CCDE: Cisco Certified Design Expert (Practical) — Question 205

Enterprise XYZ wants to implement fast convergence on their network and optimize timers for OSPF. However, they also want to prevent excess flooding of LSAs if there is a constantly flapping link on the network. Which timers can help prevent excess flooding of LSAs for OSPF?

Answer options

• A. OSPF flooding timers
• B. OSPF delay timers
• C. OSPF propagation timers
• D. OSPF throttling timers

Correct answer: D

Explanation

The correct answer is D, OSPF throttling timers, as they specifically help limit the number of LSAs sent during link flaps, preventing unnecessary flooding. The other options do not directly address the issue of LSA flooding during constant link changes, thus making them less suitable for the scenario described.
