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.
