Redmine batman-adv - Bug #194 (Closed): multicast_mode appears to block avahi traffichttps://www.open-mesh.org/issues/1942014-09-11T19:52:13ZBill Richardsonwbr@mac.com
<p>Not sure if this is a batman-adv issue or a kernel, avahi, or openwrt issue...</p>
<p>I've been running OpenWrt r40555 on a handful of ar71xx routers all connected with batman-adv. Avahi has been working great across the mesh, until I updated the firmware on the routers to Barrier-Breaker 14.07.rc2 (r42087). Everything works as expected, except for the forwarding of avahi packets. Avahi now works within the space of a single router but not across the batman-adv mesh.</p>
<p>Batman-adv on the latest rev of OpenWrt has been updated to 2014.2.0 and introduces "multicast_mode" for the first time on OpenWrt. When I disable multicast_mode in batman-adv, my avahi traffic across the mesh works again. With the new multicast_mode enabled (batman-adv's default), avahi does not work across the mesh. It looks as though multicast_mode is blocking the receipt of mdns responses, not the sending of mdns queries.</p>
