After we prove the CPU utilization can be easily increased by anyone anytime (as shown in the previous blog post, “Protect the Control Plane – part 1, trivial attack.”), I feel obliged to show how to quickly prevent the cause of potential network and services damage.

Control Plane Protection – part 1, trivial attack.

How many of you use the control plane protection features given by the vendor with the benefit of inventory? From what I see mostly, it is a very rare practice to use CoPP. Most of the network engineers haven’t even heard of it. “Because my network performs well, why should I care about control plane […]
