A GRE tunnel between R1 and R2 has been configured over an Internet connection. As soon as
traffic is sent over the tunnel, high CPU utilization is observed on R1. Reducing the traffic shows a
reduction in CPU utilization. What could be a possible cause for the high CPU utilization?

Refer to the exhibit.

You are investigating connectivity issues on your LAN and have noticed that sometimes you
