ExtremeCloud IQ Controller supports tunneling traffic between access points without traversing the controller. Generic Routing Encapsulation (GRE) offers direct, point-to-point communication between network nodes with support for one to three termination points. This option steers tunneled traffic to destination points other than the default controller and offers support where other tunneling options like VxLAN and Fabric Attach are not a consideration.
APs establish a GRE tunnel with the defined target termination point and directly bridge traffic to and from clients associated to the topology. The data path for wireless client traffic can now travel to a separate data center without involving a controller.
