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 for modeling Generalized
Multiprotocol Label Switching (GMPLS) [RFC 3945] based traffic
engineering (TE). The tables and objects defined in this document
extend those defined in the equivalent document for MPLS traffic
engineering [RFC 3812], and management of GMPLS traffic engineering is
built on management of MPLS traffic engineering.
The MIB modules in this document should be used in conjunction with
the companion document [RFC 4803] for GMPLS-based traffic engineering
configuration and management.
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 BCP 14, [RFC 2119].
Nadeau & Farrel Standards Track PAGE 2
RFC 4802 GMPLS TE MIB February 2007
1.1. Migration Strategy
MPLS-TE Label Switched paths (LSPs) may be modeled and managed using
the MPLS-TE-STD-MIB module [RFC 3812].
Label Switching Routers (LSRs) may be migrated to model and manage
their TE LSPs using the MIB modules in this document in order to
migrate the LSRs to GMPLS support, or to take advantage of additional
MIB objects defined in these MIB modules that are applicable to
MPLS-TE.
The GMPLS TE MIB module (GMPLS-TE-STD-MIB) defined in this document
extends the MPLS-TE-STD-MIB module [RFC 3812] through a series of
augmentations and sparse augmentations of the MIB tables. The only
additions are for support of GMPLS or to support the increased
complexity of MPLS and GMPLS systems.
In order to migrate from MPLS-TE-STD-MIB support to GMPLS-TE-STD-MIB
support, an implementation needs only to add support for the
additional tables and objects defined in GMPLS-TE-STD-MIB. The
gmplsTunnelLSPEncoding may be set to tunnelLspNotGmpls to allow an
MPLS-TE LSP tunnel to benefit from the additional objects and tables
of GMPLS-LSR-STD-MIB without supporting the GMPLS protocols.
The companion document for modeling and managing GMPLS-based LSRs
[RFC 4803] extends the MPLS-LSR-STD-MIB module [RFC 3813] with the same
intentions.
Textual conventions are defined in [RFC 3811] and the IANA-GMPLS-TC-
MIB module.
2. Terminology
This document uses terminology from the MPLS architecture document
[RFC 3031], from the GMPLS architecture document [RFC 3945], and from
the MPLS Traffic Engineering MIB [RFC 3812]. Some frequently used
terms are described next.
An explicitly routed LSP (ERLSP) is referred to as a GMPLS tunnel.
It consists of in-segment(s) and/or out-segment(s) at the
egress/ingress LSRs, each segment being associated with one GMPLS-
enabled interface. These are also referred to as tunnel segments.
Additionally, at an intermediate LSR, we model a connection as
consisting of one or more in-segments and/or one or more out-
segments. The binding or interconnection between in-segments and
out-segments is performed using a cross-connect.
Nadeau & Farrel Standards Track PAGE 3
RFC 4802 GMPLS TE MIB February 2007
These segment and cross-connect objects are defined in the MPLS Label
Switching Router MIB (MPLS-LSR-STD-MIB) [RFC 3813], but see also the
GMPLS Label Switching Router MIB (GMPLS-LSR-STD-MIB) [RFC 4803] for
the GMPLS-specific extensions to these objects.
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 [RFC 3410].
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 [RFC 2578], STD 58, RFC 2579 [RFC 2579] and STD 58, RFC 2580
[RFC 2580].
4. Outline
Support for GMPLS traffic-engineered tunnels requires the following
configuration.
- Setting up tunnels with appropriate MPLS configuration parameters
using [RFC 3812].
- Extending the tunnel definitions with GMPLS configuration
parameters.
- Configuring loose and strict source routed tunnel hops.
These actions may need to be accompanied with corresponding actions
using [RFC 3813] and [RFC 4803] to establish and configure tunnel
segments, if this is done manually. Also, the in-segment and out-
segment performance tables, mplsInSegmentPerfTable and
mplsOutSegmentPerfTable [RFC 3813], should be used to determine
performance of the tunnels and tunnel segments, although it should be
noted that those tables may not be appropriate for measuring
performance on some types of GMPLS links.
