CCDE: Cisco Certified Design Expert (Practical) — Question 144

A BGP route reflector in the network is taking longer than expected to converge during large network changes. Troubleshooting shows that the router cannot handle all the TCP acknowledgements during route updates. Which action can be performed to tune the device performance?

Answer options

• A. Decrease the size of the small buffers.
• B. Increase the size of the large buffers.
• C. Increase the keepalive timers for each BGP neighbor.
• D. Increase the size of the hold queue.

Correct answer: D

Explanation

Increasing the size of the hold queue allows the router to manage more incoming packets before processing them, which can help in handling the TCP acknowledgements effectively during route updates. The other options either reduce buffer capacities or adjust timers, which would not address the main issue of processing capacity during high traffic loads.
