Which is a good thing too, since, as we do closest-exit routing towards InternetMCI, whether we hear one prefix in your /14 or 10000, packets will go out the same direction under normal circumstances. Anyone wanting to deal with abnormal circumstances (partitioning of InternetMCI that makes part of a big aggregate unreachable from a border gateway announcing the entire aggregate) is welcomed to study Yakov Rekhter's excellent presentation on the "push" operation. Anyone downstream from us wanting to route differently towards different parts of the big aggregate is welcomed to study Yakov Rekhter's excellent presentation on the "pull" operation.
