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:
  1. ospfv3OriginateNewLsas and ospfv3RxNewLsas in the

ospfv3GeneralGroup

  1. ospfv3AreaSpfRuns and ospfv3AreaNssaTranslatorEvents in the

ospfv3AreaTable

  1. ospfv3IfEvents in the ospfv3IfTable
  1. ospfv3VirtIfEvents in the ospfv3VirtIfTable
  1. ospfv3NbrEvents in the ospfv3NbrTable
  1. 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).

Joyal & Manral Standards Track [Page 5] RFC 5643 OSPFv3 MIB August 2009

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.

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:
      Descriptor        OBJECT IDENTIFIER value
      ----------        -----------------------
      ospfv3MIB           { mib-2 191 }
