Dell PowerEdge FN I/O Module Configuration Guide 9.10(0.0)

Example of Assigning and Verifying the Root Bridge Priority

By default, the simple configuration shown previously yields the same forwarding path for both MSTIs. The following example shows how R3 is assigned bridge priority 0 for MSTI 2, which elects a different root bridge than MSTI 2.

To view the bridge priority, use the show config command from PROTOCOL MSTP mode.

Dell(conf-mstp)#msti 2 bridge-priority 0
                                 
                                 Dell(conf-mstp)#show config
                                 !
                                 protocol spanning-tree mstp
                                 MSTI 2 bridge-priority 0
                                 Dell(conf-mstp)#
