Use the display ospf peer command to display OSPF neighbors on Switch A. Note
that Switch A has three neighbors.
The state of each neighbor is full. This means that Switch A has formed adjacencies
with all neighbors. (Switch A and Switch C can act as the DR and BDR only when they
establish adjacencies with all the switches in the network.) Switch A acts as the DR,
while Switch C acts as the BDR. Any other neighbor is DRother (neither DR nor BDR).
# Change the priority of Switch B to 200.
<SwitchB> system-view
[SwitchB] interface Vlan-interface 1
[SwitchB-Vlan-interface1] ospf dr-priority 200
