Brian,
it is simply amazing how u guys really helped many of us out here, while i
figured i'll sell off my r&s lab to get some extra cash to throw in some
high powered PCs to run dynamips, u've got us covered with the dynamips
scripts.
Thanks & anxiously awaiting for the release of ur SP book.
kenny
