With the introduction of Redhat version 8 and continued into version 9, the /etc/sysconfig/static-routes file no longer seems to function correctly.
Linux static routes changed in 8.0 to a new format. Now you are to create a file in /etc/sysconfig/network-scripts for each Ethernet interface you wish to create static routes on.
The syntax for this file is different from the traditional route format used in /etc/sysconfig/static-routes . Redhat has yet to document the change on their web site as of June 2003.
Syntax based on a usenet post go to /etc/sysconfig/network-scripts, make a file called route-devicename (ex: route-eth0) and populate it with your static routes for that device so if you wanted to make a static route to the 192.168.0.0/24 network through 220.127.116.11 type:
192.168.0.0/24 via 18.104.22.168
Persistent static routes for ANY linux distribution
You may use this method to add static routes and it will work under any Linux distribution. However, it is considered by some a ‘hack’ or the ‘ugly way’.
Edit your /etc/rc.local file and add your static routes using the route statement.
route add -net 10.10.98.0 netmask 255.255.255.0 gw 10.164.234.132 dev eth1
route add -net 10.164.234.96 netmask 255.255.255.252 gw 10.164.234.132 dev eth1
route add -net 10.164.234.112 netmask 255.255.255.240 gw 10.164.234.132 dev eth1
Force the old static-routes file to work under Redhat 9
Clear out the new /etc/sysconfig/network-scripts/ifup-routes script so that you can populate it with the original shell script from Redhat 7.x.
cat /dev/null > /etc/sysconfig/network-scripts/ifup-routes
type in the following (or copy and paste) not including the tilde lines:
# adds static routes which go through device $1
if [ «$1» = «» ]; then
echo «usage: $0
if [ ! -f /etc/sysconfig/static-routes ]; then
# note the trailing space in the grep gets rid of aliases
grep «^$1 » /etc/sysconfig/static-routes | while read device args; do
/sbin/route add -$args $device
grep «^any » /etc/sysconfig/static-routes | while read ignore type net netmask mask bogus dev ; do
if [ «$dev» = «$1″ ]; then
/sbin/route add -$type $net $netmask $mask $dev
Remember to use /etc/sysconfig/network for your default gateway
If you only intend to add one route, your default gateway, then you need not worry about the static routes file or using the route command. Simply add your default gateway in /etc/sysconfig/network.
