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.

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].
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).
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.
- 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.
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.
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.
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].
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.
The general variables describe (as it may seem from the name) variables that are global to the OSPF Process.
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).
The link state database is provided primarily to provide detailed information for network debugging.
The Address Range Table and Host Table are provided to view configured Network Summary and host route information.
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.
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.
The Neighbor Table and the Virtual Neighbor Table describe the neighbors to the OSPF Process.
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.
The AS-scope Link State Database Table is identical to the OSPF LSDB
Table in format, but contains only AS-scoped link state
advertisements.
The table, which maintains number of link state advertisements on the per-area, per-LSA-type basis.

MAX-ACCESS not-accessible

DESCRIPTION
"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 = 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."

-- ipCidrRouteMetric1 is, by definition, the primary routing
-- metric. Therefore, it should be the metric that route
-- selection is based on. For intra-area and inter-area routes,
-- it is an OSPF metric. For External Type 1 (comparable value)
-- routes, it is an OSPF metric plus the External Metric. For
-- external Type 2 (non-comparable value) routes, it is the
-- external metric. -- ipCidrRouteMetric2 is, by definition, a secondary routing
-- metric. Therefore, it should be the metric that breaks a tie
-- among routes having equal metric1 values and the same
-- calculation rule. For intra-area, inter-area routes, and
-- External Type 1 (comparable value) routes, it is unused. For
-- External Type 2 (non-comparable value) routes, it is the metric

DESCRIPTION
"The Area Aggregate Table acts as an adjunct
to the Area Table. It describes those address aggregates
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),
the most specific match is the preferred one."
