Designing Cisco Enterprise Networks (ENSLD) — Question 10

Which two steps can be taken to improve convergence in an OSPF network? (Choose two.)

Answer options

• A. Use Bidirectional Forwarding Detection
• B. Merge all the areas into one backbone area
• C. Tune OSPF parameters
• D. Make all non-backbone areas stub areas
• E. Span the same IP network across multiple areas.

Correct answer: A, C

Explanation

Using Bidirectional Forwarding Detection (BFD) helps in quickly detecting failures in the path, thus improving convergence. Tuning OSPF parameters allows for better optimization of routing protocols, enhancing the overall performance. Other options, like merging areas or making all non-backbone areas stub, may not necessarily lead to improved convergence and could complicate the network design.
