On the onther end of that link, i have another interface with IP address XXXX::34:5678 which will join the solicited node multicast address group with the multicast .Spoilers! Suffice it to say we will see some IPv6 solicited-node multicast very much in action.A solicited-node multicast address is formed by taking the low-order 24 bits of an address (unicast or anycast) and appending those bits to the prefix FF02:0:0:0:0:1:FF00::/104 resulting in a multicast address in the range. A Solicited-Node multicast address is formed by taking the low-order 24 bits of an address (unicast or anycast) and appending those bits to the .IPv6 Neighbor Discovery.Die IPv6 RFC 4291 mit dem Schwerpunkt IPv6-Adressen legt fest, dass für jede Unicast- und Anycast-IPv6-Adresse automatisch eine Solicited Node-Multicast-Adresse gebildet wird.The destination address set to the solicited-node multicast group (ff02::1:ff: 66:681f) The source address set to the IPv6 unspecified address (::) If no reply, the host will confirm that the link-local address is unique. FF02::1 is the all node multicast address. So, it is impossible to do more specific filtering.Every IPv6 device will compute a solicited-node multicast address by taking the multicast group address FF02::1:FF /104 and adding the last six hexadecimal characters from its IPv6 address. In IPv6, FF represents multicast.In situations where IPv4 would send a broadcast, IPv6 sends a multicast.
