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.
STP
NOTE: STP requires a feature license. Go to
System Settings
→
Feature Licenses
to enable this feature.
