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