How is neighbor solicitation done in IPv6?

There are another two types of neighbor discovery message exchanges called NS — Neighbor Solicitation and NA — Neighbor Advertisement. These are similar to the ARP process in IPv4, where nodes need to learn link-layer addresses (MAC address) before communicating with each other. In IPv6, it is done via NS and NA messages. Neighbor Solicitation (NS)
