Introduction This document describes a model for managing RBridges (Routing Bridges), 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]. 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 which 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, which consists of [RFC2578], [RFC2579] and [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 Rijhsinghani & Zebrose Expires June 6, 2013 [Page 3] Internet-Draft RBridges: TRILL Base MIB December 3, 2012 are supported by the TRILL protocol, and the corresponding management is expected to conform to the BRIDGE-MIB [RFC4188], P-BRIDGE-MIB and Q-BRIDGE-MIB [RFC4363] modules. 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 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. 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. Rijhsinghani & Zebrose Expires June 6, 2013 [Page 4] Internet-Draft RBridges: TRILL Base MIB December 3, 2012 5.5 The rbridgeEsadi subtree This subtree describes objects relevant to RBridges that support the optional 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. 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 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 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. Rijhsinghani & Zebrose Expires June 6, 2013 [Page 5] Internet-Draft RBridges: TRILL Base MIB December 3, 2012 6.1 Relationship to IF-MIB The port identification elements MUST be implemented in order to allow them to be cross referenced. The Interface MIB [RFC2863] requires that any MIB module which is an adjunct of the Interface MIB clarify specific areas within the Interface MIB module. These areas were intentionally left vague in the Interface MIB module to avoid over-constraining the MIB, thereby precluding management of certain media types. Section 4 of [RFC2863] enumerates several areas which a 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 IEEE8021-Q- BRIDGE-MIB. o dot1qBase o dot1qTp o dot1qStatic o dot1qVlan o dot1vProtocol Rijhsinghani & Zebrose Expires June 6, 2013 [Page 6] Internet-Draft RBridges: TRILL Base MIB December 3, 2012 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 6.7 Relationship to ISIS-MIB The 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 which report IP address reachability and tables which 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. Rijhsinghani & Zebrose Expires June 6, 2013 [Page 7] Internet-Draft RBridges: TRILL Base MIB December 3, 2012 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 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 which 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 tables and objects and their sensitivity/vulnerability are described below. Rijhsinghani & Zebrose Expires June 6, 2013 [Page 52] Internet-Draft RBridges: TRILL Base MIB December 3, 2012 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 multipath unicast traffic, and rbridgeBaseMultiMultipathEnable affects the ability of the Rbridge to multipath multi-destination traffic. 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 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 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. It is RECOMMENDED that implementers consider the security features as provided by the SNMPv3 framework (see [RFC3410], section 8), including full support for the SNMPv3 cryptographic mechanisms (for authentication and privacy). 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 Rijhsinghani & Zebrose Expires June 6, 2013 [Page 53] Internet-Draft RBridges: TRILL Base MIB December 3, 2012 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. IANA Considerations The MIB module in this document uses the following IANA-assigned OBJECT IDENTIFIER value recorded in the SMI Numbers registry: Descriptor OBJECT IDENTIFIER value ---------- ----------------------- rbridgeMIB { mib-2 xxx } Editor's Note (to be removed prior to publication): the IANA is requested to assign a value for "xxx" under the 'mib-2' subtree and to record the assignment in the SMI Numbers registry. When the assignment has been made, the RFC Editor is asked to replace "XXX" (here and in the MIB module) with the assigned value and to remove this note. 10.
