Save the routing settings so that they are valid after a network restart
Create a file named Route-eth0 under the/etc/sysconfig/network-script/directory
Vi/etc/sysconfig/network-script/route-eth0
Add content in this file in the following format

192.168.1.0/24 via 192.168.0.1

Restart network authentication


There are a few lines in/etc/rc.d/init.d/network:

# Add non interface-specific static-routes.
if [-f/etc/sysconfig/static-routes]; Then
grep "^any"/etc/sysconfig/static-routes | While read ignore args; Do
/sbin/route add-$args
Done
Fi

In other words, adding static routes to the/etc/sysconfig/static-routes file is OK.

If you join:
Route add-net 11.1.1.0 netmask 255.255.255.0 GW 11.1.1.1

The format of the static-routes is
Any net 11.1.1.0 netmask 255.255.255.0 GW 11.1.1.1
