For us who actually have customers we care about, we probably find it better for business to try to make sure our own customers can't announce prefixes they don't own, but accept basically anything from the world that isn't ours.You are a distinct minority. My experience has shown that most ISPs don't give a sh*t about filtering what their customers can announce so what has happened, will continue to happen.
I've only dealt with a handful of the bigger networks, but every transit BGP session I've ever been the customer role on has been filtered by the provider. From memory and in no particular order, that's UUNet, Level3, Digex, Intermedia, Global Crossing, Genuity, Sprint, Above.net, Time Warner, C&W, MCI, XO, Broadwing, and a few smaller ones nobody's likely to have heard of.
As an ISP providing transit, all of our customers get prefix-filtered. ---------------------------------------------------------------------- Jon Lewis | I route Senior Network Engineer | therefore you are Atlantic Net | _________ http://www.lewis.org/~jlewis/pgp for PGP public key_________
