It's just a development platform for prototyping designs, not
something you would use in production...
I want to use it to implement and test ideas that I have, and play
with some different forwarding architectures, not use it as a final
product :)

also, does a datacenter router/switch need a full table? isn't that
the job of the peering/transit routers in your scheme?


Sometimes, but often you get odd results when internal gateway routers only see a pair of default gateways via OSPF or 
IS-IS. Sometimes the only real fix is to have a full table on these routers as well as your border/peering routers.
