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. |
