"Copyright (C) The Internet Society (year). The
initial version of this MIB module was published
in RFC 3815. For full legal notices see the RFC
itself or see:

This MIB contains managed object definitions for
configuring and monitoring the Multiprotocol Label
Switching (MPLS), Label Distribution Protocol (LDP),
utilizing Frame Relay as the Layer 2 media."

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.'
