Abstract
In a VPLS network, a first PE in a VPN instance sends topology information and a bridging MAC address of the first PE to another PE in the VPN instance, receives and stores topology information and bridging MAC addresses from the another PE. The first PE further generates a CE MAC table in the VPN instance according to the stored topology information and bridging MAC addresses of the another PE; calculates a unicast minimal spanning tree by taking the first PE as a root, generates a unicast MAC table in the VPN instance according to the unicast minimal spanning tree. Each PE further selects one of the PEs in the VPN instance as a root bridge, calculates a broadcast minimal spanning tree by taking the root bridge as a root, and generates a broadcast MAC table in the VPN instance according to the broadcast minimal spanning tree.
