Configuring Static IP Unicast Routing
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.
When an interface goes down, all static routes through that interface are removed from the IP routing
table. When the software can no longer find a valid next hop for the address specified as the forwarding
router's address in a static route, the static route is also removed from the IP routing table.
Monitoring and Maintaining the IP Network
You can specific statistics for the routing table or database. Use the privileged EXEC commands in
