Introduction to Static Route

Static Route

Static routes are special routes. They are manually configured by the administrator. In a relatively
simple network, you only need to configure static routes to make routers work normally. Proper
configuration and usage of static routes can improve network performance and ensure sufficient
bandwidth for important applications.
When the network topology changes, static routes may become unreachable because they cannot
adapt themselves to the change automatically, thus resulting in network interruption. In this case, the
network administrator needs to modify the configuration of static routes manually.
Static routes are divided into three types:
Reachable route: normal route. If a static route to a destination is of this type, the IP packets
destined for this destination will be forwarded to the next hop. It is the most common type of static
routes.
Unreachable route: route with the reject attribute. If a static route to a destination has the reject
attribute, all the IP packets destined for this destination will be discarded, and the source hosts will
be informed of the unreachability of the destination.
