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
Internet Draft Expires November 2005 [Page 2]
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
Internet Draft Expires November 2005 [Page 4]
OSPFv3 MIB May 2005
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.
Internet Draft Expires November 2005 [Page 60]
OSPFv3 MIB May 2005
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.
(4) General Group object name ospfExternLsaCount is changed
Internet Draft Expires November 2005 [Page 61]
OSPFv3 MIB May 2005
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.
Internet Draft Expires November 2005 [Page 62]
OSPFv3 MIB May 2005
(20) Object ospfv3IfIndex added to Interface Table entry with
SYNTAX InterfaceIndex. It replaces ospfIfIpAddress and
ospfAddressLessIf as the Interface Table entry index.
(21) The SYNTAX of objects ospfIfDesignatedRouter and
ospfIfBackupDesignatedRouter is changed from IpAddress to
RouterID.
(22) Objects ospfIfAuthType and ospfIfAuthKey are removed from
Interface and Virtual Interface entries.
(23) 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.
(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.
(26) Added object ospfv3VirtIfIndex to Virtual Interface entry
which is used to assign a local interface ID to the
virtual interface.
(27) 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.
(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
components ospfNbrIpAddr and ospfNbrAddressLessIndex are

object contains the neighbor's IPv6 address.
(33) Removed objects ospfCfgNbrStatus and
Internet Draft Expires November 2005 [Page 63]
OSPFv3 MIB May 2005
ospfCfgNbrPermanence from Neighbor entry.
(34) Added object ospfv3NbrIfId to Neighbor entry. This object
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
ospfv3CfgNbrTable is ospfv3CfgNbrIfIndex,
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
ospfv3AreaAggregatePrefixLenth and SYNTAX from IpAddress
to InetAddressPrefixLength.
(42) Changed object name ospfAreaAggregateNet to
ospfv3AreaAggregatePrefix and SYNTAX from IpAddress to
InetAddress.
(43) Added object ospfv3AreaAggregatePrefixType to Area
Aggregate entry to determine the address type of
ospfv3AreaAggregatePrefix.
(44) Index for Area Aggregate Table entry changed from
ospfAreaAggregateAreaID, ospfAreaAggregateLsdbType,
ospfAreaAggregateNet, ospfAreaAggregateMask to
ospfv3AreaAggregateAreaID,
ospfv3AreaAggregateAreaLsdbType,
ospfv3AreaAggregatePrefixType, ospfv3AreaAggregatePrefix,
ospfv3AreaAggregatePrefixLength.
