Dual Homing

"Dual Homing" is a network topology in which a device is connected to the
network by way of two independent access points ("Points of Attachment"). One
access point establishes the primary connection, and the other is a reserve if the
primary connection fails.

Primary and secondary connections, for example, can be connected to the Internet
in different ways. The primary connection could be connected to a physical
network and the secondary to a wireless network. If the "Dual Homing" function
is enabled, a device connects via the primary connection be default, while the
secondary connection remains suspended. If the port or all ports of the primary
connection fail, the devices switches to the secondary connection. If the secondary
connection also fails, the device remains inactive. The secondary connection only
works if the primary connection is interrupted.
