Abstract: A network device may receive a packet and may determine whether a next header of the packet is an Internet protocol (IP) header, an Internet control message protocol (ICMP) header, or a segment routing header. The network device may determine, when the next header of the packet is the IP header, whether policy processing of the packet is set to ultimate segment decapsulation and may discard the packet when the policy processing of the packet is not set to ultimate segment decapsulation. The network device may decapsulate an outer header of the packet when the policy processing of the packet is set to ultimate segment decapsulation and may process the packet after decapsulating the outer header of the packet, to generate a processed packet. The network device may forward the processed packet toward a destination.

Abstract: A first network device may receive an advertisement that includes a prefix for a second network device, wherein the advertisement is destined for a third network device. The first network device may determine, based on a network topology, whether a next hop is one hop away or multiple hops away. The first network device may selectively modify the advertisement to include a first segment identifier, based on the next hop being one hop away and to generate a first modified advertisement, or may modify the advertisement to include a second segment identifier, based on the next hop being multiple hops away and to generate a second modified advertisement. The first network device may forward the first modified advertisement or the second modified advertisement toward the third network device.

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.
