RFC 3815
Definitions of Managed Objects for the Multiprotocol Label Switching (MPLS), Label Distribution Protocol (LDP)
4.1. The MPLS-LDP-ATM-STD-MIB Module
This MIB Module MUST be supported if LDP uses ATM as the Layer 2 medium. There are three tables in this MIB Module. Two tables are for configuring LDP to use ATM. These tables are the mplsLdpEntityAtmTable and the mplsLdpEntityAtmLRTable. The third table is the mplsLdpAtmSessionTable which is a read-only table. This MIB Module IMPORTS the AtmVpIdentifier TEXTUAL-CONVENTION from [RFC2514].
4.1.1. The LDP Entity ATM Table
The mplsLdpEntityAtmTable provides a way to configure information which would be contained in the "Optional Parameter" portion of an LDP PDU Initialization Message.4.1.2. The LDP Entity ATM Label Range Table
The mplsLdpEntityAtmLRTable provides a way to configure information which would be contained in the "ATM Label Range Components" portion of an LDP PDU Intialization Message, see [RFC3035] and [RFC3036].4.1.3. The LDP ATM Session Table
The MPLS LDP ATM Session Table is a read-only table which contains session information specific to ATM.

If the value of this object is 'unidirectional(1)',

This is the EXACT value for the ATM Session Parameter,
field D (for VC Directionality). The ATM Session
Parameter is an optional parameter in the
Initialization Message.
The description from rfc3036.txt is:
'D, VC Directionality
A value of 0 specifies bidirectional VC capability,
meaning the LSR can (within a given VPI) support
the use of a given VCI as a label for both link
directions independently. A value of 1
specifies unidirectional VC capability, meaning
(within a given VPI) a given VCI may appear in
a label mapping for one direction on the link
only. When either or both of the peers
specifies unidirectional VC capability, both
LSRs use unidirectional VC label assignment for
the link as follows. The LSRs compare their
LDP Identifiers as unsigned integers. The LSR
with the larger LDP Identifier may assign
only odd-numbered VCIs in the VPI/VCI
range as labels. The system with the smaller
LDP Identifier may assign only even-numbered
VCIs in the VPI/VCI range as labels.'

NOTE: The ranges for a specific LDP Entity
are UNIQUE and non-overlapping. For example,
for a specific LDP Entity index, there could
be one entry having LowerBound vpi/vci == 0/32, and
UpperBound vpi/vci == 0/100, and a second entry
for this same interface with LowerBound
vpi/vci == 0/101 and UpperBound vpi/vci == 0/200.
However, there could not be a third entry with
LowerBound vpi/vci == 0/200 and
UpperBound vpi/vci == 0/300 because this label
range overlaps with the second entry (i.e., both
entries now have 0/200).
A row will not become active unless a unique and
non-overlapping range is specified.
At least one label range entry for a
specific LDP Entity MUST
include the default VPI/VCI values denoted
in the LDP Entity Table.
A request to create a row with an overlapping
range should result in an inconsistentValue
error."

4.2. The MPLS-LDP-FRAME-RELAY-STD-MIB Module
This MIB Module MUST be supported if LDP uses FRAME RELAY as the
Layer 2 medium. There are three tables in this MIB Module. Two
tables are to configure LDP for using Frame Relay. These tables are
the mplsLdpEntityFrameRelayTable and the
mplsLdpEntityFrameRelayLRTable. The third table,
mplsLdpFrameRelaySessionTable, is a read-only table. This MIB Module
IMPORTS the DLCI TEXTUAL-CONVENTION from [RFC2115].
4.2.1. The LDP Entity Frame Relay Table
The mplsLdpEntityFrameRelayTable provides a way to configure
information which would be contained in the "Optional Parameter"
portion of an LDP PDU Initialization Message.
4.2.2. The LDP Entity Frame Relay Label Range Table
The mplsLdpEntityFrameRelayLRTable provides a way to configure
information which would be contained in the "Frame Relay Label Range
Components" portion of an LDP PDU Intialization Message, see
[RFC3034] and [RFC3036].
4.2.3. The LDP Frame Relay Session Table
The mplsLdpFrameRelaySessionTable is a table which contains session
information specific to Frame Relay.

DESCRIPTION
"This value represents either the InterfaceIndex of
the 'ifLayer' where the Frame Relay Labels 'owned' by this
entry were created, or 0 (zero). The value of zero
means that the InterfaceIndex is not known. For example,
if the InterfaceIndex is created subsequent to the
Frame Relay Label's creation, then it would not be known.
However, if the InterfaceIndex is known, then it must
be represented by this value.
If an InterfaceIndex becomes known, then the
network management entity (e.g., SNMP agent) responsible
for this object MUST change the value from 0 (zero) to the
value of the InterfaceIndex. If an Frame Relay Label is
being used in forwarding data, then the value of this
object MUST be the InterfaceIndex."

DESCRIPTION
"If the value of this object is 'bidirectional(0)', then
the LSR supports the use of a given DLCI as a label for
both directions independently. If the value of
this object is 'unidirectional(1)', then the LSR
uses the given DLCI as a label in only one direction.
This is the EXACT value for the Frame Relay Session
Parameter, field D (for VC Directionality). The
Frame Relay Session Parameter is an optional
parameter in the Initialization Message.
The description from rfc3036.txt is:
'D, VC Directionality
A value of 0 specifies bidirectional VC capability,
meaning the LSR can support the use of a given
DLCI as a label for both link directions
independently. A value of 1 specifies
unidirectional VC capability, meaning a given
DLCI may appear in a label mapping for one
direction on the link only. When either or both
of the peers specifies unidirectional VC
capability, both LSRs use unidirectional VC
label assignment for the link as follows. The
LSRs compare their LDP Identifiers as unsigned
integers. The LSR with the larger LDP
Identifier may assign only odd-numbered DLCIs
in the range as labels. The system with the
smaller LDP Identifier may assign only
even-numbered DLCIs in the range as labels.'
