OSPF Version 2 Management Information Base
Status of This Memo
This document specifies an Internet standards track protocol for the
Internet community, and requests discussion and suggestions for
improvements. Please refer to the current edition of the "Internet
Official Protocol Standards" (STD 1) for the standardization state
and status of this protocol. Distribution of this memo is unlimited.

Abstract
This memo defines a portion of the Management Information Base (MIB)
for use with network management protocols in TCP/IP-based internets.
In particular, it defines objects for managing version 2 of the Open
Shortest Path First Routing Protocol. Version 2 of the OSPF protocol
is specific to the IPv4 address family. Version 3 of the OSPF
protocol is specific to the IPv6 address family.
This memo obsoletes RFC 1850; however, it is designed to be backwards
compatible. The functional differences between this memo and RFC
1850 are explained in Appendix B.

1. Overview
1.1. 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].
1.2. Conceptual Row Creation
For the benefit of row-creation in "conceptual" tables, DEFVAL
(Default Value) clauses are included in the definitions in section 3,
suggesting values that an agent should use for instances of variables
that need to be created due to a Set-Request, but that are not
specified in the Set-Request. DEFVAL clauses have not been specified
for some objects that are read-only, implying that they are zeroed
upon row creation. These objects are of the SYNTAX Counter32 or
Gauge32.
For those objects not having a DEFVAL clause, both management
stations and agents should heed the Robustness Principle of the
Internet (see [RFC791]):
"be liberal in what you accept, conservative in what you send"
Therefore, management stations should include as many of these
columnar objects as possible (e.g., all read-write objects) in a
Set-Request when creating a conceptual row. Agents should accept a
Set-Request with as few of these columnar objects as they need (e.g.,
the minimum contents of a "row-creating" SET consists of those
objects for which, as they cannot be intuited, no default is
specified).
Galecki, et al. Standards Track [Page 3]RFC 4750 OSPFv2 MIB December 2006
1.3. Default Configuration
OSPF is a powerful routing protocol, equipped with features to handle
virtually any configuration requirement that might reasonably be
found within an Autonomous System (AS). With this power comes a fair
degree of complexity, which the sheer number of objects in the MIB
will attest to. Care has therefore been taken, in constructing this
MIB, to define default values for virtually every object, to minimize
the amount of parameterization required in the typical case. That
default configuration is as follows:
Given the following assumptions:
- IP has already been configured.
- The ifTable has already been configured.
- ifSpeed is estimated by the interface drivers.
- The OSPF process automatically discovers all IP interfaces and
creates corresponding OSPF interfaces.
- The OSPF process automatically creates the areas required for the
interfaces.
The simplest configuration of an OSPF process requires the following:
- The OSPF process be enabled.
This can be accomplished with a single SET:
ospfAdminStat := enabled.
The configured system will have the following attributes:
- The RouterID will be one of the IP addresses of the device.
- The device will be neither an Area Border Router nor an Autonomous
System Border Router.
- Every IP interface, with or without an address, will be an OSPF
interface.
- The AreaID of each interface will be 0.0.0.0, the backbone.
- Authentication will be disabled.
Galecki, et al. Standards Track [Page 4]RFC 4750 OSPFv2 MIB December 2006
- All broadcast and point-to-point interfaces will be operational.
Non-broadcast multi-access (NBMA) interfaces require the
configuration of at least one neighbor.
- Timers on all direct interfaces will be:
Hello Interval: 10 seconds
Dead Timeout: 40 Seconds
Retransmission: 5 Seconds
Transit Delay: 1 Second
Poll Interval: 120 Seconds
- No direct links to hosts will be configured.
- No addresses will be summarized.
- Metrics, being a measure of bit duration, are unambiguous and
intelligent.
- No virtual links will be configured.
1.4. OSPF Counters
This MIB defines several counters, namely:
- ospfOriginateNewLsas, ospfRxNewLsas in the ospfGeneralGroup
- ospfSpfRuns, ospfAreaNssaTranslatorEvents in the ospfAreaTable
- ospfIfEvents in the ospfIfTable
- ospfVirtIfEvents in the ospfVirtIfTable
- ospfNbrEvents in the ospfNbrTable
- ospfVirtNbrEvents in the ospfVirtNbrTable
As a best practice, a management entity, when reading these counters,
should use the discontinuity object, ospfDiscontinuityTime, to
determine if an event that would invalidate the management entity
understanding of the counters has occurred. A restart of the OSPF
routing process is a possible example of a discontinuity event.
1.5. Multiple OSPF Instances
SNMPv3 supports "Contexts" that can be used to implement MIB views on
multiple OSPF instances on the same system. See [RFC3411] or its
successors for details.
Galecki, et al. Standards Track [Page 5]RFC 4750 OSPFv2 MIB December 2006
1.6. 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].
2. Structure of This MIB
This MIB is composed of the following sections:
General Variables
Area Data Structure
Area Stub Metric Table
Link State Database (LSDB)
Address Range Table
Host Table
Interface Table
Interface Metric Table
Virtual Interface Table
Neighbor Table
Virtual Neighbor Table
External Link State Database
Aggregate Range Table
Local Link State Database
AS-scope Link State Database
It supports the base OSPFv2 specification [RFC2328] and extensions to
OSPFv2 such as [RFC1765], [RFC1793], [RFC2370], [RFC3101] and
[RFC3623].
There exists a separate MIB for notifications ("traps"), which is
entirely optional.
2.1. The Purposes of the Sections in This MIB
2.1.1. General Variables
The general variables describe (as it may seem from the name)
variables that are global to the OSPF Process.
2.1.2. Area Data Structure and Area Stub Metric Table
The Area Data Structure describes all of the OSPF Areas that the
router participates in. The Area Table includes data for Not-So-
Stubby-Area (NSSA) translation.
The Area Stub Metric Table describes the metrics advertised into a
stub area by the default router(s).
Galecki, et al. Standards Track [Page 6]RFC 4750 OSPFv2 MIB December 2006
2.1.3. Link State Database and External Link State Database
The link state database is provided primarily to provide detailed
information for network debugging.
2.1.4. Address Table and Host Tables
The Address Range Table and Host Table are provided to view
configured Network Summary and host route information.
2.1.5. Interface and Interface Metric Tables
The Interface Table and the Interface Metric Table together describe
the various IP interfaces to OSPF. The metrics are placed in
separate tables in order to simplify dealing with multiple types of
service. The Interface table includes link-local (Opaque type-9)
link state advertisement (LSA) statistics.
2.1.6. Virtual Interface Table
The Virtual Interface Table describes virtual links to the OSPF
Process, similarly to the (non-virtual) Interface Tables. This Table
includes link-local (Opaque type-9) LSA statistics.
2.1.7. Neighbor and Virtual Neighbor Tables
The Neighbor Table and the Virtual Neighbor Table describe the
neighbors to the OSPF Process.
2.1.8. Local Link State Database Table and Virtual Local Link State
Database Table
The Local Link State Database Table and Virtual Local Link State
Database Table are identical to the OSPF LSDB Table in format, but
contain only link-local (Opaque type-9) link state advertisements for
non-virtual and virtual links.
2.1.9. AS-scope Link State Database Table
The AS-scope Link State Database Table is identical to the OSPF LSDB
Table in format, but contains only AS-scoped link state
advertisements.
2.1.10. Area LSA Count Table
The table, which maintains number of link state advertisements on the
per-area, per-LSA-type basis.

