Good points Matt. We used to say around 30-40 routers per area but that
doesn't apply any longer in newer code, in a point-to-point environment
anyway. In fact, if you're a hub / spoke with point-to-point connections you
can do over 100 routers in an area. Again, that goes back to Matt's point
about "it depends", there is no set value and we would naturally have to quote
the lowest common-denominator for all customers.
