<div dir="ltr">To do "VIPs" on linux where the box is doing something behind a load balancer then I think you may want to add the IP as a loopback via 'ip addr add'. I'm not actually 100% sure what the best thing to do on rhel is though.

alias IPs (along with the primary IP) had to be configured in the main ifcfg-eth0 file in /etc/sysconfig/network-scripts rather than in a separate ifcfg-eth0:1 file as they did previously. In RHEL6 we disabled Network Manager to return to previous functionality
mainly because we couldn’t see the aliases with the old tool (there was a newer one to see them but it annoyed others).<u></u><u></u></span></p>
