Abstract
This application provides a packet forwarding method, device, and system. The method includes: A first network device obtains a first packet, where the first packet includes a multicast packet; the first network device determines a next-hop destination address DA of the multicast packet based on a source address SA and a first correspondence relationship, where the SA is used to identify a multicast path corresponding to the multicast packet, and the first correspondence relationship includes the SA and a next-hop DA of the first network device on the multicast path; the first network device obtains a second packet based on the next-hop DA, where the second packet is a unicast packet obtained after IPv6 encapsulation is performed on the multicast packet; and the first network device forwards the second packet along the multicast path based on the next-hop DA.
