And at the destination encapsulates it back to IPv6? Yes/No?
Yes and No. It depends. You're talking about tunneling IPv6 packets around, and that does require both ends to be configured. If only one end supports it, the tunneled IPv6 packet will just be dropped upon arrival. I believe there is even a NAT configuration for doing IPv6 to IPv4 and vice versa. They've been trying all kinds of methods to get them to work together so they can start a transition. Supposedly some IPv6 addresses have been allocated, but you're probably not going to see them any time soon.
