Abstract: This application discloses a route information storage method. The method is applied to a wireless mesh network, the wireless mesh network includes a first node, a second node, and at least two stations STAs, the first node is an upper-level node of the second node, the at least two STAs include a first STA and a second STA, and the first STA and the second STA are connected to the second node. In the method, the first node receives a routing request for access requested by the first STA, and if it is determined that a first route entry corresponding to the second STA already exists, the first node no longer generates a new route entry for the first STA, but reuses the first route entry.
