] [
permanent
]
Example:
Router(config)# ip route 192.168.24.0
255.255.255.0 172.28.99.2
Establishes a static route.
Step 5
ip default-network

or
ip route
dest-prefix mask
next-hop-ip-address
Example:
Router(config)# ip default-network 192.168.24.0
Example:
Router(config)# ip route 0.0.0.0 0.0.0.0
172.28.99.1
Selects a network as a candidate route for computing the
gateway of last resort.
Creates a static route to network 0.0.0.0 0.0.0.0 for
computing the gateway of last resort.
Step 6
end
Example:
Router(config)# end
Returns to privileged EXEC mode.
Step 7
show ip route
Example:
Router# show ip route
Displays the current routing table information.
•
Verify that the gateway of last resort is set.
