Configuring an MST region
Two or more spanning tree devices belong to the same MST region only if they are configured to have the
same format selector (0 by default, not configurable), MST region name, MST region revision level, and
VLAN-to-instance mapping entries in the MST region, and they are connected via a physical link.
The configuration of MST region-related parameters, especially the VLAN-to-instance mapping table, will
result in a new spanning tree calculation. To reduce the possibility of topology instability, the MST region
configuration takes effect only after you activate it by using the active region-configuration command, or
enable a spanning tree protocol by using the stp enable command if the spanning tree protocol is
disabled.

Configuring the root bridge or a secondary root bridge
You can have MSTP determine the root bridge of a spanning tree through MSTP calculation, or you can
specify the current device as the root bridge or as a secondary root bridge.
