So it does not make sense for IBM or Sony to run dynamic routing in their internal networks?!?
That depends. If the topology can change then you probably want dynamic routing. Usually when I set up a Sony-sized IGP, I run dynamic in the core and use statics to reach the edges, since while there are usually backup paths in the core, the edges tend to be singly connected. This is identical to the reasoning I'd use if I were designing an NSP. That's what was meant by:
Why? What we have been arguing for has been limiting the scope of dynamic routing only to places where participating in global dynamic routing makes sense.
