Version 2 of the OSPF protocol 56 is specific to the IPv4 address family. Version 3 of the OSPF 57 protocol is specific to the IPv6 address family. 59 This memo is intended to update and obsolete RFC 1850, 60 however, it is designed to be backwards compatible. The functional 61 differences between this memo and RFC 1850 are explained in section 62 12. 64 Table of Contents 66 1.

Overview 118 1.1 The Internet-Standard Management Framework 120 For a detailed overview of the documents that describe the current 121 Internet-Standard Management Framework, please refer to section 7 of 122 RFC 3410 [RFC3410]. 124 Managed objects are accessed via a virtual information store, termed 125 the Management Information Base or MIB. MIB objects are generally 126 accessed through the Simple Network Management Protocol (SNMP). 127 Objects in the MIB are defined using the mechanisms defined in the 128 Structure of Management Information (SMI). This memo specifies a MIB 129 module that is compliant to the SMIv2, which is described in STD 58, 130 RFC 2578 [RFC2578], STD 58, RFC 2579 [RFC2579] and STD 58, RFC 2580 131 [RFC2580]. 133 1.2 Conceptual Row Creation 135 For the benefit of row-creation in "conceptual" tables, 136 DEFVAL (Default Value) clauses are included in the definitions in 137 section 3, suggesting values which an agent should use for instances 138 of variables which need to be created due to a Set-Request, but 139 which are not specified in the Set-Request. DEFVAL clauses have not 140 been specified for some objects which are read-only, implying that 141 they are zeroed upon row creation. These objects are of the SYNTAX 142 Counter32 or Gauge32. 144 For those objects not having a DEFVAL clause, both management 145 stations and agents should heed the Robustness Principle of the 146 Internet (see RFC-791): 148 "be liberal in what you accept, conservative in what you send" 150 Therefore, management stations should include as many of these 151 columnar objects as possible (e.g., all read-write objects) in a 152 Set-Request when creating a conceptual row. Agents should accept a 153 Set-Request with as few of these columnar objects as they need 154 (e.g., the minimum contents of a "row-creating" SET consists of 155 those objects for which, as they cannot be intuited, no default 156 is specified.). 158 1.3 Default Configuration 160 OSPF is a powerful routing protocol, equipped with features to 161 handle virtually any configuration requirement that might reasonably 162 be found within an Autonomous System. With this power comes a fair 163 degree of complexity, which the sheer number of objects in the MIB 164 will attest to. Care has therefore been taken, in constructing this 165 MIB, to define default values for virtually every object, to 166 minimize the amount of parameterization required in the typical 167 case. That default configuration is as follows: 169 Given the following assumptions: 171 - IP has already been configured 173 - The ifTable has already been configured 175 - ifSpeed is estimated by the interface drivers 177 - The OSPF Process automatically discovers all IP 178 Interfaces and creates corresponding OSPF Interfaces 180 - The OSPF Process automatically creates the Areas required 181 for the Interfaces 183 The simplest configuration of an OSPF process requires that: 185 - The OSPF Process be Enabled. 187 This can be accomplished with a single SET: 189 ospfAdminStat := enabled. 191 The configured system will have the following attributes: 193 - The RouterID will be one of the IP addresses of the 194 device 196 - The device will be neither an Area Border Router nor an 197 Autonomous System Border Router. 199 - Every IP Interface, with or without an address, will be 200 an OSPF Interface. 202 - The AreaID of each interface will be 0.0.0.0, the 203 Backbone. 205 - Authentication will be disabled 207 - All Broadcast and Point to Point interfaces will be 208 operational. NBMA Interfaces require the configuration 209 of at least one neighbor. 