Disclosed is a neighbor topology discovery method for multi-interface terminals, used for improving the usage rate of multiple interfaces. The method comprises the following steps: after joining in networks, the multi-interface terminal broadcasts a neighbor discovery request message to respective networks via respective interfaces, the neighbor discovery request message carrying a neighbor hop value; the multi-interface terminal in the networks monitors broadcast messages from other terminals in the networks where the interfaces are located; when detecting a neighbor discovery request message, if the neighbor hop value carried in the detected neighbor discovery request message indicates that the terminal is the last hop, the multi-interface terminal extracts related information in the neighbor discovery request message, and updates the neighbor information and network topology information of the terminal; and if said neighbor hop value indicates that the terminal is not the last hop, the multi-interface terminal further modifies the neighbor hop value and then forwards the neighbor discovery request message via all the interfaces. |
