To set an MSTP device as the root bridge in a specific MSTI, use this command with the MSTI specified. To set an MSTP device in the CIST or an STP/RSTP device as the root bridge, use this command without specifying any MSTI. Once you specify the device as the root bridge, you cannot change the priority of the device. Related commands: stp priority and stp root secondary.
