Introduction 80 This document describes a model for managing RBridges (Routing 81 Bridges), also known as TRILL Switches, as defined in [RFC6325]. 82 RBridges provide optimal pair-wise forwarding without configuration 83 using IS-IS routing and encapsulation of traffic. RBridges are 84 compatible with previous IEEE 802.1 customer bridges as well as IPv4 85 and IPv6 routers and end nodes. They are as invisible to current IP 86 routers as bridges are and, like routers, they terminate the bridge 87 spanning tree protocol. In creating an RBridge management model the 88 device is viewed primarily as a customer bridge. For a discussion of 89 the problem addressed by TRILL (Transparent Interconnection of Lots 90 of Links) see [RFC5556]. 92 RBridges support features specified for transparent bridges in IEEE 93 802.1, and the corresponding MIB modules are used to manage those 94 features. For IS-IS purposes, the corresponding MIB module is used to 95 manage the protocol. This MIB module specifies those objects which 96 are TRILL-specific and hence not available in other MIB modules. 98 2. The Internet-Standard Management Framework 100 For a detailed overview of the documents that describe the current 101 Internet-Standard Management Framework, please refer to section 7 of 102 RFC 3410 [RFC3410]. 104 Managed objects are accessed via a virtual information store, termed 105 the Management Information Base or MIB. MIB objects are generally 106 accessed through the Simple Network Management Protocol (SNMP). 107 Objects in the MIB are defined using the mechanisms defined in the 108 Structure of Management Information (SMI). This memo specifies a MIB 109 module that is compliant to the SMIv2, which is described in STD 58, 110 which consists of [RFC2578], [RFC2579] and [RFC2580]. 112 3. Overview 114 The RBridge MIB module is intended as an overall framework for 115 managing RBridges, also known as TRILL Switches. Where possible the 116 MIB references existing MIB definitions in order to maximize reuse. 117 This results in a considerable emphasis on the relationship with 118 other MIB modules. 120 Starting with the physical interfaces, there are requirements for 121 certain elements of the IF-MIB to be implemented. These elements are 122 required in order to connect the per-port parameters to higher level 123 functions of the physical device. 125 Transparent bridging, VLANs, Traffic classes and Multicast Filtering 126 are supported by the TRILL protocol, and the corresponding management 127 is expected to conform to the BRIDGE-MIB [RFC4188], P-BRIDGE-MIB and 128 Q-BRIDGE-MIB [RFC4363] modules. 130 The IS-IS routing protocol is used in order to determine the optimum 131 pair-wise forwarding path. This protocol is managed using the IS-IS 132 MIB module defined in [RFC4444]. Since the TRILL protocol specifies 133 use of a single level and a fixed area address of zero, some IS-IS 134 MIB objects are not applicable. Some IS-IS MIB objects are used in 135 the TRILL protocol. 137 4. Conventions 139 The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", 140 "SHOULD", "SHOULD NOT", "RECOMMENDED", "NOT RECOMMENDED", "MAY", and 141 "OPTIONAL" in this document are to be interpreted as described in RFC 142 2119 [RFC2119]. 144 5. Structure of the MIB Module 146 Objects in this MIB module are arranged into subtrees. Each subtree 147 is organized as a set of related objects. The various subtrees are 148 shown below. These are supplemented with required elements of the IF- 149 MIB, ISIS-MIB, BRIDGE-MIB, P-BRIDGE-MIB, Q-BRIDGE-MIB and IEEE Bridge 150 MIB modules. 152 5.1 Textual Conventions 154 Textual conventions are defined to represent object types relevant to 155 TRILL. 157 5.2 The rbridgeBase Subtree 159 This subtree contains system and port specific objects applicable to 160 all RBridges. 162 5.3 The rbridgeFdb Subtree 164 This subtree contains objects applicable to the Forwarding database 165 used by the RBridge in making packet forwarding decisions. Because it 166 contains additional information used by the TRILL protocol not 167 applicable to 802.1D/Q bridges, it is a superset of the corresponding 168 subtrees defined in the BRIDGE-MIB and Q-BRIDGE-MIB. 170 5.4 The rbridgeVlan subtree 172 This subtree describes objects applicable to VLANs configured on the 173 RBridge. 175 5.5 The rbridgeEsadi subtree 177 This subtree describes objects relevant to RBridges that support the 178 optional ESADI protocol. 180 5.6 The rbridgeCounters subtree 182 This subtree contains statistics maintained by RBridges that can aid 183 in monitoring and troubleshooting networks connected by them. 185 5.7 The rbridgeSnooping subtree 187 This subtree describes objects applicable to RBridges capable of 188 snooping IPv4 and/or IPv6 Multicast control frames and pruning IP 189 multicast traffic based on detection of IP multicast routers and 190 listeners. 