By understand the architecture, allow you effectively maintain and operate the correct spanning
tree. One VLAN can be mapped to an instance. The maximum Instance of the switch is 16, with
the range 0-15. The MSTP builds a separate Multiple Spanning Tree (MST) for each instance to
maintain connectivity among each of the assigned VLAN groups. An Internal Spanning Tree (IST)
is used to connect all the MSTP switches within an MST region. An MST Region may contain
multiple MSTP Instances.
MSTP connects all bridges and LAN segments with a single Common and Internal Spanning Tree
that is formed as a result of the running spanning tree algorithm between switches that support
the STP, RSTP, MSTP protocols.
To configure the MSTP setting, the STP Mode of the RSTP Settings page should be changed to
MSTP mode first. After enabled MSTP mode, user can go to the MSTP Settings page.
