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.
