Does Batman Adv provide correct mcast routing for link-local mcast groups?
I guess I am confused then... I am trying to see my avahi services on the other side of a hop. the middle node sees the services of both ends, but the ends do not see the services of each other. After talking to the Avahi users group, they seemed to think this had something to do with batman advanced implementation of its mcast routing. If you say they are flooded through the network, is there another reason why I wouldn't see the mDNS broadcasts over the hop?
Thanks

Yes, all multicast packets are simply flooded through the whole network.

So, you have 3 nodes (let's call them A/B/C) in a row. A sends mDNS data, B receives it but C does not ? The best starting point is "batctl td" or wireshark which allow you to inspect the packets. You could verify what happens with your broadcasts. Feel free to post your logs here.

One quick thing that comes to my mind is, that you can specify allowed or denied interfaces in avahi. Maybe it has chosen the wrong ones? (should probably be bat0 and not the direct wlan0 interfaces for example) Of course this is just an assumption in case batman-adv itself works perfectly well. :)
