[lime-users] does multicast optimization fail on ping6?

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?
