Note:
Switches belong to the same MST region only when they have the same MST region
name, VLAN mapping table, and MSTP revision level.
II. Configuration example
# Configure an MST region, with the name being “info”, the MSTP revision level being
level 1, VLAN 2 through VLAN 10 being mapped to spanning tree instance 1, and VLAN

also manually specify the current switch as a root bridge by using the corresponding
commands.
