                One way to get lots of routes showing up in a host is to be on
        an Ethernet with several gateways that are connected to different
        regional or backbone networks. If you want to do robust routing, your
        host needs a route to each reachable net and that number is getting
        pretty large today.

This is not a requirement for "robust routing." An Internet host should
only need to know a few default gateways, and take Redirects to find out
about the others. This is just another example why hosts wiretapping
gateway IGP's is not a part of the Internet architecture, and is
often a bad idea.
