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 Multiprotocol Label Switching (GMPLS) [RFC3945] Label
Switching Router (LSR).

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,
reference 2119
[RFC2119].

1.1. Migration Strategy

MPLS LSRs may be modeled and managed using the MPLS-LSR-STD-MIB
module [RFC3813].

LSRs may be migrated to be modeled and managed 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.

draft-ietf-ccamp-gmpls-lsr-mib-15.txt September 2006

The GMPLS LSR MIB module (GMPLS-LSR-STD-MIB) (GMPLS-LSR-STD-MIB), defined in this document
document, extends the MPLS-LSR-STD-MIB module [RFC3813] through a
series of 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-LSR-STD-MIB support to
GMPLS-LSR-STD-MIB support GMPLS-LSR-STD-
MIB support, an implementation needs only to add support for the
additional tables and objects defined in GMPLS-LSR-STD-MIB. The
gmplsInterfaceSignalingCaps object allows an implementation to use
the objects and tables of GMPLS-LSR-STD-MIB without supporting the
GMPLS protocols.

The GMPLS Label MIB module (GMPLS-LABEL-STD-MIB) (GMPLS-LABEL-STD-MIB), also defined in
this
document document, allows labels to be configured and examined, and it
supports more varieties of label labels as appropriate for GMPLS. Labels
may be referenced using a row pointer from objects within the
GMPLS-LSR-STD-MIB GMPLS-
LSR-STD-MIB module. MPLS implementations (MPLS-LSR-STD-MIB) may also
reference labels held in the GMPLS-LABEL-STD-MIB module through the
various label pointer objects in the MPLS-LSR-STD-MIB module (such as
mplsInSegmentLabelPtr), and may do so without implementing the
GMPLS-LSR-STD-MIB module.

The companion document modeling and managing GMPLS based GMPLS-based traffic
engineering [GMPLSTEMIB] [RFC4802] extends the MPLS-TE-STD-MIB module [RFC3812]
with the same intentions.

Textual conventions are defined in [GMPLSTCMIB] [RFC4801], which extends the set
of textual conventions originally defined in [RFC3811].

2. Terminology

This document uses terminology from the document describing the MPLS
architecture [RFC3031] and the GMPLS architecture [RFC3945].

A label switched path Label Switched Path (LSP) is modeled as a connection consisting of
one or more incoming segments (in-segments) and/or one or more
outgoing segments (out-segments) at an LSR. The association or
interconnection of the in-segments and out-segments is accomplished
by using a cross-connect. We use the terminology "connection" and
"LSP" interchangeably where the meaning is clear from the context.

in-segment This is analogous to a GMPLS label Label on an interface.

out-segment This is analogous to a GMPLS label Label on an interface.

cross-connect This describes the conceptual connection between a set
of in-segments and out-segments. Note that either set
may be empty; for example, a cross-connect may connect
only out-segments together with no in-segments in the
case where an LSP originates on an LSR.

draft-ietf-ccamp-gmpls-lsr-mib-15.txt September 2006

The terms 'ingress' and 'head-end' (or 'head') are used in this
document to indicate the signaling source of an LSP. This is
sometimes also referred to as the 'sender'.

The terms 'egress' and 'tail-end' (or 'tail') are used in this
document to indicate the signaling destination of an LSP.

The term 'upstream' is used in this document to refer to the part of
an LSP that is closer to the ingress than the current point of
reference.

The term 'downstream' is used in this document to refer to the part
of an LSP that is closer to the egress than the current point of
reference.

The term 'forward' is used in this document to indicate the direction
of data flow from the ingress toward the egress.

The term 'reverse' is used in this document to indicate the direction
of data flow from the egress toward the ingress.

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. Outline

4.1

4.1. MIB Modules

There are two MIB modules defined in this document.

The GMPLS-LSR-STD-MIB module contains tables that sparse augment
tables defined in the MPLS-LSR-STD-MIB module [RFC3813]. This MIB
module is used in conjunction with the MPLS-LSR-STD-MIB module
[RFC3813] in systems that support GMPLS.

