NEW QUESTION # 566
As shown in the figure, there are the following configurations under BGP, which of the following descriptions are wrong? (Multiple choice)
[HUAWEI-bgp] timer keepalive 30 hold 90
[HUAWEI-bgp] peer 1.1.2 timer keepalive 10 hold 30
- A. Timer takes the minimum value, so the final result is that the timer value of peer 1.1.1.2 takes keepalive10 hold 30
- B. Peer configuration takes precedence, so the final result is that the timer value of peer 1.1.1.2 takes keepalive 10 hold 30
- C. Global configuration takes precedence, so the final result is that the timer value of peer 1.1.1.2 takes keepalive 30 hold 90
