        "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.'
