STP/RING PAGE - CONFIGURING MSTP
The MSTP protocol adds a new concept called a Region to the Spanning Tree algorithm.
Unlike RSTP and STP, inside each MSTP Region, there can be more than one instance of
Spanning Tree Protocol running simultaneously. The MSTP protocol can then map multiple
VLANs to each instance of Spanning Tree protocol to provide load balancing among the
switches. Between Regions, the MSTP runs a single instance of Spanning Tree similar to,
and is backward compatible with, the RSTP protocol.
