Link Required for Backing Up Root Access Point

This section shows how to use the Link Required option so that designated WLAPs can roam to
another root access point if the original one loses its Ethernet connection. In Figure 4-5, access
points B and C are initially the designated WLAPs for root access point A. When access point A's
Ethernet connection is broken, access points B and C reset then to roam to access point D.
Furthermore, if access point D loses its Ethernet connection and access point A's Ethernet
connection is restored, WLAPs B and C roams back to access point A.
