Refer to the exhibit. Router OldR is replacing another router on the network with the intention of having OldR and R2 exchange routes. After the engineer applied the initial OSPF configuration, the routes were still missing on both devices. Which command sequence must be issued before the clear IP ospf process command is entered to enable the neighbor relationship?

A. OldR(config)#interface g0/0/0 OldR(config-if)#ip ospf hello-interval 15 B. OldR(config)#router ospf 1 OldR(config-router)#network 192.168.1.0 255.255.255.0 area 2 C. OldR(config)#interface g0/0/0 OldR(config-if)#ip ospf dead-interval 15 D. OldR(config)#router ospf 1 OldR(config-router)#no router-id 192.168.1.1