The GMPLS-LABEL-STD-MIB module contains objects for managing GMPLS
labels
Labels when they cannot be represented using the textual conventions
of the MPLS-TC-STD-MIB module [RFC3811], or when more detailed access
to the sub-fields of the labels is required.

draft-ietf-ccamp-gmpls-lsr-mib-15.txt September 2006

4.1.1

4.1.1. Summary of the GMPLS-LSR-STD-MIB Module

The MIB tables in the GMPLS-LSR-STD-MIB module are as follows. follows:

- The interface configuration table (gmplsInterfaceTable), which (gmplsInterfaceTable) sparse
augments the mplsInterfaceTable [RFC3813] to enable the GMPLS
protocol on MPLS-capable interfaces.

- The in-segment (gmplsInSegmentTable) and out-segment
(gmplsOutSegmentTable) tables sparse augment mplsInSegmentTable
and mplsOutSegmentTable [RFC3813] to enable configuration of
GMPLS-specific parameters for LSP segments at an LSR.

These tables are described in the subsequent sections.

4.1.2

4.1.2. Summary of the GMPLS-LABEL-STD-MIB Module

There is one MIB table in the GMPLS-LABEL-STD-MIB module as follows. follows:

- The gmplsLabelTable allows Generalized Labels to be defined and
managed in a central location. Generalized Labels can be of
variable length and have distinct bit-by-bit interpretations
depending upon how they are defined for the specific technology in
which they are used. For example, labels used for MPLS packet
switching are different in length and content from labels used in TDM
Time Division Multiplexer (TDM) timeslot switching.

4.2. Configuring Statically Provisioned LSPs

Configuring statically provisioned GMPLS LSPs through an LSR involves
the following steps:

- Configuring an interface using the MPLS-LSR-STD-MIB module
[RFC3813].

- Enabling GMPLS on GMPLS capable GMPLS-capable interfaces using the
GMPLS-LSR-STD-MIB GMPLS-LSR-
STD-MIB module in this document.

- Configuring in in-segments and out-segments using the MPLS-LSR-STD-MIB MPLS-LSR-STD-
MIB module [RFC3813].

- Configuring GMPLS extensions to the in-segments and out-segments
using the GMPLS-LSR-STD-MIB module in this document.

- Setting up the cross-connect table in the MPLS-LSR-STD-MIB module
[RFC3813] to associate segments and/or to indicate connection
origination and termination.

draft-ietf-ccamp-gmpls-lsr-mib-15.txt September 2006

- Optionally setting up labels in the label table in the
GMPLS-LABEL-STD-MIB GMPLS-
LABEL-STD-MIB module in this document if the textual convention
MplsLabel [RFC3811] is not capable of holding the required label
(for example, if the label requires more than 32 bits to encode
it), or if the operator wishes to disambiguate GMPLS
label Label types.

- Optionally specifying label stack actions in the MPLS-LSR-STD-MIB
module [RFC3813].

- Optionally specifying segment traffic parameters in the
MPLS-LSR-STD-MIB MPLS-LSR-
STD-MIB module [RFC3813].

5. Bidirectional LSPs

The GMPLS-LSR-STD-MIB module supports bidirectional LSPs as required
for GMPLS. A single value of mplsXCIndex is shared by all of the
segments for the entire bidirectional LSP. This facilitates a simple
reference from [RFC3812] and [GMPLSTEMIB], [RFC4802] and makes fate-sharing more
obvious.

It is, however, important that the direction of segments is
understood to avoid connecting all in-segments to all out-segments.
This is achieved by an object in each segment that indicates the
direction of the segment with respect to data flow.

A segment that is marked as 'forward' carries data from the 'head' of
the LSP to the 'tail'. A segment marked as 'reverse' carries data in
the reverse direction.

Where an LSP is signaled using a conventional signaling protocol, the
'head' of the LSP is the source of the signaling (also known as the
ingress) and the 'tail' is the destination (also known as the
egress). For manually configured LSPs LSPs, an arbitrary decision must be
made about which segments are 'forward' and which 'reverse'. For
consistency
consistency, this decision should be made across all LSRs that
participate in the LSP by assigning 'head' and 'tail' ends to the
LSP.

