1. The Internet-Standard Management Framework

   For a detailed overview of the documents that describe the current
   Internet-Standard Management Framework, please refer to section 7 of
   RFC 3410 [RFC3410].

   Managed objects are accessed via a virtual information store, termed
   the Management Information Base or MIB. MIB objects are generally
   accessed through the Simple Network Management Protocol (SNMP).
   Objects in the MIB are defined using the mechanisms defined in the
   Structure of Management Information (SMI). This memo specifies a MIB
   module that is compliant to the SMIv2, which is described in STD 58,
   RFC 2578 [RFC2578], STD 58, RFC 2579 [RFC2579] and STD 58, RFC 2580
   [RFC2580]

2. Overview

   This memo defines a portion of the Management Information Base (MIB)
   for managing the Open Shortest Path First Routing Protocol for IPv6
   [RFC2740], otherwise known as OSPF version 3 (OSPFv3). Though the
   fundamental mechanisms of OSPF version 2 (OSPFv2) [RFC2328] remain
   unchanged in OSPFv3, some changes were necessary due to differences
   in IP address size and in protocol semantics between IPv4 and IPv6.
   In many cases, where the protocol operations have not changed from
   OSPFv2, the specification for OSPFv3 does not restate the details,
   but instead refers to the relevant sections in the OSPFv2
   specification. This MIB follows along the same lines and includes
   Reference clauses referring to the OSPFv2 specification when
   applicable.

   An attempt was made to align the OSPFv3 MIB as closely as possible
   with the OSPFv2 MIB. The following subsections highlight the major
   differences between the OSPFv2 MIB [RFC1850] and the OSPFv3 MIB. A
   detailed list of differences can be found in Appendix A.

   2.1. IPv6 Interfaces

   IPv6 interfaces attach to links [RFC2460]. A link is roughly defined
   as the layer below IPv6 (e.g. Ethernet, IPv4 Tunnel). One or more
   IPv6 prefixes can be associated with an IPv6 interface. IPv6
   interfaces and the prefixes associated with those interfaces can be
   configured via the IPV6-MIB [RFC2465]. IP-MIB [RFC4293]. IPv6 interfaces are configured
   in the IPv6 Interface Table and IPv6 prefixes are configured in the
   IPv6
   Internet Address Prefix Table. An IPv6 interface is identified by a
   unique index value. IPv6 Address Prefix Table entries associated with
   an IPv6 interface reference the interface's index.

   Whereas an interface identifier in OSPFv2 is a local IPv4 address or
   MIB-2 interface index, an OSPFv3 interface identifier is an IPv6
   interface index. For example, the index value of an OSPFv3 Interface
   Table entry is the IPv6 interface index of the IPv6 interface over
   which OSPFv3 is configured to operate.

   2.2. Addressing Semantics

   Router ID, Area ID and Link State ID remain at the OSPFv2 size of 32
   bits. To ensure uniqueness, a router running both IPv4 and IPv6
   concurrently can continue to use a local IPv4 host address,
   represented as an unsigned 32-bit value, as the OSPFv3 Router ID.
   Otherwise, the Router ID must be selected using another method (e.g.
   administratively assigned).

   Router ID, Area ID and Link State ID do not have addressing semantics
   in OSPFv3, so their syntax is changed to Unsigned32. The order of the Router ID and
   index component comes before the Link State ID index components in Link State Database
   Tables are reversed component in the
   OSPFv3 since MIB because the lack of addressing semantics in Link State IDs
   make them less unique identifiers than the Router ID. It is more
   useful to do partial OID lookups extending to the Router ID rather
   than the Link State ID.

   2.3. Authentication

   In OSPFv3, authentication has been removed from the protocol itself.
   MIB objects related to authentication are not carried forward from
   the OSPFv2 MIB.

   2.4. Type of Service

   OSPFv2 MIB objects related to Type of Service (ToS) are not carried
   forward to the OSPFv3 MIB.

   2.5. Flooding Scope

   Flooding scope for LSAs has been generalized and is now explicitly
   encoded in the LSA's LS type field. The action to take upon receipt
   of unknown LSA types is also encoded in the LS type field [RFC2740].
   The OSPFv3 MIB defines three Link State Database tables, one each
   for Area-scope LSAs, Link-scope LSAs and AS-scope LSAs.

