MSTP Overview
MSTP maps VLANs into STP instances, using various load balancing
scenarios. As a result of this partitioning into instances, if port A is blocked in
one STP instance, the same port can be placed in the Forwarding State in
another STP instance.
In addition, packets assigned to various VLANs are transmitted along
different paths within Multiple Spanning Trees Regions (MST Regions).
Regions are one or more Multiple Spanning Tree bridges by which frames can
be transmitted.
