VRRP: (requires hardware version 2.0)

VRRP (Virtual Router Redundancy Protocol) allows you to associate

multiple routers with one LAN so that if the primary physical router fails, the

LAN will keep the same settings via the virtual router.

Enable VRRP: Select to enable VRRP configuration options.

Virtual Router IP: IP address of the virtual router. This must be distinct from

the IP address of any physical router associated with the virtual router.

Virtual Router ID: Identifying number of the virtual router. (Range: 1-255)

Router Priority: Failover priority level of this physical router. The physical

router with the highest priority number will have primary ownership of the

virtual router. (Range: 1-254)

WAN Fault Priority: This optional value sets the failover priority of this

router when no WAN connection is available. If the value matches the

normal router priority, WAN connection state will not be considered. If the

value is empty (the default), the router will always give up ownership of the

virtual IP and let a new master take over when no WAN connection is

available.

Advertisement Interval: Sets the amount of time (in seconds) between VRRP advertisements, which communicate the

router status. The default of 1 second is standard.

Initial Virtual Router State: This controls the initial VRRP failover state for this physical router: choose Master or

Backup. This sets up the virtual router association more quickly than the Router Priority level, but the Router Priority

assignment will eventually overrule this if there is a discrepancy.

Authentication: VRRP Authentication Method. This is for legacy purposes: VRRP Authentication has been deprecated

as of RFC 3768. Select None or Simple. If you select Simple, input a VRRP group password.

Provide Virtual IP in DHCP leases: Select this to automatically set the DHCP default gateway address and DNS server

address to the virtual IP in DHCP leases provided on this network.