6. Example of LSP Setup

In this section section, we provide a brief example of using the MIB objects
described in sections 7 and 8 to set up an LSP. While this example
is not meant to illustrate every nuance of the MIB modules, it is
intended as an aid to understanding some of the key concepts. It is
meant to be read after going through the MIB modules themselves. A
prerequisite is an understanding of the MPLS-LSR-STD-MIB module
[RFC3813].

Suppose that one would like to manually create a best-effort,
bi-directional
bidirectional LSP. Assume that, in the forward direction, the LSP
draft-ietf-ccamp-gmpls-lsr-mib-15.txt September 2006
enters the LSR via MPLS interface A with ifIndex 12 and exits the LSR
via MPLS interface B with ifIndex 13. For the reverse direction, we
assume that the LSP enters via interface B and leaves via interface A
(i.e.
(i.e., the forward and reverse directions use the same bi-directional bidirectional
interfaces). Let us also assume that we do not wish to have a label
stack beneath the top label on the outgoing labeled packets. The
following example illustrates which rows and corresponding objects
might be created to accomplish this.

We must first create rows in the gmplsLabelTable corresponding to the
labels required for each of the forward forward- and reverse direction reverse-direction in-
and out-segments. For the purpose of this example example, the forward and
reverse labels on each interface will be the same, hence we need to
create just two rows in the gmplsLabelTable - one for each interface.

In gmplsLabelTable:
{
gmplsLabelInterface = 12,
gmplsLabelIndex = 1,
gmplsLabelSubindex = 0,
gmplsLabelType = gmplsFreeformLabel(3),
gmplsLabelFreeform = 0x123456789ABCDEF0
gmplsLabelRowStatus = createAndGo(4)
}
In gmplsLabelTable:
{
gmplsLabelInterface = 13,
gmplsLabelIndex = 1,
gmplsLabelSubindex = 0,
gmplsLabelType = gmplsFreeformLabel(3),
gmplsLabelFreeform = 0xFEDCBA9876543210
gmplsLabelRowStatus = createAndGo(4)
}

We must next create the appropriate in-segment and out-segment
entries. These are done in [RFC3813] using the mplsInSegmentTable
and mplsOutSegmentTable. Note that we use a row pointer to the two
rows in the gmplsLabelTable rather than specifying specify the labels explicitly
in the in- and out-segment tables. Also note that the row status for
each row is set to createAndWait(5) to allow corresponding entries in
the gmplsInSegmentTable and gmplsOutSegmentTable to be created.

draft-ietf-ccamp-gmpls-lsr-mib-15.txt September 2006

For the forward direction.

In mplsInSegmentTable:
{
mplsInSegmentIndex = 0x00000015
mplsInSegmentLabel = 0, -- incoming label in label table
mplsInSegmentNPop = 1,
mplsInSegmentInterface = 12, -- incoming interface

-- RowPointer MUST point to the first accessible column.
mplsInSegmentTrafficParamPtr = 0.0,
mplsInSegmentLabelPtr = gmplsLabelTable (12, 1, 0) gmplsLabelTable(12,1,0)
mplsInSegmentRowStatus = createAndWait(5)
}

In mplsOutSegmentTable:
{
mplsOutSegmentIndex = 0x00000012,
mplsOutSegmentInterface = 13, -- outgoing interface
mplsOutSegmentPushTopLabel = true(1),
mplsOutSegmentTopLabel = 0, -- outgoing label in label table

-- RowPointer MUST point to the first accessible column.
mplsOutSegmentTrafficParamPtr = 0.0,
mplsOutSegmentLabelPtr = gmplsLabelTable (13, 1, 0) gmplsLabelTable(13,1,0)
mplsOutSegmentRowStatus = createAndWait(5)
}
For the reverse direction.

