1. Introduction

This document describes a model for managing RBridges (Routing
Bridges), 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 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) 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
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,
which consists of
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 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 higher-level
functions of the physical device.

Transparent bridging, VLANs, Traffic classes traffic classes, and Multicast Filtering multicast filtering
are supported by the TRILL protocol, and the corresponding management
is expected to conform to the BRIDGE-MIB [RFC4188], module [RFC4188] and to the
P-BRIDGE-MIB and Q-BRIDGE-MIB [RFC4363] modules. 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,
IF-MIB, ISIS-MIB, BRIDGE-MIB, P-BRIDGE-MIB, Q-BRIDGE-MIB Q-BRIDGE-MIB, and IEEE
Bridge MIB modules.

5.1

5.1. Textual Conventions

Textual conventions are defined to represent object types relevant to
TRILL.

5.2

5.2. The rbridgeBase Subtree

This subtree contains system system- and port specific port-specific objects applicable to
all RBridges.

5.3

5.3. The rbridgeFdb Subtree

This subtree contains objects applicable to the Forwarding forwarding database
used by the RBridge in making packet forwarding 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

5.4. The rbridgeVlan subtree Subtree

This subtree describes objects applicable to VLANs configured on the
RBridge.

5.5

5.5. The rbridgeEsadi subtree Subtree

This subtree describes objects relevant to RBridges that support the
optional ESADI End-Station Address Distribution Information (ESADI)
protocol.

5.6

5.6. The rbridgeCounters subtree Subtree

This subtree contains statistics maintained by RBridges that can aid
in monitoring and troubleshooting networks connected by them.

5.7

5.7. The rbridgeSnooping subtree Subtree

This subtree describes objects applicable to RBridges capable of
snooping IPv4 and/or IPv6 Multicast multicast control frames and pruning IP
multicast traffic based on detection of IP multicast routers and
listeners.

5.8

5.8. The rbridgeDtree subtree Subtree

This subtree contains objects relevant to Distribution Trees distribution trees computed
by RBridges for the forwarding of multi-destination frames.

5.9

5.9. The rbridgeTrill subtree Subtree

This subtree contains objects applicable to the TRILL IS-IS protocol,
beyond what is available in the ISIS-MIB.

5.10

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
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, 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

6.1. Relationship to IF-MIB

The port identification elements MUST be implemented in order to
allow them to be cross referenced. cross-referenced. The Interface Interfaces MIB [RFC2863]
requires that any MIB module which that is an adjunct of the Interface Interfaces MIB
clarify specific areas within the Interface Interfaces MIB module. These areas
were intentionally left vague in the Interface Interfaces MIB module to avoid
over-constraining the MIB, thereby precluding management of certain
media types. Section 4 of [RFC2863] enumerates several areas which that 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

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 ieee8021QBridgeVlan

o ieee8021QBridgeProtocol

6.7

6.7. Relationship to ISIS-MIB

The Management

"Management Information Base for Intermediate System to Intermediate
System (IS-IS)[RFC4444] (IS-IS)" [RFC4444] defines a MIB module for the IS-
IS Routing 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 that report IP address reachability and tables
which
that allow configuration or reporting of multiple IS-IS areas,
multiple IS-IS levels levels, or multiple protocols, 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

6.8. MIB modules required Modules Required for IMPORTS

The following MIB module IMPORTS imports objects from the SNMPv2-SMI
[RFC2578], SNMPv2-TC [RFC2579], SNMPv2-CONF [RFC2580], IF-MIB
[RFC2863],
INET-ADDRESS-MIB[RFC4001], BRIDGE-MIB[RFC4188] INET-ADDRESS-MIB [RFC4001], BRIDGE-MIB [RFC4188],
and
Q-BRIDGE-MIB[RFC4363]. Q-BRIDGE-MIB [RFC4363]. (The IEEE Bridge MIB modules import
similar TCs.)

8. Security Considerations

This MIB relates to a system which that will provide network connectivity
and packet forwarding 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 are described below.
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
multipath route unicast traffic, traffic over multiple paths, and
rbridgeBaseMultiMultipathEnable affects the ability of the Rbridge RBridge
to multipath route multi-destination
traffic. 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;
port, discarding of native packets; packets, disabling learning 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. RBridges.

o rbridgeDtreePriority can affect computation of distribution trees
within an Rbridge RBridge campus, thereby affecting the forwarding of multi-
destination
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
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

Implementations SHOULD provide the security features as
provided described by the
SNMPv3 framework (see [RFC3410], section 8),
including [RFC3410]), and implementations claiming
compliance to the SNMPv3 standard MUST include full support for the SNMPv3 cryptographic mechanisms (for
authentication and privacy). 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 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 214 }

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.
