Also, router CPU's were much slower then than they are now. The IGP's have gotten a little more complex also, but by-and-large, are still the same if you don't do "fancy things". So there would be a certain amount of increase in scale that an IGP domain would support, perhaps, regardless of which IGP is chosen. Mark.
