Configuring Multiple Spanning Tree

MSTP operation maps VLANs into STP instances. Multiple Spanning Tree provides differing load
balancing scenario. For example, while port A is blocked in one STP instance, the same port is 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.
