Assuming the network information below configured on the server itself with one network interface card, eth0: – Interface: eth0 IP Address: 172.16.0.1 Netmask: 255.255.255.0 Gateway: 172.16.0.254 We need to add two static routes below and these routes don’t route to the default route of eth0 interface, 172.16.0.254: – Interface: eth0 Address: 192.168.1.0 Netmask: 255.255.255.0 Gateway: 172.16.0.11 Interface: eth0 Address: 10.20.30.0 Netmask: 255.255.255.0 Gateway: 172.16.0.12 Here is how we can do it by creating this /etc/sysconfig/networkscripts/routeeth0 file. You have two ways to define the content. I had tested on CentOS 5.9 and 6.4 version and it works. Option 1, include the below in /etc/sysconfig/networkscripts/routeeth0 file: – GATEWAY0=172.16.0.11 NETMASK0=255.255.255.0 ADDRESS0=192.168.1.0 GATEWAY1=172.16.0.12 NETMASK1=255.255.255.0 ADDRESS1=10.20.30.0 Option 2, include the below in /etc/sysconfig/networkscripts/routeeth0 file: –
