                                          NEW QUESTION # 169
                                          A company with multiple service providers wants to speed up BGP convergence time in the event a failure occurs with their primary link. Which approach achieves this goal and does not impact router CPU utilization?

                                          Answer: B

                                          Explanation:
                                          BFD with default BGP timers is the best design choice because it improves failure detection without forcing BGP itself to run aggressive keepalive processing. Cisco documentation describes BFD as providing fast forwarding-path failure detection and notes that BFD can be less CPU-intensive than reduced EIGRP, BGP, and OSPF timers because parts of BFD can be distributed to the data plane. Lowering BGP keepalive and hold timers makes the BGP process detect failure sooner, but it increases control-plane activity and can create instability at scale. Tuning the BFD multiplier to an extreme value such as 50 is also counterproductive because it lengthens detection rather than improving it, depending on the interval used. The correct approach is to leave normal BGP timers in place and bind BGP neighbor fall-over to BFD. When the forwarding path fails, BFD notifies BGP quickly, allowing the route to be withdrawn and an alternate provider path to be selected faster without unnecessary BGP timer churn.