In mplsInSegmentTable:
{
mplsInSegmentIndex = 0x00000016
mplsInSegmentLabel = 0, -- incoming label in label table
mplsInSegmentNPop = 1,
mplsInSegmentInterface = 13, -- incoming interface

-- RowPointer MUST point to the first accessible column.
mplsInSegmentTrafficParamPtr = 0.0,
mplsInSegmentLabelPtr = gmplsLabelTable (13, 1, 0) gmplsLabelTable(13,1,0)

mplsInSegmentRowStatus = createAndWait(5)
}
draft-ietf-ccamp-gmpls-lsr-mib-15.txt September 2006

In mplsOutSegmentTable:
{
mplsOutSegmentIndex = 0x00000013,
mplsOutSegmentInterface = 12, -- outgoing interface
mplsOutSegmentPushTopLabel = true(1),
mplsOutSegmentTopLabel = 0, -- outgoing label in label table

-- RowPointer MUST point to the first accessible column.
mplsOutSegmentTrafficParamPtr = 0.0,
mplsOutSegmentLabelPtr = gmplsLabelTable (12, 1, 0) gmplsLabelTable(12,1,0)
mplsOutSegmentRowStatus = createAndWait(5)
}

These table entries are extended by entries in the
gmplsInSegmentTable and gmplsOutSegmentTable. Note that the nature
of the 'extends' relationship is a sparse augmentation so that the
entry in the gmplsInSegmentTable has the same index values as the
entry in the mplsInSegmentTable. Similarly, the entry in the
gmplsOutSegmentTable has the same index values as the entry in the
mplsOutSegmentTable.

First for the forward direction:

In gmplsInSegmentTable(0x00000015)
{
gmplsInSegmentDirection = forward (1) forward(1)
}

In gmplsOutSegmentTable(0x00000012)
{
gmplsOutSegmentDirection = forward (1) forward(1)
}
Next for the reverse direction:

In gmplsInSegmentTable(0x00000016)
{
gmplsInSegmentDirection = reverse (2) reverse(2)
}

In gmplsOutSegmentTable(0x00000013)
{
gmplsOutSegmentDirection = reverse (2) reverse(2)
}

Next, two cross-connect entries are created in the mplsXCTable of the
MPLS-LSR-STD-MIB [RFC3813], thereby associating the newly created
segments together.

draft-ietf-ccamp-gmpls-lsr-mib-15.txt September 2006

In mplsXCTable:
{
mplsXCIndex = 0x01,
mplsXCInSegmentIndex = 0x00000015,
mplsXCOutSegmentIndex = 0x00000012,
mplsXCLspId = 0x0102 -- unique ID
mplsXCLabelStackIndex = 0x00, -- only a single outgoing label
mplsXCRowStatus = createAndGo(4)
}

In mplsXCTable:
{
mplsXCIndex = 0x02,
mplsXCInSegmentIndex = 0x00000016,
mplsXCOutSegmentIndex = 0x00000013,
mplsXCLspId = 0x0102 -- unique ID
mplsXCLabelStackIndex = 0x00, -- only a single outgoing label
mplsXCRowStatus = createAndGo(4)
}

Finally, the in-segments and out-segments are activated.

In mplsInSegmentTable(0x00000015):
{
mplsInSegmentRowStatus = active(1)
}
In mplsInSegmentTable(0x00000016):
{
mplsInSegmentRowStatus = active(1)
}
In mplsOutSegmentTable(0x00000012):
{
mplsOutSegmentRowStatus = active(1)
}

In mplsOutSegmentTable(0x00000013):
{
mplsOutSegmentRowStatus = active(1)
}

STATUS current
DESCRIPTION
"Table of GMPLS Labels. This table allows the representation
of the more complex label forms required for GMPLS which that cannot
be held within the textual convention MplsLabel. That is TEXTUAL-CONVENTION MplsLabel; that is, labels
draft-ietf-ccamp-gmpls-lsr-mib-15.txt September 2006
that cannot be encoded within 32 bits. It is, nevertheless nevertheless, also
capable of holding 32 bit 32-bit labels or regular MPLS labels Labels if
desired.

Each entry in this table represents an individual GMPLS label Label
value. The representation of Labels in the tables in other MIB
modules may be referred achieved by a referrence to using an entry in this
table by means of a row pointer into this table. The indexing
of this table provides for arbitrary indexing and also for
concatenation of labels.

