Figure 5. How a user connects to a remote VLAN in a network domain

In this example, Bob establishes connectivity as follows:
1Bob 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.
2Unable 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.)
3The 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.
4A VLAN tunnel is created between the WSS at the Corporate Office and the WSS at Sales Office C.
5Bob establishes connectivity on the network at the corporate office and is placed in VLAN Red.
