But the ESP5 isn't modular. It is a fixed ESP in the ASR1002 
and ASR1001. I confirmed with our SE a while back - the 
documentation on those tables is somewhat misleading. The 
ASR1001 has always only had support for 512,000 v4 entries 
in the FIB.

That said, the ASR1001 ships with a 2.5Gbps ESP by default. 
But this can be upgraded to 5Gbps with a software key. There 
is no indication that the software key upgrade also 
increases FIB capacity.

Also, ESP5's are only on the ASR1001 and ASR1002 systems, 
which are both fixed chassis, i.e., you can't run an ESP5 on 
the ASR1004, ASR1006 or ASR1013, which are all modular 
platforms.
