Preempt Mode
Use the drop-down menu to determine the behavior of backup routers within the
VRRP group by controlling whether a higher priority backup router will preempt a lower
priority Master router. If True is selected, and the backup router’s priority is higher than
the Master’s priority, the backup router will become the Master router. If False is
selected, the backup router with higher priority will not become the Master router. This
setting must be consistent with all routers participating within the same VRRP group.
Critical IP Address
Enter an IP address of the physical device that provides the most direct route to the
Internet or other critical network connections from this virtual router. This must be a
real IP address of a real device on the network. If the connection from the virtual router
to this IP address fails, the virtual router will automatically disabled. A new Master will
be chosen from the backup routers in the same VRRP group. Different critical IP
addresses may be assigned to different routers in the same VRRP group, and can
therefore define multiple routes to the Internet or other critical network connections.
