Fresh install with 2 ip address on linode

I am about to install Centmin on a new linode server. I have two IP addresses. Is there a way to setup both IP addresses during the initial install or do I have to manually install the second IP after the install?

If the latter, according to the documentation, the setup in ifcfg-eth0 (CentOS 7 only) would be:

DEVICE=eth0
BOOTPROTO=static
IPADDR0=192.168.2.1 <= first IP addresses
IPADDR1=192.168.2.2 <= 2nd IP addresses
NETMASK=255.255.255.255
BROADCAST=xxx.xxx.xxx.xxx
ONBOOT=yes

The problem is that on my current linode server (CentOS7 with latest centimod) the ifcfg-eth0 config file has a different format. Below are the relevant parts.

DEVICE="eth0"
NAME="eth0"
ONBOOT="yes"

BOOTPROTO="none"
DOMAIN=members.linode.com
GATEWAY0=xxx.xxx.xx.x

DIPADDR0=xxx.xxx.xx.xxx

PREFIX0=24

---

How would I go about adding the 2nd address? Do I just add the second IP and Gateway to additional variables GATEWAY1 and DIPADDR1? How about PREFIX0?

Thanks for the help.

 

Looks like I am treading on uncharted territory! I will submit a ticket and post my findings.
