This course offers a deep, design-focused look at OSPF, one of the most widely deployed routing protocols in the world, taught by legendary network architect Russ White.

You'll learn not just the how, but the why behind OSPF’s design, internal mechanisms, and behavior in real-world networks.

     What You’ll Learn:

• OSPF Flooding, Internals, and Externals
  Understand how OSPF floods LSAs efficiently and the critical differences between internal and external route handling. Learn how SPF calculation is affected by LSA propagation and what design trade-offs exist.

• OSPF Flooding Domains, Aggregation, and Summarization
  Explore how OSPF scales across large networks using areas, LSA type control, and route summarization. You'll learn to build scalable designs while maintaining fast convergence.

• OSPF Neighbors and Neighbor Types
  Dive into how routers form neighbor relationships, the role of DR/BDR elections, and how different network types (broadcast, point-to-point, NBMA) affect adjacency formation and design.

• OSPF Policy and Control
  Learn how to influence routing decisions and topology visibility using OSPF filtering, route maps, and redistribution techniques,  essential for multi-protocol environments and migration scenarios.

Whether you're preparing for network design certifications like CCDE or want to master the OSPF internals as a network engineer or architect, this course delivers critical knowledge explained in a clear, intuitive way by one of the industry's top experts.
