IV. Configuring the idle timeout period for the sessions
A session is torn down if no packet passes through it during a specified interval known
as the idle timeout period.
Perform the following configuration in a DVPN policy view.

The default idle timeout period for the sessions is 300 seconds.
V. Configuring the interval for sending keepalive packets
After a session is established, the active side sends keepalive packets regularly to
check the connection status of the session if no data passes through the session. If the
active side receives no keepaliveack packet after sending three successive keepalive
packets, it assumes that the session is disconnected.
Perform the following configuration in DVPN policy view.
