For example, the label carried in the MPLS shim header is 20 bits wide and the top 12 bits must be zero. The frame relay label can be either 10, 17 or 23 bits wide depending on the size of the DLCI field size and the top 22, 15, or 9 bits must be zero, respectively. For an ATM interface, the lowermost 16 bits are interpreted as the VCI, the next 8 bits as the VPI and the remaining bits must be zero. Also note 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 datapath." REFERENCE "1.
