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.