DESCRIPTION
"The Metric Table describes the metrics to be advertised

As such, this table is an adjunct of the OSPF Interface
Table.
Types of service, as defined by RFC 791, have the ability
to request low delay, high bandwidth, or reliable linkage.
For the purposes of this specification, the measure of
bandwidth:
Galecki, et al. Standards Track [Page 45]RFC 4750 OSPFv2 MIB December 2006
Metric = referenceBandwidth / ifSpeed
is the default value.
The default reference bandwidth is 10^8.
For multiple link interfaces, note that ifSpeed is the sum
of the individual link speeds. This yields a number having
the following typical values:
Network Type/bit rate Metric
>= 100 MBPS 1
Ethernet/802.3 10
E1 48
T1 (ESF) 65
64 KBPS 1562
56 KBPS 1785
19.2 KBPS 5208
9.6 KBPS 10416
Routes that are not specified use the default
(TOS 0) metric.
Note that the default reference bandwidth can be configured
using the general group object ospfReferenceBandwidth."

DESCRIPTION
"The Area Aggregate Table acts as an adjunct

that are configured to be propagated from an area.
Its purpose is to reduce the amount of information
that is known beyond an Area's borders.
It contains a set of IP address ranges
specified by an IP address/IP network mask pair.
For example, a class B address range of X.X.X.X
with a network mask of 255.255.0.0 includes all IP
addresses from X.X.0.0 to X.X.255.255.
Note that if ranges are configured such that one range
subsumes another range (e.g., 10.0.0.0 mask 255.0.0.0
and 10.1.0.0 mask 255.255.0.0),

