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 a
Generalized Multi-Protocol Label Switching (GMPLS) [GMPLSArch] based
traffic engineering. The tables and objects defined in this document
extend those defined in the equivalent document for MPLS traffic
engineering [TEMIB], and management of GMPLS traffic engineering is
built on management of MPLS traffic engineering.
This MIB module should be used in conjunction with the companion
document [GMPLSLSRMIB] for GMPLS based traffic engineering
configuration and management.
Comments should be made direct to the CCAMP mailing list at
ccamp@ops.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].

1.1. Migration Strategy
This MIB extends the traffic engineering MIB defined for use with
MPLS [TEMIB]. It provides additions for support of GMPLS tunnels.
The companion document modeling and managing GMPLS based LSRs
[GMPLSLSRMIB] extends MPLS LSR MIB [LSRMIB] with the same intentions.
Textual conventions and OBJECT-IDENTIFIERS are defined in [TCMIB] and
[GMPLSTCMIB].
2. Terminology
This document uses terminology from the MPLS architecture document
[RFC3031], from the GMPLS architecture document [GMPLSArch], and from
the MPLS Label Switch Router MIB [LSRMIB]. 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 in performed using a cross-connect.
These segment and cross-connect objects are defined in the MPLS Label
Switch Router MIB [LSRMIB], but see also the GMPLS Label Switch
Router MIB [GMPLSLSRMIB] for the GMPLS-specific extensions to these
objects.
3. 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].

4. Outline
Support for GMPLS traffic-engineered tunnels requires the following
configuration.
- Setting up tunnels with appropriate MPLS configuration parameters
using [TEMIB].
- Extending the tunnels with GMPLS configuration parameters.
- Configuring tunnel loose and strict source routed hops.
These actions may need to be accompanied with corresponding actions
using [LSRMIB] and [GMPLSLSRMIB] to establish and configure tunnel
segments, if this is done manually. Also, the in-segment and out-
segment performance tables, mplsInSegmentPerfTable and
mplsOutSegmentPerfTable [LSRMIB], 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 times of GMPLS links.
4.1. Summary of GMPLS Traffic Engineering MIB Module
The MIB objects for performing the actions listed above that cannot
be performed solely using the MIB objects defined in [TEMIB] consist
of the following tables.
- Tunnel Table (gmplsTunnelTable) for providing GMPLS-specific
tunnel configuration parameters.
- Tunnel specified, actual, and computed hop tables
(gmplsTunnelHopTable, gmplsTunnelARHopTable, and
gmplsTunnelCHopTable) for providing additional configuration of
strict and loose source routed tunnel hops.
- Performance and error reporting tables (gmplsTunnelPerfTable and
gmplsTunnelErrorTable).
These tables are described in the subsequent sections.
5. Brief Description of GMPLS TE MIB Objects
The objects described in this section support the functionality
described in [GMPLSRSVPTE] and [GMPLSCRLDP] for GMPLS tunnels.
The tables support both manually configured and signaled tunnels.
5.1. gmplsTunnelTable
The gmplsTunnelTable extends the MPLS traffic engineering MIB 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
multi-point-to-point and point-to-multi-point 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.
Nadeau, Srinivasan, Farrel, Hall and Harrison [Page 4]
Internet Draft draft-ietf-ccamp-gmpls-te-mib-01.txt August 2003
5.2. gmplsTunnelHopTable
The gmplsTunnelHopTable is used to indicate additional parameters for
the hops, strict or loose, of a GMPLS tunnel defined in
gmplsTunnelTable, when it is established using signaling. Multiple
tunnels may share the same 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 setup. 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 list 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, when and how it was reported and
can give recovery advice through a display string.
5.6. gmplsTunnelPerfTable
gmplsTunnelPerfTable provides additional counters to measure the
performance of 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.
6. Cross-referencing to the mplsLabelTable
The gmplsLabelTable is found in a MIB module in [GMPLSLSRMIB] 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 (gmplsHopTable, gmplsCHopTable and
gmplsARHopTable) use arbitrary indexes to point to entries in the
mplsLabelTable to indicate specific label values.
Since the primary indexes into gmplsLabelTable are the interface
index and a simple 32 bit integer (gmplsLabelIndex), in systems where
the nature of a label is well-known, and where the label can safely
be encoded as a 32 bit integer (for example a conventional MPLS
system), the gmplsLabelTable does not need to be supported in the
code implementation and the index pointers to the gmplsLabelTable
Nadeau, Srinivasan, Farrel, Hall and Harrison [Page 5]
Internet Draft draft-ietf-ccamp-gmpls-te-mib-01.txt August 2003
(gmplsTunnelHopExplicitLabel, gmplsTunnelHopExplicitReverseLabel,
gmplsTunnelCHopExplicitLabel, gmplsTunnelCHopExplicitReverseLabel,
gmplsTunnelARHopExplicitLabel, gmplsTunnelARHopExplicitReverseLabel)
may be replaced with the direct label values.
This provides both a good way to support legacy systems that
implement the previous version of this MIB [TEMIB], 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 = 123.123.125.1,
mplsTunnelEgressLSRId = 123.123.126.1,
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 (0),
mplsTunnelResourcePointer = mplsTunnelResourceIndex.6,
mplsTunnelInstancePriority = 1,
mplsTunnelHopTableIndex = 1,
mplsTunnelPrimaryInstance = 0,
mplsTunnelIncludeAnyAffinity = 0,
mplsTunnelIncludeAllAffinity = 0,
mplsTunnelExcludeAnyAffinity = 0,
mplsTunnelPathInUse = 1,
mplsTunnelRole = head(1),
mplsTunnelRowStatus = createAndWait (5),
}
Nadeau, Srinivasan, Farrel, Hall and Harrison [Page 6]
Internet Draft draft-ietf-ccamp-gmpls-te-mib-01.txt August 2003
In gmplsTunnelTable(1,1,123.123.125.1,123.123.126.1):
{
gmplsTunnelIsUnnum = true (1),
gmplsTunnelAttributes = labelRecordingRequired (1),
gmplsTunnelLSPEncoding = tunnelLspLambda (8),
gmplsTunnelSwitchingType = lsc (150),
gmplsTunnelLinkProtection = shared (2),
gmplsTunnelGPid = lambda (37),
gmplsTunnelDirection = bidirectional (1)
}
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.
We have used the fictitious LSR identified by "123.123.125.1" as our
example head-end router.
In mplsTunnelHopTable:
{
mplsTunnelHopListIndex = 1,
mplsTunnelPathOptionIndex = 1,
mplsTunnelHopIndex = 1,
mplsTunnelHopAddrType = ipV4 (1),
mplsTunnelHopIpv4Addr = 123.123.125.1,
mplsTunnelHopIpv4PrefixLen = 9,
mplsTunnelHopType = strict (1),
mplsTunnelHopRowStatus = createAndGo (4),
}
The following denotes the end of the network, or the last hop in our
example. We have used the fictitious LSR identified by
"123.123.126.1" as our end router.
In mplsTunnelHopTable:
{
mplsTunnelHopListIndex = 1,
mplsTunnelPathOptionIndex = 1,
mplsTunnelHopIndex = 2,
mplsTunnelHopAddrType = ipV4 (1),
mplsTunnelHopIpv4Addr = 123.123.126.1,
mplsTunnelHopIpv4PrefixLen = 9,
mplsTunnelHopType = loose (2),
}
Nadeau, Srinivasan, Farrel, Hall and Harrison [Page 7]
Internet Draft draft-ietf-ccamp-gmpls-te-mib-01.txt August 2003
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.
In gmplsTunnelHopTable(1,1,1):
{
gmplsTunnelHopUnnumAddrType = unnumberedIpV4(2),
gmplsTunnelHopLabelStatuses = forwardPresent(0)
+reversePresent(1),
gmplsTunnelHopExplicitLabel = mplsLabelIndex.2756132,
gmplsTunnelHopExplicitReverseLabel = mplsLabelIndex.65236213
}
No gmplsTunnelHopEntry is created for the second hop as it contains
no special GMPLS features.
Finally the mplsTunnelEntry is activated:
In mplsTunnelTable(1,1,123.123.125.1,123.123.126.1)
{
mplsTunnelRowStatus = active(1)
}

