Cisco Maintaining Cisco Service Provider Routing Protocols (MSPRP） Sample Questions:
Which three statements correctly describe the BGP route-flap-dampening feature?
(Choose three)
- A. The penalty reduction rate is determined by the reuse limit.
- B. Each BGP route flap is penalized by adding 1000 penalty points to the penalty
- C. If a cumulative penalty exceeds the suppress limit, the route is dampened.
- D. When a penalty drops below the reuse limit or when the route has been dampened for more than the maximum suppress time, the route becomes valid again.
- E. The penalty is gradually decreased after the route stops flapping. When the penalty reaches one half of the reuse limit, the route is removed from the BGP table.
Refer to the exhibit.
Which ISIS feature needs to be configured to solve the incorrect load balancing of data traffic?
- A. Set the link between R1 and the L1/L2 router to a level 1-only link by using the isis circuit-type interface command
- B. Set the desired path to a higher priority by using the ip route priority high router level command.
- C. Tag the desired route by using the 'isis' tag interface command on R1 Gigabit Ethernet interface.
- D. Adjust the interface metrics to reflect the link bandwidths by using the 'isis metric interface command
To improve BGP performance in your network, you would like to withdraw routes immediately when the next hop of the route becomes unavailable instead of waiting for the scan interval to detect the problem. Which Cisco IOS software command will configure this failure?
