Virtual Router field: Enables/Disables the virtual router.
Options: on/off
Default: on

Cluster field: Defines the cluster number for the virtual router. A cluster is a group of VRRP routers that are configured to emulate a virtual router.
Range: 0-255

Priority field: Indicates the preference of this router relative to the other routers forming the virtual router. Higher values equal higher priority. In the event that two or more routers within a cluster have equal priority, and that priority is the highest in the cluster, initially the router with the higher real interface IP address becomes the master router. Note: any new router joining the cluster with the same priority does not become master, even if it has a higher IP address, unless the current master goes down.
Range: 1-255
Default: 100

Hello Interval field: Specifies the time interval, in seconds, that the Master router sends advertisements that it is still running. The value in this field must be the same on all routers forming the virtual router.
Range: 1-255
Default: 1 second

Authentication field: Specifies the authentication method to use. None specifies no authentication; Simple specifies simple text password authentication. All routers forming the virtual router must be configured with the same authentication type. When you select Simple authentication and click the Apply button, the Password field displays.
Options: None, Simple
Default: None

Password field: Defines the authentication string. This field displays only after Simple authentication is selected. For Simple authentication, any VRRP packet with an authentication string not matching the locally-configured authentication string is discarded.
Range: One to eight alphanumeric characters (no spaces).