211 - Timers on all direct interfaces will be: 213 Hello Interval: 10 seconds 214 Dead Timeout: 40 Seconds 215 Retransmission: 5 Seconds 216 Transit Delay: 1 Second 217 Poll Interval: 120 Seconds 219 - No direct links to hosts will be configured. 221 - No addresses will be summarized 223 - Metrics, being a measure of bit duration, are unambiguous 224 and intelligent. 226 - No Virtual Links will be configured. 228 1.4 OSPF Counters 230 This MIB defines several counters, namely: 232 - ospfOriginateNewLsas, ospfRxNewLsas in the ospfGeneralGroup 233 - ospfSpfRuns, ospfAreaNssaTranslatorEvents in the ospfAreaTable 234 - ospfIfEvents in the ospfIfTable 235 - ospfVirtIfEvents in the ospfVirtIfTable 236 - ospfNbrEvents in the ospfNbrTable 237 - ospftVirtNbrEvents in the ospfVirtNbrEvents. 239 As a best practice, a management entity when reading these counters, 240 should use the discontinuity object ospfDiscontinuityTime, 241 to determine if an event, which would invalidate the management 242 entity understanding of the counters, has occurred. 243 A restart of the OSPF routing process is a possible example 244 of a discontinuity event. 246 1.5 Multiple OSPF Instances 248 SNMPv3 supports "Contexts" which can be used to implement MIB views 249 on multiple OSPF instances on the same system. See RFC 3411 250 or its successors for details. 252 2. Structure of this MIB 254 This MIB is composed of the following sections: 256 General Variables 257 Area Data Structure 258 Area Stub Metric Table 259 Link State Database 260 Address Range Table 261 Host Table 262 Interface Table 263 Interface Metric Table 264 Virtual Interface Table 265 Neighbor Table 266 Virtual Neighbor Table 267 External Link State Database 268 Aggregate Range Table 269 Local Link State Database 270 AS-scope Link State Database 272 There exists a separate MIB for notifications ("traps"), which is 273 entirely optional. 275 2.1 The Purposes of the sections in this MIB 277 2.1.1 General Variables 279 The General Variables describe (as it may seem from the name) 280 variables which are global to the OSPF Process. 282 2.1.2 Area Data Structure and Area Stub Metric Table 284 The Area Data Structure describes all of the OSPF Areas that the 285 router participates in. The Area Table includes data for NSSA 286 translation. 288 The Area Stub Metric Table describes the metrics advertised into 289 a stub area by the default router(s). 291 2.1.3 Link State Database and External Link State Database 293 The Link State Database is provided primarily to provide detailed 294 information for network debugging. 296 2.1.4 Address Table and Host Tables 298 The Address Range Table and Host Table are provided to view 299 configured Network Summary and Host Route information. 301 2.1.5 Interface and Interface Metric Tables 303 The Table and the Interface Metric Table together describe 304 the various IP interfaces to OSPF. The metrics are placed in 305 separate tables in order to simplify dealing with multiple types of 306 service. The Interface table includes Link-Local (Opaque Type-9) LSA 307 statistics. 309 2.1.6 Virtual Interface Table 311 The Virtual Interface Table describes virtual links to the 312 OSPF Process, similarly to the (non-Virtual)Interface Tables. This 313 table includes Link-Local (Opaque Type-9) LSA statistics. 315 2.1.7 Neighbor and Virtual Neighbor Tables 316 The Neighbor Table and the Virtual Neighbor Table describe the 317 neighbors to the OSPF Process. 319 2.1.8 Local Link State Database Table and Virtual 320 Local Link State Database Table 322 The Local Link State Database Table and Virtual Local Link State 323 Database Table are identical to the OSPF LSDB Table in 324 format, but contain only Link-Local (Opaque Type-9) Link State 325 Advertisements for non-virtual and virtual links. 327 2.1.9 AS-scope Link State Database Table 329 The AS-scope Link State Database Table is identical to the OSPF LSDB 330 Table in format, but contains only AS-scoped Link State 331 Advertisements. 333 2.1.10 Area Lsa Count Table 335 The table, which maintains number of link state advertisements 336 on the per area per LSA type basis. 338 3.

