They are manually configured by the administrator. In arelatively simple network, you only need to configure static routes to make routers worknormally. Proper configuration and usage of static routes can improve networkperformance and ensure sufficient bandwidth for important applications.When the network topology changes, static routes may become unreachable becausethey cannot adapt themselves to the change automatically, thus resulting in networkinterruption. In this case, the network administrator needs to modify the configuration ofstatic routes manually.Static routes are divided into three types:z Reachable route: normal route. If a static route to a destination is of this type, theIP packets destined for this destination will be forwarded to the next hop. It is themost common type of static routes.z Unreachable route: route with the reject attribute. If a static route to a destinationhas the reject attribute, all the IP packets destined for this destination will bediscarded, and the source hosts will be informed of the unreachability of thedestination.
