In this course, you'll review OSPF concepts you should already be familiar with, including commands and configuration. Then, you'll learn about the roles of designated routers and backup designated routers in OSPF. You'll explore OSPF best path selection and how OSPF determines cost. Next, you'll learn how OSPF virtual links can solve issues with areas that aren't directly connected to Area 0. Finally, you'll examine why OSPF networks need default routes propagated through the network. This course is one of a series that prepares you for the 300-410: Implementing Cisco Enterprise Advanced Routing and Services (ENARSI) certification exam.
