Edge router based on the virtual private LAN service

摘要

The present invention is a method of processing method and a data packet for processing messages at the edge routers of the communications network based on VPLS, and shows an edge router for performing the method of their corresponding. In an embodiment of the method according to the invention, the edge router is interconnected with a second edge router, to provide access to the communication network for the two edge routers first apparatus and the second apparatus, respectively, the method, the wherein the MAC address of the first device as an L2 source address, when a message from a first device including the IP address of the second device as a L3 destination address is received, the virtual MAC of the first device L2 source address of the message and by converting the address, the message having the virtual MAC address of the first device, and a thing to be transmitted to the second edge router in accordance with the IP address of the second device, the virtual MAC address of the first device, the edge including information PEID identifying a router, and information VMID identifying the first device, and information VIDCA for avoidance of collision when the collision may occur in identifying the first device.
