Hi,

To make a static route using one of the interface (in our case gigabit
interface), first we need to delete the present route and add the new
route.Commands are follows,

# route -n (this will show the present routing gateway)
# route del default (this will delete the present route)
# route add default gw ipaddressofthegigabit

# route -n (Shows the route is configured to gigabit)

Now all the traffic will route through the gigabit card.

Cheers!
