Patent abstract
Embodiments of the present invention provide a VPLS fast rerouting method and device. The method includes: generating, by a remote PE, a backup forwarding entry; and when a designated forwarder or a designated forwarder pseudo wire in a multihoming protection group fails, or the designated forwarder is switched in the multihoming protection group, forwarding, by the remote PE, a data packet according to the backup forwarding entry, thereby avoiding broadcasting the data packet to all remote PEs that belong to the same VPLS instance, and further reducing a waste of bandwidth resources in a backbone network and processing resources of the PE.
