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. Bob Braden
