Which command would be used to determine if an OSPF routing protocol- initiated relationship had been made with an adjacent router?

• ping
• show ip interface brief
• show ip ospf neighbor
• show ip protocols

Explanation: While the show ip interface brief and ping commands can be used to determine if Layer 1, 2, and 3 connectivity exists, neither command can be used to determine whether a particular OSPF or EIGRP-initiated relationship has been made. The show ip protocols command is useful in determining the routing parameters such as timers, router ID, and metric information associated with a specific routing protocol. The show ip ospf neighbor command shows if two adjacent routers have exchanged OSPF messages in order to form a neighbor relationship.
