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 the Open Shortest Path
First Routing Protocol.
This memo is intended to update and possibly obsolete 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 SNMPv2 Network Management Framework
This document describes aspects of the SNMPv2 Network Management
Framework, which consists of a number of components. They are:
- An overall architecture, described in RFC 2571 [1].
- 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].
- 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].
- 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].
- A set of fundamental applications described in RFC 2573
[14] and the view-based access control mechanism
described in RFC 2575 [15].
Expires March 2001 [Page 3]
Internet Draft OSPFv2 MIB September, 2000
1.2 The SMI, and Object Definitions
Managed objects are accessed via a virtual information store, termed
the Management Information Base or MIB. Objects in the MIB are
defined using the subset of Abstract Syntax Notation One (ASN.1)
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.
1.3 Object Identification
Objects in the SMI are defined by types, and are named by an
OBJECT IDENTIFIER, which is an administratively assigned name.
The object type together with an object instance serves to
uniquely identify a specific instantiation of the object. For
human convenience, we often use a textual string, termed
the descriptor, to refer to the object type.
1.4 Textual Conventions
Several data types in this MIB document are termed textual
conventions. Textual conventions enhance the readability
of the specification and can ease comparison with other
specifications if appropriate. It should be noted that
textual conventions have no effect on either the syntax nor
the semantics of any managed objects. Objects defined in
terms of one of these methods are always encoded by means
of the rules that define the primitive type. Textual
conventions are used for the convenience of readers and
writers in pursuit of the goal of clear, concise, and
unambiguous MIB documents.
1.5 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 which an agent should use for instances
of variables which need to be created due to a Set-Request, but which
are not specified in the Set-Request. DEFVAL clauses have not been
specified for some objects which 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 RFC-791):
"be liberal in what you accept, conservative in what you send"
Expires March 2001 [Page 4]
Internet Draft OSPFv2 MIB September, 2000
Therefor, 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.).
1.6 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. 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 that:
- 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.
Expires March 2001 [Page 5]
Internet Draft OSPFv2 MIB September, 2000
- The AreaID of each interface will be 0.0.0.0, the
Backbone.
- Authentication will be disabled
- All Broadcast and Point to Point interfaces will be
operational. 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.
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
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
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
Expires March 2001 [Page 6]
Internet Draft OSPFv2 MIB September, 2000
The General Variables describe (as it may seem from the name)
variables which 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 NSSA
translation.
The Area Stub Metric Table describes the metrics advertised into
a stub area by the default router(s).
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 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) 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.

-- OSPF Interface Metric Table
-- The Metric Table describes the metrics to be advertised
-- for a specified interface at the various types of service.
-- 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:
-- Metric = 10^8 / ifSpeed

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
Expires March 2001 [Page 73]
Internet Draft OSPFv2 MIB September, 2000
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 which use OSPF as its
IGP. It is an optional but very useful extension to the OSPF MIB.
4.2 Approach
The mechanism for sending traps is straight-forward. 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, ospfTxRetranmit 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 [24]. 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 traps types
except for the ospfLsdbOverflow and the ospfLsdbApproachingOverflow
Expires March 2001 [Page 74]
Internet Draft OSPFv2 MIB September, 2000
trap 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.
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 defined in section x.

-ospfLocalLsdbGroup, which specifies support for link local (type-
9) LSAs.
-ospfVirtLocalLsdbGroup, which specifies support for link local
(type-9) LSAs on virtual links.
B.7 OSPF Authentication and Security
As there has been significant concern in the community regarding
cascading security vulnerabilities, the following changes have been
incorporated:
-Modified the DESCRIPTION clause of ospfIfAuthKey due to
security concerns, and to increase clarity
-Modified the DESCRIPTION clause of ospfVirtIfAuthKey due to
security concerns, and to increase clarity
-Modified the DESCRIPTION clause of ospfIfAuthType due to
security concerns, and to increase clarity
-Modified the DESCRIPTION clause of ospfVirtIfType due to
security concerns, and to increase clarity
-Modified the OSPF MIB MODULE DESCRIPTION due to security
concerns and to include a reference to the security
considerations section in this document that will transcend
compilation
-Modified the security considerations section to provide
detail
B.8 Miscellaneous
Various sections, have been moved and or modified for clarity.
Most of these changes are semantic in nature, and include,
but are not limited to:
-The OSPF Overview section's format was revised. Unneeded
information was removed. Removed information includes OSPF TOS
default values.
-The Trap Overview section's format and working were revised.
Unneeded information was removed.
-Modified the DESCRIPTION clause of "Status" "TEXTUAL-CONVENTION"
for clarity
-The updates section was moved from the Overview to an appendix
-Updated "REFERENCE" clauses in all objects, as needed

Internet Draft OSPFv2 MIB September, 2000
-Modified the SEQUENCE of the OspfIfTable to reflect the true
order of the objects in the Table
Changed the "MAX-ACCESS" clause of
"ospfHostStatus" in "ospfHostTable" to "read-create"
C 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 2574 [RFC2574] and the View-
based Access Control Model RFC 2575 [RFC2575] 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.
