| 11.2.2 | Why use a static route
Static routing has several useful applications. Whereas dynamic routing tends to reveal everything known about an internetwork, for security reasons, you may want to hide parts of an internetwork. Static routing enables you to specify the information you want to reveal about restricted networks. When a network is accessible by only one path, a static route to the network can be sufficient. This type of network is called a stub network. Configuring static routing to a stub network avoids the overhead of dynamic routing.
