About this learning path

This intermediate learning path on Open Shortest Path First (OSPF) is tailored for network professionals who are ready to move beyond the basics and develop a deeper, more practical understanding of OSPF in enterprise networks. The path explores key deployment and optimization techniques including route redistribution between OSPF and other protocols, effective route summarization at ABRs and ASBRs, and implementing route filtering to control routing information flow. It also covers OSPF area types in detail, including standard stub areas, totally stubby areas, and Not-So-Stubby Areas (NSSA), with guidance on when and how to use each to simplify routing and improve scalability. Throughout, the learning path emphasizes best practices, common design mistakes to avoid, and hands-on configuration strategies to help learners confidently apply OSPF in complex, real-world environments.