OSPF Trap Overview 4483 4.1 Introduction 4485 OSPF is an event driven routing protocol, where an event can be a 4486 change in an OSPF interface's link-level status, the expiration of 4487 an OSPF timer or the reception of an OSPF protocol packet. Many of 4488 the actions that OSPF takes as a result of these events will result 4489 in a change of the routing topology. 4491 As routing topologies become large and complex it is often difficult 4492 to locate the source of a topology change or unpredicted routing 4493 path by polling a large number or routers. Because of the difficulty 4494 of polling a large number of devices, a more prudent approach is for 4495 devices to notify a network manager of potentially critical OSPF 4496 events using SNMP traps. 4498 This section defines a set of traps, objects and mechanisms to 4499 enhance the ability to manage IP internetworks which use OSPF as its 4500 IGP. It is an optional but very useful extension to the OSPF MIB. 4502 4.2 Approach 4504 The mechanism for sending traps is straight-forward. When an 4505 exception event occurs, the application notifies the local agent who 4506 sends a trap to the appropriate SNMP management stations. The 4507 message includes the trap type and may include a list of trap 4508 specific variables. Section 5 gives the trap 4509 definitions which includes the variable lists. The router ID 4510 of the originator of the trap is included in the variable list 4511 so that the network manager may easily determine the source of the 4512 trap. 4514 To limit the frequency of OSPF traps, the following additional 4515 mechanisms are suggested. 4517 4.3 Ignoring Initial Activity 4519 The majority of critical events occur when OSPF is enabled on a 4520 router, at which time the designated router is elected and neighbor 4521 adjacencies are formed. During this initial period a potential 4522 flood of traps is unnecessary since the events are expected. To 4523 avoid unnecessary traps, a router should not originate expected OSPF 4524 interface related traps until two of that interface's dead timer 4525 intervals have elapsed. The expected OSPF interface traps are 4526 ospfIfStateChange, ospfVirtIfStateChange, ospfNbrStateChange, 4527 ospfVirtNbrStateChange, ospfTxRetranmit and ospfVirtIfTxRetransmit. 4528 Additionally, ospfMaxAgeLsa and ospfOriginateLsa traps should not be 4529 originated until two dead timer intervals have elapsed where the 4530 dead timer interval used should be the dead timer with the smallest 4531 value. 4533 4.4 Throttling Traps 4535 The mechanism for throttling the traps is similar to the mechanism 4536 explained in RFC 1224 [24]. The basic premise of the throttling 4537 mechanism is that of a sliding window, defined in seconds and an 4538 upper bound on the number of traps that may be generated within this 4539 window. Note that unlike RFC 1224, traps are not sent to inform the 4540 network manager that the throttling mechanism has kicked in. 4542 A single window should be used to throttle all OSPF traps types 4543 except for the ospfLsdbOverflow and the ospfLsdbApproachingOverflow 4544 trap which should not be throttled. For example, with a window time 4545 of 3, an upper bound of 3, and events to cause trap types 1,3,5 and 4546 7 (4 traps within a 3 second period), the type 7 (the 4th) trap 4547 should not be generated. 4549 Appropriate values are 7 traps with a window time of 10 seconds. 4551 4.5 One Trap Per OSPF Event 4553 Several of the traps defined in section 5 are 4554 generated as the result of finding an unusual condition while 4555 parsing an OSPF packet or a processing a timer event. There 4556 may be more than one unusual condition detected while handling 4557 the event. For example, a link-state update packet may contain 4558 several retransmitted link-state advertisements (LSAs), or a 4559 retransmitted database description packet may contain several 4560 database description entries. To limit the number of traps and 4561 variables, OSPF should generate at most one trap per OSPF event. 