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.
