Changes to survive a reboot can be set in
/etc/sysconfig/networking/devices/route-ethX
Other profiles for switching between different configurations can be found in
/etc/sysconfig/networking/profiles/default/route-ethX

Hi
add the route command in linux
# route add -net 10.10.1.1/24 ethx
Alternate is by ip command
# ip route add 10.10.2.2/24 ethx
after that configure gateway,netmask and ip in route-ethx file located in /etc/sysconfig/network-scripts dir.
Thanks.
Adding the route command in Linux
Route traffic via 192.168.0.5 gateway destined to 192.168.1.16 :
route add -net 192.168.1.16 netmask 255.255.255.240 gw 192.168.0.5
This will handle all the traffice from your client systems destined to the 192.168.1.16 subnet.
The resources that will be accessed are in the range 192.168.1.16 – 192.168.1.30
I have tried it on Suse Linux, and i belive other flavors are similar or close to this .
Thanks
Prosper
To add default route for a host:
#route add 192.168.0.1 gw 10.0.0.1
“where 192.168.0.1 is destination host, gw commad to specify gateway and 10.0.0.1 is the gateway to destination host. (Test on Feroda 11)”
Another way to add route at startup (testing on CentOS)
edit file /etc/rc.d/rc.local (add to end of file your route):
/sbin/route add -net 192.168.11.0 netmask 255.255.255.0 gw 10.0.0.1
After reboot check your route table:
/sbin/route
i want to add below command in Linux server.but here it is showing error

Dear Pankaj,
