Then this is just two instances of the same problem: You have a site with a /24 and multiple upstreams. How do you aggregate?It doesn't have just one path.

Answer: You don't. This is the type of deaggregation which is a "necessary evil". And, IMHO, why filtering on /20 (or whatever) is a Bad Thing. You have just as much right to multiple upstreams as the "big guys". Again, IMHO. Many people on this list - all of them running large networks, you will notice - would argue otherwise. They seem to think that if you do not have a /16, you should not have multiple upstreams.
Fortunately, the market, and the Internet, has clearly spoken. Unfortunately, they may have spoken a little too loudly, and now we have "/24s run amuck". :)