4.1. Summary of GMPLS Traffic Engineering MIB Module
The following tables contain MIB objects for performing the actions
listed above when they cannot be performed solely using MIB objects
defined in MPLS-TE-STD-MIB [RFC 3812].
Nadeau & Farrel Standards Track PAGE 4
RFC 4802 GMPLS TE MIB February 2007
- Tunnel table (gmplsTunnelTable) for providing GMPLS-specific
tunnel configuration parameters.
- Tunnel hop, actual tunnel hop, and computed tunnel hop tables
(gmplsTunnelHopTable, gmplsTunnelARHopTable, and
gmplsTunnelCHopTable) for providing additional configuration of
strict and loose source routed tunnel hops.
- Performance and error reporting tables
(gmplsTunnelReversePerfTable and gmplsTunnelErrorTable).
These tables are described in the subsequent sections.
Additionally, the GMPLS-TE-STD-MIB module contains a new
notification.
- The GMPLS Tunnel Down Notification (gmplsTunnelDown) should be
used for all GMPLS tunnels in place of the mplsTunnelDown
notification defined in [RFC 3812]. An implementation must not
issue both the gmplsTunnelDown and the mplsTunnelDown
notifications for the same event. As well as indicating that a
tunnel has transitioned to operational down state, this new
notification indicates the cause of the failure.
5. Brief Description of GMPLS TE MIB Objects
The objects described in this section support the functionality
described in [RFC 3473] and [RFC 3472] for GMPLS tunnels. The tables
support both manually configured and signaled tunnels.
5.1. gmplsTunnelTable
The gmplsTunnelTable extends the MPLS traffic engineering MIB module
(MPLS-TE-STD-MIB [RFC 3812]) to allow GMPLS tunnels to be created
between an LSR and a remote endpoint, and existing GMPLS tunnels to
be reconfigured or removed.
Note that we only support point-to-point tunnel segments, although
multipoint-to-point and point-to-multipoint connections are supported
by an LSR acting as a cross-connect.
Each tunnel can thus have one out-segment originating at an LSR
and/or one in-segment terminating at that LSR.
Three objects within this table utilize enumerations in order to map
to enumerations that are used in GMPLS signaling. In order to
protect the GMPLS-TE-STD-MIB module from changes (in particular,
extensions) to the range of enumerations supported by the signaling
Nadeau & Farrel Standards Track PAGE 5
RFC 4802 GMPLS TE MIB February 2007
protocols, these MIB objects use textual conventions with values
maintained by IANA. For further details, see the IANA Considerations
section of this document.
5.2. gmplsTunnelHopTable
The gmplsTunnelHopTable is used to indicate additional parameters for
the hops, strict or loose, of a GMPLS tunnel defined in the
gmplsTunnelTable, when it is established using signaling. Multiple
tunnels may share hops by pointing to the same entry in this table.
5.3. gmplsTunnelARHopTable
The gmplsTunnelARHopTable is used to indicate the actual hops
traversed by a tunnel as reported by the signaling protocol after the
tunnel is set up. The support of this table is optional since not
all GMPLS signaling protocols support this feature.
5.4. gmplsTunnelCHopTable
The gmplsTunnelCHopTable lists the actual hops computed by a
constraint-based routing algorithm based on the gmplsTunnelHopTable.
The support of this table is optional since not all implementations
support computation of hop lists using a constraint-based routing
protocol.
5.5. gmplsTunnelErrorTable
The gmplsTunnelErrorTable provides access to information about the
last error that occurred on each tunnel known about by the MIB. It
indicates the nature of the error and when and how it was reported,
and it can give recovery advice through an admin string.
5.6. gmplsTunnelReversePerfTable
The gmplsTunnelReversePerfTable provides additional counters to
measure the performance of bidirectional GMPLS tunnels in which
packets are visible. It supplements the counters in
mplsTunnelPerfTable and augments gmplsTunnelTable.
Note that not all counters may be appropriate or available for some
types of tunnel.
Nadeau & Farrel Standards Track PAGE 6
RFC 4802 GMPLS TE MIB February 2007
5.7. Use of 32-bit and 64-bit Counters
64-bit counters are provided in the GMPLS-TE-STD-MIB module for
high-speed interfaces where the use of 32-bit counters might be
impractical. The requirements on the use of 32-bit and 64-bit
counters (copied verbatim from [RFC 2863]) are as follows:
For interfaces that operate at 20,000,000 (20 million) bits per
second or less, 32-bit byte and packet counters MUST be supported.
