Sample

In this case we setup a default route, which is where data packets will be sent if the router cannot determine the next hop:

california> enable
california# config t
california(config)# ip default-route 10.0.0.0
california(config)# ip route 192.168.0.0 255.255.0.0 10.0.0.1
california(config)# ip route 0.0.0.0 0.0.0.0 192.168.0.10

Example

> en
# config t
(config)# int e0
