Classification: CPC H | IPC H

Claim 8:
9. A device used in a communication network comprising:
at least one processor;
one or more memories coupled to the at least one processor and storing instructions for execution by the at least one processor, wherein the instructions instruct the at least one processor to cause the network device to:
determine a second route source being superior to a first route source, wherein both the first route source and the second route source are nodes for advertising an address prefix;
based on the second route source being superior to the first route source, add first explicit path information to a target packet, wherein a destination address of the target packet matches the address prefix, and the first explicit path information is used to indicate a forwarding path from the network device to the second route source, the first explicit path information comprises one or more of the following: a prefix label or a node label of the second route source, a node label or a prefix label of a node on a first forwarding path, and a link label of a link on the first forwarding path, and the first forwarding path is a forwarding path from the network device to the second route source; and
forward the target packet to the second route source through the forwarding path, wherein the target packet comprises the first explicit path information.
