A method and apparatus for using entropy labels in segment routed networks is disclosed. A single ELI and a single EL are provided for a label stack. The ELI and EL are inserted directly below a top-most label in the label stack.A method and apparatus for using entropy labels in segment routed networks. A top-most label of a label stack of a packet is examined. A NHLFE for the packet is determined. A determination is made as to whether or not an ELI is below the top-most label. An EL is re-used when the ELI is determined to be present . The ELI and the re-used EL are inserted directly below a label associated with the NHLFE in a new label stack.
