stp region-configuration
Function
The stp region-configuration command displays the MST region view.
The undo stp region-configuration command restores the default configuration of the MST region.
The default parameters of the MST regions are as follows:
MST region name: MAC address of the main processing unit of the switching device.
MSTP revision level 0.
VLAN mapping table: all VLANs are mapped to CIST.
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.
- 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, run the stp region-configuration command to enter the MST region view first.
Follow-up Procedure
- 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.
