Abstract:
A network device may receive an MPLS packet destined for a destination via a label-switched path (LSP), and may determine whether to apply a first special purpose label (SPL) option or a second SPL option for a label stack of the MPLS packet. The network device may apply, when the first SPL option is determined to be applied, one of a first type of the first SPL option for the label stack via a policy data indicator (PDI) and policy data (PD), or a second type of the first SPL option for the label stack via the PDI and the PD. The network device may forward the MPLS packet to a hop of the LSP based on the first type of the first SPL option or the second type of the first SPL option applied to the MPLS packet.
