Nortel WLAN—Security Switch 2300 Series Configuration Guide

In this example, Bob establishes connectivity as follows:

Bob connects to the wireless network at the Corporate Office. The WSS contacts the local Mobility 
Domain seed and finds that the VLAN that Bob is configured to be on, VLAN Red, does not exist in the 
Corporate Office Mobility Domain. 

Unable to find VLAN Red in the local Mobility Domain, the WSS then contacts the local Network 
Domain seed. The Network Domain seed contains a database of all the VLANs configured on all the 
members of the Network Domain. (The Network Domain seed may or may not be the same WSS as the 
Mobility Domain seed.)

The Network Domain seed looks in its database and finds that VLAN Red exists in the Mobility Domain 
at Sales Office C. The Network Domain seed then responds with the IP address of the remote WSS where 
VLAN Red is configured.

A VLAN tunnel is created between the WSS at the Corporate Office and the WSS at Sales Office C.

Bob establishes connectivity on the network at the corporate office and is placed in VLAN Red.
