1. Abstract

   This memo defines a portion of the Management Information Base (MIB)
   for use with network management protocols in IPv6-based internets. In
   particular, it defines objects for managing the Open Shortest Path
   First Routing Protocol for IPv6.

   This document specifies a MIB module in a manner that is both
   compliant to the SNMPv2 SMI, and semantically identical to the
   peer SNMPv1 definitions.

2. The SNMP Management Framework



Internet Draft          Expires September 2001                       1

                              OSPFv3 MIB                 February 2001


   The SNMP Management Framework presently consists of five major
   components:

   o    An overall architecture, described in RFC 2571 [1].

   o    Mechanisms for describing and naming objects and events
        for the purpose of management. The first version of this
        Structure of Management Information (SMI) is called SMIv1
        and described in STD 16, RFC 1155 [2], STD 16, RFC 1212
        [3] and RFC 1215 [4]. The second version, called SMIv2,
        is described in STD 58, RFC 2578 [5], RFC 2579 [6] and
        RFC 2580 [7].

   o    Message protocols for transferring management
        information. The first version of the SNMP message
        protocol is called SNMPv1 and described in STD 15, RFC
        1157 [8]. A second version of the SNMP message protocol,
        which is not an Internet standards track protocol, is
        called SNMPv2c and described in RFC 1901 [9] and RFC 1906
        [10]. The third version of the message protocol is called
        SNMPv3 and described in RFC 1906 [10], RFC 2572 [11] and
        RFC 2574 [12].

   o    Protocol operations for accessing management information.
        The first set of protocol operations and associated PDU
        formats is described in STD 15, RFC 1157  [8].  A second
        set of protocol operations and associated PDU formats is
        described in RFC 1905 [13].

   o    A set of fundamental applications described in RFC 2573
        [14] and the view-based access control mechanism
        described in RFC 2575 [15].

   A more detailed introduction to the current SNMP Management
   Framework can be found in RFC 2570 [16].

   Managed objects are accessed via a virtual information store,
   termed the Management Information Base or MIB. Objects in the
   MIB are defined using the mechanisms defined in the SMI.

   This memo specifies a MIB module that is compliant to the
   SMIv2. A MIB conforming to the SMIv1 can be produced through
   the appropriate translations. The resulting translated MIB
   must be semantically equivalent, except where objects or
   events are omitted because no translation is possible (use of
   Counter64). Some machine readable information in SMIv2 will be
   converted into textual descriptions in SMIv1 during the
   translation process. However, this loss of machine readable
   information is not considered to change the semantics of the
   MIB.

3. Overview

   This memo defines a portion of the Management Information Base (MIB)
   for managing the Open Shortest Path First Routing Protocol for IPv6,
   otherwise known as OSPF version 3 (OSPFv3). Though the fundamental
   mechanisms of OSPF version 2 (OSPFv2) remain unchanged in OSPFv3,
   some changes were necessary due to differences in IP address size and
   in protocol semantics between IPv4 and IPv6. 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 and the OSPFv3 MIB. A detailed list of differences can be
   found in Appendix A.

   3.1. IPv6 Interfaces

   IPv6 interfaces attach to links [17]. 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 [20]. 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.

   3.2. Addressing Semantics

   Router ID, Area ID and Link State ID remain at the OSPFv2 size of 32
   bits, therefore, they cannot be assigned IPv6 addresses. A router
   running both IPv4 and IPv6 concurrently can continue to use a local
   IPv4 interface address as the OSPFv3 router ID. Otherwise, the router
   ID must be selected using another method (e.g. administratively
   assigned). The Link State ID has no addressing semantics in OSPFv3.

   The syntax of Router ID, Area ID and Link State ID remains the same
   as in the OSPFv2 MIB(i.e. ipAddress). 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 LSID.

   3.3. Authentication

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

                              OSPFv3 MIB                 February 2001



   3.4. Type of Service

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

   3.5. Flooding Scope

   Flooding scope for LSAs has been generalized and is now explicitly
   coded in the LSA's LS type field. The action to take upon receipt of
   unknown LSA types is also coded in the LS type field [19]. The
   OSPFv3 MIB defines three Link State Database tables, one each for
   Area-scope LSAs, Link-scope LSAs and AS-scope LSAs.

