Use the active region-configuration command to activate the settings of a multiple spanning tree 

(MST) region. 

Configuring MST region-related parameters (especially the VLAN-to-instance mapping table) can result 

in network topology jitter. To reduce network topology jitter caused by such a configuration change, 

multiple spanning tree protocol (MSTP) does not recalculate spanning trees immediately after the 

configuration change; it does this only after you activate the new MST region-related settings or enable 

MSTP; only then will the new settings begin to take effect. 

When you carry out this command, MSTP will replace the currently running MST region–related 

parameters with the parameters you have just configured and will perform spanning tree recalculation.
