Autoip on DHCP server


I am running debian on the BBB. I have the device setup as a DHCP server on

One of the devices that connect need to be able to fall back to connecting to the BBB via autoip should it not get an IP address from the dnsmasq.

I have installed avahi-autoipd but I am not sure how to fit everything together.

As my BBB eth0 already has an ip address off (as I set it up being the server) how does it also provide an autoip address of 169.254.something.

Hope some one can help
