stp region-configuration (MSTP process view)

Function

The stp region-configuration command displays a Multiple Spanning Tree (MST) region view.

The undo stp region-configuration command restores the default MST region configuration.

By default, the configuration of an MST region is as follows:

MST region name: MAC address of the IPU of the device.

MSTP revision level: 0.

VLAN mapping table: all VLANs are mapped to Common and Internal Spanning Tree (CIST).

Usage Guidelines

Usage Scenario

MSTP divides a switching network into multiple regions. Each region is a Multiple Spanning Tree (MST) region and has independent Multiple Spanning Trees. Each spanning tree is called a Multiple Spanning Tree instance (MSTI).

Two devices belong to the same MST region if their following configurations are the same:

MST region name
Mappings between VLANs and MSTIs
Revision level of the MST region
Before setting the preceding parameters on a device or process, run the stp region-configuration command to enter the MST region view.

Follow-up Procedure

Run the region-name command to set the MST region name.
Run the instance command to set mappings between VLANs and MSTIs.
Run the revision-level name command to set a revision level for the MST region.

Example

# Enter the MST process region view.