For an example of label concatenation concatenation, see RFC3945 RFC 3945, section 7.1.
In essence, a GMPLS label Label may be composite in order to identify
a set of resources in the data plane. Practical examples are
timeslots and wavelength sets (which are not contiguous like
wavebands).

The indexing mechanism allows multiple entries in this table to
be seen as a sequence of labels that should be concatenated.
Ordering is potentially very sensitive for concatenation."

gmplsLabelEntry OBJECT-TYPE
SYNTAX GmplsLabelEntry
MAX-ACCESS not-accessible
STATUS current
DESCRIPTION
"An entry in this table represents a single label value. There
are three indexes into the table.

- The interface index may be helpful to distinguish which
labels are in use on which interfaces or to handle cases
where there are a very large number of labels in use in the
system. When label representation is desired to apply to the
whole system or when it is not important to distinguish
labels by their interfaces, this index MAY be set to zero.

- The label index provides a way of identifying the label.

- The label sub-index is only used for concatenated labels. It
identifies each component label. When non-concatenated labels
are used, this index SHOULD be set to zero.

A storage type object is supplied to control the storage type
for each entry, but implementations should note that the storage
type of conceptual rows in other tables that include row
pointers to an entry in this table SHOULD dictate the storage
type of the rows in this table where the row in the other table
is more persistent."

9. Security Considerations

It is clear that the MIB modules described in this document in
association with the MPLS-LSR-STD-MIB [RFC3813] are potentially useful
for monitoring of GMPLS LSRs. 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 gmplsInterfaceTable, gmplsInSegmentTable, gmplsOutSegmentTable
gmplsOutSegmentTable, and gmplsLabelTable collectively contain
objects to provision GMPLS interfaces, LSPs LSPs, and their associated
parameters on a Label Switching Router (LSR). Unauthorized write
access to objects in these tables, tables could result in disruption of
traffic on the network. This is especially true if an LSP has
already been established.

draft-ietf-ccamp-gmpls-lsr-mib-15.txt September 2006

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 gmplsInterfaceTable, gmplsInSegmentTable, gmplsOutSegmentTable
gmplsOutSegmentTable, and gmplsLabelTable collectively show the
LSP network topology and its capabilities. If an Administrator 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.

This document extends the MIB tables in [RFC3813]. The authors would
like to express their gratitude to all those who worked on that
earlier MIB document.

The authors would like to express their thanks to Dan Joyle for his
careful review and comments on early versions of the Label Table. label table.
Special thanks to Joan Cucchiara and Len Nieman for their help with
compilation issues. Lars Eggert, Tom Petch, Dan Romascanu, and Bert
Wijnen provided useful input in the final stages of review.

Joan Cucchiara provided a helpful and very thorough MIB Doctor
review.

11. IANA Considerations

IANA is requested to root has rooted MIB objects in the two MIB modules contained in this
document under the mplsStdMIB subtree.

Upon approval of this document, the

IANA will make has made the following assignments in the "NETWORK MANAGEMENT
PARAMETERS" registry located at http://www.iana.org/assignments/smi-numbers http://www.iana.org/assignments/
smi-numbers in table:

...mib-2.transmission.mplsStdMIB (1.3.6.1.2.1.10.166)

Decimal Name References
------- ----- ----------
TBD+2 GMPLS-LSR-STD-MIB [RFC-ccamp-gmpls-lsr-mib]
TBD+3 GMPLS-LABEL-STD-MIB [RFC-ccamp-gmpls-lsr-mib]

-- RFC Editor. Please replace YYY in the main text with the OID assigned
-- by IANA for
15 GMPLS-LSR-STD-MIB and remove this note.

-- RFC Editor. Please replace ZZZ in the main text with the OID assigned
-- by IANA for [RFC4803]
16 GMPLS-LABEL-STD-MIB and remove this note. [RFC4803]

In the future, GMPLS related standards track 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 [RFC3811]. New
assignments can only be made via a Standards Action as specified in
[RFC2434].
