    Keepalived VRRP health check functionality to enable verification of
    connectivity from the "master" router to all gateways.
features:
  - Activation of this feature enables gateway connectivity validation and
    rescheduling of the "master" router to another node when connectivity
    is lost. If all routers lose connectivity to the gateways, the election
    process will be repeated round-robin until one of the routers restores
    its gateway connection. In the mean time, all of the routers will be
    reported as "master".
