Internet-Draft RBridges: TRILL Base MIB September 3, 2010
1. 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.
Zebrose & Rijhsinghani Expires March 7, 2011 [Page 3]
Internet-Draft RBridges: TRILL Base MIB September 3, 2010
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.
Zebrose & Rijhsinghani Expires March 7, 2011 [Page 4]
Internet-Draft RBridges: TRILL Base MIB September 3, 2010
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
Zebrose & Rijhsinghani Expires March 7, 2011 [Page 5]
Internet-Draft RBridges: TRILL Base MIB September 3, 2010
[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:
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.

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.
Zebrose & Rijhsinghani Expires March 7, 2011 [Page 7]
Internet-Draft RBridges: TRILL Base MIB September 3, 2010
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.

8. Security Considerations
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:
o rbridgeBaseNicknameTable
o rbridgeBasePortTable
o rbridgeBaseUniMultipathEnable
o rbridgeVlanTable
o rbridgeVlanPortTable
o rbridgeEsadiTable
o rbridgeDtreePriority
o rbridgeDtreeTable
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
Zebrose & Rijhsinghani Expires March 7, 2011 [Page 46]
Internet-Draft RBridges: TRILL Base MIB September 3, 2010
the network via SNMP.
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
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.