192 5.8 The rbridgeDtree subtree 194 This subtree contains objects relevant to Distribution Trees computed 195 by RBridges for the forwarding of multi-destination frames. 197 5.9 The rbridgeTrill subtree 199 This subtree contains objects applicable to the TRILL IS-IS protocol, 200 beyond what is available in ISIS-MIB. 202 5.10 The Notifications Subtree 204 The defined notifications are focused on the TRILL protocol 205 functionality. Notifications are defined for changes in the 206 Designated RBridge status and the topology. 208 6. Relationship to Other MIB Modules 210 The IF-MIB, BRIDGE-MIB, P-BRIDGE-MIB, Q-BRIDGE-MIB, IEEE8021-BRIDGE- 211 MIB, IEEE8021-Q-BRIDGE-MIB and ISIS-MIB modules all contain objects 212 relevant to the RBridge MIB. Management objects contained in these 213 modules are not duplicated here, to reduce overlap to the extent 214 possible. 216 The Bridge MIB modules were originally written in the IETF, and 217 implemented by many vendors. Per [RFC4663], this has recently been 218 transferred to the IEEE 802.1 group. As vendors may have implemented 219 either the IETF or IEEE Bridge MIB modules, this RBridge MIB module 220 is designed to work with either one. 222 6.1 Relationship to IF-MIB 224 The port identification elements MUST be implemented in order to 225 allow them to be cross referenced. The Interface MIB [RFC2863] 226 requires that any MIB module which is an adjunct of the Interface MIB 227 clarify specific areas within the Interface MIB module. These areas 228 were intentionally left vague in the Interface MIB module to avoid 229 over-constraining the MIB, thereby precluding management of certain 230 media types. Section 4 of [RFC2863] enumerates several areas which a 231 media-specific MIB module must clarify. The implementor is referred 232 to [RFC2863] in order to understand the general intent of these 233 areas. 235 6.2 Relationship to BRIDGE-MIB 237 The following subtrees in the BRIDGE-MIB [RFC4188] contain 238 information relevant to RBridges when the corresponding functionality 239 is implemented. 241 o dot1dBase 242 o dot1dTp 243 o dot1dStatic 245 6.3 Relationship to P-BRIDGE-MIB 247 The following subtrees in the P-BRIDGE-MIB [RFC4363] contain 248 information relevant to RBridges when the corresponding functionality 249 is implemented. 251 o dot1dExtBase 252 o dot1dPriority 253 o dot1dGarp 254 o dot1dGmrp 255 o dot1dTpHCPortTable 256 o dot1dTpPortOverflowTable 258 6.4 Relationship to Q-BRIDGE-MIB 260 The following groups in the Q-BRIDGE-MIB [RFC4363] contain 261 information relevant to RBridges when the corresponding functionality 262 is implemented. This functionality is also contained in IEEE8021-Q- 263 BRIDGE-MIB. 265 o dot1qBase 266 o dot1qTp 267 o dot1qStatic 268 o dot1qVlan 269 o dot1vProtocol 271 6.5 Relationship to IEEE8021-BRIDGE-MIB 273 The following subtrees in the IEEE8021-BRIDGE-MIB contain information 274 relevant to RBridges when the corresponding functionality is 275 implemented. 277 o ieee8021BridgeBase 278 o ieee8021BridgeTp 279 o ieee8021BridgePriority 280 o ieee8021BridgeMrp 281 o ieee8021BridgeMmrp 282 o ieee8021BridgeInternalLan 283 o ieee8021BridgeDot1d 285 6.6 Relationship to IEEE8021-Q-BRIDGE-MIB 287 The following subtrees in the IEEE8021-Q-BRIDGE-MIB contain 288 information relevant to RBridges when the corresponding functionality 289 is implemented. 291 o ieee8021QBridgeBase 292 o ieee8021QBridgeTp 293 o ieee8021QBridgeStatic 294 o ieee8021QBridgeVlan 295 o ieee8021QBridgeProtocol 297 6.7 Relationship to ISIS-MIB 299 The Management Information Base for Intermediate System to 300 Intermediate System (IS-IS)[RFC4444] defines a MIB module for the IS- 301 IS Routing protocol when it is used to construct routing tables for 302 IP networks. While most of these objects are applicable to the TRILL 303 layer 2 implementation, note the IS-IS constraints for the current 304 version of TRILL [RFC6325]: 306 o The TRILL IS-IS instance uses a single Level 1 IS-IS area. 308 o The TRILL Level 1 IS-IS area uses the fixed area address zero. 310 o The TRILL IS-IS instance is not used for IP address advertisement. 312 o The TRILL IS-IS instance is used for only a single protocol: TRILL. 314 Accordingly, tables which report IP address reachability and tables 315 which allow configuration or reporting of multiple IS-IS areas, 316 multiple IS-IS levels or multiple protocols, will be empty in the 317 ISIS-MIB module for the current version of TRILL. 319 Note also that when more than one instance of the IS-IS protocol is 320 running on a device, as in the case of a device performing both 321 RBridge and IS-IS IP router functions, multiple instances of the 322 ISIS-MIB module can be distinguished by the use of SNMPv3 contexts or 323 SNMPv1 communities. 325 6.8 MIB modules required for IMPORTS 327 The following MIB module IMPORTS objects from SNMPv2-SMI [RFC2578], 328 SNMPv2-TC [RFC2579], SNMPv2-CONF [RFC2580], IF-MIB [RFC2863], 329 INET-ADDRESS-MIB[RFC4001], BRIDGE-MIB[RFC4188] and 330 Q-BRIDGE-MIB[RFC4363].

