Troubleshooting Route Processor Route Table and Utilization Problems
Step 3 Scan down the process list to identify which process is contributing to the 75% CPU process utilization.
From this example of EIGRP convergence, you can see that the IP- EIGRP Router process is accounting
for 66.72% of the 75% CPU process utilization. Use this same process to identify other processes.
Step 4 Use the show ip traffic command to check whether the packets sent to the route processor are being
processed.
