But ifcfg-eth0 file only support one IP even you write multi IPs in the file and I do not want to interface alias which mean add another IP in ifcfg-eth0:1 file because this way is same use ipconfig to add another IP on same NIC. How to only configure the ifcfg-eth0 file can let OS automatically add two IPs on one interface when OS start up?
