Maybe my mail was not clear enough that this problem exists because the payload traffic loops, not the batman-adv protocol traffic. As you correctly pointed out the OGMs are filtered and dropped if necessary. By the way, this is not a problem unique to batman-adv. Ethernet loops are a common problem in bridged / switched environments. Feel free to search for "bridge loop" or "ethernet loop" to find some interesting examples. Regards, Marek
