Help with more complex (odd) network

Hi is anyone out there any good with networks and how to set up complex one completely out of the norm?

Specifically I have 3 WiFi mini router/ WiFi extenders I need to get IP from the 3rd one to the 2nd to the master. I'm about 95% there with it but as I'm just learning as I go on it would be useful to have a expert confirm that I haven't gone down the garden path. I have found it best to have 3 sperate SSID's and have used the master one to reserve the others IP. There is alot more to explain if anyone is interested in lending a their brains :slight_smile:
