Usage Guidelines

Usage Scenario

MSTP divides a switching network into multiple regions, each of which has multiple spanning trees and these spanning trees are independent of each other. Each spanning tree is called a multiple spanning tree instance (MSTI) and each region is called a multiple spanning tree (MST) region.

Two switching devices belong to the same MST region if they have the following parameters the same:

MST region name
Mappings between VLANs and MSTIs
Revision level of the MST region

If the preceding parameters need to be set for the current switching device or the current process, run the stp region-configuration command to enter the MST region view first.

Follow-up Procedure

After the stp region-configuration command is run to enter the MST region view, run the following commands:

Run the region-name command to set the MST region name.
Run the instance or the vlan-mapping modulo command to set the mappings between VLANs and MSTIs.
Run the revision-level name command to set the revision level of the MST region.

After entering the MST region view and setting the preceding parameters, run the active region-configuration command to activate the configurations of the MST region.
