    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.

    Abstract: A route generation method, performed in an SRv6 network and including: receiving, by a first network device, a first notification packet from a second network device; where the first notification packet includes a network slice identifier, the first notification packet indicates an association relationship between information of the network slice identifier and an IPv6 address prefix of the second network device, and the network slice identifier is used to identify one network slice; and generating, by the first network device, a route forwarding entry for the IPv6 address prefix of the second network device based on an association relationship between the network slice identifier and the IPv6 address prefix of the second network device. This helps implement a network slice and resource isolation in the SRv6.
