With IPv6 I am most concerned today with receiving an IPv6 address from my ISP for my Spoke networks. I don't have plans to convert my Spoke LANs or Internal application servers to IPV6 anytime soon. Reviewing all the books and technical documentation out there, I don't see discussion about how to get my IPv4 traffic tunneled through the Internet via an IPv6 carrier, a 4to6 tunnel. Currently I'm running DMVPN which appears to support IPv6 tunnels, Native and 6to4. Can anyone provide direction or expertise on how to get IPv4 traffic between Enterprise locations with ISPs move to IPv6 addressing?
Since v4 and v6 can't interoperate, and NAT46 is a really bad idea, your only real option is to dual-stack the customer site, then tunnel the IPv4 traffic over the native IPv6 link. As this (resurrected) thread indicates, this scenario is well supported by Cisco.
