Parameter
Note
: When negotiating to set up IPSec SAs, IKE uses the smaller one
between the lifetime set locally and the lifetime proposed by the peer.
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.