Security Considerations 2458 This MIB relates to a system which will provide network connectivity 2459 and packet forwarding services. As such, improper manipulation of the 2460 objects represented by this MIB may result in denial of service to a 2461 large number of end-users. 2463 There are a number of management objects defined in this MIB module 2464 with a MAX-ACCESS clause of read-write and/or read-create. Such 2465 objects may be considered sensitive or vulnerable in some network 2466 environments. The support for SET operations in a non-secure 2467 environment without proper protection can have a negative effect on 2468 network operations. These tables and objects and their 2469 sensitivity/vulnerability are described below. 2471 The following tables and objects in the RBRIDGE-MIB can be 2472 manipulated to interfere with the operation of RBridges: 2474 o rbridgeBaseUniMultipathEnable affects the ability of the RBridge to 2475 multipath unicast traffic, and rbridgeBaseMultiMultipathEnable 2476 affects the ability of the Rbridge to multipath multi-destination 2477 traffic. 2479 o rbridgeBasePortTable contains a number of objects that may affect 2480 network connectivity. Actions that may be triggered by manipulating 2481 objects in this table include disabling of an RBridge port; 2482 discarding of native packets; disabling learning and others. 2484 o rbridgeEsadiTable contains objects that affect the operation of the 2485 ESADI protocol used for learning, and manipulation of the objects 2486 contained therein can be used to confuse the learning ability of 2487 Rbridges. 2489 o rbridgeDtreePriority can affect computation of distribution trees 2490 within an Rbridge campus, thereby affecting forwarding of multi- 2491 destination traffic. 2493 o rbridgeTrillMinMtuDesired can affect the size of packets being used 2494 to exchange information between RBridges. 2496 Some of the readable objects in this MIB module (i.e., objects with a 2497 MAX-ACCESS other than not-accessible) may be considered sensitive or 2498 vulnerable in some network environments. It is thus important to 2499 control even GET and/or NOTIFY access to these objects and possibly 2500 to even encrypt the values of these objects when sending them over 2501 the network via SNMP. For example, access to network topology and 2502 Rbridge attributes can reveal information that should not be 2503 available to all users of the network. 2505 SNMP versions prior to SNMPv3 did not include adequate security. Even 2506 if the network itself is secure (for example by using IPsec), there 2507 is no control as to who on the secure network is allowed to access 2508 and GET/SET (read/change/create/delete) the objects in this MIB 2509 module. 2511 It is RECOMMENDED that implementers consider the security features as 2512 provided by the SNMPv3 framework (see [RFC3410], section 8), 2513 including full support for the SNMPv3 cryptographic mechanisms (for 2514 authentication and privacy). 2516 Further, deployment of SNMP versions prior to SNMPv3 is NOT 2517 RECOMMENDED. Instead, it is RECOMMENDED to deploy SNMPv3 and to 2518 enable cryptographic security. It is then a customer/operator 2519 responsibility to ensure that the SNMP entity giving access to an 2520 instance of this MIB module is properly configured to give access to 2521 the objects only to those principals (users) that have legitimate 2522 rights to indeed GET or SET (change/create/delete) them. 2524 For other RBridge security considerations see [RFC6325]. 2526 9. IANA Considerations 2528 The MIB module in this document uses the following IANA-assigned 2529 OBJECT IDENTIFIER value recorded in the SMI Numbers registry: 2531 Descriptor OBJECT IDENTIFIER value 2533 ---------- ----------------------- 2535 rbridgeMIB { mib-2 xxx } 2537 Editor's Note (to be removed prior to publication): the IANA is 2538 requested to assign a value for "xxx" under the 'mib-2' subtree and 2539 to record the assignment in the SMI Numbers registry. When the 2540 assignment has been made, the RFC Editor is asked to replace "XXX" 2541 (here and in the MIB module) with the assigned value and to remove 2542 this note. 2544 10.
