Hi, Marek.
Every nodes run the same version of batman.
I attatch the topology of my mesh network.When b0:c6:9b:80:01:53 is on (working),b0:c6:9b:80:01:5f can reach b0:c6:9b:80:01:43,and the hole network is ok.b0:c6:9b:80:01:5b's nexthop to b0:c6:9b:80:01:43 is b0:c6:9b:80:01:57 or b0:c6:9b:80:01:6c, and sometimes b0:c6:9b:80:01:53.
But when I shut b0:c6:9b:80:01:53 down,it seems b0:c6:9b:80:01:5b can't reach b0:c6:9b:80:01:57 neither b0:c6:9b:80:01:6c,as I mentioned in my firt email.
When I turn b0:c6:9b:80:01:53 on again,the hole mesh is ok again.
Marek,can you tell me what the problem probably is.
