Anyone out there connect to an ISP peering point (exchange, MAE, whatever)?
I'm interested in what you do to avoid crappy BGP routes. Anyone have
experience with rtConfig, either good or bad?

Not to mention any specifics... but I believe the above sort of thing is
correct. The routes exchanged are run through a filter to remove crap.
where crap can be invalid routes (bogons), routes for prefixes that
are too long (or short), and routes that violate a given policy.
Then there are all sort of other fudges, like manipulating the path
you receive from, or supply to a given peer (i.e. inserting/removing ASNs).
