Object

column r/w Enumeration

If the value of this object is 'bidirectional(0)',
a given VCI, within a given VPI, is used as a
label for both directions independently.
              
If the value of this object is 'unidirectional(1)',
a given VCI within a VPI designates one direction.
              
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.'
