DPD Time Interval
Set the interval after which DPD is triggered if no IPSec protected packets is
received from the peer.
DPD: Dead peer detection. DPD irregularly detects dead IKE peers. When the
local end sends an IPSec packet, DPD checks the time the last IPSec packet was
received from the peer. If the time exceeds the DPD interval, it sends a DPD
hello to the peer. If the local end receives no DPD acknowledgment within the
DPD packet retransmission interval, it retransmits the DPD hello. If the local
end still receives no DPD acknowledgment after having made the maximum
number of retransmission attempts, it considers the peer already dead, and
clears the IKE SA and the IPSec SAs based on the IKE SA.
