Summary
As you have learned in this chapter, OSPF is a scaleable, standards-based link-state routing protocol. OSPF's benefits include no hop count limitation, the capability to multicast routing updates, faster convergence rates, and better path selection. You learned the basic steps to configuring OSPF in a single area: 1) establish router adjacencies, 2) select a designated router and a backup designated router, 3) discover routes, 4) select appropriate routes to use, and 5) maintain routing information.

In the next chapter, you will learn how to connect multiple OSPF areas in order to support a larger hierarchical routing environment. It discusses additional OSPF capabilities that you can configure, depending on the size of your network.
