What command summarizes the statuses of all the OSPF neighbors?

The command that summarizes the statuses of all the OSPF (Open Shortest Path First) neighbors is specifically designed to provide detailed information about the OSPF neighbors configured on the device. By using this command, network administrators can view the status of each OSPF neighbor, including their current state (such as FULL, 2WAY, etc.), the interfaces used for OSPF, and other critical information that helps in network troubleshooting and monitoring.

This command specifically focuses on the neighbor relationships, which are crucial for OSPF operation, as the protocol relies on these adjacencies for route exchange and network topology updates. Understanding the state of OSPF neighbors is essential for ensuring optimal routing and performance across a network.

The other commands listed serve different purposes and do not provide a summary of OSPF neighbor statuses. For instance, commands that deal with OSPF database or interfaces may provide information about OSPF routes or the performance of OSPF over specific interfaces but do not summarize the neighbor relationships directly.
