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: > > 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? > Donate cash, emergency relief information > http://dailynews.yahoo.com/fc/US/Emergency_Information/ begin:vcard n:McGaugh;David tel;fax:360.816.3297 tel;work:360.816.3718 x-mozilla-html:FALSE url:http://www.eli.net org:Electric Lightwave, Inc.;Network Planning and Engineering adr:;;4400 NE 77th Ave.;Vancouver;WA;98662;USA version:2.1 email;internet:[email protected] title:Internetwork Engineer x-mozilla-cpt:;26448 fn:David McGaugh end:vcard
