FIGURE 18-1 Example Three Topology
Use the following steps to configure the topology shown in Figure 18-1 above:
This section applies only to Access Points in a different subnet from any
Alcatel Mobility Controller. If the Access Points are in the same subnet as the
Alcatel Mobility Controllers, skip this section. This section covers some basic
network configuration required to allow the Access Points to use the Alcatel
Discovery Protocol to discover the Alcatel Mobility Controller over a layer-3
network. There are various methods that can be used by this protocol
(including IP multicast/broadcast, DHCP Vendor Specific Options and DNS
resolution).
1. In this example, configure an IP helper address on the gateway for the IP
addresses of the Access Points with the IP address of the Alcatel Mobility
Controller.
2 Also configure an IP helper address on the Layer-3 switch for the DHCP
server that serves the subnet of the APs.
