There is nothing inherently good or bad about switches either. The problem comes in, as Sean stated far more eloquently than I can, when layer 2 and layer 3 each have their own intelligence and do not work together. This is probably the single most problematic part of the layer 2 + layer 3 designs I've seen implemented. While this has in large part caused by the lack of correct tools to build such a beast, when you are trying to tie a necktie with two hands and your left and right hands don't coordinate, you sometime end up hanging yourself instead. -dorian
