For this, a multicast address is used, formed from the network prefix ff02 : : 1 : ff00 : 0 / 104 and the 24 least significant bits of the address.

A bridge sends a BPDU frame using the unique MAC address of the port itself as a source address, and a destination address of the STP multicast address 01 : 80 : C2 : 00 : 00 : 00.

Depending on the state of the sending interface and the source of the advertisements being acknowledged, a Link State Acknowledgment packet is sent either to the multicast address AllSPFRouters, to the multicast address AllDRouters, or as a unicast.

25.
A Solicited-Node multicast address is created by taking the last 24 bits of a unicast or anycast address and appending them to the prefix ff02 : 0 : 0 : 0 : 0 : 1 : FF00 : : / 104.

Because a solicited-node multicast address is a function of the last 24-bits of an IPv6 unicast ( or anycast ) address, the number of hosts that are subscribed to each solicited-node multicast address is very small.

A number of errors can happen if packets intended for unicast are accidentally sent to a multicast address; in particular, sending ICMP packets to a multicast address has been used in the context of DoS attacks as a way of achieving packet amplification.

In the SSM service model, in addition to the receiver expressing interest in traffic " to " a multicast address, the receiver expresses interest in receiving traffic " from " only one specific source sending to that multicast address.