   2.6. Virtual Links

   Since addressing semantics have been removed from router-LSAs in
   OSPFv3, Virtual Links now need to be assigned an interface ID for
   advertisement in Hello packets and in router-LSAs. A read-only
   object has been added to the Virtual Interface Table entry to view
   the assigned interface ID.

   2.7. Neighbors

   The OSPFv2 Neighbor Table has been split into two tables. The OSPFv3 Neighbor Table is a read-only table and it that contains
   information learned from Hellos received from neighbors, including Configured
   configured neighbors. The OSPFv3 Configured Neighbor Table contains
   entries for manually configured neighbors for use on NBMA and neighbors dynamically discovered by
   lower-level protocols such as Inverse Neighbor Discovery.

   2.8 Conventions

   The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL
   NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and
   "OPTIONAL"
   Point-to-Multipoint interface types.

   2.8. OSPFv3 Counters

   This MIB defines several counters, namely:

      - ospfv3OriginateNewLsas, ospfv3RxNewLsas in this document are to be interpreted as described the
        ospfv3GeneralGroup
      - ospfv3AreaSpfRuns, ospfv3AreaNssaTranslatorEvents in
   RFC 2119 [RFC2119].

3. Structure the
        ospfv3AreaTable
      - ospfv3IfEvents in the ospfv3IfTable
      - ospfv3VirtIfEvents in the ospfv3VirtIfTable
      - ospfv3NbrEvents in the ospfv3NbrTable
      - ospfv3VirtNbrEvents in the ospfv3VirtNbrTable

   As a best practice, a management entity, when reading these counters,
   should use the discontinuity object, ospfv3DiscontinuityTime, to
   determine if an event that would invalidate the management entity
   understanding of the counters has occurred. A restart of the OSPFv3 MIB

   The MIB
   routing process is composed a possible example of a discontinuity event.

   2.9. Multiple OSPFv3 Instances

   SNMPv3 supports "Contexts" that can be used to implement MIB views on
   multiple OSPFv3 instances on the following sections:

        General Variables
        Area Table
        Area-Scope Link State Database
        Link-Scope Link State Database
        AS-Scope Link State Database
        Host Table
        Interface Table
        Virtual Interface Table
        Neighbor Table
        Configured Neighbor Table
        Virtual Neighbor Table
        Aggregate Range Table

   3.1. General Variables same system.  See [RFC3411] or its
   successors for details.

   2.10. Conventions

   The General Variables key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL
   NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and
   "OPTIONAL" in this document are global to be interpreted as described in
   RFC 2119 [RFC2119].

3. OSPFv3 Notification Overview

   3.1. Introduction

      OSPFv3 is an event-driven routing protocol, where an event can be
      a change in an OSPFv3 interface's link-level status, the
      expiration of an OSPFv3 Process.

   3.2. Area Table

   The Area Data Structure describes timer, or the reception of an OSPFv3 Areas
      protocol packet. Many of the actions that OSPFv3 takes as a result
      of these events will result in a change of the
   router participates in.

   3.3. Area-Scope, Link-Scope routing topology.

      As routing topologies become large and AS-Scope Link State Database

   The Link State Databases are provided primarily to provide
   detailed information for network debugging.

   3.4. Host Table

   The Host Table complex, it is provided often
      difficult to view configured Host Route
   information.

   3.5. Interface Table

   The Interface Table describes locate the various IPv6 links source of a topology change or
      unpredicted routing path by polling a large number or routers.
      Because of the difficulty of polling a large number of devices,
      a more prudent approach is for devices to notify a network manager
      of potentially critical OSPF events using SNMP notifications.

   3.2 Ignoring Initial Activity
      The majority of critical events occur when OSPFv3 is enabled on a
      router, at which
   OSPFv3 time the designated router is configured.

   3.6. Virtual Interface Table elected and
      neighbor adjacencies are formed. During this initial period, a
      potential flood of notifications is unnecessary since the
      events are expected. To avoid unnecessary notifications, a
      router should not originate expected OSPFv3 interface-related
      notifications until two of that interface's dead timer intervals
      have elapsed. The Virtual Interface Table describes virtual expected OSPFv3 links.

   3.7. Neighbor, Configured Neighbor interface notifications are
      ospfv3IfStateChange, ospfv3VirtIfStateChange,
      ospfv3NbrStateChange, and Virtual Neighbor Tables ospfv3VirtNbrStateChange.

