Abstract: This application provides a Example communication methods and apparatus, to improve packet scalability are described. In one example, a method includes: A first node receives a first packet from a second node, and parses the first packet. The first packet includes multicast routing information of the second node, and the first node is a child node of the second node in a multicast tree. A multicast routing identifier of a node is used by a non-leaf child node of the node in the multicast tree to determine multicast routing information of the non-leaf child node, and multicast routing information of a node includes a multicast routing identifier of the node and multicast routing information of a non-leaf child node of the node in the multicast tree.
