We also experienced this behavior. By default (if using lime-build) the
multicast feature is disabled to prevent this problem.
Not sure if the batman-adv guys will do something to add this
"exception" but you can try :)

Hi all,
when we first tried to install libre-mesh (on a ubnt bullet and a
picostation, but that's not the point) we were confused by the fact
that the usual
ping6 ff02::1%eth0
that we do in order to discover the addresses of the available devices
in the net was NOT working as expected, it was like each device was
isolated from the rest of the net.
We identified the problem with the multicast mode of batman-adv, in
fact with
batctl multicast_mode 0
everything works fine again.
Can anyone reproduce this behavior?
According to
http://www.open-mesh.org/projects/batman-adv/wiki/Multicast-optimizations
it seems that batman drops the data when there are no listeners.
A multicast ping6 actually doesn't have registered listeners, so it
seems an exception to the rule, shall we file a bug in batman-adv or
are we missing something?
