Hi Ted, But there’s no reason for an overlay topology. The question is, is there a way for it to know which stations to send the multicast too? If so, then it should just iterate across that set of stations using unicast, which is a lot faster. If not, then it probably has no choice but to broadcast. Sorry if these are naive questions—I haven’t really dug around in the details of how WiFi routers do multicast, so I have just enough knowledge to appear really ignorant. With my NBMA case, there is a an overlay routing system which has proactive full knowledge of all active nodes on the link and knows how to unicast-forward to any of those nodes at any time. In the WiFi base station case, unless there is some way for the base station to learn the list of active nodes on the link then broadcast is the last resort. Or, the base station could start out life with a NULL topology table and then add new nodes as it receives multicasts. Then, as its topology table grows, it may be able to eventually start to do unicasts to those nodes it has previously learned about from broadcasts – a learning bridge, in other words – useful? Fred
