I think it does look for host routes before matching network routes, but
there needs to be one in your routing table. I believe when you configure
the interface the driver installs the network route only. i.e. by default
they will clash.

Yes, I believe you need to explicitly add them to the routing tables.

You are correct, but you have to set it up manually. Or maybe it depends on
what net-tools package you use - the one I use doesn't add the host routes.

What could be more simple than removing all that really complicated IP
protocol overhead? :-) Cheers!
