1. 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].
2. Introduction
The OSPF MIB was originally defined for OSPF version 2 in support of
IPv4 [RFC4750] and extended to support the Internet Protocol
version 6 (IPv6) as OSPF version 3 MIB [RFC5643]. The IS-IS MIB is
also defined in [RFC4444]. On the other side, MPLS-/GMPLS-based
traffic engineering has so far extended the OSPF/IS-IS routing
protocol with TE functionality [RFC4202] [RFC3630] [RFC5329]
[RFC5307] [RFC5305]. To manage such MPLS-TE/GMPLS networks
Miyazawa, et al. Standards Track [Page 3]
RFC 6825 TED MIB for MPLS-TE/GMPLS January 2013
effectively, routing information associated with MPLS/GMPLS TE
parameters is preferred for network management; however, there is no
clear definition of MPLS/GMPLS TE information in existing MIBs
related to OSPF(v2 and v3)/IS-IS.
This memo defines the MIB objects for managing TED in support of
MPLS-TE/GMPLS for use with network management protocols.
This MIB module should be used in conjunction with the OSPFv2 MIB,
OSPF v3 MIB, and IS-IS MIB, as well as other MIBs defined in
[RFC3812], [RFC3813], [RFC4802], and [RFC4803] for the management of
MPLS-/GMPLS-based traffic engineering information. By implementing
such MIB modules, it is helpful to simultaneously understand the
entire MPLS/GMPLS network, for example, understanding routing
information as well as LSP information using a management system.
However, note that this MIB module is able to be implemented and
performed without implementation of other MIB modules when the
management system, for example, only comprehends MPLS/GMPLS topology
information such as TE link information.
3. Overview
3.1. Conventions Used in This Document
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].
3.2. Terminology
Definitions of key terms for MPLS Operations, Administration, and
Maintenance (OAM) and GMPLS are found in [RFC4377] and [RFC3945], and
the reader is assumed to be familiar with those definitions, which
are not repeated here.

3.3. Acronyms
GMPLS: Generalized Multiprotocol Label Switching
IS-IS: Intermediate System to Intermediate System
LSA: Link State Advertisement
LSP: Label Switching Path
LSR: Label Switching Router
MIB: Management Information Base
OSPF: Open Shortest Path First
PSC: Packet Switch Capable
SRLG: Shared Risk Link Group
TE: Traffic Engineering
TED: Traffic Engineering Database
TDM: Time Division Multiplexing
4. Motivations
The existing OSPFv2, OSPFv3, IS-IS, MPLS, and GMPLS MIBs do not
provide for the management interface to retrieve topology information
of MPLS and GMPLS networks.
5. Brief Description of MIB Module
The objects described in this section support the management of TED
as described in [RFC4202], [RFC4203], and [RFC5307] for GMPLS
extensions as well as in [RFC3630] and [RFC5305] for MPLS/GMPLS.
5.1. tedTable
The TED table is basically used to indicate TED information of OSPF-
TE or ISIS-TE. However, this table does not contain information for
the Local/Remote Interface IP Address, Interface Switching Capability
Descriptor, or Shared Risk Link Group information within the sub-TLVs
for the Link-TLV.
5.2. tedLocalIfAddrTable
The tedLocalIfAddrTable is identical to the Local Interface IP
Address information in a sub-TLV for the Link-TLV. This is
independently defined, because the Interface IP Address sub-TLV may
appear more than once with the same Link-TLV.
5.3. tedRemoteIfAddrTable
The tedRemoteIfAddrTable is identical to the Remote Interface IP
Address information in a sub-TLV of the Link-TLV. This is
independently defined, because the Interface IP Address sub-TLV may
appear more than once with the same Link-TLV.
Miyazawa, et al. Standards Track [Page 5]
RFC 6825 TED MIB for MPLS-TE/GMPLS January 2013
5.4. tedSwCapTable
The tedSwCapTable is identical to the Interface Switching Capability
Descriptor information in a sub-TLV of the Link-TLV. This is
independently defined, because the Interface Switching Capability
Descriptor sub-TLV may appear more than once with the same Link-TLV.
5.5. tedSrlgTable
The tedSrlgTable is identical to the Shared Risk Link Group
information in a sub-TLV of the Link-TLV. This table is
independently defined because the Shared Risk Link Group sub-TLV may
appear more than once with the same Link-TLV.
6. Example of the TED MIB Module Usage
In this section, we provide an example of the TED MIB module usage.
The following indicates the information of a numbered TE link
originated in a GMPLS-controlled node. When TE link information is
retrieved in an MPLS network, GMPLS-specific objects such as
tedLocalIfAddrTable, tedRemoteIfAddrTable, tedSwCapTable, and
tedSrlgTable are not supported.
By retrieval of such information periodically, the management system
can comprehend the detailed topology information related to
MPLS/GMPLS networks. In particular, the basic TED information can be
collected by tedTable, and Local/Remote Interface IP Address
information related to MPLS/GMPLS networks are collected by
tedLocalIfAddrTable and tedRemoteIfAddrTable, and the attribute
information related to GMPLS TE links can be retrieved by
tedSwCapTable and tedSrlgTable. Regarding fault management, there is
no functionality to notify network failures in this MIB module.
However, if network topologies are changed, the module can notify the
management system of the change information by using tedStatusChange,
tedEntryCreated, and tedEntryDeleted.
Note that the TED MIB module is limited to "read-only" access except
for tedCreatedDeletedNotificationMaxRate and
tedStatusChangeNotificationMaxRate. The TED MIB module is designed
to be independent of OSPF or IS-IS MIBs; however, information for
each TE link belongs to a node or a link that is managed by the
routing protocol.

8. Security Considerations
There are several objects defined in this MIB module that have a MAX-
ACCESS clause of read-write. 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.
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. These are the tables and objects and their
sensitivity/vulnerability: tedTable, tedLocalIfAddrTable,
tedRemoteIfAddrTable, tedSwCapTable, and tedSrlgTable contain
topology information for the MPLS/GMPLS network. If an administrator
does not want to reveal this information, then these tables should be
considered sensitive/vulnerable.
There are only two write-access objects in this MIB module:
tedStatusChangeNotificationMaxRate and
tedCreatedDeletedNotificationMaxRate. Malicious modification of
these objects could cause the management agent, the network, or the
router to become overloaded with notifications in cases of high churn
within the network.
SNMP versions prior to SNMPv3 did not include adequate security.
Even if the network itself is secure (for example by using IPsec),
even then, 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 MUST provide the security features described by the
SNMPv3 framework (see [RFC3410]), including full support for
authentication and privacy via the User-based Security Model (USM)
Miyazawa, et al. Standards Track [Page 35]
RFC 6825 TED MIB for MPLS-TE/GMPLS January 2013
[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.
9. IANA Considerations
IANA has assigned 273 to the TED-MIB module specified in this
document in the "Internet-standard MIB - Transmission Group"
registry. New assignments can only be made via Specification
Required as specified in [RFC5226].
In addition, the IANA has marked value 273 (the corresponding
transmission value allocated according to this document) as
"Reserved" in the "ifType definitions" registry.
