Claim Text:
1. A method for making bridges join one Multiple Spanning Tree Protocol (MSTP) region during the MSTP region network topology establishment, comprising: receiving, by a downstream bridge, a region join packet sent by an upstream node, wherein the region join packet carries region information of the MSTP region, wherein the region information of the MSTP region comprises a triplet comprising a region name, an instance, and a revision level, wherein the region name indicates a name of the MSTP region, and wherein the instance indicates multiple spanning tree instances (MSTIs) in the MSTP region and a virtual local area network (VLAN) list corresponding to each MSTI; comparing, by the downstream bridge, the region name in the region information of the MSTP region with a region name configured on the downstream bridge; and configuring, by the downstream bridge, the region information of the MSTP region to the region information of the downstream bridge to join the MSTP region and generate the multiple MSTIs in the MSTP region when the comparison result indicates that the region name in the region information of the MSTP region is the same as the region name configured on the downstream bridge.
