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.
