Edit route table

I have created a router using RedHat 7.0 for my home network. I was using linuxconf to create static route tables. I accidently typed in the wrong route and now I have two routes for my 192.168.0.0 network. I tried to delete the route using routedel 192.168.0.0 and received an error. I then tried route del 192.168.0.0 dev eth1 to delete the wrong entry. I still get an error. This computer does not have x windows installed since it is only a P90 with 32MB of ram.

How can I delete the incorrect route? Is there a file or files that I can manually edit?
