Introduction + + This document describes a model for managing Routing Bridges + (RBridges), also known as TRILL Switches, as defined in [RFC6325]. + RBridges provide optimal pair-wise forwarding without configuration + using IS-IS routing and encapsulation of traffic. RBridges are + compatible with previous IEEE 802.1 customer bridges as well as IPv4 + and IPv6 routers and end nodes. They are as invisible to current IP + routers as bridges are and, like routers, they terminate the bridge + spanning tree protocol. In creating an RBridge management model, the + device is viewed primarily as a customer bridge. For a discussion of + the problem addressed by TRILL (Transparent Interconnection of Lots + of Links), see [RFC5556]. + + + + +Rijhsinghani & Zebrose Standards Track [Page 2] + +RFC 6850 RBridges: TRILL Base MIB January 2013 + + + RBridges support features specified for transparent bridges in + IEEE 802.1, and the corresponding MIB modules are used to manage + those features. For IS-IS purposes, the corresponding MIB module is + used to manage the protocol. This MIB module specifies those objects + that are TRILL-specific and hence not available in other MIB modules. + +2. The Internet-Standard Management Framework + + 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]. + +3. Overview + + The RBridge MIB module is intended as an overall framework for + managing RBridges, also known as TRILL Switches. Where possible, the + MIB references existing MIB definitions in order to maximize reuse. + This results in a considerable emphasis on the relationship with + other MIB modules. + + Starting with the physical interfaces, there are requirements for + certain elements of the IF-MIB to be implemented. These elements are + required in order to connect the per-port parameters to higher-level + functions of the physical device. + + Transparent bridging, VLANs, traffic classes, and multicast filtering + are supported by the TRILL protocol, and the corresponding management + is expected to conform to the BRIDGE-MIB module [RFC4188] and to the + P-BRIDGE-MIB and Q-BRIDGE-MIB modules [RFC4363]. + + The IS-IS routing protocol is used in order to determine the optimum + pair-wise forwarding path. This protocol is managed using the IS-IS + MIB module defined in [RFC4444]. Since the TRILL protocol specifies + the use of a single level and a fixed area address of zero, some + IS-IS MIB objects are not applicable. Some IS-IS MIB objects are + used in the TRILL protocol. + + + + + + +Rijhsinghani & Zebrose Standards Track [Page 3] + +RFC 6850 RBridges: TRILL Base MIB January 2013 + + +4. Conventions + + The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", + "SHOULD", "SHOULD NOT", "RECOMMENDED", "NOT RECOMMENDED", "MAY", and + "OPTIONAL" in this document are to be interpreted as described in + RFC 2119 [RFC2119]. + +5. Structure of the MIB Module + + Objects in this MIB module are arranged into subtrees. Each subtree + is organized as a set of related objects. The various subtrees are + shown below. These are supplemented with required elements of the + IF-MIB, ISIS-MIB, BRIDGE-MIB, P-BRIDGE-MIB, Q-BRIDGE-MIB, and IEEE + Bridge MIB modules. + +5.1. Textual Conventions + + Textual conventions are defined to represent object types relevant to + TRILL. + +5.2. The rbridgeBase Subtree + + This subtree contains system- and port-specific objects applicable to + all RBridges. + +5.3. The rbridgeFdb Subtree + + This subtree contains objects applicable to the forwarding database + used by the RBridge in making packet-forwarding decisions. Because + it contains additional information used by the TRILL protocol not + applicable to 802.1D/Q bridges, it is a superset of the corresponding + subtrees defined in the BRIDGE-MIB and Q-BRIDGE-MIB. + +5.4. The rbridgeVlan Subtree + + This subtree describes objects applicable to VLANs configured on the + RBridge. + +5.5. The rbridgeEsadi Subtree + + This subtree describes objects relevant to RBridges that support the + optional End-Station Address Distribution Information (ESADI) + protocol. + +5.6. The rbridgeCounters Subtree + + This subtree contains statistics maintained by RBridges that can aid + in monitoring and troubleshooting networks connected by them. + + + +Rijhsinghani & Zebrose Standards Track [Page 4] + +RFC 6850 RBridges: TRILL Base MIB January 2013 + + +5.7. The rbridgeSnooping Subtree + + This subtree describes objects