R1's solicited node multicast address is FF02::1:FF:12:3456.
R1's 2000::4:213:19FF:FE12:3456 address is a global unicast with all 128 bits statically configured.
Address FF02::2 is R1's solicited node multicast.
R1's solicited node multicast, not listed in this output, would be FF02::213:19FF:FE12:3456.
