BGP analyzing tool

Tue Nov 21 14:27:20 UTC 2006

Hi,
   Are there any available BGP analyzing tool that can be used to identify 
details on best chosen path based on the BGP algorithm? NTOP can capture the 
traffic info, but to analyze each destination to find the reason for selection 
(local preference, no of AS hops, iBGP vs eBGP etc) would be hard. I need this 
info to understand why a certain upstream is being more prefered than the 
others. Thanks.

Regards,
Kana
