add pemananet static route under RHEL5

Hi guys,
I have two network interfaces
Eth0 10.1.0.202 255.255.0.0 gw 10.1.0.1
Eth1 192.168.1.22 255.255.255.0 gw 192.168.1.1
Default internet route is 10.1.0.1

I want to add a permanent route for eth1 192.168.1.122 to be forwarded to 192.168.1.1
I did some search they say open file /etc/sysconfig/network-scripts/route-eth0 and add static route there example:
192.168.1.0/24 via 192.168.1.1

But I don’t have that file under that directory, I am using RHEL5, where is that file?

As I told you above it is not a normal practice to assign a gateway for any address located in the local network of an interface. I really suspect that your problem is not with the routing but the assignment of the address 192.168.1.122 to the 192.168.1.1 interface.

OK, I know what you mean, but mean while, just for the same of learning, i did wwhat you said after restarting network service i got following error

Bringing up interface eth1: RTNETLINK answers: Invalid argument

i did following:
#vi route-eth1
GATEWAY0=192.168.1.1
NETMASK0=255.255.255.0
ADDRESS0=192.168.1.122

that is true under command line this will create the route, but it wan't stay after restarting network services. I even created a file under /etc/sysconfig/network-scripts, named route-eth1 and added your line (ip route add 192.168.1.0 via 192.168.1.1), but i got error
(Bringing up interface eth1: Error: an inet prefix is expected rather than "ip") how can i make that route permanent?

Ok under the file you created the syntax should be

192.168.1.0/24 via 192.168.1.1

This should be the only line under your file

Restart network and try

/etc/init.d/network restart
