RFC 5643 OSPFv3 MIB August 2009
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
[RFC5340], 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 module follows along the same lines and includes Reference
clauses referring to the OSPFv2 specification when applicable.
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 IP-MIB [RFC4293]. IPv6 interfaces are configured
in the IPv6 Interface Table and IPv6 prefixes are configured in the
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.
Joyal & Manral Standards Track [Page 3]
RFC 5643 OSPFv3 MIB August 2009
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
Router ID index component comes before the Link State ID index
component in the OSPFv3 MIB module because the lack of addressing
semantics in Link State IDs makes them less unique identifiers than
the Router ID. It is more useful to do partial Object Identifier
(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 module.
2.4. Type of Service
OSPFv2 MIB module objects related to Type of Service (ToS) are not
carried forward to the OSPFv3 MIB module.
2.5. Flooding Scope
Flooding scope for link state advertisements (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 [RFC5340]. The OSPFv3 MIB module defines three
Link State Database tables, one each for Area-scope LSAs, Link-scope
LSAs, and Autonomous System (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.
Joyal & Manral Standards Track [Page 4]
RFC 5643 OSPFv3 MIB August 2009
2.7. Neighbors
The OSPFv3 Neighbor Table is a read-only table that contains
information learned from Hellos received from neighbors, including
configured neighbors. The OSPFv3 Configured Neighbor Table contains
entries for manually configured neighbors for use on non-broadcast
multi-access (NBMA) and Point-to-Multipoint interface types.
2.8. OSPFv3 Counters
This MIB module defines several counters, namely:
- ospfv3OriginateNewLsas and ospfv3RxNewLsas in the
ospfv3GeneralGroup
- ospfv3AreaSpfRuns and ospfv3AreaNssaTranslatorEvents in 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
routing process is an 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 same system. See [RFC3411] or its
successors for details.
2.10. Notifications
Notifications define a set of notifications, objects, and mechanisms
to enhance the ability to manage IP internetworks that use OSPFv3 as
their Interior Gateway Protocol (IGP).

2.11. Conventions
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
"SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
document are 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 timer, or the reception of an OSPFv3 protocol packet. Many
of the actions that OSPFv3 takes as a result of these events will
result in a change of the routing topology.
As routing topologies become large and complex, it is often difficult
to locate the 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.
The ospfv3NotificationEnable object provides a coarse level of
control over the generation of OSPFv3 notifications. It can be used
to completely enable or disable generation of OSPFv3 notifications.
Fine-grain control of individual notifications can be accomplished by
utilizing the objects defined in RFC 3413 [RFC3413], specifically
those described in Section 6.
3.2. Ignoring Initial Activity
The majority of critical events occur when OSPFv3 is enabled on a
router, at which time the Designated Router is 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 expected OSPFv3
interface notifications are ospfv3IfStateChange,
ospfv3VirtIfStateChange, ospfv3NbrStateChange, and
ospfv3VirtNbrStateChange.
3.3. Throttling Notifications
The mechanism for throttling the notifications is similar to the
mechanism explained in RFC 1224 [RFC1224]. The basic premise of the
throttling mechanism is that of a sliding window, defined in seconds
Joyal & Manral Standards Track [Page 6]
RFC 5643 OSPFv3 MIB August 2009
and with an upper bound on the number of notifications that may be
generated within this window. Note that unlike RFC 1224,
notifications are not sent to inform the network manager that the
throttling mechanism has kicked in.
A single window should be used to throttle all OSPFv3 notifications
types except for the ospfv3LsdbOverflow and the
ospfv3LsdbApproachingOverflow notifications, which should not be
throttled. For example, with a window time of 3, an upper bound of
3, and events to cause notifications 1, 2, 3, and 4 (4 notifications
within a 3-second period), the 4th notification should not be
generated.
Appropriate values are 7 notifications with a window time of 10
seconds.
3.4. One Notification per OSPFv3 Event
Several of the notifications defined in this MIB module are generated
as the result of finding an unusual condition while parsing an OSPFv3
packet or processing a timer event. There may be more than one
unusual condition detected while handling the event. For example, a
Link State Update packet may contain several retransmitted link state
advertisements (LSAs), or a retransmitted database description packet
may contain several database description entries. To limit the
number of notifications and variables, OSPFv3 should generate at most
one notification per OSPFv3 event. Only the variables associated
with the first unusual condition should be included with the
notification. Similarly, if more than one type of unusual condition
is encountered while parsing the packet, only the first event will
generate a notification.
3.5. Polling Event Counters
Many of the tables in the OSPFv3 MIB module contain generalized event
counters. By enabling the notifications defined in this document, a
network manager can obtain more specific information about these
events. A network manager may want to poll these event counters and
enable OSPFv3 notifications when a particular counter starts
increasing abnormally.
4. Structure of the OSPFv3 MIB Module
The MIB is composed of the following sections:
General Variables
Area Table
Area-Scope Link State Database
Joyal & Manral Standards Track [Page 7]
RFC 5643 OSPFv3 MIB August 2009
Link-Scope Link State Databases (non-virtual and virtual)
AS-Scope Link State Database
Host Table
Interface Table
Virtual Interface Table
Neighbor Table
Configured Neighbor Table
Virtual Neighbor Table
Area Aggregate Table
Notifications
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. There are separate tables for
Link-scope LSAs received over non-virtual and virtual interfaces.
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, 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.
4.8. Area Aggregate Table
The Area Aggregate Table describes prefixes, which summarize routing
information for export outside of an Area.
Joyal & Manral Standards Track [Page 8]
RFC 5643 OSPFv3 MIB August 2009
4.9. Notifications
Notifications are defined for OSPFv3 events. Several objects are
defined specifically as variables to be used with notifications.

