It's a standard 6500 with SUP720-3BXL and SXI3 IOS CPU when things are stable - meaning no 300k prefixes are received and handled by a route-map: CPU utilization for five seconds: 5%/3%; one minute: 8%; five minutes: 22% PID Runtime(ms) Invoked uSecs 5Sec 1Min 5Min TTY Process 442 32752540 23050084 1420 1.67% 1.83% 3.58% 0 BGP Router 12 10530960 73568808 143 0.23% 0.32% 0.43% 0 ARP Input 24 9929364 66536895 149 0.15% 0.15% 0.12% 0 IPC Seat Manager 550 5590548 104678906 53 0.07% 0.12% 0.17% 0 IPv6 Input 9 35321344 1775168 19897 0.00% 1.81% 1.61% 0 Check heaps 52 1741276 44845 38828 0.00% 0.04% 0.05% 0 Per-minute Jobs 267 2372 2128 1114 0.00% 0.11% 0.02% 1 SSH Process 273 6081996 48117818 126 0.00% 0.12% 5.80% 0 IP Input 328 5130588 41932 122354 0.00% 0.13% 0.16% 0 IP Background 329 1397596 2073628 673 0.00% 0.03% 0.06% 0 IP RIB Update 353 825140 3638618 226 0.00% 0.02% 0.03% 0 CEF: IPv4 proces 403 8109668 2461860 3294 0.00% 0.04% 0.16% 0 BGP Scheduler 493 626732 4529700 138 0.00% 0.04% 0.02% 0 Port manager per 553 2499400 19689788 126 0.00% 0.08% 0.17% 0 BGP I/O 557 1455124 3184221 456 0.00% 0.06% 0.03% 0 SNMP ENGINE 563 58994480 455252 129587 0.00% 1.66% 2.41% 0 BGP Scanner > > A few things to check in general which could have impact on BGP > performance: > - Do you have BGP Path MTU Discovery enabled?

I currently have no COPP at all. But I can assure that the router is not under any sort of attack. It's always behaving like that when a larger peer (full table) is sending me prefixes. And right now the whole mess does not want to stabilize - sometimes it does after 30 minutes, sometimes it takes forever.
