The output of show ipv6 interface command lists the multicast addresses used by the router on the interface. In this case, the highlighted multicast addresses include FF02::1 (all nodes), FF02::2 (all routers), and FF02::A (EIGRPv6). ////
We will briefly discuss solicited-node multicast addresses to round off the coverage of IPv6 addressing in this chapter. These addresses provide a destination address so that one packet can be sent in an IPv6 subnet with link-local scope to all hosts whose unicast addresses have the same value in the last six hexadecimal digits. In other words, the solicited-node multicast address for a particular host is a multicast address with link-local scope based on only the last six hex digits of the unicast IPv6 address of the same host. All host having the same value in the last six hex digits of their IPv6 unicast addresses, will have the same solicited-node multicast address. Each host must listen for IPv6 packets sent to its solicited-node multicast address.

Let’s have another look at the output of show ipv6 interface command shown earlier as well. The last two multicast addresses highlighted below are solicited-node multicast addresses!
