On SwitchD, GE 1/0/2 functions as the alternate port in the CIST. SwitchD and SwitchC are in
different regions; therefore, GE 1/0/2 of SwitchD also functions as the alternate port in MSTI1.
GE 2/0/1 of SwitchD is the root port in the CIST. The priority of SwitchD is higher than that of
SwitchB in MSTI1; therefore, GE 2/0/1 also functions as the designated port in MSTI1.
