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> and <b>moon</b> is forcefully disrupted for a duration of 100 s, <b>moon</b> clears the connection after 4 unsuccessful retransmits whereas <b>carol</b> also takes down the connection but immediately tries to reconnect which succeeds as soon as the connection becomes available again.
