A network engineer is configuring OSPF between router R1 and router R2. The engineer must ensure that a DR/BDR election does not occur on the Gigabit Ethernet interfaces in area 0. Which configuration set accomplishes this goal?

A. R1 (config-if) #interface Gi0/0
R1 (config-if) #ip ospf network point-to-point
R2 (config-if) #interface Gi0/0
R2 (config-if) #ip ospf network point-to-point

B. R1 (config-if) #interface Gi0/0
R1 (config-if) #ip ospf network broadcast
R2(config-if)#interface Gi0/0
R2(config-if)#ip ospf network broadcast

C. R1(config-if)#interface Gi0/0
R1(config-if)#ip ospf database-filter all out
R2(config-if)#interface Gi0/0
R2(config-if)#ip ospf database-filter all out

D. R1(config-if)#interface Gi0/0
R1(config-if)#ip ospf priority 1
R2(config-if)#interface Gi0/0
R2(config-if)#ip ospf priority 1


Correct Answer: A


Section: (none)
Explanation
Explanation/Reference:
Broadcast and Non-Broadcast networks elect DR/BDR while Point-to-point/multipoint do not elect DR/BDR. Therefore we have to set the two Gi0/0 interfaces to
point-to-point or point-to-multipoint network to ensure that a DR/BDR election does not occur.
