��: Routable IPv4 multicast addresses in bridged scenarios require a 5.14 kernel or newer and "batman-adv 2021.2":https://www.open-mesh.org/news/104 or newer. Before that only supported without bridges.

Otherwise with batman-adv v2019.3 until v2021.1 multicast routers are "guessed" by listeners on ff02::2. Which will "overestimate" by including unicast routers without multicast routing, too. +���: With a 5.14 kernel or newer and "batman-adv 2021.2":https://www.open-mesh.org/news/104 or newer proper "MRD":https://www.rfc-editor.org/rfc/rfc4286.html support is used to detect multicast routers.
