Troubleshooting is a critical skill in network management, and OSPF is no exception. This section covers troubleshooting various common issues that may arise in OSPF configurations. One of the most common problems in OSPF is the failure of neighbor routers to form an adjacency.

Understanding how to troubleshoot OSPF enhances your problem-solving capabilities and ensures the network's overall health. This section will provide the knowledge and hands-on experience needed to pinpoint issues related to the OSPF neighbor adjacencies and traffic engineering.

The section includes the following lessons.
