Abstract

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.
