oh bummer ;( that's not us sending that is it? :) Honestly, prefix
filtering should apply in both directions. You'd want to be sure that your
upstream didn't send you 1918 prefixes, or bogons or even your internal
infrastructure, eh?

hopefully a simple prefix filter as in the one mentioned a few times from
cymru would fix it for you :)
