IRR-clueful person at 3356?

Hi folks, Sorry for the extremely broad email but I'm trying to sort out an IRR issue regarding automatic filter generation at Level(3) on behalf of a friend. The telemetry I'm getting (thirdhand and believed to originate from first line support) suggests that both Level(3)'s direct customer and any downstreams of that customer need to be in the same IRR component. If true this would be a rather startling shortcoming of their filter generation software and at odds with the whole point of having multiple components to the IRR system. Anyone got any pointers or help? Email to rr@level3.net has not gotten us anywhere, but I was not the one who sent it and can't guarantee that the right questions were asked. Thanks, -r
