Re: Determine difference between 2 BGP feeds

More than likely, one provider is feeding too many routes -- some that I 
have run across tend to feed more specific internal routes (read: 
redistributing IGP into BGP) to customer BGP sessions.

The two I've run across, after I yelled, they fixed.

        I quickly took a look for anything less than a /24 (Not that you
can't route /24s in IGP) and that accounts for 25% of the overage :

/25 - 274
/26 - 178
/27 - 165
/28 - 123
/29 - 114
/30 - 116
/32 - 47

        Continuing to see what I get...
