I know that there is no broadcast in IPv6. However, there is the concept of link-local multicast using the ff02::1 IP address, reaching all hosts in the very same local network.

So what is the difference between ff02::1 and IPv4 broadcast? Since routers do not forward broadcast packets in IPv4, from my point of view, the behavior of those two concepts is identical?

  • Given that ff02::1 is allowed to be mapped to the broadcast MAC ff-ff-ff-ff-ff-ff, there might be no difference... – user1686 Jul 28 '16 at 17:42
  • Indeed there is no difference – Whymarrh Jun 4 '17 at 0:29
