I guess I see why it works but why would it EVER be configured this way?
Configuring "ip route 0.0.0.0 0.0.0.0 E0/0" is so the router will treat all
of the destinations that the router does not know how to reach through some
other route(in the routing table) as directly connected to E0/0. So the
router should send an ARP request for each host that it receives packets for
on this network segment? I would think that this would kill a router! The
arp tables would be huge! Am I off on this? Like I said, I'm probably making
this a bigger deal then it really is but if there are good design strategies
that I'm not taking advantage of, I WANT TO KNOW!!! If I were a proctor, and
my thoughts are somewhat close, I would take points off for bad design :)