For interfaces that operate faster than 20,000,000 bits/second,
and slower than 650,000,000 bits/second, 32-bit packet counters
MUST be supported and 64-bit octet counters MUST be supported.
For interfaces that operate at 650,000,000 bits/second or faster,
64-bit packet counters AND 64-bit octet counters MUST be
supported.
6. Cross-referencing to the gmplsLabelTable
The gmplsLabelTable is found in the GMPLS-LABEL-STD-MIB module in
[RFC 4803] and provides a way to model labels in a GMPLS system where
labels might not be simple 32-bit integers.
The hop tables in this document (gmplsTunnelHopTable,
gmplsTunnelCHopTable, and gmplsTunnelARHopTable) and the segment
tables in [RFC 3813] (mplsInSegmentTable and mplsOutSegmentTable)
contain objects with syntax MplsLabel.
MplsLabel (defined in [RFC 3811]) is a 32-bit integer that is capable
of representing any MPLS Label and most GMPLS Labels. However, some
GMPLS Labels are larger than 32 bits and may be of arbitrary length.
Furthermore, some labels that may be safely encoded in 32 bits are
constructed from multiple sub-fields. Additionally, some GMPLS
technologies support the concatenation of individual labels to
represent a data flow carried as multiple sub-flows.
These GMPLS cases require that something other than a simple 32-bit
integer be made available to represent the labels. This is achieved
through the gmplsLabelTable contained in the GMPLS-LABEL-STD-MIB
[RFC 4803].
The tables in this document and [RFC 3813] that include objects with
syntax MplsLabel also include companion objects that are row
pointers. If the row pointer is set to zeroDotZero (0.0), then an
object of syntax MplsLabel contains the label encoded as a 32-bit
integer. But otherwise the row pointer indicates a row in another
MIB table that includes the label. In these cases, the row pointer
may indicate a row in the gmplsLabelTable.
Nadeau & Farrel Standards Track PAGE 7
RFC 4802 GMPLS TE MIB February 2007
This provides both a good way to support legacy systems that
implement MPLS-TE-STD-MIB [RFC 3812], and a significant simplification
in GMPLS systems that are limited to a single, simple label type.
Note that gmplsLabelTable supports concatenated labels through the
use of a label sub-index (gmplsLabelSubindex).
7. Example of GMPLS Tunnel Setup
This section contains an example of which MIB objects should be
modified to create a GMPLS tunnel. This example shows a best effort,
loosely routed, bidirectional traffic engineered tunnel, which spans
two hops of a simple network, uses Generalized Label requests with
Lambda encoding, has label recording and shared link layer
protection. Note that these objects should be created on the "head-
end" LSR.
First in the mplsTunnelTable:
{
mplsTunnelIndex = 1,
mplsTunnelInstance = 1,
mplsTunnelIngressLSRId = 192.0.2.1,
mplsTunnelEgressLSRId = 192.0.2.2,
mplsTunnelName = "My first tunnel",
mplsTunnelDescr = "Here to there and back again",
mplsTunnelIsIf = true(1),
mplsTunnelXCPointer = mplsXCIndex.3.0.0.12,
mplsTunnelSignallingProto = none(1),
mplsTunnelSetupPrio = 0,
mplsTunnelHoldingPrio = 0,
mplsTunnelSessionAttributes = recordRoute(4),
mplsTunnelOwner = snmp(2),
mplsTunnelLocalProtectInUse = false(2),
mplsTunnelResourcePointer = mplsTunnelResourceIndex.6,
mplsTunnelInstancePriority = 1,
mplsTunnelHopTableIndex = 1,
mplsTunnelPrimaryInstance = 0,
mplsTunnelIncludeAnyAffinity = 0,
mplsTunnelIncludeAllAffinity = 0,
mplsTunnelExcludeAnyAffinity = 0,
mplsTunnelPathInUse = 1,
mplsTunnelRole = head(1),
mplsTunnelRowStatus = createAndWait(5),
}
Nadeau & Farrel Standards Track PAGE 8
RFC 4802 GMPLS TE MIB February 2007
In gmplsTunnelTable(1,1,192.0.2.1,192.0.2.2):
{
gmplsTunnelUnnumIf = true(1),
gmplsTunnelAttributes = labelRecordingRequired(1),
gmplsTunnelLSPEncoding = tunnelLspLambda,
gmplsTunnelSwitchingType = lsc,
gmplsTunnelLinkProtection = shared(2),
gmplsTunnelGPid = lambda,
gmplsTunnelSecondary = false(2),
gmplsTunnelDirection = bidirectional(1)
gmplsTunnelPathComp = explicit(2),
gmplsTunnelSendPathNotifyRecipientType = ipv4(1),
gmplsTunnelSendPathNotifyRecipient = 'C0000201'H,
gmplsTunnelAdminStatusFlags = 0,
gmplsTunnelExtraParamsPtr = 0.0
}
Entries in the mplsTunnelResourceTable, mplsTunnelHopTable, and
gmplsTunnelHopTable are created and activated at this time.
