Question:
Refer to the exhibit. A network administrator has configured OSPFv2 on the two Cisco routers as shown. PC1 is unable to connect to PC2. What should the administrator do first when troubleshooting the OSPFv2 implementation?

• Disconnect the serial link between router R1 and R2.
• Turn off OSPFv2.
• Implement the network 192.168.255.0 0.0.0.3 area 0 command on router R1.
• Test Layer 3 connectivity between the directly connected routers.

Explanation: A prerequisite for OSPFv2 neighbor relationships to form between two routers is Layer 3 connectivity. A successful ping confirms that a router interface is active and may be able to form an OSPF neighbor adjacency.
