Usage guidelines
Spanning tree devices belong to the same MST region only when they are connected through a physical link and configured with the same details as follows:
Format selector (0 by default and not configurable).
MST region name.
MST region revision level.
VLAN-to-instance mapping entries in the MST region.
As a best practice, use this command to determine whether the MST region configurations to be activated are correct. Activate them only when they are correct.
