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

                              OSPFv3 MIB                      May 2005


   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]. IPv6 interfaces are configured
   in the IPv6 Interface Table and IPv6 prefixes are configured in the
   IPv6 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 Link State ID index components in Link State Database
   Tables are reversed in OSPFv3 since 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

Internet Draft          Expires November 2005                [Page 3]


                              OSPFv3 MIB                      May 2005



   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. An object has
   been added to the Virtual Interface Table entry for this purpose.

   2.7. Neighbors

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


3. Structure of the OSPFv3 MIB

   The MIB is composed of 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

   The General Variables are global to the OSPFv3 Process.

   3.2. Area Table

   The Area Data Structure describes the OSPFv3 Areas that the

   router participates in.

   3.3. Area-Scope, Link-Scope 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 is provided to view configured Host Route
   information.

   3.5. Interface Table

   The Interface Table describes the various IPv6 links on which
   OSPFv3 is configured.

   3.6. Virtual Interface Table

   The Virtual Interface Table describes virtual OSPFv3 links.

   3.7. Neighbor, Configured Neighbor and Virtual Neighbor Tables

   The Neighbor Table, the Configured Neighbor Table and the Virtual
   Neighbor Table describe the neighbors 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. IANA Considerations

   The MIB module in this document uses the following IANA-assigned
   OBJECT IDENTIFIER values recorded in the SMI Numbers registry:

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

        ospfv3MIB           { mib-2 XXX }

   [Editor's Note (to be removed prior to publication):  the IANA is
   requested to assign a value for "XXX" under the 'mib-2' subtree and
   to record the assignment in the SMI Numbers registry.  When the
   assignment has been made, the RFC Editor is asked to replace "XXX"
   (here and in the MIB module) with the assigned value and to remove
   this note.]

9. Security Considerations

   There are a number of management objects defined in this MIB
   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 a
   non-secure environment without proper protection can have a
   negative effect on network operations.

   SNMPv1 by itself is not a secure environment. Even if the network
   itself is secure (for example by using IPSec), even then, there is
   no control as to who on the secure network is allowed to access and
   GET/SET (read/change/create/delete) the objects in this MIB.

   It is recommended that the implementers consider the security
   features as provided by the SNMPv3 framework. Specifically, the use
   of the User-based Security Model RFC 2574 [12] and the View-based
   Access Control Model RFC 2575 [15] is recommended.

   It is then the customer/user responsibility to ensure that the SNMP
   entity giving access to an instance of this MIB, is properly
   configured to give access to the objects only to those principals
   (users) that have legitimate rights to indeed GET or SET
   (change/create/delete) them.

12. Differences from RFC 1850

     (1)  Textual Conventions are imported  from  INET-ADDRESS-MIB,
          IF-MIB and OSPF-MIB MIBs.

     (2)  The  "ospf"  prefix  for  entity  names  is  changed   to
          "ospfv3".

     (3)  General Group object name ospfVersionNumber is changed to
          ospfv3VersionNumber and its value is changed from 2 to 3.

          to  ospfv3AsScopeLsaCount  to  indicate  count of all AS-
          scoped LSAs in the database.

     (5)  General  Group  object  name   ospfExternLsaCksumSum   is
          changed  to ospfv3AsScopeCksumSum to indicate checksum of
          all AS-scoped LSAs in the database.

     (6)  Removed General Group object ospfTOSSupport.

     (7)  Removed ospfAuthType object from Area entry.

     (8)  Changed     object     names     ospfAreaLsaCount     and
          ospfAreaLsaCksumSum    to   ospfv3AreaScopeLsaCount   and
          ospfv3AreaScopeLsaCksumSum.

     (9)  Removed OSPF Area Default Metric Table.

     (10) Added object ospfv3StubMetric to Area entry as substitute
          for Area Default Metric Table.

     (11) Changed name of External  LSDB  Table  to  AS-Scope  LSDB
          Table.   Replaced  object  name prefix "ospfExtLsdb" with
          "ospfv3AsLsdb".

     (12) Changed name of LSDB  Table  to  Area-Scope  LSDB  Table.
          Replaced    object    name    prefix    "ospfLsdb"   with
          "ospfv3AreaLsdb".

     (13) Added ospfv3LinkLsdbTable  which  contains  all  LSAs  of
          Link-Scope. Index  of  ospfv3LinkLsdbTable  is  interface
          index, LSA Type, Router ID and LSID.

     (14) Re-ordered Router ID and LSID index  components  of  LSDB
          table  entries.   Since  LSIDs  no longer have addressing
          semantics, GET-NEXT operations on partial OIDs  are  more
          useful when the Router ID component comes before the LSID
          component.

     (15) Address Range Table is removed.

     (16) Removed  ospfHostTOS  from  Host  Table   entry.   Object
          ospfHostIpAddress  changed  to ospfv3HostAddress with
          SYNTAX changed from IpAddress to InetAddress.

     (17) Added object ospfv3HostAddressType to Host Table entry to
          determine the address type of ospfv3HostAddress.

     (18) The  MAX-ACCESS  value  of  object  ospfv3HostAreaID   is
          changed to read-create.

     (19) Objects  ospfIfIpAddress  and  ospfAddressLessIf  removed
          from  Interface  entry and as Interface Table entry index
          components.

          Link-Scope LSA database associated with the interface.

     (24) Removed  OSPF  Interface  Metric  Table.  Metric  is  now
          accessed  via object ospfv3IfMetricValue in the Interface
          entry.

     (25) Added object ospfv3IfInstId to Interface entry to  enable
          the  setting  of  the  interface  instance  value  of the
          interface. The default value is zero.

          which  is  used  to  assign  a  local interface ID to the
          virtual interface.

     (27) Added    objects    ospfv3VirtIfLinkScopeLsaCount     and
          ospfv3VirtIfLinkLsaCksumSum  to  Virtual Interface entry.

          checksum  of  the Link-Scope LSA database associated with
          the virtual interface.

     (28) The Neighbor Table (ospfv3NbrTable) is a read-only  table
          and it contains only the neighbors that were learned from
          LSAs.

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

     (30) Added object ospfv3NbrIfIndex to Neighbor  entry.   Index

          contains  the  neighbor's  local interface index from the
          neighbor's hellos advertised on 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) which
          contains all  manually  configured  neighbors.  Index  of

          ospfv3CfgAddressType,              ospfv3CfgNbrAddress.



     (37) Added object  ospfv3VirtNbrIfIndex  to  Virtual  Neighbor
          entry.  This  is  the interface index of the virtual link
          over which the virtual neighbor is reached.

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

     (39) Added object ospfv3VirtNbrAddressType to Virtual Neighbor
          entry     to    determine    the    address    type    of
          ospfv3VirtNbrAddress.

     (40) Added object ospfv3VirtNbrIfId to Virtual Neighbor entry.
          This  is  the  virtual neighbor's local virtual interface
          index  from  the  neighbor's  hellos  advertised  on  the
          virtual link.

     (41) Changed    object     name    ospfAreaAggregateMask    to
