Claim:
1. A method for transmitting a packet in a Virtual Private LAN Service (VPLS) network comprising: sending, by a first Provider Edge (PE) in a VPN instance, topology information and a bridging Media Access Control (MAC) address of the first PE to another PE in said VPN instance; receiving and storing topology information and bridging MAC addresses from the another PE; generating, by the first PE, a Customer Edge (CE) MAC table in the VPN instance according to the stored topology information and the bridging MAC addresses of the another PE; calculating a unicast minimal spanning tree by taking the first PE as a root, generating a unicast MAC table in the VPN instance according to the unicast minimal spanning tree; selecting one of the PEs in the VPN instance as a root bridge; calculating a broadcast minimal spanning tree by taking the root bridge as a root, and generating a broadcast MAC table in the VPN instance according to the broadcast minimal spanning tree.