   3.3 Throttling Notifications

      The Neighbor Table, the Configured Neighbor Table and the Virtual
   Neighbor Table describe mechanism for throttling the neighbors notifications is similar to
      the OSPFv3 Process.

   3.8. Aggregate Range Table

   The Aggregate Range Table describes prefixes, which summarize
   routing information for export outside of an Area.

5. Security Considerations

   There are a number of management objects defined in this MIB
            "An ospfv3VirtIfConfigError notification signifies that
   have a MAX-ACCESS clause of read-write and/or read-create. Such
   objects may be considered sensitive or vulnerable in some network
   environments.  The support for SET operations in
            packet has been received on a non-secure
   environment without proper protection can have virtual interface
            from a negative effect on
   network operations.

   It is recommended that attention be specifically given to
   implementing the MAX-ACCESS clause in objects in scenarios router whose configuration parameters
            conflict with this router's configuration
            parameters. Note that DO NOT use SNMPv3 strong security (i.e. authentication and
   encryption). Extreme caution must be used to minimize the risk of
   cascading security vulnerabilities when SNMPv3 strong security is
   not used. When SNMPv3 strong security is not used, these objects event optionMismatch
            should have access of read-only, not read-create.

   SNMPv1 by itself is not cause a secure environment. Even notification only if it prevents an

6. Security Considerations

   There are a local interface ID to the
          virtual interface.

     (27) Added objects ospfv3VirtIfLinkScopeLsaCount and
          ospfv3VirtIfLinkLsaCksumSum to Virtual Interface entry.
          They maintain the count number of Link-Scope LSAs and the
          checksum management objects defined in this MIB that
   have a MAX-ACCESS clause of the Link-Scope LSA database associated with
          the virtual interface.

     (28) read-write and/or read-create. Such
   objects may be considered sensitive or vulnerable in some network
   environments.  The Neighbor Table (ospfv3NbrTable) is support for SET operations in a read-only table
          and it contains only the neighbors non-secure
   environment without proper protection can have a negative effect on
   network operations.

   It is recommended that were learned from
          LSAs.

     (29) Removed objects ospfNbrIpAddr and ospfNbrAddressLessIndex
          from Neighbor entry.

     (30) Added object ospfv3NbrIfIndex to Neighbor entry. Index
          components ospfNbrIpAddr and ospfNbrAddressLessIndex are
          replaced with ospfv3NbrIfIndex and ospfv3NbrRtrId.

     (31) Added object ospfv3NbrAddressType to Neighbor entry to
          determine the address type of ospfv3NbrAddress.

     (32) Added object ospfv3NbrAddress attention be specifically given to Neighbor entry. This
          object contains
   implementing the neighbor's IPv6 address.

     (33) Removed MAX-ACCESS clause in objects ospfCfgNbrStatus in scenarios
   that DO NOT use SNMPv3 strong security (i.e. authentication and
          ospfCfgNbrPermanence from Neighbor entry.

     (34) Added object ospfv3NbrIfId
   encryption). Extreme caution must be used to Neighbor entry. This object
          contains the neighbor's local interface index from the
          neighbor's hellos advertised on minimize the link.

     (35) The MAX-ACCESS value of object ospfNbrPriority is
          changed to read-only. Removed DEFVAL for object
          ospfv3NbrPriority.

     (36) Added ospfv3CfgNbrTable (Configured Neighbor Table)
          containing all manually configured neighbors. The index risk of
          ospfv3CfgNbrTable
   cascading security vulnerabilities when SNMPv3 strong security is ospfv3CfgNbrIfIndex,
          ospfv3CfgAddressType, and ospfv3CfgNbrAddress.

     (37) Added object ospfv3VirtNbrIfIndex to Virtual Neighbor
          entry.  This
   not used. When SNMPv3 strong security is the interface index not used, these objects
   should have access of read-only, not read-create.

   SNMPv1 by itself is not a secure environment. Even if the virtual link
          over which the virtual neighbor network
   itself is reached.

     (38) Changed object name ospfVirtNbrIpAddr to
          ospfv3VirtNbrAddress and SYNTAX from IpAddress to
          InetAddress.

     (39) Added object ospfv3VirtNbrAddressType to Virtual Neighbor
          entry secure (for example by using IPsec), even then, there is
   no control as to determine who on the address type of
          ospfv3VirtNbrAddress.

