3 Scenario 3 – L3 Overlay: 1 WS + 1 AP + 1 Remote AP
The diagram in this section shows a network configuration with a D-LINK Wireless
Switch connected to an L3 Device/Router. One AP is connected to the D-LINK Wireless
Switch, and the other is connected to the L3 device. Both APs are managed by the D-
LINK Wireless Switch (WS1).
This scenario uses L3 tunneling so that a client that associated with AP1 initiates an
audio conversation and roams to a different subnet. In the process, the client is
disassociated with AP1 and gets associated with AP2 maintaining the audio conversation.
This scenario is especially useful for you to setup a demo in customers’ existing network
with little change to customers’ network configuration.
The objectives for this scenario include the following:
•
To know how to setup the L3 tunneling (L3 Tunneling must be used since the
APs are on different IP subnets and there is not a L2 path between the APs for the
WLAN Network data).
•
To know how to manage the remote AP and the most practical deployment into
customers’ existing networks.

In this scenario, the L3 device is part of the customer network. The L3 device must meet
the following minimum requirements:
•
One network to connect to the WS switch (in this scenario, the network is
172.17.5.0/24)
•
One network to connect to AP2 (in this scenario, the network is 172.17.6.0/24)
•
DHCP server in the AP2 network for AP and wireless client addresses
