Hi Doug,
             How about cisco? In juniper, 'show route detail' really helps. Thanks.

I donít know of any tool, but it seems like you should be able to get a show route detail about, write a script to choose inactive reasons and sort based off that.

Using cli like "sh ip bgp xxx.xxx.xxx.xxx"[Cisco] or "sh route protocol bgp xxx.xxx.xxx.xxx detail" [Juniper] would be able to show me details for specific destinations. What i need is a software to get all the data from a routers routing table, analyze the best path and summarize the reason why its being chosen based on the BGP algorithm (local pref, no. of hops, MED, etc). That would show the big picture of why a certain upstream is more prefered than the other. Thanks.

What kind of router?  A juniper will show you this with a show route detail.

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.
