Specifying the MST Region Configuration and Enabling MSTP
For two or more switches to be in the same MST region, they must have the same VLAN-to-
instance mapping, the same configuration revision number, and the same name. A region can
have one member or multiple members with the same MST configuration; each member must be
capable of processing RSTP BPDUs. There is no limit to the number of MST regions in a network,
but each region can support up to 16 spanning-tree instances. You can assign a VLAN to only
one spanning-tree instance at a time.
