</span>Sure, any IKEv2 exchange will do the trick of clearing out old sessions<br>
(e.g. rekeying too, however, the trigger is different, see below).<br>

</span>A DPD is sent only if there hasn't been any *inbound* traffic (IKE or<br>
ESP) for the last 10 hours. A first check for this occurs 10h after the<br>
SA got established, if there was traffic, the next check will be<br>
scheduled for 10h-time_since_last_packet etc.<br>
