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: Techniques are described for provisioning non-colored segment routing label switched paths (LSPs) via segment routing policies in border gateway protocol (BGP). For example, an ingress router receives a segment routing policy advertisement specifying an endpoint of one or more paths, and a policy color field of the one or more paths, wherein the policy color field is specified with a designated value that causes the network device to store the one or more paths in a data structure that stores non-colored paths. The ingress router determines that the policy color is specified with the designated value. The ingress router, in response to determining that the policy color is specified with the designated value, stores the one or more paths in the data structure that stores non-colored paths.
