Enable PING to Keep Alive is used to handle
abnormal IPSec VPN connection disruption. It will help
to provide the state of a VPN connection for router's
judgment of redial.
Normally, if any one of VPN peers wants to disconnect
the connection, it should follow a serial of packet
exchange procedure to inform each other. However, if
the remote peer disconnect without notice, Vigor router
will by no where to know this situation. To resolve this
dilemma, by continuously sending PING packets to the
remote host, the Vigor router can know the true
existence of this VPN connection and react accordingly.
This is independent of DPD (dead peer detection).
