The invention discloses a multicast network topology generation method, which comprises the following steps of: 1, setting a configuration file in a terminal computer; 2, the terminal computer logs in each switch through a switch management protocol, inputs basic configuration parameters of m switches, and reads configuration information of the m switches; 3, extracting configuration information of all switches; 4, analyzing and modeling network connection topological relations of all the switches; and 5, inputting the updated routing relation matrix L and the updated multicast forwarding path matrix M to generate a multicast network topological graph. The method is simple in step and reasonable in design, the routing relation matrix and the multicast forwarding path matrix are analyzed, judged and constructed through switch routing configuration information, switch interface configuration information and multicast routing configuration information, and the multicast network topological graph is formed based
