In the era of the early ipv6 networks it was  necessary to build tunneled overlays or employ transitional technologies e.g. 6to4 or teredo to support transitional ipv6 hosts. these are to be contrasted with cases where the support of IPv6 is intrinsic (native if you will) to the network control and forwarding architecture. native as used at the time implies more about the state of the network at the time then it does today. it was common at the time to refer to inter domain multicast using pim and bgp as native multicast as compared to the previously tunneled mbone.
