Nicolas, FR switch DOES NOT participate in inverse ARP processes. Only end-nodes (FR DTE devices) do. Your router sent a "question" on all DLCIs asking routers to tell it what are their IPs. They obliged and you got that information. They don't have to be on the same subnet, as inverse ARP is unaware of subnets. It just reports what it hears.
