The embodiment of the invention discloses a method and a device for realizing multi-next-hop routes, the method comprises the following steps: running a route algorithm, and calculating routes from network nodes to other network nodes in a network; obtaining a neighbor list of target nodes of the network nodes; merging the routes from the network nodes to the target nodes and the routes from the network nodes to neighbor nodes in the neighbor list according to the calculated routes as a set of available multi-next-hop routes from the network nodes to the target nodes. The multi-next-hop routes obtained by applying the embodiment of the application can increase the number of the available multi-next-hop routes to the target nodes and increase the routes for being selected by the network nodes, compared with the prior art, the multi-next-hop routes can further improve the utilization rate of network resources.
