Keep in mind, on that platform, IPv4 and IPv6 routes share (rob from each 
other) space.  1mil IPv4 routes assumes you're not doing IPv6 at all. 
More realistic is some kind of split.  i.e.

L3 Forwarding Resources
              FIB TCAM usage:                     Total        Used       %Used
                   72 bits (IPv4, MPLS, EoM)     622592      281799         45%
                  144 bits (IP mcast, IPv6)      212992         263          1%

You can tune the split...but it requires a reboot.
