Hi, I need some clarification on the basis of which i can proceed with my work. I have two Access Points and one station. Station is in the range of both AP. Both access points have same BSSID, same MAC address and same channel, but station can be associated with one AP at a time and only that AP will forward frames for the station. When station transmit the frame the receiver address is the MAC address of the AP. Altough the second AP has the same MAC address, it simply discards the packet because it could not find the station in its association table. If somehow I add the MAC address in the association table of second AP, will it forward the frames for the station or not. (Don't worry that there will be two copies, offcourse there will be a central point of decision which will in the end discard the extra copy). Is my assymption true that if MAC address of station is in the association table of an AP, it will not discard the frames from that station and will forward it?? Please need a sincere reply because on this basis i will start my work. Thank you so much.

From: "Praveen Mehrotra" <pra...@gm...> The mechanisms for doing what you want would be similar to handling associated client data. Assuming all AP's have exchange information about a new client (using some xyz mechanism), each AP may insert that client in a node-queue (which probably should be different from queue used to track associated clients). You can keep track of clients in 2nd queue using sysctl. When client actually roams to a new AP, you would probably need to manipulate node queues again so that now client shows up in associated node-q.

Hi, It might just be me missing something, but two devices (two L2 interfaces) having the same MAC address sounds like a really bad idea. Surely the whole point of a MAC address, that it's unique. Switches are going to have a fit if you have both AP's on the same L2 network. Dan...
