[c-nsp] asr1001 4 full bgp feed

[Chris Balmain]

Hi,

ASR1001 can hold 1,000,000 routes in the FIB if you have 8GB memory. See 
table 4: 
http://www.cisco.com/en/US/prod/collateral/routers/ps9343/data_sheet_c78-441072.html

We have an 8GB unit taking two full feeds and a couple of IXes (another 
~10k prefixes), memory usage is approximately 1.2G of the 4G that is 
available to IOSd.

Given the relentless growth of the global v4 table, I wouldn't feel 
comfortable with a FIB capability of 512K. How long do you think that'll 
suffice?
