Example 3: Configure Multiple Spanning Tree (MSTP) on the MCT Clients
MSTP (802.1s) allows mutliple VLANs to be managed by a single STP instance, and several VLANs
can be mapped to a reduced number of spanning-tree instances. Use MSTP on MCT clients to ensure
loop-free topology for one or more VLANs that have a similar Layer 2 topology.
MSTP requires that BPDU flooding be enabled on the MCT Cluster devices. This example is based on
the network topology shown in
on page 209.
Router-1 configuration
Router-1(config)# bpdu-flood-enable
Warning - Any recieved untagged BPDUs will now be flooded to all the ports.
Router-2 configuration
Router-2(config)# bpdu-flood-enable
Warning - Any received untagged BPDUs will now be flooded to all the ports.
Client-1 configuration
Client-1(config)# mstp scope all
Enter MSTP scope would remove STP and topology group related configuration for system
Are you sure? (enter ‘y’ or ‘n’): y
‘MSTP Start’ need to be entered in order to activate this MSTP feature
Client-1(config)# mstp start
Client-1(config)# mstp instance 1 vlan 1901
