To save bandwidth resources, you can set an idle-cut timer.
An idle-cut timer specifies the period during which a tunnel continues to exist after the number of sessions in the tunnel reaches 0. When the timer expires, the tunnel is deleted.

An idle-cut timer is configured.
A tunnel with an idle-cut timer value 0 will never be actively deleted by the local end. However, the tunnel will not be set up again if the remote end deletes it.
The configuration is committed.
