<p>The embodiments of the present invention provide a method for verifying an ARP request message, the method comprises the following step: a gateway receives an ARP request message; if the gateway does not find a matching item for the ARP request message in an ARP cache list, the gateway sends an ARP verifying message of which source internet protocol (IP) address and media access control (MAC) address are a verification IP address and a verification MAC address respectively, wherein the verification IP address and the IP address of the gateway belong to the same network segment and the verification IP address is different from the IP address of the gateway; the gateway receives the first message; if the first message is a response message corresponding to the ARP verifying message, the first message is uploaded to the control plane of the gateway. In addition, the embodiments of the present invention also provide a corresponding device for verifying an ARP request message. The method and device for ARP request message verification provided by the embodiments of the present invention can resolve the problem of some network equipment being unable to access an external network due to ARP request message responses being only in the data plane.</p> |
