5. Configure Router D:
# Enter MST region view, and configure the MST region name as example. Map VLAN 10, VLAN

MST region as 0.

6. Verify the configuration:
In this example, suppose Router B has the lowest root bridge ID. As a result, Router B is elected as
the root bridge of 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 Router A.
