That would be very interesting. I am always leery of vendor models as they tend to have the vendor foremost in their mind :-) I always try and caution folks not too build hierarchy just to have it. Naturally, your 15 router OSPF network's visio diagram exudes a great deal more sharpness when it has a nice backbone and some number of non-backbone areas. However, in reality, many networks -large and small- are served far better with non hierarchical topologies. I am naturally digressing from the topic of three layer networks, but I think the message is the same. As others have pointed out, don't give in to the desire to build really neat networks that use a lot of technology unless you actually have a need for them. This to me would include building 3 layer networks where 2 layer ones would suffice (and be cheaper in both CAPEX and OPEX) Just my .02c as I sit here snowed-in in Arkansas of all places :-) Who would think I'd fly from Toronto to Littlerock and end up stuck in more snow than I left!
