case, you shouldn't see any valid ICMP redirects. They're there mostly so
things kind-of-sort-of work even if you botch it (so for instance, even if
you whiff your default route accidentally, you can still ssh in from Tokyo and
fix > it).
For ICMP redirects to do anything useful, a valid route has to
actually be there already, on the default gateway....
Perhaps you are thinking of proxy arp? :)
