"An entry in the vrrpOperTable containing the operational
characteristics of a virtual router. 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

DESCRIPTION
"This object contains the Virtual Router Identifier (VRID)."
::= { vrrpOperEntry 1 }
vrrpOperVirtualMacAddr OBJECT-TYPE
SYNTAX MacAddress
MAX-ACCESS read-only
STATUS current
DESCRIPTION
"The virtual MAC address of the virtual router. 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 }

SYNTAX INTEGER {

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 `vrrpOperAdminState' object (below) initiates
transitions in the value of this object."
::= { vrrpOperEntry 3 }
vrrpOperAdminState OBJECT-TYPE
SYNTAX INTEGER {
up(1),
down(2)
}
MAX-ACCESS read-create
STATUS current
DESCRIPTION
"This object will enable/disable the virtual router
function. 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)."
DEFVAL { 100 }
::= { vrrpOperEntry 5 }
vrrpOperIpAddrCount OBJECT-TYPE
SYNTAX Integer32 (0..255)
MAX-ACCESS read-only
STATUS current
DESCRIPTION
"The number of IP addresses that are associated with this
virtual router. 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. This is
the IP address listed as the source in VRRP advertisement
last received by this virtual router."
::= { vrrpOperEntry 7 }
vrrpOperPrimaryIpAddr OBJECT-TYPE
SYNTAX IpAddress
MAX-ACCESS read-create
STATUS current
DESCRIPTION
"In the case where there is more than one IP address for
a given `ifIndex', this object is used to specify the IP
address that will become the `vrrpOperMasterIpAddr', should
the virtual router transition from backup to master. If
this object is set to 0.0.0.0, the IP address which is
numerically lowest will be selected."

-- the IP authentication header.
}
MAX-ACCESS read-create

DESCRIPTION
"Authentication type used for VRRP protocol exchanges between
virtual routers. This value of this object is the same for a
given ifIndex.
New enumerations to this list can only be added via a new
RFC on the standards track."
DEFVAL { noAuthentication }
::= { vrrpOperEntry 9 }
vrrpOperAuthKey OBJECT-TYPE
SYNTAX OCTET STRING (SIZE (0..16))
MAX-ACCESS read-create
STATUS current
DESCRIPTION
"The Authentication Key. This object is set according to
the value of the 'vrrpOperAuthType' object
('simpleTextPassword' or 'ipAuthenticationHeader'). If the
length of the value is less than 16 octets, the agent will
left adjust and zero fill to 16 octets. The value of this
object is the same for a given ifIndex.
When read, vrrpOperAuthKey always returns an Octet String
of length zero."
::= { vrrpOperEntry 10 }
vrrpOperAdvertisementInterval OBJECT-TYPE
SYNTAX Integer32 (1..255)

MAX-ACCESS read-create

VRRP advertisements."

vrrpOperVirtualRouterUpTime OBJECT-TYPE
SYNTAX TimeStamp
MAX-ACCESS read-only
STATUS current
DESCRIPTION
"This is the value of the `sysUpTime' object when this
virtual router (i.e., the `vrrpOperState') transitioned
out of `initialized'."

RFC on the standards track."
DEFVAL { ip }
::= { vrrpOperEntry 14 }
vrrpOperRowStatus OBJECT-TYPE
SYNTAX RowStatus
MAX-ACCESS read-create
STATUS current
DESCRIPTION
"The row status variable, used in accordance to installation
and removal conventions for conceptual rows. The rowstatus of
a currently active row in the vrrpOperTable is constrained
by the operational state of the corresponding virtual router.
When `vrrpOperRowStatus' is set to active(1), no other
objects in the conceptual row, with the exception of
`vrrpOperAdminState', can be modified. Prior to setting the
`vrrpOperRowStatus' object from `active' to a different value,
the `vrrpOperAdminState' object must be set to `down' and the
`vrrpOperState' object be transitioned to `initialize'.
To create a row in this table, a manager sets this object
to either createAndGo(4) or createAndWait(5). Until instances
of all corresponding columns are appropriately configured,
the value of the corresponding instance of the `vrrpOperRowStatus'
column will be read as notReady(3).
In particular, a newly created row cannot be made active(1)
until (minimally) the corresponding instance of
`vrrpOperVrId' has been set and there is at least one active
row in the `vrrpAssoIpAddrTable' defining an associated
IP address for the virtual router."

MAX-ACCESS not-accessible

DESCRIPTION
"An entry in the table contains an IP address that is
associated with a virtual router. The number of rows for
a given ifIndex and VrId will equal the number of IP
addresses associated (e.g., backed up) by the virtual
router (equivalent to 'vrrpOperIpAddrCount').
Rows in the table cannot be modified unless the value
of `vrrpOperAdminState' is `disabled' and the
`vrrpOperState' has transitioned to `initialize'."

DESCRIPTION
"The row status variable, used according to installation

object to active(1) or createAndGo(4) results in the
addition of an associated address for a virtual router.
Destroying the entry or setting it to notInService(2)
removes the associated address from the virtual router.
The use of other values is implementation-dependent."
