I guess the answer is pretty much not. The amount of interior routing information in a properly designed backbone is quite small even if there is no two-layer abstraction. (Now, the _exterior_ information is aplenty, but OSPF is useless for it anyway). If someone proposed simplifying and cleaning up OSPF i'd be quite for it. Building a protocol allowing to get rid of iBGP hack would also help :) --vadim
