Most of my customers have customers who in turn have customers, not a few of
whom are multi-homed.  Same for UUNET, ...

So, at POP X, I take in maybe 100 prefixes, with maybe 1000 at some POPs.
How do I build and maintain that filter list, and how long does it take each
packet to get through it with a router that also does real routing?
