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 WX switch 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 WX switch 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 WX switch 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 WX switch where VLAN Red is configured.
