slowing down every 60 seconds due to BGP scaner

[tang bing <tang_bing () yahoo com>]

Hi, 
I found all of my backbone routers slow down every 60
seconds , it will last 5 seconds .
While this happens , the CPU may get more than 70%
utilization and BGP scaner is the process that chewing
the CPU (50%) .
Customer with video stream noticed that .
Cisco said it's normal .Any idea ?
Thanks you !

Ben
