Hello, in my lab we recently started playing with some OpenWrt powered radios an we tried to do a mesh configuration using the 802.11s protocol, I was looking for suggestion about ways to detect the topology. I thought about sniffing traffic at the pcap level expecting that the mac address of incoming packets would be changed to be one of the neighboring radios but I noticed that source mac addresses are preserved between hoops (I still need to double check this but I am fairly sure it's happening).

Does anyone have any better idea? Is there any way to query the network interface to obtain some sort of IDs of the radios that are in range?
