Static Routing
In environments that use static routing, routes and route information are entered into the routing tables manually. Not only can this be a time-consuming task, but also errors are more common. Additionally, when there is a change in the layout, or topology, of the network, statically configured routers must be manually updated with the changes. Again, this is a time-consuming and potentially error-laden task. For these reasons, static routing is suited to only the smallest environments with perhaps just one or two routers. A far more practical solution, particularly in larger environments, is to use dynamic routing.