9. Security Considerations
It is clear that the MIB modules described in this document in
association with the MPLS-TE-STD-MIB 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:
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. The use of stronger
mechanisms such as SNMPv3 security should be considered where
possible. Specifically, SNMPv3 VACM and USM MUST be used with any
SNMPv3 agent which implements these MIB modules.
Nadeau, Srinivasan, Farrel, Hall and Harrison [Page 36]
Internet Draft draft-ietf-ccamp-gmpls-te-mib-01.txt August 2003
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,
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 [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.

15. Changes and Pending Work
This section to be removed before the draft progresses to RFC.
15.1. Pending Work
The following work items have been identified for this draft. They
will be addressed in a future version.
- Clarify which objects can be modified when rowStatus and
adminStatus are set to active
- Sort out conformance statement which is a mess
- Expand conformance statements to give one for monitoring only,
and one for monitoring and control.
- Bring references up to date, include all drafts referenced from
this document, and exclude those that are not referenced.
- Consider a way to expose tunnel head, tunnel tail, and tunnel
transit entries through distinct indexing or tables.
- Provide support for configuring tunnel resources in GMPLS
systems. For example, SONET/SDH or G.709. This might be done
through an arbitrary RowPointer to an external MIB.
- Link Ids in EROs and RROs for use of bundled links.
- Crankback request and reported information.
- Control and reporting of upstream and downstream Notify
Recipients.
- Add support for control and reporting of GMPLS Administrative
Status object.
- Add support for IF_ID control and error reporting.
- Add support for selection and configuration of restart options.
- Update enumerated types in line with latest GMPLS drafts. Examine
how these can be managed by IANA.
Nadeau, Srinivasan, Farrel, Hall and Harrison [Page 41]
Internet Draft draft-ietf-ccamp-gmpls-te-mib-01.txt August 2003
- Resolve ownership of enumerated types that are also defined in
GMPLS or routing drafts. These could be owned by IANA, imported
from another MIB, or manually kept in step here. If they are not
maintained externally then they are likely to diverge and MIB
implementations will need to provide mappings.
- Update examples.
- Update MIB description in section 5.
- Update in-line references.
Nadeau, Srinivasan, Farrel, Hall and Harrison [Page 42]
