Using the VRRP WAN watchdog
By default, VRRP WAN watchdog is disabled. When it is disabled, VRRP monitors the status of the master and slave
by the physical link. When enabled, the VRRP WAN watchdog feature monitors the status of the connection by
both the physical link and controlled ping packets. Refer to the Ping monitor section for more information on how
to configure the watchdog.
