OSPF
This chapter covers OSPF, the only link-state routing protocol covered by the CCIE Routing and
Switching exam blueprint. As with the other routing protocol chapters, this chapter includes
most of the features, concepts, and commands related to OSPF. Chapter 10 “IGP Route
Redistribution, Route Summarization, and Default Routing,” covers a few other details of OSPF,
in particular, route redistribution, route filtering in redistribution, and route summarization.
