User Guidelines
For two or more switches to be in the same MSTP region, they must contain the
same VLAN mapping, the same configuration revision number, and the same
name.
Example
switchxxxxxx(config)# spanning-tree mst configuration
switchxxxxxx(config-mst)# instance 1 vlan 10-20
switchxxxxxx(config-mst)# name region1
switchxxxxxx(config-mst)# revision 1
To configure the path cost for MSTP calculations, use the spanning-tree mst cost
Interface Configuration mode command. If a loop occurs, the STP considers the
path cost when selecting an interface to put in the Forwarding state.
To revert to its default setting, use the no form of this command.
