h2. Limitations

- * groups with two or more listeners don't get optimized - * the whole mesh must have multicast support enabled - * optimization for traffic of scope greater than link-local (routable addresses) is not supported yet + * groups with more listeners (+routers) than #multicast-fanout (default: 16) don't get optimized + * optimization for routable IPv4 multicast in bridged scenarios is not supported yet * optimization for link-local IPv4 (224.0.0.0/24) or all-nodes IPv6 multicast (ff02::1) is only done if no node announces BATADV_MCAST_WANT_ALL_UNSNOOPABLES, that is no node configures a bridge on batman-adv. - * high multicast join/leave latency in setups with slow OGM intervals * no awareness for source-specific multicasts * multcast packets over VLANs are always flooded
