Different regions can have the same revision level without
conflict.
8 - Bridge Identifier
The MAC address of the bridge. The bridge identifier is used as a
tie breaker in the selection of a root bridge when two or more
bridges have the same bridge priority value. This value cannot be
changed.
9 - Root Identifier
If this MAC address is the same as the bridge’s MAC address, then
the switch is also functioning as a root bridge. If the two MAC
addresses are different, then a different switch is functioning as
the root bridge. You cannot change this parameter. This
parameter is only displayed with MSTP is enabled.
