2. The traffic is intercepted by the home agent in the client’s home network and tunneled to the care-of address in
the foreign network.
3. The foreign agent delivers traffic to the mobile client.
4. Traffic sent by Mobile Client B is also tunneled back to the home agent.

Configuring Mobility Domains
Before configuring a mobility domain, you should determine the user VLAN(s) for which mobility is required. For
example, you may want to allow employees to be able to roam from one subnetwork to another. All Dell controllers
that support the VLANs into which employee users can be placed should be part of the same mobility domain.
NOTE: Dell mobility domains are supported only on Dell controllers.
A controller can be part of multiple mobility domains, although Dell recommends that a controller belong to only
one domain. The Dell controllers in a mobility domain do not need to be managed by the same master controller.
You configure a mobility domain on a master controller; the mobility domain information is pushed to all local Dell
controllers that are managed by the same master controller. On each controller, you must specify the
active
domain
(the domain to which the controller belongs). If you do not specify the active domain, the controller will be assigned
to a predefined “default” domain.
Although you configure a mobility domain on a master controller, the master controller does not need to be a
member of the mobility domain. For example, you could set up a mobility domain that contains only local Dell
controllers; you still need to configure the mobility domain on the master controller that manages the local Dell
controllers. You can also configure a mobility domain that contains multiple master Dell controllers; you need to
configure the mobility domain on each master controller.
The basic tasks you need to perform to configure a mobility domain are listed below. The sections following describe
each task in further detail. A sample mobility domain configuration is provided in "Example Configuration" on page
495.
On a master controller: On all Dell controllers in the mobility domain:
l Configure the mobility domain, including
the entries in the home agent table (HAT)
l Enable mobility (disabled by default)
l Join a specified mobility domain (not required for “default”
mobility domain)