applicable to RBridges capable of + snooping IPv4 and/or IPv6 multicast control frames and pruning IP + multicast traffic based on detection of IP multicast routers and + listeners. + +5.8. The rbridgeDtree Subtree + + This subtree contains objects relevant to distribution trees computed + by RBridges for the forwarding of multi-destination frames. + +5.9. The rbridgeTrill Subtree + + This subtree contains objects applicable to the TRILL IS-IS protocol, + beyond what is available in the ISIS-MIB. + +5.10. The Notifications Subtree + + The defined notifications are focused on the TRILL protocol + functionality. Notifications are defined for changes in the + Designated RBridge status and the topology. + +6. Relationship to Other MIB Modules + + The IF-MIB, BRIDGE-MIB, P-BRIDGE-MIB, Q-BRIDGE-MIB, + IEEE8021-BRIDGE-MIB, IEEE8021-Q-BRIDGE-MIB, and ISIS-MIB modules all + contain objects relevant to the RBridge MIB. Management objects + contained in these modules are not duplicated here, to reduce overlap + to the extent possible. + + The Bridge MIB modules were originally written in the IETF and + implemented by many vendors. Per [RFC4663], this has recently been + transferred to the IEEE 802.1 working group. As vendors may have + implemented either the IETF or IEEE Bridge MIB modules, this RBridge + MIB module is designed to work with either one. + +6.1. Relationship to IF-MIB + + The port identification elements MUST be implemented in order to + allow them to be cross-referenced. The Interfaces MIB [RFC2863] + requires that any MIB module that is an adjunct of the Interfaces MIB + clarify specific areas within the Interfaces MIB module. These areas + were intentionally left vague in the Interfaces MIB module to avoid + over-constraining the MIB, thereby precluding management of certain + media types. Section 4 of [RFC2863] enumerates several areas that a + + + + + +Rijhsinghani & Zebrose Standards Track [Page 5] + +RFC 6850 RBridges: TRILL Base MIB January 2013 + + + media-specific MIB module must clarify. The implementor is referred + to [RFC2863] in order to understand the general intent of these + areas. + +6.2. Relationship to BRIDGE-MIB + + The following subtrees in the BRIDGE-MIB [RFC4188] contain + information relevant to RBridges when the corresponding functionality + is implemented. + + o dot1dBase + + o dot1dTp + + o dot1dStatic + +6.3. Relationship to P-BRIDGE-MIB + + The following subtrees in the P-BRIDGE-MIB [RFC4363] contain + information relevant to RBridges when the corresponding functionality + is implemented. + + o dot1dExtBase + + o dot1dPriority + + o dot1dGarp + + o dot1dGmrp + + o dot1dTpHCPortTable + + o dot1dTpPortOverflowTable + +6.4. Relationship to Q-BRIDGE-MIB + + The following groups in the Q-BRIDGE-MIB [RFC4363] contain + information relevant to RBridges when the corresponding functionality + is implemented. This functionality is also contained in the + IEEE8021-Q-BRIDGE-MIB. + + o dot1qBase + + o dot1qTp + + o dot1qStatic + + + + + +Rijhsinghani & Zebrose Standards Track [Page 6] + +RFC 6850 RBridges: TRILL Base MIB January 2013 + + + o dot1qVlan + + o dot1vProtocol + +6.5. Relationship to IEEE8021-BRIDGE-MIB + + The following subtrees in the IEEE8021-BRIDGE-MIB contain information + relevant to RBridges when the corresponding functionality is + implemented. + + o ieee8021BridgeBase + + o ieee8021BridgeTp + + o ieee8021BridgePriority + + o ieee8021BridgeMrp + + o ieee8021BridgeMmrp + + o ieee8021BridgeInternalLan + + o ieee8021BridgeDot1d + +6.6. Relationship to IEEE8021-Q-BRIDGE-MIB + + The following subtrees in the IEEE8021-Q-BRIDGE-MIB contain + information relevant to RBridges when the corresponding functionality + is implemented. + + o ieee8021QBridgeBase + + o ieee8021QBridgeTp + + o ieee8021QBridgeStatic + + o ieee8021QBridgeVlan + + o ieee8021QBridgeProtocol + + + + + + + + + + + + +Rijhsinghani & Zebrose Standards Track [Page 7] + +RFC 6850 RBridges: TRILL Base MIB January 2013 + + +6.7. Relationship to ISIS-MIB + + "Management Information Base for Intermediate System to Intermediate + System (IS-IS)" [RFC4444] defines a MIB module for the IS-IS routing + protocol when it is used to construct routing tables for IP networks. + While most of these objects are applicable to the TRILL layer 2 + implementation, note the IS-IS constraints for the current version of + TRILL [RFC6325]: + + o The TRILL IS-IS instance uses a single