Linux: how to configure a secondary IP address upon boot-up?
Normally what you would do is create a alias so you would have one IP bound to eth2 and one bound to eth2:1
You would configure your startup scripts as such
/etc/sysconfig/network-scripts/ifcfg-eth2
DEVICE=eth2
IPADDR=65.130.27.69
ONBOOT=yes
BOOTPROTO=static
BROADCAST= ... etc, etc.
/etc/sysconfig/network-scripts/ifcfg-eth2:1
DEVICE=eth2:1
IPADDR=65.130.27.70
ONBOOT=yes
BOOTPROTO=static
BROADCAST= ... etc, etc.
