CCR2004 real routing performance?

Tue Jun 22, 2021 4:24 am

Hi guys,
I have watched a video on YouTube showing that the CCR2004 with LACP is unable to route more than 9 Gbps of traffic. I would like to know if there's someone that has tested the routing performance with LACP, and have confirmed if performance is really that limited :'(

Best regards

Official test results have many numbers in the table, ranging anything between 600 Mbps and 40 Gbps. Which means that routing performance very much depends on particular configuration. It's hard to tell how much LACP hits performance unless one performs two tests with LACP being the only difference.

The test result table indicates, that when one configures some firewall rules (real life scenario in most SOHO cases, perhaps not when used in carrier / ISP environment) routing performance drops to around 5 Gbps give or take.

CCR2004 has hardware problem: reboot, port flapping and packets loss please stay away from it

Had an incident with a client of mine recently where they peer with a Internet Exchange at data centre routing +- 200Mb/s on a 2004.

The Internet Exchange route server sends constant route updates in BGP which causes the 2004 CPU to spike to 30% utilization every +- 45 seconds, when this happen, any traffic routing through this 2004 device experienced either a huge jump in latency or packet loss

Disabling firewall connection tracking, etc did not make any difference
