Monitor interface function of VRRP better expands backup function: the backup function can be
offered when interface of a certain router has fault or other interfaces of the router are unavailable.
When uplink interface is Down or Removed, the router actively reduces its priority so that the
priority of other routers in the backup group is higher and thus the router with highest priority
becomes the gateway for the transmission task.
From navigation tree, select "Network >>VRRP" menu, then enter “VRRP” page.
