1.2.2 MST Region Configuration
I. Configuration procedure
Follow these steps to configure an MST region:

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 take effect:
z Activating the new MST region-related settings by using the active
region-configuration command
z Enabling MSTP by using the stp enable command
