Abstract:
The present application provides a communication method and device, for use in improving the scalability of a message. The method comprises: a first node receives a first message from a second node, and parses the first message. The first message comprises: multicast routing information of the second node, and the first node is a subnode of the second node in a multicast tree. A multicast routing identifier of one node is used for a non-leaf subnode of the node in the multicast tree to determine multicast routing information of the non-leaf subnode, and multicast routing information of one node comprises: the multicast routing identifier of the node and the multicast routing information of the non-leaf subnode of the node in the multicast tree.
