Introduction This document describes a model for managing RBridges as defined in [RBridge]. 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 see [RFC5556]. RBridges support features specified for transparent bridges in IEEE 802.1, and the corresponding MIBs are used to manage those features. For IS-IS purposes, the corresponding MIB is used to manage the protocol. This MIB specifies those objects which are TRILL-specific and hence not available in other MIBs. 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 is intended as an overall framework for managing RBridges. 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 documents. 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 [RFC4188], P-BRIDGE-MIB and Q-BRIDGE-MIB [RFC4363] modules. Rijhsinghani & Zebrose Expires September 3, 2011 [Page 3] Internet-Draft RBridges: TRILL Base MIB March 2, 2011 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 defined in [RFC4444]. Since the TRILL protocol specifies use of a single level and a fixed area address of zero, some 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", "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 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 and Q-BRIDGE-MIB. 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 ESADI protocol. Rijhsinghani & Zebrose Expires September 3, 2011 [Page 4] Internet-Draft RBridges: TRILL Base MIB March 2, 2011 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. TBD for this section is what notifications are required from imported MIBs and how can the TRILL notifications be throttled. 6. Relationship to Other MIB Modules The IF-MIB, BRIDGE-MIB, P-BRIDGE-MIB, Q-BRIDGE-MIB, and ISIS-MIB 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. 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. These areas were intentionally left vague in the Interface MIB 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 must clarify. The implementor is referred to Rijhsinghani & Zebrose Expires September 3, 2011 [Page 5] Internet-Draft RBridges: TRILL Base MIB March 2, 2011 [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. This functionality is also contained in IEEE8021- BRIDGE-MIB. 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. This functionality is also contained in IEEE8021- BRIDGE-MIB. 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 6.5 Relationship to IS-IS MIB The Management Information Base for Intermediate System to Intermediate System (IS-IS)[RFC4444] defines a MIB for the IS-IS Routing protocol when it is used to construct routing tables for IP networks. While most of these objects are directly applicable to the TRILL layer 2 implementations there are some modifications detailed below. Rijhsinghani & Zebrose Expires September 3, 2011 [Page 6] Internet-Draft RBridges: TRILL Base MIB March 2, 2011 System-Wide Attributes isisSystem - This table contains information specific to a single instance of the IS-IS protocol. The TRILL IS-IS implementation follows the IS-IS MIB except for the following changes: isisLevelType MUST read level 1 The TRILL IS-IS implementation does not include Level 2. isisSysProtSupport MUST read zero The IP protocols detailed in the IS-IS MIB are not applicable. isisSysL2toL2Leaking MUST read FALSE The TRILL IS-IS implementation does not include Level 2. isisManAreaAddr - This subtree is not implemented in TRILL IS-IS. TRILL IS-IS uses a single fixed area address of zero. isisAreaAddr - This subtree is not implemented in TRILL IS-IS. TRILL IS-IS uses a single fixed area address of zero. isisSummAddr - This subtree is not implemented in TRILL IS-IS. In IS-IS this table holds summary addresses configured for each Level 2 instance of the IS-IS protocol running on a router. TRILL does not implement Level 2. isisRedistributeAddr - This subtree is not implemented in TRILL IS-IS. In IS-IS this table is used to implement Level2 to Level1 address leaking. TRILL does not implement Level 2. isisRouter - This table is implemented. This table holds the System ID for Intermediate Systems in the campus. Rijhsinghani & Zebrose Expires September 3, 2011 [Page 7] Internet-Draft RBridges: TRILL Base MIB March 2, 2011 Rijhsinghani & Zebrose Expires September 3, 2011 [Page 8] Internet-Draft RBridges: TRILL Base MIB March 2, 2011 isisSysLevel - This table is implemented. This table contains information specific to a domain (Level 2) or an area (Level 1) of the IS-IS protocol. In the case of TRILL IS-IS there is only one entry in the table for Level 1 area zero. isisNextCircIndex - This scalar is implemented. This scalar is used to provide a unique circuit index. Circuit-specific Attributes isisCirc - This table is implemented, with the following modification. This table contains information specific to a point-to-point or a broadcast interface in the system. isisCircLevelType MUST read level1 isisCircLevelIndex MUST read level1 Counters isisSystemCounter - This table is implemented. Counters in the System table, such as number of times we have wrapped a sequence counter on one of our Link State PDUs. isisCircuitCounter - This table is implemented. Counters of events particular to a circuit, such as PDUs with an illegal value of the System ID field length. isisPacketCounter - This table is implemented.

Entries in this table cannot be created by management action: they are established through the Hello protocol. isisISAdjAreaAddr - This table is not implemented. This table contains the set of Area Addresses of neighboring Intermediate Systems, as reported in IIH PDUs. Since all area addresses are zero there is no need for a table. isisISAdjIPAddr - This table is not implemented. This table contains the set of IP Addresses of neighboring Intermediate Systems, as reported in received IIH PDUs. The table has been replaced by addition of the RBridgeISAdjMACAddr in the RBridge subtree. isisISAdjProtSupp - This table is not implemented. This table contains the set of protocols supported by neighboring Intermediate Systems, as reported in received IIH PDUs. Attributes Associated with Addresses isisRA - This table is implemented. The Reachable Address Table. Normally each entry defines a configured Reachable Address to an NSAP or Address Prefix. In the case of an RBridge the unique isisRAIndex should be defined as type MacAddress rather than an Unsigned32. isisIPRA - This table is not implemented. The IP Reachable Address Table. This table contains information about an IP reachable address manually configured on this system or learned from another protocol.

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. The following tables and objects in the RBRIDGE-MIB can be manipulated to interfere with the operation of RBridges: Rijhsinghani & Zebrose Expires September 3, 2011 [Page 48] Internet-Draft RBridges: TRILL Base MIB March 2, 2011 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 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 Rijhsinghani & Zebrose Expires September 3, 2011 [Page 49] Internet-Draft RBridges: TRILL Base MIB March 2, 2011 rights to indeed GET or SET (change/create/delete) them. For other RBridge security considerations see [RBridge]. 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.
