Hi folks, I'm facing an odd issue causing high CPU load on a Jetcore BI4K, with for what seems to be caused in a ip transit uplink.
We are running BGP on multiple jetcore BigIrons. Now there are 3 border routers which each have an ip transit uplink. After some time (a day or sometimes more like a week) we see a high CPU load and it doesn't stop until we shutdown the BGP session with one of these carriers. So far we have seen 2 crashes which may have been caused by this. So we moved that carrier to a different router (same model), replaced the used SFP, upgraded the software on the router but nothing solves the problem. Also our carrier relocated the port to a complete different switch and router, but still no luck. My carrier double checked everything over and over and with their reputation it's most unlikely they would be failing here. Now the load is on IP level when issuing a 'sh proc cpu' command and NOT on the BGP level. I hope someone somehow has ever seen a situation alike and found the issue, or maybe has some recommendations on how to debug this. Maybe someone knows any additional configuration that may help me out here. The concerned config is: ! vlan 20 name TRANSIT-BGP by port untagged ethe 1/1 router-interface ve 20 ! interface ethernet 1/1 route-only no spanning-tree sflow forwarding ! interface ve 20 ip address ???.???.???.??? 255.255.255.252 no ip redirect ip arp-age 120 ! Thanks in advance for any help and efforts! Kind regards, Bardo Cornelissen.
