The following example shows that both VLT nodes are configured with the same MST VLAN-to-instance mapping.
VLT Peer 1 confoguration
OS10(config)# spanning-tree mode mst
OS10(config)# spanning-tree mst configuration
OS10(conf-mst)# instance 1 vlan 2-10
OS10(conf-mst)# revision 10
OS10(conf-mst)# name ExampleMSTregion
VLT Peer 2 confoguration
OS10(config)# spanning-tree mode mst
OS10(config)# spanning-tree mst configuration
OS10(conf-mst)# instance 1 vlan 2-10
OS10(conf-mst)# revision 10
OS10(conf-mst)# name ExampleMSTregion