In mplsTunnelResourceTable:
{
mplsTunnelResourceIndex = 6,
mplsTunnelResourceMaxRate = 0,
mplsTunnelResourceMeanRate = 0,
mplsTunnelResourceMaxBurstSize = 0,
mplsTunnelResourceRowStatus = createAndGo(4)
}
The next two instances of mplsTunnelHopEntry are used to denote the
hops this tunnel will take across the network.
The following denotes the beginning of the network, or the first hop
in our example. We have used the fictitious LSR identified by
"192.0.2.1" as our head-end router.
In mplsTunnelHopTable:
{
mplsTunnelHopListIndex = 1,
mplsTunnelPathOptionIndex = 1,
mplsTunnelHopIndex = 1,
mplsTunnelHopAddrType = ipv4(1),
mplsTunnelHopIpv4Addr = 192.0.2.1,
mplsTunnelHopIpv4PrefixLen = 9,
mplsTunnelHopType = strict(1),
mplsTunnelHopRowStatus = createAndWait(5),
}
Nadeau & Farrel Standards Track PAGE 9
RFC 4802 GMPLS TE MIB February 2007
The following denotes the end of the network, or the last hop in our
example. We have used the fictitious LSR identified by "192.0.2.2"
as our tail-end router.
In mplsTunnelHopTable:
{
mplsTunnelHopListIndex = 1,
mplsTunnelPathOptionIndex = 1,
mplsTunnelHopIndex = 2,
mplsTunnelHopAddrType = ipv4(1),
mplsTunnelHopIpv4Addr = 192.0.2.2,
mplsTunnelHopIpv4PrefixLen = 9,
mplsTunnelHopType = loose(2),
mplsTunnelHopRowStatus = createAndGo(4)
}
Now an associated entry in the gmplsTunnelHopTable is created to
provide additional GMPLS hop configuration indicating that the first
hop is an unnumbered link using Explicit Forward and Reverse Labels.
An entry in the gmplsLabelTable is created first to include the
Explicit Label.
In gmplsLabelTable:
{
gmplsLabelInterface = 2,
gmplsLabelIndex = 1,
gmplsLabelSubindex = 0,
gmplsLabelType = gmplsFreeformLabel(3),
gmplsLabelFreeform = 0xFEDCBA9876543210
gmplsLabelRowStatus = createAndGo(4)
}
In gmplsTunnelHopTable(1,1,1):
{
gmplsTunnelHopLabelStatuses = forwardPresent(0)
+reversePresent(1),
gmplsTunnelHopExplicitForwardLabelPtr = gmplsLabelTable(2,1,0)
gmplsTunnelHopExplicitReverseLabelPtr = gmplsLabelTable(2,1,0)
}
The first hop is now activated:
In mplsTunnelHopTable(1,1,1):
{
mplsTunnelHopRowStatus = active(1)
}
Nadeau & Farrel Standards Track PAGE 10
RFC 4802 GMPLS TE MIB February 2007
No gmplsTunnelHopEntry is created for the second hop as it contains
no special GMPLS features.
