5. Configure Device C:
# Enter MST region view, configure the MST region name as example, map VLAN 10, VLAN 30,
and VLAN 40 to MSTI 1, MSTI 3, and MSTI 4 respectively, and configure the revision level of the
MST region as 0.

6. Verify the configuration:
NOTE:
In this example, suppose Device B has the lowest device ID, and as a result, Device B will be elected as the
root bridge in MSTI 0.
You can use the display stp brief command to display brief spanning tree information on each
device after the network is stable.
# Display brief spanning tree information on Device A.
