Overview

To add static routes that will be preserved after reboot, follow How do I configure static routes in Red Hat Enterprise Linux version 3?

This should work for at least RHEL 3, 4, and 5.

Example

In this example, I want to route traffic for network 10.226.223.0/24 using the gateway 149.122.23.9.

  • Add a route for the current session.
# route add -net 10.226.223.0/24 gw 149.122.23.9
  • Create an /etc/sysconfig/network-scripts/route-eth0 file to preserve this static route across reboots.
GATEWAY0=149.122.23.9
NETMASK0=255.255.255.0
ADDRESS0=10.226.223.0
