Edge router virtual private local area network services

The present invention provides a method of processing a message in the edge router VPLS-based communication network, a method of processing data packets, and performing an edge router corresponding method. In an embodiment of the method according to the present invention, the edge router and the edge router is connected to a second, respectively, and first and second devices providing access to a communication network, the method comprising: receiving from a first device to comprise a first MAC address of the device as a layer two source address, IP address of the second device as a destination address of a layer three message, converts the layer two source address of the message to the first device in a virtual MAC address, and according to a second device the IP address of the message with a virtual MAC address of the first device to the second edge router, wherein the virtual MAC address of the first device contains information identifying the edge router PEID, VMID first device identification information, and when the identification of a device used to avoid conflicts when information VIDCA information conflict.
