By default, all VLANs map to MST instance zero (0) unless you are using the vlan range command to
map the VLANs to a non-zero instance. The no version of this command removes the instance-related
configuration.
Example
OS10(conf-mst)# instance 1 vlan 2-10
OS10(conf-mst)# instance 2 vlan 11-20
OS10(conf-mst)# instance 3 vlan 21-30
