Static Routes

Static routes are commonly used when you are routing from a network to a stub network. A stub network (sometimes called a leaf node) is a network accessed by a single route. Static routes can also be useful for specifying a “gateway of last resort” to which all packets with an unknown destination address are sent. Following is the syntax for configuring a static route:

RouterX(config)# ip route network [mask] {address | interface}[distance] [permanent]

Summary of Static Routing

Routing is the process by which items get from one location to another. In networking, a router is the device used to route traffic. Routers can forward packets over static routes or dynamic routes based on the router configuration.
■ Static routers use a route that a network administrator enters into the router manually. Dynamic routes use a router that a network routing protocol adjusts automatically for topology or traffic changes.
■ Unidirectional static routes must be configured to and from a stub network to allow communications to occur.
■ The ip route command can be used to configure default route forwarding.
■ The show ip route command verifies that static routing is properly configured. Static routes are signified in the command output by “S.”
