Re: slowing down every 60 seconds due to BGP scaner

I said nothing about pings. The router is freezing (or at least slowing a lot) every 67.5 +- 3 seconds. We this for both inbound and outbound - outbound things are buffered but inbound they seem to be lost.

What kind of NPE, how much memory, how many BGP views, what interfaces, and is there a particular reason that you're running 12.2? ---rob
Cisco said this is normal? Normal default operation maybe. The default BGP scan time is 60 seconds. This can be modified with the "bgp scan time N" command. That's not a production router, is it? (T) code is test code. That's the first code with IPv6 and MPLS Label Distribution Protocol support. Not the type of stuff you'd want to be running on your backbone (unless you needed some functionality that it introduced). Sincerely, Dennis J.

That + what else running on the router vesides BGP, is it a 7204VXR? maybe just copy the output of "show hardware"
and is there a particular reason that you're running 12.2?

It's actually 12.2 "T" series and 12.2(2)T was the first FCS - not exactly a good idea for a production .. ( see <http://www.cisco.com/warp/public/770/index.shtml?60,8> for "Cisco IOS 12.2 and 12.2T Release Numbering Changes" Do you need IPv6 with "official" support ? why the "T" series ? If you really _must_ use 12.2T are you having problems with BGP next hop? then try checking bug _CSCdu74704_ - supposedly fixed in IOS 12.2(2)T02 --- A Cisco 7200 or 7500 series router that is running Cisco IOS Release 12.2(2)T may experience high CPU utilization for a "BGP Router" process if the router is configured for eBGP peering and the next hop becomes unreachable (for example, when an interface to an external peer is shut down). High CPU utilization occurs only if the router must send a large number of withdrawn routes to other peers because the next hop is unreachable. There is no workaround. - Rafi