4562 Only the variables associated with the first unusual condition 4563 should be included with the trap. Similarly, if more than 4564 one type of unusual condition is encountered while parsing the 4565 packet, only the first event will generate a trap. 4567 4.6 Polling Event Counters 4569 Many of the tables in the OSPF MIB contain generalized event 4570 counters. By enabling the traps defined in this document a network 4571 manager can obtain more specific information about these events. A 4572 network manager may want to poll these event counters and enable 4573 specific OSPF traps when a particular counter starts increasing 4574 abnormally. 4576 The following table shows the relationship between the event 4577 counters defined in the OSPF MIB and the trap types. 4579 Counter32 Trap Type 4580 ----------------------- ------------------------ 4581 ospfOriginateNewLsas ospfOriginateLsa 4582 ospfIfEvents ospfIfStateChange 4583 ospfConfigError 4584 ospfIfAuthFailure 4585 ospfRxBadPacket 4586 ospfTxRetransmit 4587 ospfVirtIfEvents ospfVirtIfStateChange 4588 ospfVirtIfConfigError 4589 ospfVirtIfAuthFailure 4590 ospfVirtIfRxBadPacket 4591 ospfVirtIfTxRetransmit 4592 ospfNbrEvents ospfNbrStateChange 4593 ospfVirtNbrEvents ospfVirtNbrStateChange 4594 ospfExternLSACount ospfLsdbApproachingOverflow 4595 ospfExternLSACount ospfLsdbOverflow 4597 4.7 Translating Notification Parameters 4599 The definition of the OSPF notifications pre-dates the RFC 2578 4600 [RFC2578] requirement of having a zero value for the penultimate 4601 sub-identifier for translating SNMPv2/SNMPv3 trap parameters to 4602 SNMPv1 trap parameters. RFC 3584 [RFC3584], section 3 defines 4603 the translation rules which can be implemented by intermediate 4604 proxy-agents or multi-lingual agents to convert SNMPv2/SNMPv3 4605 notifications to SNMPv1 notifications and vice versa. 4606 The conversion is not reversible, that is, a conversion to one 4607 SNMP version and then back again will result in an incorrectly 4608 formatted version of the notification. 4610 According to the rules specified in RFC 3584, section 3.1, 4611 translation of OSPF notifications from SNMPv1 to SNMPv2/SNMPv3 4612 would result in the SNMPv2/SNMPv3 snmpTrapOID being the 4613 concatenation of the SNMPv1 'enterprise' parameter and two 4614 additional sub-identifiers, '0' and the SNMPv1 'specific-trap' 4615 parameter. 4617 According to the rules specified in RFC 3584, section 3.2, 4618 translation of OSPF notifications from SNMPv2/SNMPv3 to SNMPv1, 4619 as the notifications are defined in this MIB, would result in 4620 the SNMPv1 'enterprise' parameter being set to the 4621 SNMPv2/SNMPv3 snmpTrapOID parameter value with the last 4622 sub-identifier removed and the 'specific-trap' parameter being 4623 set to the last sub-indentifier of the SNMPv2/SNMPv3 snmpTrapOID 4624 parameter. 4626 5.

Security Considerations 5210 There are a number of management objects defined in this MIB that 5211 have a MAX-ACCESS clause of read-write and/or read-create. Such 5212 objects may be considered sensitive or vulnerable in some network 5213 environments. The support for SET operations in a non-secure 5214 environment without proper protection can have a negative effect on 5215 network operations. 5217 It is recommended that attention be specifically given to 5218 implementing the MAX-ACCESS clause in a number of objects, including 5219 ospfIfAuthKey, ospfIfAuthType, ospfVirtIfAuthKey, and 5220 ospfVirtIfAuthType in scenarios that DO NOT use SNMPv3 strong 5221 security (i.e. authentication and encryption). Extreme caution must 5222 be used to minimize the risk of cascading security vulnerabilities 5223 when SNMPv3 strong security is not used. When SNMPv3 strong security 5224 is not used, these objects should have access of read-only, not 5225 read-create. 5227 SNMPv1 by itself is not a secure environment. Even if the network 5228 itself is secure (for example by using IPsec), even then, there is 5229 no control as to who on the secure network is allowed to access and 5230 GET/SET (read/change/create/delete) the objects in this MIB. 5232 It is recommended that the implementers consider the security 5233 features as provided by the SNMPv3 framework. Specifically, the use 5234 of the User-based Security Model RFC 3414 [RFC3414] and the 5235 View-based Access Control Model RFC 3415 [RFC3415] is recommended. 5237 It is then a customer/user responsibility to ensure that the SNMP 5238 entity giving access to an instance of this MIB, is properly 5239 configured to give access to the objects only to those principals 5240 (users) that have legitimate rights to indeed GET or SET 5241 (change/create/delete) them. 5243 7.
