<p>Disclosed is a private network data forwarding method for a layer 3 virtual private network (L3VPN), which comprises: setting a public network tunnel between provider edges (PEs), and setting the correlation between private network data to be transmitted and the set public network tunnel; and after the private network data is transmitted to a local PE from a customer edge (CE), according to the correlation between the private network data and the public network tunnel, the local PE searching for an outer-layer public network label of the private network data, and after conducting inner- and outer-layer encapsulation on the private network data, sending same to an opposite PE through the set public network tunnel. Also disclosed at the same time are a device and system for achieving the method. The method, device and system can be applied to control different private network data to be transmitted in a public network through a set path.</p> |
