I've been bit by this in the past at two different exchanges. I too have a policy applied to deny IXP LANs from upstreams and peers. It would be nice if there was a list of all IXP LANs somewhere that we could generically add to all upstream and peers.
I like Nick Hilliard's posted solution much better than creating static bogon lists that people will eventually forget about.
