Configuring Static Routes

Static routes are user-defined routes that cause packets moving between a source and a destination to
take a specified path. Static routes can be important if the router cannot build a route to a particular
destination. They are also useful for specifying a gateway of last resort to which all unroutable packets
are sent.
Beginning in privileged EXEC mode, follow these steps to configure a static route:
Command
Step 1
Router# configure terminal
Step 2
Router(config)# ip route prefix mask {
address | interface } [ distance ]
Step 3
Router(config)# end
Step 4
Router# copy running-config startup-config
The following example shows a static route:
Router(config)# ip route 0.0.0.0 0.0.0.0 192.168.2.1
Use the no ip route prefix mask {address | interface} global configuration command to remove a static
route.
This is an example of output from the show ip route privileged EXEC command with a static route
configured:
Router# show ip route
Codes: C - connected, S - static, I - IGRP, R - RIP, M - mobile, B - BGP
