instance instance-list: Configures the device as a secondary root bridge in the MSTIs that are
specified by an instance list, in the format of instance-list = { instance-id [ to instance-id ] }&<1-10>,
where &<1-10> indicates that you can specify up to 10 instances or instance ranges. The
instance-id argument is in the range of 0 to 4094, and the value 0 represents the CIST. If you do not
specify this option, the command configures the device as the secondary root bridge in the MSTP
CIST or as the primary root bridge of STP or RSTP.
