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.