Neighbors on multi-access or Point-to-Point
networks can use multicast addressing, so only
Neighbor table entries are created for them."

6. Security Considerations
There are a number of management objects defined in this MIB module
with 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. Improper manipulation of the objects represented
by this MIB module may result in disruption of network connectivity
by administratively disabling the entire OSPFv3 entity or individual
interfaces, by deleting configured neighbors, by reducing the limit
on External LSAs, by changing ASBR status, by manipulating route
aggregation, by manipulating interface and route metrics, by changing
Hello interval or dead interval, or by changing interface type.
Remote monitoring can be defeated by disabling of SNMP notifications.
Performance can be impacted by increasing the limit on External LSAs
or changing DR/BDR (Designated Router / Backup Designated Router)
priority.
Some of the readable objects in this MIB module (i.e., objects with a
MAX-ACCESS other than not-accessible) may be considered sensitive or
vulnerable in some network environments. It is thus important to
control even GET and/or NOTIFY access to these objects and possibly
to even encrypt the values of these objects when sending them over
the network via SNMP. Unauthorized access to readable objects in
this MIB module allows the discovery of the network topology and
operating parameters, which can be used to target further attacks on
the network or to gain a competitive business advantage.
Joyal & Manral Standards Track [Page 92]
RFC 5643 OSPFv3 MIB August 2009
SNMP versions prior to SNMPv3 did not include adequate security.
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 module.
It is RECOMMENDED that implementers consider the security features as
provided by the SNMPv3 framework (see [RFC3410], section 8),
including full support for the SNMPv3 cryptographic mechanisms (for
authentication and privacy).
Further, deployment of SNMP versions prior to SNMPv3 is NOT
RECOMMENDED. Instead, it is RECOMMENDED to deploy SNMPv3 and to
enable cryptographic security. It is then a customer/operator
responsibility to ensure that the SNMP entity giving access to an
instance of this MIB module 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.
7. IANA Considerations
The MIB module in this document uses the following IANA-assigned
OBJECT IDENTIFIER values recorded in the SMI Numbers registry:
