So Provider A announces his ten /15 CIDR blocks to Provider B, aggregating
huge numbers of IPs into those ten announcements. He then wishes to
announce 20 "bad" prefixes from customers of /21 or longer. Under your
plan, that doesn't fly. Why is it that we assume that a "large" provider
has to be announcing many routes?
