CCDE: Cisco Certified Design Expert (Practical) — Question 93

Company XYZ was not satisfied with the reconvergence time OSPF is taking. BFD was implemented to try to reduce the reconvergence time, but the network is still experiencing delays when having to reconverge. Which technology will improve the design?

Answer options

• A. OSPF fast hellos
• B. BFD echo
• C. Change the protocol to BGP
• D. Change the OSPF hello and dead intervals

Correct answer: B

Explanation

The correct answer is BFD echo, which can help reduce the time taken to detect link failures and improve overall network responsiveness. OSPF fast hellos (A) and changing OSPF hello and dead intervals (D) may help, but they do not leverage the benefits of BFD effectively. Changing the protocol to BGP (C) is unrelated to the issue at hand and would not resolve the OSPF reconvergence delays.
