Other than that, Mrs. Lincoln, how was the play? ;-) The advantage to that behavior is that it helps reduce the state involved. If all iBGP speakers advertise all routes, then you end up with tables the size of (# of routes) * (# of BGP speakers) at every speaker. While this might not seem like a lot, consider the case of Tier 1 SPs who have 240k routes (+ internal routes) times 500 or so BGP speakers. DRAM is cheap, but it's not free.
