Usage Guidelines
MSTP works based on instances. An instance is a group of VLANs with a common spanning tree. A
single VLAN cannot be associated with multiple instances.
Controllers with the same instance, VLAN mapping, revision number and region names define a
unique region. Controllers in the same region exchange bridge protocol data units (BPDUs) with
instance record information within it.
Example
The following example sets an instance named 10 and maps VLAN 20 to it:
RFController(config-mst)#instance 10 vlan 20
RFController(config-mst)#
<1-15> Defines the instance ID to which the VLAN is associated
vlan <vlan-id> Sets the VLAN ID for its association with an instance
