Configuring Static Unicast Routes
Static unicast 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 and are 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
configure terminal
Step 2
ip route prefix mask {address | interface} [distance]
Step 3
end
Step 4
show ip route
Step 5
copy running-config startup-config
Use the no ip route prefix mask {address | interface} global configuration command to remove a static
route.
The switch retains static routes until you remove them. However, you can override static routes with
dynamic routing information by assigning administrative distance values. Each dynamic routing
protocol has a default administrative distance, as listed in
overridden by information from a dynamic routing protocol, set the administrative distance of the static
route higher than that of the dynamic protocol.

Purpose
Set the maximum number of parallel paths for the protocol routing
table. The range is from 1 to 8; the default is 4 for most IP routing
protocols, but only 1 for BGP.
Return to privileged EXEC mode.
Verify the setting in the Maximum path field.
