Secure wireless bridge

[jmprats]

I want to establish a secure wireless bridge (with a root bridge and one non root bridge). I can set in the non-root which is the MAC address of the parent, but how can I set in the root bridge with MAC is the non-root one ? I want to avoid other non root bridges can connect to the parent

Thanks

Have an encryption running between the bridges. This way even if a unknown nonroot gets associated to the root, you will not be able to transmit or recevie data if the encryption keys are incorrect, and we have control over the encryption keys
