Abstract: A communication method and a communication device. A first donor node generates a first data packet, where the first data packet further includes first information. The first information indicates a donor node to which a destination node of the first data packet belongs, or indicates a network segment to which a destination node of the first data packet belongs, or indicates whether a network segment to which a destination node of the first data packet belongs is a network segment controlled by the first donor node. The first donor node sends the first data packet to the destination node first node.

The configuration information is useable by the terminal device to receive data of the multicast service. The method further includes receiving first indication information from an access network device. The first indication information is useable to indicate a manner of obtaining configuration update information of the multicast service by the terminal device. The manner of obtaining the configuration update information of the multicast service is a first manner or a second manner. The first manner is obtaining the configuration update information by receiving a common message. The second manner is obtaining the configuration update information by receiving a dedicated message.
