On a VRRP router, a given virtual router is identified by a combination of the IF index and VRID. Rows in the table cannot be modified unless the value of `vrrpOperAdminState' is `disabled' and the `vrrpOperState' has transitioned to `initialize'."

Although this object can be derived from the 'vrrpOperVrId' object, it is defined so that it is easily obtainable by a management application and can be included in VRRP-related SNMP traps." ::= { vrrpOperEntry 2 } vrrpOperState OBJECT-TYPE SYNTAX INTEGER { initialize(1), backup(2), master(3) } MAX-ACCESS read-only STATUS current DESCRIPTION "The current state of the virtual router. This object has three defined values: - `initialize', which indicates that all the virtual router is waiting for a startup event. - `backup', which indicates the virtual router is monitoring the availability of the master router. - `master', which indicates that the virtual router is forwarding packets for IP addresses that are associated with this router.

Setting the value to `up', will transition the state of the virtual router from `initialize' to `backup' or `master', depending on the value of `vrrpOperPriority'. Setting the value to `down', will transition the router from `master' or `backup' to `initialize'. State transitions may not be immediate; they sometimes depend on other factors, such as the interface (IF) state. The `vrrpOperAdminState' object must be set to `down' prior to modifying the other read-create objects in the conceptual row. The value of the `vrrpOperRowStatus' object (below) must be `active', signifying that the conceptual row is valid (i.e., the objects are correctly set), in order for this object to be set to `up'." DEFVAL { down } ::= { vrrpOperEntry 4 } vrrpOperPriority OBJECT-TYPE SYNTAX Integer32 (0..255) MAX-ACCESS read-create STATUS current DESCRIPTION "This object specifies the priority to be used for the virtual router master election process. Higher values imply higher priority. A priority of '0', although not settable, is sent by the master router to indicate that this router has ceased to participate in VRRP and a backup virtual router should transition to become a new master. A priority of 255 is used for the router that owns the associated IP address(es)."

This number is equal to the number of rows in the vrrpAssoIpAddrTable that correspond to a given IF index/VRID pair." ::= { vrrpOperEntry 6 } vrrpOperMasterIpAddr OBJECT-TYPE SYNTAX IpAddress MAX-ACCESS read-only STATUS current DESCRIPTION "The master router's real (primary) IP address.
