first VPN and a first IPv6 address on a control plane. The first node sends a first indication message to a second node, where the first indication message carries the first identifier and the first IPv6 address. The second node first determines, based on locally configured information about the first VPN and the first identifier in the first indication message, a second identifier that is of the second node and that satisfies a preset correspondence with the first identifier, and then establishes a correspondence between the first IPv6 address and the second identifier. The first node encapsulates, on a forwarding plane based on the first IPv6 address, a multicast data packet belonging to the first VPN, to obtain a to-be-forwarded BIER packet and sends the to-be-forwarded BIER packet.
