Abstract
In an example, a network device may receive a L3VPN packet of which an egress label edge router (LER) is the network device, and acquire an adjacency index of an adjacency entry in an adjacency table according to the destination IP address of the inner IP datagram from the L3VPN packet. The network device may acquire a PW extended index of a PW extended entry in a PW extended table and a private network layer-2 header for the inner IP datagram from an adjacency entry having the adjacency index. By using the private network layer-2 header and a public network label, a private network label and a public network layer-2 header in a PW extended entry having the PW extended index, the network device may encapsulate the inner IP datagram into a L2VPN packet and forward the L2VPN packet through a physical egress interface in the PW extended entry.
