Don't expect an ASR1001 to be able to handle a full routing table within 
the next two years.  They have enough space on the ESP to handle only 500k 
ipv4 prefixes (or 125k ipv6), and it is highly likely that with the 
expected growth of ipv6, that this memory will be exceeded before too long. 
  Bear in mind that on these boxes, a single ipv6 prefix takes up as much 
lookup memory as four ipv4 addresses.

If you need to do full routing and want to do it on the ASR1k (which is a 
really nice platform, btw), then you should look at an ASR1002 + ESP10 or 
larger (which will handle 1.7M ipv4 / 500k ipv6 prefixes).

Otherwise yeah - the ASR1k platform is a huge improvement on the 7300 / 
NPE-G2 line.
