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:
Example 11-18 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. Use the show ip route privileged EXEC command to view information about the static IP route
(
Example 11-19 ).
Command Purpose
Step 1 Router# configure terminal Enters global configuration mode.
Step 2 Router(config)# ip route prefix mask
{ address | interface } [distance]
Establishes a static route. Illustrated in
Example 11-18 .
Step 3 Router(config)# end Returns to privileged EXEC mode.
Step 4 Router# copy running-config startup-config (Optional) Saves your entries in the
configuration file.
