configured or dynamically learned using a routing protocol. Static routes are manually
configured and define an explicit path between two networking devices. Unlike a dynamic
routing protocol, static routes are not automatically updated and must be manu
reconfigured if the network topology changes. The benefits of using static routes include
security and resource efficiency. Static routes use less bandwidth than dynamic routing
protocols and no CPU cycles are used to calculate and communicate routes. The main
disadvantage to using static routes is the lack of automatic reconfiguration if the network
topology changes.
Static routes can be redistributed into dynamic routing protocols but routes generated by
dynamic routing protocols cannot be redistributed into the static routing table. No algorithm
exists to prevent the configuration of routing loops that use static routes.
Static routes are useful for smaller networks with only one path to an outside network and to
provide security for a larger network for certain types of traffic or links to other networks that
need more control. In general, most networks use dynamic routing protocols to
communicate between networking devices but may have one or two static routes
configured for special cases
