MplsLSPID ::= TEXTUAL-CONVENTION
   STATUS        current
   DESCRIPTION
       "An identifier that is assigned to each LSP and is
        used to uniquely identify it.  This is assigned at
        the head end of the LSP and can be used by all LSRs
        to identify this LSP.  This value is piggybacked by
        the signaling protocol when this LSP is signaled
        within the network.  This identifier can then be
        used at each LSR to identify which labels are being
        swapped to other labels for this LSP.  For IPv4
        addresses this results in a 6-octet long cookie."
   SYNTAX        OCTET STRING (SIZE (0..31))

-- An MPLS label.
MplsLabel ::= TEXTUAL-CONVENTION
   STATUS        current
   DESCRIPTION
       "This value represents an MPLS label.  Note that the
        contents of a label field are interpreted in an
        interface-type specific fashion.  For example, the
        20-bit wide label carried in the MPLS shim header is
        contained in bits 0-19 and bits 20-31 must be zero.
        The frame relay label can be either 10 or 23 bits
        wide depending on the size of the DLCI field and
        bits 10-31, or 23-31 must be zero, respectively.
        For an ATM interface, bits 0-15 must be interpreted
        as the VCI, bits 16-23 as the VPI and bits 24-31
        must be zero.  Note that the permissible label
        values are also a function of the interface type.
        For example, the value 3 has special semantics in
        the control plane for an MPLS shim header label and
        is not a valid label value in the data path."

   DESCRIPTION
       "A row in this table represents one cross-connect
        entry.  The following objects index it:

        - cross-connect index mplsXCIndex that uniquely
          identifies a group of cross-connect entries
        - interface index of the in-segment,
          mplsInSegmentIfIndex
        - incoming label(s), mplsInSegmentLabel
        - out-segment index, mplsOutSegmentIndex

       Originating LSPs:
        These are represented by using the special
        combination of values mplsInSegmentIfIndex=0 and
        mplsInSegmentLabel=0 as indexes.  In this case the
        mplsOutSegmentIndex MUST be non-zero.

       Terminating LSPs:
       These are represented by using the special value
        mplsOutSegmentIndex=0 as index.


       Special labels:
        Entries indexed by reserved MPLS label values 0
        through 15 imply terminating LSPs and MUST have
        mplsOutSegmentIfIndex = 0.  Note that situations
        where LSPs are terminated with incoming label equal
        to 0, should have mplsInSegmentIfIndex = 0 as well,
        but can be distinguished from originating LSPs
        because the mplsOutSegmentIfIndex = 0.  The
        mplsOutSegmentIfIndex MUST only be set to 0 in
        cases of terminating LSPs.

        An entry can be created by a network administrator
        or by an SNMP agent as instructed by an MPLS
        signaling protocol."
