I am trying to understand if the multicast traffic is sent individually to every registered person on the network even if they are physically on the same LAN.
I am asking this because I am on a wifi manet network and packets needs to be sent only once to save bandwith over the air.
ZeroTier emulates multicast by sending packets to each node listening to a multicast address (up to the max number configured on the network; see “Multicast Limit” on the network config). Unfortunately it won’t be a bandwidth saver for you as there’s no way to encrypt packets to multiple nodes at once, nor does ZeroTier itself utilize multicast as an underlying transport mechanism.
