CAfter the DPD function is enabled, the IPSec packet is not received within the interval specified by the interval, and the DPD sends a DPD request to the peer and waits for the response. Text

DDPD sends the query only before the encrypted message is sent and the timer expires.

Show Answer

Correct Answer: B

Note: IKE DPD needs to be enabled on both the master device and the tunnel peer device. After the switch is enabled, the peer device can quickly detect the tunnel and negotiate with the standby device. If the interval parameter is specified, the DPD works in the polling mode. If there is no traffic in the tunnel during the DPD detection interval, the DPD packet is sent periodically. Second, if the on-demand parameter is specified, it means that the DPD works in the traffic trigger mode. Since the last traffic end time, if there is no traffic in the tunnel during the DPD detection interval, the DPD report will be sent only when there is traffic. And the DPD detection time is recalculated from zero. Otherwise there will be no DPD messages in the tunnel. Third, if no interval or on-demand parameters are specified, DPD works in traffic trigger mode by default.
