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. Please send comments to ospf@discuss.microsoft.com. Copyright Notice Copyright (C) The Internet Society (1999).

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 May 2001 [Page 3] Internet Draft OSPFv2 MIB November, 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 May 2001 [Page 4] Internet Draft OSPFv2 MIB November, 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 May 2001 [Page 5] Internet Draft OSPFv2 MIB November, 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 Expires May 2001 [Page 6] Internet Draft OSPFv2 MIB November, 2000 2.1.1 General Variables 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.
