More Information
Summary:A method, apparatus and computer program product for providing Routed Split Multi Link Trunking (RSMLT) for Wireless Local Area Network (WLAN) tunnels is presented. A first and second network switch learn data associated with each other, wherein the first network switch and the second network switch operate concurrently. The first network switch terminates a WLAN Tunnel. The data is synchronized between the first network switch and the second network switch, wherein the data includes MAC Addresses, Internet Protocol (IP) interface addresses, Virtual Local Area Network (VLAN) associations, WLAN tunnel assignments and Network switch Internet Protocol (IP) addresses. Load sharing of tunnel data packets is performed by the first and the second network switch. Tunnel control packets received by the second network switch are forwarded to the first network switch over an Inter Switch Trunk (IST).
