L3 Roaming Example
The example in this appendix describes how to configure a D-Link WLAN Controller Switch
for a network that needs L3 roaming capabilities. This example contains information about the
following features, which might be required to use L3 tunneling on your WLAN:
Configuring the WLAN and Tunnel Interfaces
Configuring the L3 Tunnel Network
Configuring DHCP Relay and the DHCP Server
Setting the MTU Size
Configuring the WLAN and Tunnel Interfaces
The following figure shows an example of a network that uses L3 tunnels to support wireless
roaming. The subnet that all clients will use for L3 roaming is 192.168.60.0/24. The
configuration examples in the rest of this appendix use the network information in this figure.
