If this LSP terminates or is cross-connecting
on this LSR, then this RowPointer should point
to an instance of an object in the
mplsLsrInSegmentTable. In other words if
the value of jnxMplsLdpLspType is
terminatingLsp(2) or crossConnectingLsp(4),
then this should point to an instance of an object
in the LSR-MIB's mplsInSegmentTable.
Otherwise, a value of zeroDotzero indicates that
this LSP has no corresponding mplsInSegmentEntry.
