Embodiments of the present invention provide a virtual private local area network service VPLS fast rerouting method and device. The method includes: generating, by a remote provider edge device PE, a backup forwarding entry; and when a designated forwarder or a designated forwarder pseudo wire in a mltihoming 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. |