4. OSPF Trap Overview
4.1. Introduction
OSPF is an event-driven routing protocol, where an event can be a
change in an OSPF interface's link-level status, the expiration of an
OSPF timer, or the reception of an OSPF protocol packet. Many of the
actions that OSPF 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 traps.
This section defines a set of traps, objects, and mechanisms to
enhance the ability to manage IP internetworks that use OSPF as their
Interior Gateway Protocol (IGP). It is an optional but very useful
extension to the OSPF MIB.
Galecki, et al. Standards Track [Page 94]RFC 4750 OSPFv2 MIB December 2006
4.2. Approach
The mechanism for sending traps is straightforward. When an
exception event occurs, the application notifies the local agent, who
sends a trap to the appropriate SNMP management stations. The
message includes the trap type and may include a list of trap-
specific variables. Section 5 gives the trap definitions, which
includes the variable lists. The Router ID of the originator of the
trap is included in the variable list so that the network manager may
easily determine the source of the trap.
To limit the frequency of OSPF traps, the following additional
mechanisms are suggested.
4.3. Ignoring Initial Activity
The majority of critical events occur when OSPF 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 traps is unnecessary since the events are expected. To
avoid unnecessary traps, a router should not originate expected OSPF
interface-related traps until two of that interface's dead timer
intervals have elapsed. The expected OSPF interface traps are
ospfIfStateChange, ospfVirtIfStateChange, ospfNbrStateChange,
ospfVirtNbrStateChange, ospfTxRetransmit, and ospfVirtIfTxRetransmit.
Additionally, ospfMaxAgeLsa and ospfOriginateLsa traps should not be
originated until two dead timer intervals have elapsed where the dead
timer interval used should be the dead timer with the smallest value.
4.4. Throttling Traps
The mechanism for throttling the traps 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 and an
upper bound on the number of traps that may be generated within this
window. Note that unlike RFC 1224, traps are not sent to inform the
network manager that the throttling mechanism has kicked in.
A single window should be used to throttle all OSPF trap types except
for the ospfLsdbOverflow and the ospfLsdbApproachingOverflow traps,
which should not be throttled. For example, with a window time of 3,
an upper bound of 3, and events to cause trap types 1, 3, 5, and 7 (4
traps within a 3-second period), the type-7 (the 4th) trap should not
be generated.
Appropriate values are 7 traps with a window time of 10 seconds.
Galecki, et al. Standards Track [Page 95]
RFC 4750 OSPFv2 MIB December 2006
4.5. One Trap Per OSPF Event
Several of the traps defined in section 5 are generated as the result
of finding an unusual condition while parsing an OSPF packet or a
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 traps and variables, OSPF should generate at most one trap
per OSPF event. Only the variables associated with the first unusual
condition should be included with the trap. Similarly, if more than
one type of unusual condition is encountered while parsing the
packet, only the first event will generate a trap.
4.6. Polling Event Counters
Many of the tables in the OSPF MIB contain generalized event
counters. By enabling the traps 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
specific OSPF traps when a particular counter starts increasing
abnormally.
The following table shows the relationship between the event counters
defined in the OSPF MIB and the trap types.

Galecki, et al. Standards Track [Page 96]RFC 4750 OSPFv2 MIB December 2006
4.7. Translating Notification Parameters
The definition of the OSPF notifications pre-dates the RFC 2578
[RFC2578] requirement of having a zero value for the penultimate
sub-identifier for translating SNMPv2/SNMPv3 trap parameters to
SNMPv1 trap parameters. RFC 3584 [RFC3584], section 3, defines the
translation rules that can be implemented by intermediate proxy-
agents or multi-lingual agents to convert SNMPv2/SNMPv3 notifications
to SNMPv1 notifications and vice versa. The conversion is not
reversible, that is, a conversion to one SNMP version and then back
again will result in an incorrectly formatted version of the
notification.
According to the rules specified in RFC 3584, section 3.1,
translation of OSPF notifications from SNMPv1 to SNMPv2/SNMPv3 would
result in the SNMPv2/SNMPv3 snmpTrapOID being the concatenation of
the SNMPv1 'enterprise' parameter and two additional sub-identifiers,
'0' and the SNMPv1 'specific-trap' parameter.
According to the rules specified in RFC 3584, section 3.2,
translation of OSPF notifications from SNMPv2/SNMPv3 to SNMPv1, as
the notifications are defined in this MIB, would result in the SNMPv1
'enterprise' parameter being set to the SNMPv2/SNMPv3 snmpTrapOID
parameter value with the last sub-identifier removed and the
'specific-trap' parameter being set to the last sub-identifier of the
SNMPv2/SNMPv3 snmpTrapOID parameter.
Note that a notification originated from an SNMPv1 agent will not be
converted into the same notification that would be originated from a
native SNMPv2/SNMPv3 agent.
4.8. Historical Artifacts
The MIB modules that are updated by this document were originally
written in SMIv1 for SNMPv1 when only traps were used. Since this
version of the MIB module is written in SMIv2, it should be
understood that all types of notifications, trap and inform PDUs, may
be used by native SNMPv2 and SNMPv3 agents, although only traps are
mentioned. Also, for backwards compatibility, the OSPF Trap module
remains rooted at {ospf 16}.

6. 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.
It is recommended that attention be specifically given to
implementing the MAX-ACCESS clause in a number of objects, including
ospfIfAuthKey, ospfIfAuthType, ospfVirtIfAuthKey, and
ospfVirtIfAuthType in scenarios that DO NOT use SNMPv3 strong
security (i.e., authentication and encryption). Extreme caution must
be used to minimize the risk of cascading security vulnerabilities
when SNMPv3 strong security is not used. When SNMPv3 strong security
is not used, these objects should have access of read-only, not
read-create.
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 3414 [RFC3414] and the View-
based Access Control Model RFC 3415 [RFC3415] 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.
