slowing down every 60 seconds due to BGP scaner
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 __________________________________________________ Terrorist Attacks on U.S. - How can you help?

We've brought this concern up to Cisco before and they assured us that everything is performing normally. You will see this when performing router to router pings as well however, we have been told that packet forwarding does not suffer. ICMP replies from the router (not through the router) are given a very low CPU priority. -Dave tang bing wrote:

We see this every 67.5 seconds on average; utilization goes to about 99.9%. Oddly, it seems to have started this summer. Were are currently running Version 12.2(2)T1. -- Regards Marshall Eubanks T.M.
