Alcatel-Lucent NRS I – Layer 2 Switching and Spanning Tree — Question 20

Which of the following statements regarding BGP control plane convergence is FALSE?

Answer options

• A. Core and edge node failure recovery depends on IGP convergence.
• B. Edge neighbor failure is detected by the eBGP session timeout.
• C. BGP control plane convergence is independent of number of affected prefixes.
• D. Upon BGP control plane convergence, an optimal path is installed in the FIB.

Correct answer: C

Explanation

The correct answer is C because BGP control plane convergence is indeed influenced by the number of affected prefixes; a higher number can lead to longer convergence times. Options A, B, and D are true as they accurately describe the relationships between IGP convergence, eBGP session timeouts, and FIB updates during BGP convergence.
