Question

question 25
what command would be used to determine if a routing protocol - initiated relationship had been made with an adjacent router?
show ip ospf neighbor
ping
show ip protocols
show ip interface brief

Explanation:

• show ip ospf neighbor: This command is specifically used to display OSPF (Open Shortest Path First) neighbor relationships. It shows details about adjacent routers with which OSPF - based relationships have been established.
• ping: It is mainly used to test basic network connectivity (e.g., whether an IP address is reachable) and does not directly show routing - protocol - initiated relationships.
• show ip protocols: This command provides information about the IP routing protocols configured on the router (such as which protocols are enabled, their parameters), but not the specific neighbor relationships.
• show ip interface brief: It is used to display a summary of the IP - related status of interfaces (e.g., IP address, up/down status of the interface), not neighbor relationships.

Answer:

show ip ospf neighbor
