There's significant theoretical work, backed up with lots of practical experience connecting a lot more nodes in real time in a lot more places than the Internet currently does, that posits that the control and forwarding plane should actually ALWAYS be separate, and control higher priority, so that state management converges faster than the dataflows.
I'd like to see the countervailing, peer reviewed, references.
I have no shortage of anecdotes where a non-trivial layer-2 topology at an exchange point has left my router and provider X's router both able to talk to a route server, but unable to talk to each other directly. Since the NEXT_HOP on routes we each learnt from the route server pointed at an address we couldn't talk to, the result was a black hole. So while your theoretical work might well have substantial merit, its application to the example at hand seems potentially lacking. I am somewhat intrigued at this network you mention with which people have practical experience that has more nodes than the Internet does, though. That'd be quite a network. Joe
