As you know, routers use routing tables to move packets between networks. As the name indicates, the routing table contains routes to directly connected networks and remotely connected networks. These routes are entered into the routing table manually and dynamically. The network administrator enters routes into the router's routing table manually, whereas dynamic routing protocols update the routes into router's routing table dynamically. That makes for both static routing and dynamic routing to have their pros and cons. In this section, we will learn how to configure static routes and default static routes on a Cisco router.
