Embodiments of the present invention relate to a method for determining a multicast path, a method for receiving a data packet, and a router. The method for determining a multicast path includes: receiving, by a multicast address translation router, a first multicast join request packet, where the first multicast join request packet is an IPv4 packet, or the first multicast join request packet is an Internet Protocol version 6 IPv6 packet and a multicast address of the first multicast join request packet is an IPv6 multicast address obtained by performing Internet Protocol version translation on an IPv4 multicast address; and determining, by the multicast address translation router, a shorter path between a first path and a second path. The multicast address translation router may determine the shorter path between the first path and the second path, where both or either of the first path and the second path separately belongs to different network types, thereby implementing a method for selecting a shorter path from the paths of different network types, which improves multicast efficiency. |
