Isn't it true though that some upstream providers (such as Sprint) filter
out anything smaller than /19 and will not carry those routes? Therefore
in this example, Sprint clients would not be able to see these smaller
providers and vice versa unless he agregates them to /19 or higher and
then announces the routes himself?
