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

  I don't 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.
