HPE7-A08 · Question #195
After configuring BFD for OSPF you are receiving monitoring alerts for high CPU utilization on your switches. Based on the configuration below, how should you resolve the issue?
The correct answer is C. Enable BFD echo mode. BFD in normal asynchronous mode sends control packets at regular intervals, which can increase CPU load on busy switches. Enabling BFD echo mode offloads much of the processing to the data plane by using the forwarding ASIC for rapid detection, significantly reducing CPU…
