I saw an output someone pasted to me from a Sup2T indicating it would take 
1M IPv4 routes and 0.5M IPv6 routes (at the same time). I don't have 
access to one myself so I can't verify.

The major issue with Sup720 is that it's slow and I've seen them fall over 
and start losing other adjacancies when there was a lot of BGP work.
