VIRTUAL PRIVATE LAN SERVICE BASED EDGE ROUTER

摘要

In an embodiment, an edge router is interconnected with a second edge router and the two edge routers respectively provide accesses to the communication network for a first device and a second device. The method includes, when a message containing a MAC address of the first device as a L2 source address and an IP address of the second device as a L3 target address from the first device is received, converting the L2 source address of the message into a virtual MAC address of the first device; and sending a message having the virtual MAC address of the first device to the second edge router according to the IP address of the second device. The virtual MAC address of the first device contains information PEID identifying the edge router, information VMID identifying the first device and information VIDCA for, in case that there may be a collision when identifying the first device, collision avoidance.

1. A method for processing messages on an edge router of a virtual private LAN service (VPLS) based communication network, the edge router being interconnected with a second edge router, the edge router and the second edge router respectively providing accesses to the communication network for a first device and a second device, the method comprising:
when a message containing a MAC address of the first device as a L2 source address and an IP address of the second device as a L3 target address from the first device is received, converting the L2 source address of the message into a virtual MAC address of the first device; and sending a message having the virtual MAC address of the first device to the second edge router according to the IP address of the second device, wherein the virtual MAC address of the first device contains information PEID identifying the edge router, information VMID identifying the first device and information VIDCA for, in case that there may be a collision when the first device is identified, collision avoidance.