Finally, the mplsTunnelEntry is activated:
In mplsTunnelTable(1,1,192.0.2.1,192.0.2.2)
{
mplsTunnelRowStatus = active(1)
}

Note that an implementation MUST only issue one of
mplsTunnelDown and gmplsTunnelDown for any single event on a
single tunnel. If the tunnel has an entry in the

occur more rapidly, the implementation may simply fail to emit
some notifications during that period, or may queue them until

9. Security Considerations
It is clear that the MIB modules described in this document in
association with MPLS-TE-STD-MIB [RFC 3812] are potentially useful for
monitoring of MPLS and GMPLS tunnels. These MIB modules 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 these MIB modules
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:
Nadeau & Farrel Standards Track PAGE 47
RFC 4802 GMPLS TE MIB February 2007
o the gmplsTunnelTable and gmplsTunnelHopTable collectively contain
objects to provision GMPLS tunnels interfaces at their ingress
LSRs. Unauthorized write access to objects in these tables could
result in disruption of traffic on the network. This is
especially true if a tunnel has already been established.
Some of the readable objects in these MIB modules (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 gmplsTunnelTable, gmplsTunnelHopTable, gmplsTunnelARHopTable,
gmplsTunnelCHopTable, gmplsTunnelReversePerfTable, and
gmplsTunnelErrorTable collectively show the tunnel network
topology and status. If an administrator does not want to reveal
this information, then these tables should be considered
sensitive/vulnerable.
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 these MIB modules.
It is RECOMMENDED that implementers consider the security features as
provided by the SNMPv3 framework (see [RFC 3410], 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.

IANA has made the following assignments in the "NETWORK MANAGEMENT
PARAMETERS" registry located at http://www.iana.org/assignments/
smi-numbers in table:
...mib-2.transmission.mplsStdMIB (1.3.6.1.2.1.10.166)
Decimal Name References

13 GMPLS-TE-STD-MIB [RFC 4802]
In the future, GMPLS-related standards-track MIB modules should be
rooted under the mplsStdMIB (sic) subtree. IANA has been requested
to manage that namespace in the SMI Numbers registry [RFC 3811]. New
assignments can only be made via a Standards Action as specified in
[RFC 2434].
11.2. Dependence on IANA MIB Modules
Three MIB objects in the GMPLS-TE-STD-MIB module defined in this
document (gmplsTunnelLSPEncoding, gmplsTunnelSwitchingType, and
gmplsTunnelGPid) use textual conventions imported from the IANA-
GMPLS-TC-MIB module. The purpose of defining these textual
conventions in a separate MIB module is to allow additional values to
be defined without having to issue a new version of this document.
The Internet Assigned Numbers Authority (IANA) is responsible for the
assignment of all Internet numbers; it will administer the values
associated with these textual conventions.

11.2.1. IANA-GMPLS-TC-MIB Definition
This section provides the base definition of the IANA GMPLS TC MIB
module. This MIB module is under the direct control of IANA. Please
see the most updated version of this MIB at
<http://www.iana.org/assignments/ianagmplstc-mib>.
This MIB makes reference to the following documents: [RFC 2578],
[RFC 2579], [RFC 3471], [RFC 3473], [RFC 4202], [RFC 4328], and [RFC 4783].
IANA assigned an OID to the IANA-GMPLS-TC-MIB module specified in
this document as { mib-2 152 }.

DESCRIPTION
"This type is used to represent and control
the LSP encoding type of an LSP signaled by a GMPLS
signaling protocol.
This textual convention is strongly tied to the LSP
Encoding Types sub-registry of the GMPLS Signaling
Parameters registry managed by IANA. Values should be
assigned by IANA in step with the LSP Encoding Types
sub-registry and using the same registry management rules.
However, the actual values used in this textual convention
are solely within the purview of IANA and do not
necessarily match the values in the LSP Encoding Types
sub-registry.
The definition of this textual convention with the
addition of newly assigned values is published
periodically by the IANA, in either the Assigned
Numbers RFC, or some derivative of it specific to
Internet Network Management number assignments. (The
latest arrangements can be obtained by contacting the
IANA.)
Requests for new values should be made to IANA via
email (iana@iana.org)."
