IP Failover configuration

Guide to configure IP Failover on CentOS server in ovh farm.
nano /etc/sysconfig/network-scripts/ifcfg-eth0:0
Copy and paste this code:
DEVICE="eth0:0"
BOOTPROTO=static
IPADDR="IP.FAIL.OVER"
NETMASK="255.255.255.255"
BROADCAST="IP.FAIL.OVER"
ONBOOT=yes

IP.FAIL.OVER is ip number of your IP Failover. Now set new interface and reboot server:
ifup eth0:0
/sbin/reboot

When server restarted ping IP.FAIL.OVER:
ping IP.FAIL.OVER
If you have more IP Failover, set eth0:1, eth0:2, ..
