  Randy, would you like to explain to us what your criteria are ?
 How many routers, links, prefixes should one be able to put in one IGP ?
 How many in one area ?
 How much dynamics should an IGP be able to endure ?
 How much optimal routing are you willing to give up by using summaries
 to improve scalability ?
 Do you think it is acceptable to tune the IGP by user configuration (like
 laying out areas), or should the IGP be full-automatic ?

     Thanks in advance,

         Henk.
