1. Introduction
This memo defines a portion of the Management Information Base (MIB)
for use with network management protocols in the Internet community.
In particular, it describes managed objects to configure and/or
monitor Multiprotocol Label Switching Layer-3 Virtual Private
Networks on a Multi-Protocol Label Switching (MPLS) Label Switching
Router (LSR) supporting this feature.
This document adopts the definitions, acronyms, and mechanisms
described in [RFC4364]. Unless otherwise stated, the mechanisms of
[RFC4364] apply and will not be re-described here.
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 [RFC2119].
Nadeau & van Der Linde Standards Track [Page 2]
RFC 4382 MPLS-L3VPN-STD-MIB February 2006
2. Terminology
This document uses terminology from the document describing the MPLS
architecture [RFC3031] and from the document describing MPLS Layer-3
VPNs (L3VPN) [RFC4364], as well as the MPLS architecture [RFC3031].
Throughout this document, the use of the terms "Provider Edge (PE)
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's
carrier model.
3. 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].
4. 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.
- Label Distribution Protocol (LDP) paths or traffic-engineered
tunnels [RFC3812] should be configured between PEs and CEs.
5. Brief Description of MIB Objects
The following subsections describe the purpose of each of the
objects contained in the MPLS-L3VPN-STD-MIB.
5.1. 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 Virtual Routing and Forwarding (VRF) that is
Nadeau & van Der Linde Standards Track [Page 3]
RFC 4382 MPLS-L3VPN-STD-MIB February 2006
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.
5.2. 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 Interfaces 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].
5.3. mplsL3VpnVrfPerfTable
This table contains objects to measure the performance of MPLS
L3VPNs and augments the mplsL3VpnVrfTable. High capacity counters
are provided for objects that are likely to wrap around quickly on
objects such as high-speed interface counters.
5.4. 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.
5.5. MplsVpnVrfRTTable
The table contains the objects necessary to configure and monitor
route targets for a particular VRF.
6. 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.
Nadeau & van Der Linde Standards Track [Page 4]
RFC 4382 MPLS-L3VPN-STD-MIB February 2006
This configuration is under the assumption that 1) MPLS has been
pre-configured in the network, through enabling LDP or Resource
Reservation Protocol - Traffic Engineering (RSVP-TE); 2) OSPF or
Intermediate System to Intermediate System (IS-IS) has been pre-
configured; and 3) BGP sessions have been established between PEs.
Defining the VRF, the route target, and route distinguisher:
In mplsL3VpnVrfTable:
{
mplsL3VpnVrfName = "RED",
mplsL3VpnVrfDescription = "Intranet of Company ABC",
mplsL3VpnVrfRD = "100:1", -- octet string
mplsL3VpnVrfRowStatus = createAndGo(4)
}
In mplsL3VpnVrfRouteTable:
{
mplsL3VpnVrfRTRowStatus."Red"."100:1".import = createAndGo,
mplsL3VpnVrfRTRowStatus."Red"."100:1".export = createAndGo
}

continuous generation of notifications by an agent in the event
that routes are continually added to a VRF after it has reached
its maximum value. If this value is set to 0, the agent should
only issue a single notification at the time that the maximum

which the mplsNumVrfRouteMaxThreshExceeded notification will
be reissued after the maximum value has been exceeded (or
reached if mplsL3VpnVrfConfMaxRoutes and
mplsL3VpnVrfConfHighRteThresh are equal) and the initial
notification has been issued. Therefore,
the generation of this notification should also be emitted with
this same frequency (assuming that the error condition is
cleared). Specifically, if the error condition is reached and
cleared several times during the period of time specified in
mplsL3VpnVrfConfRteMxThrshTime, only a single notification will
be issued to indicate the first instance of the error condition
as well as the first time the error condition is cleared.
This behavior is intended to prevent continuous generation of
notifications by an agent in the event that routes are
continually added and removed to/from a VRF after it has
reached its maximum value. The default value is 0. If this
value is set to 0, the agent should issue a notification
whenever the maximum threshold has been cleared."

8. Security Considerations
It is clear that these MIB modules are potentially useful for
monitoring of MPLS LSRs supporting L3 MPLS VPN. 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 that 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.
Nadeau & van Der Linde Standards Track [Page 38]
RFC 4382 MPLS-L3VPN-STD-MIB February 2006
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 that 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
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 performance 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.

9. IANA Considerations
As described in MPLS-TC-STD-MIB [RFC3811], MPLS related standards
track MIB modules should be rooted under the mplsStdMIB subtree.
There is one MPLS-related MIB module contained in this document. The
following subsection requests IANA for a new assignment under the
mplsStdMIB subtree. New assignments can only be made via a Standards
Action as specified in [RFC2434].
9.1. IANA Considerations for MPLS-L3VPN-STD-MIB
The IANA has assigned { mplsStdMIB 11 } to the MPLS-L3VPN-STD-MIB
module specified in this document.
10. Dedication
