MSTP is based on instances. An instance is a group of VLAN’s with a common spanning tree. A single VLAN
cannot be associated with multiple instances.
Switches with same instance - VLAN mapping, revision number and region names creates a region. Switches
in the same region exchange bridge protocol data units (BPDU) with instance record information.
Example
The example below creates an instance named 10 and maps VLAN 20 to it.
RFS7000(config-mst)#instance 10 vlan 20
RFS7000(config-mst)#
<1-15> Defines the instance ID to which the VLAN is associated.
vlan <VLAN_ID> Defines the VLAN ID for its association with an instance.
