Abstract

The invention provides a method, device and network equipment for generating a multilink transparent transmission interconnection forwarding table. The method comprises the following steps of: receiving, by a first routing switch in a first network, an LSP (Label Switching Path) message sent by a second routing switch connected with the first routing switch in the second network; respectively comparing Nicknames and system identifiers corresponding to the Nicknames in the LSP message with that in a local link state database so as to judge whether conflicting Nicknames exist; and updating the local link state database according to the LSP message when the judging result shows that the conflicting Nicknames exist, and generating a TRILL (Transparent Interconnection of Lots of Links) forwarding table according to the updated local link state database and the conflicting Nicknames. When the technical scheme provided by the invention is adopted, the problem of data stream losses caused by the wrong forwarding of the data stream due to the conflict of the Nicknames is solved, and the success rate of the forwarding of the data stream is improved.

Description

Technical field [0001] The present invention relates to the field of data communication, in particular to a method, device and network equipment for generating a multi-link transparent transmission interconnection forwarding table. Background technique [0002] In the Transparent Interconnection of Lots of Link (TRILL) network, the switch running the TRILL protocol has both the Layer 2 forwarding function and the Layer 3 routing function, and is usually called the Route Bridge (Route Bridge; Referred to as: RBridge). The data flow in the TRILL network is forwarded by searching the TRILL forwarding table according to the Nickname of RBridge (the TRILL forwarding table includes two contents Nickname and the media access control (Media Access Control; referred to as: MAC) address of the next hop routing switch), and find The next hop corresponding to the destination RBridge is forwarded. [0003] figure 1 It is a schematic diagram of the structure of a TRILL network in the prior art...
