This is the Neighbor Cache which maps the unicast IPv6 address to the Link Layer Address. The structure also contains the necessary information to execute the Neighbor Unreachability Detection Algorithm.
Since interfaces can have multiple IPv6 addresses. It is possible that there can be multiple Unicast IPv6 addresses being mapped to a single LLI6 entry.
