[c-nsp] Filtering Routes with Private AS Numbers in the AS Path

[Ivan]

Hi Nick,

Thanks very much for your thorough response and the time your put into 
testing things out.  I was contemplating taking this to my lab but was 
hoping there was some documentation or experiences from others that may 
have helped answer things first.

Your results are interesting - I did suspect option 2 would be better 
but didn't really have any idea of the numbers.  Saving time and 
processing cycles on BGP routes is always good.

Interesting to see just how may routes with private AS number in their 
paths are out there in the DFZ too.

Thanks

Ivan
