Refer to the exhibit. A network administrator has configured OSPFv2 on the two Cisco routers as shown. The routers are unable to form a neighbor adjacency. What should be done to fix the problem?
- Remove the FastEthernet0/0 passive interface configuration on router R1.
- Add the command network 192.168.20.1 0.0.0.0 area 0 on router R1.
- Add the command network 192.168.30.0 0.0.0.255 area 0 on router R1.
- Change the IP address on S0/0 of router R2 to 192.168.20.2.
Answers Explanation & Hints: In order to form OSPFv2 neighbor adjacencies, two connected router interfaces must share the same subnet. Router R2 is shown in the topology with an IP address of 192.168.20.5 and does not exist on the same subnet as the 192.168.20.1 /30 IP address of S0/0 on router R1.
