An ospfv3VirtIfStateChange notification signifies that there has been a change in the state of an OSPFv3 virtual interface. This notification should be generated when the interface state regresses (e.g., goes from Point-to-Point to Down) or progresses to a terminal state (i.e., Point-to-Point).

An ospfv3NbrStateChange notification signifies that there has been a change in the state of a non-virtual OSPFv3 neighbor. This notification should be generated when the neighbor state regresses (e.g., goes from Attempt or Full to 1-Way or Down) or progresses to a terminal state (e.g., 2-Way or Full). When a neighbor transitions from or to Full on non-broadcast multi-access and broadcast networks, the notification should be generated by the Designated Router. A Designated Router transitioning to Down will be noted by ospfIfStateChange.

This object is persistent, and when written, the entity SHOULD save the change to non-volatile storage.

The administrative status of OSPFv3 in the router. The value 'enabled' denotes that the OSPFv3 Process is active on at least one interface; 'disabled' disables it on all interfaces. This object is persistent, and when written, the entity SHOULD save the change to non-volatile storage.

This object permits management of the table by facilitating actions such as row creation, construction, and destruction. The value of this object has no effect on whether other objects in this conceptual row can be modified.

Prefixes subsumed by ranges will either trigger the advertisement of the indicated aggregate (advertiseMatching) or result in the prefix not being advertised at all outside the area. Enumeration: 'advertiseMatching': 1, 'doNotAdvertiseMatching': 2.

This tag is advertised only in the summarized As-External LSA when summarizing from NSSA-LSAs to AS-External-LSAs.

The OSPFv3 Process's Link-scope LSDB for virtual interfaces. The LSDB contains the Link-scope link state advertisements from virtual interfaces.

A single Link-scope link state advertisement for a virtual interface.

The transit area that the virtual link traverses. By definition, this is not Area 0.

The Router ID of the virtual neighbor.

The type of the link state advertisement. Each link state type has a separate advertisement format. Link-scope LSAs unrecognized by the router are also stored in this database.

The 32-bit number that uniquely identifies the originating router in the Autonomous System.

The Link State ID is an LS type-specific field containing a unique identifier; it identifies the piece of the routing domain that is being described by the advertisement. In contrast to OSPFv2, the LSID has no addressing semantics.

The sequence number field is a signed 32-bit integer. It is used to detect old and duplicate link state advertisements. The space of sequence numbers is linearly ordered. The larger the sequence number, the more recent the advertisement.

This field is the age of the link state advertisement in seconds. The high-order bit of the LS age field is considered the DoNotAge bit for support of on-demand circuits.

This field is the checksum of the complete contents of the advertisement, excepting the age field. The age field is excepted so that an advertisement's age can be incremented without updating the checksum. The checksum used is the same that is used for ISO connectionless datagrams; it is commonly referred to as the Fletcher checksum.

The entire link state advertisement, including its header.

The value true (1) indicates that the LSA type is recognized by this router.

Potential types of configuration conflicts. Used by the ospfv3ConfigError and ospfv3ConfigVirtError notifications. Enumeration: 'unknownNbmaNbr': 3, 'deadIntervalMismatch': 6, 'mtuMismatch': 8, 'badVersion': 1, 'noError': 10, 'unknownVirtualNbr': 4, 'optionMismatch': 7, 'helloIntervalMismatch': 5, 'areaMismatch': 2, 'duplicateRouterId': 9.

OSPFv3 packet types. Enumeration: 'lsAck': 5, 'lsReq': 3, 'nullPacket': 6, 'lsUpdate': 4, 'dbDescript': 2, 'hello': 1.

The IPv6 address of an inbound packet that cannot be identified by a neighbor instance. Only IPv6 addresses without zone index are expected.

The compliance statement

When this MIB module is implemented without support for read-create (i.e., in read-only mode), the implementation can claim read-only compliance. Such a device can then be monitored, but cannot be configured with this MIB.
