This option activates or disables the use of data tunnels (L3 tunnels) between multiple WLCs. This allows you to extend a transparent layer-2 network as an overlay network across the remote WLCs.
Important: Be sure never to bridge the corresponding WLC tunnels if the individual WLCs are located in the same broadcast domain. Otherwise you will create a switching loop that will overload your network.
      Tip: In order to maximize data throughput and the network performance, you can forward the AP data traffic directly into the LAN. In this case there is no need for a layer-3 tunnel between the WLCs even when they are in different layer-2 networks.
