Specify the interval between L2TP client and server.
To check the connectivity of a tunnel, the client and server
regularly send PPP Echo to each other. If the client or server
receives no response from the peer within a specified period of
time, it retransmits the PPP echo. If it receives no response from the
peer after transmitting the PPP echo for max retries times, it
considers that the L2TP tunnel is down and tries tore-establish a
tunnel with the peer.
