This is not quite true.  The ASR1001 has a FIB limit of 512k ipv4 prefixes
(non upgradable).  However, if you're using the ASR1001 purely as a route
server you don't need to install all prefixes in the FIB.  You can signal
this by using the "table-map <route-map-name> filter" command, which stops
rib->fib export and speeds up RR operation in the process.
