  • Distributing non-unicast routes information in a TRILL network
    Patent number: 9942126
    Abstract: The present invention discloses a method for processing non-unicast routes information in a TRILL network and a corresponding RBridge, wherein the RBridge has a neighbor relation with a plurality of other RBridges in the TRILL network, and the RBridge is the RBridge which computes non-unicast routes information in the neighbor relation, and in the method, the RBridge executes steps of: sending an acknowledgement message to the plurality of other RBridges, wherein the acknowledgement message acknowledges that the RBridge is the RBridge which computes the non-unicast routes information; obtaining a network topology related to the non-unicast routes information in the TRILL network; computing the non-unicast routes information based on the network topology; and distributing the computed non-unicast routes information to the plurality of other RBridges. The method and the corresponding RBridge are capable of reducing consumption of CPU resource of RBridges in the TRILL network.
    Type: Grant
