<p>An L2 virtual private network (L2VPN) interworking method is provided. The method comprises: receiving, by a provider edge (PE), a message from a local customer edge (CE), stripping off a link layer header of the message, performing pseudowire (PW) encapsulation on the message, and sending the encapsulated message onto a PW, wherein the PW encapsulation header includes a protocol type field and the value of the protocol field is identical to the protocol type indicated by the value of the protocol type field in the original link layer header of the message. The method further comprises: receiving, by a PE, a message from a remote CE over a PW, stripping off a PW encapsulation header of the message, encapsulating a destination link layer header in the message, and sending the message to a local CE, wherein the value of the protocol type field in the destination link layer header is identical to the protocol type indicated by the value of the protocol type field in the PW encapsulation header.</p> |
