Claim 7:
8. A first device, comprising:
one or more memories; and
one or more processors to:
provide, to a second device, information associated with reachability related to at least one next hop;
receive, from the second device, a packet including information associated with a first next hop of the at least one next hop;
decapsulate a header of the packet;
determine, based on decapsulating the header of the packet, and based on the information associated with the first next hop, that the packet is to be routed based on a particular segment routing policy, of one or more segment routing policies associated with the first device;
remove the header of the packet;
add, without performing a lookup process and based on determining that the packet is to be routed based on the particular segment routing policy, a new header to the packet,
wherein the new header includes at least one of a first segment identifier list that identifies a first path associated with the first next hop of the at least one next hop or a second segment identifier list that identifies a second path associated with a second next hop of the at least one next hop, and
wherein the new header further includes a first destination address associated with the first segment identifier list or a second destination address associated with the second segment identifier list; and

cause, based on the new header, the packet to be routed via a particular path associated with the particular segment routing policy.
