My opinion is it defaults the purpose of the exercise is because you have
to rely on the floating static route so you're really not using EIGRP at
that point. You do not need to do that with OSPF, the routes aren't
flushed if you use ip ospf demand-circuit.
But since we're all beating a dead horse I guess we'll just have to agree
that we disagree... ;-)
