Method
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).
