Yes, the presence of 'no ip classless' (or ip clueless as I like to call
it) can have an effect. For the purposes of our discussion I was
assuming ip classless. Assuming 'no ip classless' needlessly muddies
the waters, in my opinion.
However, point taken. We all should be aware of the difference in
classfull and classless lookups. then, always use classless routing and
forget out about it. ;-)

John,
Considering the question ip forwarding varies if you are deling with
classful or classless addressing.
