Abstract: In a packet sending method, a first network device receives a first multicast packet, and determines first information based on the first multicast packet, where the first information indicates an attribute of the first multicast packet. The first network device determines that a state of a first link interface is unavailable, and performs a modulo operation on the first information based on a second parameter, to obtain second indication information, where the second indication information indicates a second link interface through which the first network device forwards the first multicast packet, the second parameter is a quantity of link interfaces whose states are available in a first load balancing group, and the first load balancing group includes the first link interface and the second link interface. The first network device forwards the first multicast packet through the second link interface.
