1.  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.

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.

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

  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].  (The IEEE Bridge MIB modules import
  similar TCs.)

8.  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

  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.  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-2 214 }
