KB No. 2003: ADDING A STATIC ROUTE

How to add a static route and make that route persistent.

Objective

Add a static route and make this route persistent.

STEPS

For example, use IP address 192.168.1.100 to reach network 192.168.2.0/24:

route add -net 192.168.2.0 netmask 255.255.255.0 gw 192.168.1.100

Make this route available each time the eth0network interface is activated:

• For Debian-like (Debian, Ubuntu, etc.):

  Write the following line in the /etc/network/interfaces file:

  up route add -net 192.168.2.0 netmask 255.255.255.0 gw 192.168.1.100

• For CentOS, RedHat, etc.:

  echo "192.168.2.0/24 via 192.168.1.100" >> /etc/sysconfig/network-scripts/route-eth0