Level 1 IS-IS area. + + o The TRILL Level 1 IS-IS area uses the fixed area address zero. + + o The TRILL IS-IS instance is not used for IP address advertisement. + + o The TRILL IS-IS instance is used for only a single protocol: + TRILL. + + Accordingly, tables that report IP address reachability and tables + that allow configuration or reporting of multiple IS-IS areas, + multiple IS-IS levels, or multiple protocols will be empty in the + ISIS-MIB module for the current version of TRILL. + + Note also that when more than one instance of the IS-IS protocol is + running on a device, as in the case of a device performing both + RBridge and IS-IS IP router functions, multiple instances of the + ISIS-MIB module can be distinguished by the use of SNMPv3 contexts or + SNMPv1 communities. + +6.8. MIB Modules Required for IMPORTS + + The following MIB module imports objects from the SNMPv2-SMI + [RFC2578], SNMPv2-TC [RFC2579], SNMPv2-CONF [RFC2580], IF-MIB + [RFC2863], INET-ADDRESS-MIB [RFC4001], BRIDGE-MIB [RFC4188], + and Q-BRIDGE-MIB [RFC4363].

Security Considerations + + This MIB relates to a system that will provide network connectivity + and packet-forwarding services. As such, improper manipulation of + the objects represented by this MIB may result in denial of service + to a large number of end-users. + + There are a number of management objects defined in this MIB module + with 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. These are the tables and objects and their + sensitivity/vulnerability: + + The following tables and objects in the RBRIDGE-MIB can be + manipulated to interfere with the operation of RBridges: + + o rbridgeBaseUniMultipathEnable affects the ability of the RBridge + to route unicast traffic over multiple paths, and + rbridgeBaseMultiMultipathEnable affects the ability of the RBridge + to route multi-destination traffic over multiple paths. + + o rbridgeBasePortTable contains a number of objects that may affect + network connectivity. Actions that may be triggered by + manipulating objects in this table include disabling of an RBridge + port, discarding of native packets, disabling learning, and + others. + + o rbridgeEsadiTable contains objects that affect the operation of + the ESADI protocol used for learning, and manipulation of the + objects contained therein can be used to confuse the learning + ability of RBridges. + + o rbridgeDtreePriority can affect computation of distribution trees + within an RBridge campus, thereby affecting the forwarding of + multi-destination traffic. + + o rbridgeTrillMinMtuDesired can affect the size of packets being + used to exchange information between RBridges. + + Some of the readable objects in this MIB module (i.e., objects with a + MAX-ACCESS other than not-accessible) may be considered sensitive or + vulnerable in some network environments. It is thus important to + control even GET and/or NOTIFY access to these objects and possibly + to even encrypt the values of these objects when sending them over + + + + + +Rijhsinghani & Zebrose Standards Track [Page 55] + +RFC 6850 RBridges: TRILL Base MIB January 2013 + + + the network via SNMP. For example, access to network topology and + RBridge attributes can reveal information that should not be + available to all users of the network. + + SNMP versions prior to SNMPv3 did not include adequate security. + Even if the network itself is secure (for example by using IPsec), + 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 module. + + Implementations SHOULD provide the security features described by the + SNMPv3 framework (see [RFC3410]), and implementations claiming + compliance to the SNMPv3 standard MUST include full support for + authentication and privacy via the User-based Security Model (USM) + [RFC3414] with the AES cipher algorithm [RFC3826]. Implementations + MAY also provide support for the Transport Security Model (TSM) + [RFC5591] in combination with a secure transport such as SSH + [RFC5592] or TLS/DTLS [RFC6353]. + + Further, deployment of SNMP versions prior to SNMPv3 is NOT + RECOMMENDED. Instead, it is RECOMMENDED to deploy SNMPv3 and to + enable cryptographic security. It is then a customer/operator + responsibility to ensure that the SNMP entity giving access to an + instance of this MIB module 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. + + For other RBridge security considerations, see [RFC6325]. + +9.
