The method includes a first network device receives a first IPv6 packet, where the first IPv6 packet includes a packet header and an inner packet, and the packet header includes a hop limit field. The network device further determines whether a value of the hop limit field is less than or equal to a preset threshold, determines whether the inner packet is a multicast packet, and avoids forwarding the first IPv6 packet when the value of the hop limit field is less than or equal to the preset threshold and the inner packet is the multicast packet.
