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 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.

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)

[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.
