Network Design

Enterprise XYZ wants to implement fast network convergence and optimize OSPF timers. However, it also wants to avoid excessive LSA flooding when a link in the network is continually flapping. Which OSPF timers can help prevent excessive LSA flooding?

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

OSPF LSA throttling timers rate-limit repeated LSA generation and dynamically slow LSA updates during network instability, such as a continuously flapping link. This preserves fast convergence for initial changes while reducing excessive LSA flooding.
