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.
