sure. This assumes a 100% coverage for all inputs to the rib-out on the customer port we're talking about, though. If you don't have 100% coverage you'll end up with the leaks seen/reported by the OP. I don't mean to say/imply: "Hey, everyone(anyone) should do OV on output" I mean to say that: "Hey, if you see OV failures leaking, this is probably a side effect of the behavior/design choices a network made." (not doing OV filtering on one of peer/customer/transit type peerings." -chris
