Claim 0:
1. A method, comprising:
providing, by a first device and to a second device, information associated with reachability related to at least one next hop;
receiving, by the first device and from the second device, a packet including information associated with a first next hop of the at least one next hop;
decapsulating, by the first device, a header of the packet;
determining, by the first device, based on decapsulating the header of the packet, and based on 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;
removing, by the first device, the header of the packet;
adding, by the first device, 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 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

causing, by the first device and based on the new header, the packet to be routed via a particular path associated with the particular segment routing policy.
