Abstract
A method, apparatus and computer program product for providing failover for a point to point tunnel for wireless local area network split-plane environments is presented. A second network switch learns first data associated with a third network switch and the second network switch terminates a tunnel. The third network switch learns second data associated with the second network switch. The first and second data are synchronized between the second network switch and the third network switch. The second network switch and the third network switch load sharing tunnel data packets. The third network switch forwards tunnel control packets received by the third network switch to the second network switch. A failure relating to the second network switch is detected and a new tunnel is established with the third network switch.
