I think this would work with the changes in the script you sent before
(except maybe setting up the routes). Assuming the ALIAS or LABEL
option is added to ipv4-static, you'd just have 3 conf files in

IP=<first IP>
GATEWAY=<first gateway>
PREFIX=<first subnet prefix>
BROADCAST=<first broadcast>

IP=<second IP>
ALIAS=<first alias>
GATEWAY=<second gateway>
PREFIX=<second subnet prefix>
BROADCAST=<second broadcast>

IP=<third IP>
ALIAS=<second alias>
GATEWAY=<third gateway>
PREFIX=<third subnet prefix>
BROADCAST=<third broadcast>

And, of course, you could name the files something far more
descriptive so that you knew which subnet you're referring to.
However, if he's referring to adding more routes with support for
aliases, then that support would probably need to be added to
ipv4-static-route, too. That would be trivial, though, and probably
should be done if ipv4-alias isn't a separate script.
