In particular, it describes managed objects to configure and/or monitor Multi-protocol Label Switching Layer-3 Virtual Private Networks on a Multi-Protocol Label Switching (MPLS) Label Switching Router (LSR) supporting this feature. Comments should be made directly to the MPLS mailing list at mpls@uu.net and the Layer-3 VPN (L3VPN) WG at l3vpn@ietf.org. 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, reference [RFC2119]. 3.0 Terminology This document uses terminology from the document describing the MPLS architecture [MPLSArch] and from the document describing MPLS Layer-3 VPNs (L3VPN) [MPLSBGPVPN], as well as the MPLS architecture [RFC3031]. Throughout this document, the use of the terms "Provider Edge (PE) IETF L3 Working Group Expires August 2004 [Page 2]
Internet Draft MPLS L3 VPN MIB February 03, 2004 and Customer Edge (CE) or PE/CE" will be replaced by PE in all cases except when a network device is a CE when used in the carrier of carriers model. 4.0 The SNMP 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]. 5.0 Assumptions and Prerequisites It is assumed that certain things are configured and operational in order for the tables and objects described in this MIB to function correctly. These things are outlined below: - MPLS in general, must be configured and operational. - LDP paths or traffic engineered tunnels should be configured between PEs and CEs. 6.0 Brief Description of MIB Objects The following subsections describe the purpose of each of the objects contained in the MPLS-VPN-MIB. 6.1 mplsL3VpnVrfTable This table represents the MPLS L3VPNs that are configured. A Network Management System (NMS) or SNMP agent creates an entry in this table for every MPLS L3VPN configured on the LSR being examined. The VPR that is configured at a particular device represents an instance of some VPN, but not the entire VPN (unless it is the only VRF, of course). The collective set of VRF instances comprises the actual VPN. This information is typically only known in its entirety at the NMS. That is, specific devices generally only know of their local VRF information, but not that of other LSRs' VRFs. IETF L3 Working Group Expires August 2004 [Page 3]
Internet Draft MPLS L3 VPN MIB February 03, 2004 6.2 mplsL3VpnIfConfTable This table represents the MPLS L3VPN-enabled interfaces that are associated with a specific VRF as represented in the aforementioned mplsL3VpnVrfTable. Each entry in this table corresponds to an entry in the Interfaces MIB. In addition, each entry extends its corresponding entry in the Interface MIB to contain specific MPLS L3VPN information. Due to this correspondence, certain objects such as traffic counters are not found in this MIB to avoid overlap, but instead are found in the Interfaces MIB [RFC2863]. 6.3 mplsL3VpnVrfPerfTable This table contains objects to measure the performance of MPLS L3VPNs and augments the mplsL3VpnVrfConfTable. High capacity counters are provided for objects that are likely to wrap around quickly on objects such as high-speed interface counters. 6.4 mplsL3VpnVrfRouteTable The table contains the objects necessary to configure and monitor routes used by a particular VRF. This includes a cross-connect pointer into the MPLS-LSR-STD-MIB's mplsXCTable, which may be used to refer that entry to its label stack used to label switch that entry. 6.5 MplsVpnVrfRTTable The table contains the objects necessary to configure and monitor route targets for a particular VRF. 7.0 Example of MPLS L3VPN Setup In this section, we provide a brief example of using the MIB objects described in the following section. While this example is not meant to illustrate every nuance of the MIB, it is intended as an aid to understanding some of the key concepts. It is our intent that it is read only after the reader has gone through the MIB itself. This configuration is under the assumption that 1) MPLS has been pre- configured in the network, through enabling LDP or RSVP-TE. 2) OSPF or ISIS has been pre-configured. 3) BGP sessions have been established between PEs.

This MIB module can also be used for configuration of certain objects, and anything that can be configured can be incorrectly configured, with potentially disastrous results. 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: o the mplsL3VpnVrfRouteTable, mplsL3VpnIfConfTable and mplsL3VpnVrfTable tables collectively contain objects which may be used to provision MPLS VRF interfaces and configuration. Unauthorized access to objects in these tables, could result in disruption of traffic on the network. This is especially true if these VRFs have been previously provisioned and are in use. The use of stronger mechanisms such as SNMPv3 security should be considered where possible. Specifically, SNMPv3 VACM and USM MUST be used with any v3 agent which implements this MIB module. Administrators should consider whether read access to these objects should be allowed, since read access may be undesirable under certain circumstances. 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 IETF L3 Working Group Expires August 2004 [Page 34]
Internet Draft MPLS L3 VPN MIB February 03, 2004 the network via SNMP. These are the tables and objects and their sensitivity/vulnerability: o the mplsL3VpnVrfTable, mplsL3VpnIfConfTable tables collectively show the VRF interfaces and associated VRF configurations as well as their linkages to other MPLS-related configuration and/or performanc statistics. Administrators not wishing to reveal this information should consider these objects sensitive/vulnerable and take precautions so they are not revealed. 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. 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. 17. Intellectual Property Notice The IETF takes no position regarding the validity or scope of any intellectual property or other rights that might be claimed to pertain to the implementation or use of the technology described in this document or the extent to which any license under such rights might or might not be available; neither does it represent that it has made any effort to identify any such rights. Information on the IETF's procedures with respect to rights in standards-track and standards-related documentation can be found in BCP-11 [RFC2028]. Copies of claims of rights made available for publication and any assurances of licenses to be made available, or the result of an attempt made to obtain a general license or permission for the use of such proprietary rights by implementors or users of this specification can be obtained from the IETF Secretariat.

IANA Considerations As described in [MPLSMGMT] and as requested in the MPLS-TC-STD-MIB [MPLSTCMIB], MPLS related standards track MIB modules should be rooted under the mplsStdMIB subtree. There is one MPLS-related MIB module contained in this document. Each of the following "IANA Considerations" subsections requests IANA for a new assignment under the mplsStdMIB subtree. New assignments can only be made via a Standards Action as specified in [RFC2434]. 18.1. IANA Considerations for MPLS-L3VPN-MIB The IANA is requested to assign { mplsStdMIB 8 } to the MPLS-L3VPN-MIB module specified in this document. IETF L3 Working Group Expires August 2004 [Page 36]