     (40) Added object ospfv3VirtNbrIfId secure network is allowed to Virtual Neighbor entry.
          This access and
   GET/SET (read/change/create/delete) the objects in this MIB.

   It is recommended that the virtual neighbor's local virtual interface
          index from implementers consider the neighbor's hellos advertised on security
   features as provided by the
          virtual link.

     (41) Changed object name ospfAreaAggregateMask to
          ospfv3AreaAggregatePrefixLenth SNMPv3 framework. Specifically, the use
   of the User-based Security Model RFC 3414 [RFC3414] and SYNTAX from IpAddress
          to InetAddressPrefixLength.

     (42) Changed object name ospfAreaAggregateNet the
   View-based Access Control Model RFC 3415 [RFC3415] is recommended.

   It is then a customer/user responsibility to
          ospfv3AreaAggregatePrefix and SYNTAX from IpAddress ensure that the SNMP
   entity giving access to
          InetAddress.

     (43) Added object ospfv3AreaAggregatePrefixType an instance of this MIB, is properly
   configured to Area
          Aggregate entry give access to determine the address type of
          ospfv3AreaAggregatePrefix.

     (44) Index for Area Aggregate Table entry changed from
          ospfAreaAggregateAreaID, ospfAreaAggregateLsdbType,
          ospfAreaAggregateNet, ospfAreaAggregateMask objects only to
          ospfv3AreaAggregateAreaID,
          ospfv3AreaAggregateAreaLsdbType,
          ospfv3AreaAggregatePrefixType, ospfv3AreaAggregatePrefix,
          ospfv3AreaAggregatePrefixLength.

     (45) Conformance information is changed those principals
   (users) that have legitimate rights to reflect object
          groups removed indeed GET or added.

     (46) OSPFv3 traps are not defined.

     (47) Added UNITS clause for the following objects:
          ospfv3ExitOverflowInterval,
          ospfv3AreaNssaTranslatorStabilityInterval,
          ospfv3AsLsdbAge, ospfv3AreaLsdbAge, ospfv3LinkLsdbAge,
          ospfv3IfTransitDelay, ospfv3IfRetransInterval,
          ospfv3IfHelloInterval, ospfv3IfRtrDeadInterval,
          ospfv3IfPollInterval, ospfv3VirtIfTransitDelay,
          ospfv3VirtIfRetransInterval, ospfv3VirtIfHelloInterval,
          ospfv3VirtIfRtrDeadInterval.

     (48) Changed SYNTAX from PositiveInteger to Unsigned32 for SET
   (change/create/delete) them.

7. IANA Considerations

   The MIB module in this document uses the following objects: ospfv3ExitOverflowInterval,
          ospfv3IfRtrDeadInterval, ospfv3IfPollInterval,
          ospfv3VirtIfRtrDeadInterval.

     (49) Changed MAX-ACCESS of row indices from read-only to
          not-accessible.

     (50) Added a new object ospfv3ExtLsaCount for support of RFC1765.

     (51) Compiled cleanly the MIB using "smilint -m -s -l 9 -i
           namelength-32".

     (52) Removed LSA type enumerations from IANA-assigned
   OBJECT IDENTIFIER values recorded in the LSDB tables, but
           ranges added as required by compiler.

     (53) Added object to LSDB tables SMI Numbers registry:

        Descriptor        OBJECT IDENTIFIER value
        ----------        -----------------------

        ospfv3MIB           { mib-2 XXX }

   [Editor's Note (to be removed prior to check if publication):  the LSA IANA is locally
           originated.

     (54) Add External Route Tag
   requested to AreaAggregate Table for NSSA.

     (55) Added Object assign a value for OSPFv3 Reference bandwidth.

     (56) Graceful restart objects to general group.

     (57) Graceful restart Objects "XXX" under the 'mib-2' subtree and
   to NBR MIBS.

     (58) ospfv3AreaSummary default value record the assignment in the SMI Numbers registry.  When the
   assignment has been changed made, the RFC Editor is asked to import
           summary LSA's replace "XXX"
   (here and in line the MIB module) with RFC3101.

     (59) Added support for inactive neighbor probing support over DC.

     (60) Removed ospfv3HostAddressType and ospfv3CfgNbrAddressType
           from the compliance module assigned value and to get compiler over warnings.
           The information remove
   this note.]
