IIRC, the specs for the Sup2T make the same max routes claim as the 
Sup720-3BXL (i.e. 1000000 IPv4 routes, 500000 IPv6 routes, which for the 
3BXL is misleading at best).  Is the IPv4/IPv6 routing split still the 
same on the Sup2T, where you can have 1M IPv4 routes with IPv6 turned off, 
or some split such as:

[from show platform hardware capacity]
L3 Forwarding Resources
              FIB TCAM usage:                     Total        Used       %Used
                   72 bits (IPv4, MPLS, EoM)     622592      368412         59%
                  144 bits (IP mcast, IPv6)      212992        7041          3%

As IPv4 runs out, I suspect we're going to see continued, if not 
explosive, IPv4 routing table growth, and I'll be very disappointed if 
cisco didn't engineer the Sup2T to support more routes than all previous 
models.  If not, hopefully there's some more capable PFC/DFC on the way, 
or maybe cisco just wants to eventually stop people from using the 6500 
platform as a full BGP router and sell more ASRs or something.
