One way to begin understanding the way the Internet works is to configure a router. It is also one of the primary topics on the CCNA exam, and one of the most important and sought after skills of employers. Routers are complex devices that can have a wide variety of possible configurations. In this chapter, you will practice configuring a router. You will do it many, many times. Practice with simulations and actual routers is the only way to learn this extremely important skill. Though the actual configuration will be fairly simple, the purpose of doing it so many times is to make it "second nature" to you.
