LSP (Layered Service Provider) information flooding method and equipment in SPBM (Shortest Path Bridging MAC)

Spbm中的lsp信息泛洪方法及设备

Abstract

The invention discloses an LSP (Layered Service Provider) information flooding method and equipment in an SPBM (Shortest Path Bridging MAC). A data plane of each backbone network bridging equipment in the SPBM network is maintained by a unicast FDB (Forwarding Database) table. The method comprises the following steps of: generating new LSP information according to the variation of network topology after the variation of the network topology is detected; and using B-MAC (Multiplexed Analogue Components) addresses and corresponding B-VLANs (Virtual Local Area Network) of all the other backbone network bridging equipment locally saved to create an IS-IS (Intermediate System to Intermediate System) LSP message with the new LSP information and sending out the IS-IS LSP message by a transceiving port corresponding to the B-MAC address in the unicast FDB table, wherein the B-MAC address in the IS-IS LSP message refers to the B-MAC address of the other backbone network bridging equipment, and a B-VLAN tag is filled with the B-VLAN corresponding to the B-MAC address of the other backbone network bridging equipment. According to the invention, the flooding speed is raised, time spent in the flooding process is shortened, and the convergence performance of the SPBM network is improved.
本发明公开了一种SPBM中的LSP信息泛洪方法及设备,SPBM网络中的每一个骨干网网桥设备的数据平面维护有单播FDB表,该方法包括:检测到网络拓扑发生变化之后,根据网络拓扑的变化生成新的LSP信息;使用本地保存的每一个其他骨干网网桥设备的B-MAC地址及其对应的B-VLAN,构造一个携带有新的LSP信息的IS-ISLSP报文,并将该IS-IS LSP报文通过单播FDB表中与该B-MAC地址对应的出接口发送出去;其中,该IS-IS LSP报文中的B-DMAC地址为该其他骨干网网桥设备的B-MAC地址,B-VLAN标签填充有该其他骨干网网桥设备的B-MAC地址对应的B-VLAN。本发明提高了泛洪的速度,缩短了泛洪过程所花费的时间,提升了SPBM网络的收敛性能。
