Abstract

The present invention discloses a method and device for multi-homing access to the shortest path bridging network, wherein the method includes: receiving an LSP message flooded by an edge node including a cross-node LAG port in the network, wherein the above LSP message Carry B-MAC, BaseVID and the entry system number of the above-mentioned edge node; generate the B-VID corresponding to the above-mentioned edge node according to the above-mentioned BaseVID and the above-mentioned entry system number; establish a forwarding table according to the above-mentioned B-MAC and the above-mentioned B-VID. The invention solves the technical problem that the multi-homing access shortest path bridging network method is too complicated in the prior art, and achieves the technical effect of realizing multi-homing access shortest path bridging network without changing the existing protocol message.

Description

technical field

[0001] The present invention relates to the field of communications, in particular to a method and device for multi-homing access to a shortest path bridging network. Background technique

[0002] As the application of Ethernet continues to expand from LAN to MAN and backbone network, Ethernet technology is also evolving. The International Standards Organization Institute of Electrical and Electronics Engineers (Institute of Electrical and Electronics Engineers, referred to as IEEE) released the 802.1ah Provider Backbone Bridge (Provider Backbone Bridges, referred to as PBB) standard and 802.1ah in August 2008 and June 2012 respectively. aq Shortest Path Bridging (Shortest Path Bridging, referred to as SPB) standards, these two standards respectively stipulate the data plane and control plane of the Ethernet applied to the network backbone layer.

[0003] The PBB data plane adopts PBB encapsulation (also known as MAC-in-MAC encapsulation). The specific encap...
