How to disable safely the repeat / relay for certain nodes in a Bluteooth mesh network ?

Question

Hi ! 
 My goal is to create a large mesh network (over 100 nodes). 
 I plan to have 3 kind of nodes : a client (connected to a PC), several server relay nodes (not on battery), many server node (on battery, I will call them low power, even though the true low power nodes are not yet available with the SDK). 
 At this point I would like to enable only certain nodes to repeat/relay packets from the "low-power" nodes, in order to avoid a massive flood of the network and to save power. 
 How can I (safely) disable the relay/repeat feature for certain nodes ? 
 Thank!

hello Pseudoincorrect, 
 The Bluetooth Mesh specification allows for the features (Relay, Proxy, Friend etc.) of a mesh node to be dynamically set (enabled/disabled) via use of the Configuration Client and (mandatory) Server models. 
 Within the Nordic Mesh SDK, the config_client_relay_set () function should allow you to achieve your requirement. There aren't any examples in the Mesh v1.0.1 SDK but taking a look at the unit test cases should help you progress. We're working on something similar so if you get stuck, comment back and we can try to help you further. 
 Regards,
