Sorry to resurrect an old thread, but I'm also confused on this
ASR1001 FIB question.

The Cisco ASR 1000 ESP data sheet
(http://www.cisco.com/en/US/prod/collateral/routers/ps9343/data_sheet_c78-450070.html)
lists the ASR1001 separately from the ASR1002-5G.  It claims the
ASR1001 does 1M IPv4 and 1M IPv6 routes.  (Not to be confused with the
numbers on the ASR 1000 RP data sheet, which say it can do up to 9M
with 8GB RAM doing selective download.)

Does anyone have a link to a definitive document clearly showing FIB
numbers for the ASR1001?  I've got an email into our Cisco SE, but I
don't think they're motivated to sell us a lower-end box. :-)
