ND just uses multicast, so MLD messages are not really part of ND itself. But during the setup of any interface with an IPv6 address, MLD traffic will move and can be snooped on. The switch then knows what listeners are where, so when for example an NS is sent to the solicited node multicast address of a target during ND, the switch can send it only to those hosts it knows are listeners on that group.
