To add routes whenever a network gets started automatically we need to create a per-interface route file. For examples if we can reach network '10.10.0.0/16' via IP '10.3.3.2' connected to interface 'eth1' then we can create file named '<tt>/etc/sysconfig/network-scripts/route-eth1</tt>' with following lines: | To add routes whenever a network gets started automatically we need to create a per-interface route file.

To add routes whenever a network gets started automatically we need to create a per-interface route file. For examples if we can reach network '10.10.0.0/16' via IP '10.3.3.2' connected to interface 'eth1' then we can create file named '/etc/sysconfig/network-scripts/route-eth1' with following lines:
GATEWAY0=10.3.3.2 NETMASK0=255.255.0.0 ADDRESS0=10.10.0.0
If we want to add additional routes, for example to network '10.11.0.0/16' via '10.3.3.3' then we can use
GATEWAY1=10.3.3.3 NETMASK1=255.255.0.0 ADDRESS1=10.11.0.0 GATEWAY0=10.3.3.2 NETMASK0=255.255.0.0 ADDRESS0=10.10.0.0
This way we can add as many static routes as we want. These routes would remain even after 'service network restart' or machine reboot.
