The present invention provides a neighbor topology discovery method for a multi-interface terminal, to improve the usage rate of multiple interfaces. The method includes the following steps: after joining a network, the multi-interface terminal broadcasts a neighbor discovery request message to respective networks via each interface, and the neighbor discovery request message carries a neighbor hop value; and the multi-interface terminal in the network monitors broadcast messages of other terminals in the network where each interface is located; when detecting the neighbor discovery request message, if the neighbor hop value carried in the detected neighbor discovery request message indicates that the present terminal is the last hop, then related information in the neighbor discovery request message is extracted, and neighbor information and network topology information of the present terminal is updated; and if the neighbor hop value indicates that the terminal is not the last hop, then the neighbor hop value is further modified and then the neighbor discovery request message is forwarded via all the interfaces. |
