Claim:
A method of updating proxy information in a mesh network, the method comprising: transmitting a first multi-hop management frame of a source mesh point (MP) to a destination MP via a first mesh path, the first multi-hop management frame comprising a proxy update information to inform the destination MP about proxy information of at least one external address that is reachable through a proxy MP; and receiving a second multi-hop management frame from the destination MP via a second mesh path, the second multi-hop management frame comprising a proxy update confirmation information to inform the source MP that the proxy update information is properly received by the destination MP, wherein the proxy update information comprises a flags field indicating whether the proxy information is added or deleted, a proxy address field indicating a medium access control (MAC) address of the proxy MP, a proxy update sequence number indicating a sequence number of the proxy update information, and a proxied address field indicating a MAC address of a station proxied by the proxy MP, and wherein the proxy update confirmation information comprises an address of the source MP that originates the proxy update information, wherein the sequence number of the proxy update information is incremented by 1 before the proxy update information is transmitted to the destination MP, and wherein the destination MP updates proxy information of the destination MP when addresses in the proxied address field and the proxy address field do not exist at the destination MP and when a value of the sequence number of the proxy update information is larger than a value of a sequence number in the proxy information of the destination MP.
