Using the current implementation with bla and dat enabled, several problems= can be observed in a real setup: 1. Multiplication of ARP replies from dat enabled gateways and dat enabled = mesh nodes leading to an "ARP reply storm" in the common backbone network. 2. In rare corner cases bla does not fully prevent looping of unicast frame= s in the direction backbone --> mesh --> backbone and looping of multicast = frames in the direction mesh --> backbone --> mesh. The latter can lead to temporary confusion in the switched backbone resulti= ng in packet loss and communication timeouts. The observed problems are solved by introduction of additional rules for th= e dat handling, bla packet forwarding and bla claiming/unclaiming of client= s. ..................................................................
