L3 Roaming Example

L3 Roaming can be achieved by using VLAN trunking (associate the SSID with a VLAN) or

by using an L3 Tunnel (associate the SSID with a tunnel subnet). The example in this

appendix describes how to configure a D-Link Unified Switch by using an L3 Tunnel 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
