Unfortunate... but the "fake" "foo:X" interfaces has been deprecated for I guess soon almost 20 years now. It's not a real interface and there's absolutely no reason to use that syntax with ip(route2). The iproute2 suite has been designed from the start to properly handle multiple ip-addresses on the same interface. You can add and remove addresses on the fly as you go. No need to bring up extra fake interfaces for that. You should really stop using that syntax and any software who still relies on the syntax (and screen-scraping the output of tools rather than using the netlink interface) is likely quite out of date so you should probably consider moving to a more modern alternative.
