<p>Embodiments of the present invention provide a Virtual Private LAN Service (VPLS) fast rerouting method and device. The method comprises: generating a backup forwarding entry at a remote Provider Edge (PE); and when a designated forwarder or a designated forwarder pseudo wire in a multihomed protection group fails or the designated forwarder is switched over in the multihomed protection group, the remote PE forwarding, according to the backup forwarding entry, a data packet, thereby avoiding that the data packet is broadcast to all remote PEs belonging to the same VPLS instance, and further reducing a waste of backbone network bandwidth resources and PE processing resources.</p> |
