The roadwarrior <b>carol</b> sets up an IPsec tunnel connection to the gateway
<b>moon</b>. Both end points activate <b>Dead Peer Detection</b> (DPD) with a
polling interval of 10 s. When the network connectivity between <b>carol</b>

clears the connection after 2 unsuccessful retransmits whereas <b>carol</b>
also takes down the connection but installs a route which triggers when
<b>carol</b> sends a ping to client <b>alice</b> behind gateway <b>moon</b>.
