Configuring MST region-related parameters (especially the VLAN mapping table)
results in spanning trees being regenerated. To reduce network topology jitter caused
by the configuration, MSTP does not regenerate spanning trees immediately after the
configuration; it does this only after you perform one of the following operations, and
then the configuration can really takes effect:
Activating the new MST region-related settings by using the active
region-configuration command
Enabling MSTP by using the stp enable command
Note:
Switches belong to the same MST region only when they have the same MST region
name, VLAN mapping table, and MSTP revision level.
