Abstract: A packet sending method and device. The first node sets a next-hop of the routing information to a next-hop through which the first node reaches the first route source. The destination address of the routing information is the address prefix. When the second route source is superior to the first route source, the first node switches the next-hop of the routing information to a next-hop through which the first node reaches the second route source. Then, the first node adds, to a target packet, path information of a forwarding path from the first node to the second route source according to the switching operation, where a destination address of the target packet matches the address prefix. Finally, the first node forwards the target packet to the second route source through the forwarding path.

Abstract: This application provides a packet processing method and a related device. An SR policy on a network device includes a segment list, endpoint information, and indication information, and the indication information indicates whether the segment list points to an endpoint indicated by the endpoint information in the SR policy. When receiving a service packet whose destination address matches the SR policy, the network device determines, based on the indication information in the SR policy, whether the segment list points to the endpoint of the SR policy, encapsulates the service packet based on a determining result, and forwards an encapsulated service packet according to an SR path determined based on the segment list.
