Protocol Deep Dive: OSPF
This course is focused on providing you with a greater depth of OSPF knowledge to help ensure your ability to configure and troubleshoot it in real environments.
What you'll learn
In this course, Protocol Deep Dive: OSPF, you will learn foundational knowledge of OSPF. First, you will learn about OSPF's essential concepts, which will then be built on as the course continues. Next, you'll focus on OSPF relationships: how they work, what can prevent them from working, as well as a closer look at the OSPF packet and how information is exchanged between OSPF devices. You'll also take a closer look at how OSPF implements hierarchy through the use of areas, including what their effect is, the different area types, as well as the different additional messages that are used. Finally, you'll spend some additional time in the lab and look over how different issues can be found and fixed. When you are finished with this course, you will have the skills and knowledge of OSPF needed to successfully navigate its use in most common enterprise environments.