   3.6. 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 row entry for this
   purpose.



4. 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
        Virtual Neighbor Table
        Aggregate Range Table

   4.1.  General Variables

   The General Variables are global to the OSPFv3 Process.

   4.2.  Area Table

   The Area Data Structure describes the OSPFv3  Areas  that  the
   router participates in.

   4.3.   Area-Scope, Link-Scope and AS-Scope Link State Database

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

   4.4.  Host Table

   The Host Table is  provided  to  view  configured  Host  Route
   information.

   4.5.  Interface Table

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

   4.6.  Virtual Interface Table

   The Virtual Interface Table describes virtual OSPFv3 links.

   4.7.  Neighbor and Virtual Neighbor Tables

   The Neighbor Table and the Virtual Neighbor Table describe the
   neighbors to the OSPFv3 Process.

   4.8.  Aggregate Range Table

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

8. 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 a 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.

A. Differences from RFC 1850

     (1)  Textual Conventions are imported from IPV6-TC  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.

     (4)  General Group object name ospfExternLsaCount  is  changed
          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  IPv6
          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 ospfv3HostIpv6Address with
          SYNTAX changed from IpAddress to Ipv6Address.

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

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

     (19) Object ospfv3IfIndex added to Interface Table entry  with
          SYNTAX  Ipv6IfIndex.   It  replaces  ospfIfIpAddress  and
          ospfAddressLessIf as the Interface Table entry index.

                              OSPFv3 MIB                 February 2001



     (20) The  SYNTAX   of   objects   ospfIfDesignatedRouter   and
          ospfIfBackupDesignatedRouter is changed from IpAddress to
          RouterID.

     (21) Objects ospfIfAuthType and ospfIfAuthKey are removed from
          Interface and Virtual Interface entries.

     (22) Added     objects      ospfv3IfLinkScopeLsaCount      and
          ospfv3IfLinkLsaCksumSum to Interface entry. They maintain
          the count of Link-Scope LSAs  and  the  checksum  of  the
          Link-Scope LSA database associated with the interface.

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

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

     (25) Added object ospfv3VirtIfIndex to Virtual Interface entry
          which  is  used  to  assign  a  local interface ID to the
          virtual interface.

     (26) Added    objects    ospfv3VirtIfLinkScopeLsaCount     and
          ospfv3VirtIfLinkLsaCksumSum  to  Virtual Interface entry.
          They maintain  the  count  of  Link-Scope  LSAs  and  the
          checksum  of  the Link-Scope LSA database associated with
          the virtual interface.

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

     (28) Added object ospfv3NbrIfIndex to Neighbor  entry.   Index
          components  ospfNbrIpAddr and ospfNbrAddressLessIndex are
          replaced with ospfv3NbrIfIndex and ospfv3NbrIpv6Addr.

     (29) Added object ospfv3NbrIfId to Neighbor entry. This object
          contains  the  neighbor's  local interface index from the
          neighbor's hellos advertised on the link.

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

     (31) Changed     object     name     ospfVirtNbrIpAddr      to
          ospfv3VirtNbrIpv6Addr   and   SYNTAX  from  IpAddress  to
          Ipv6Address.

     (32) 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.

     (33) Added object ospfv3AreaAggregateIndex to  Area  Aggregate
          entry.  This  allows  for  a  fixed length index for Area
          Aggregate Table entries.

     (34) Replaced      object      ospfAreaAggregateMask      with
          ospfv3AreaAggregatePrefixLen.

     (35) Replaced      object      ospfAreaAggregateNet       with
          ospfv3AreaAggregatePrefix.

     (36) Index  for  Area  Aggregate  Table  entry  changed   from
          ospfAreaAggregateAreaID,       ospfAreaAggregateLsdbType,
          ospfAreaAggregateNet,      ospfAreaAggregateMask       to
          ospfv3AreaAggregateAreaID,
          ospfv3AreaAggregateAreaLsdbType,
          ospfv3AreaAggregateIndex.

     (37) Conformance information  is  changed  to  reflect  object
          groups removed or added.

     (38) OSPFv3 traps are not defined.
