Yes, it's very far-fetched, because in this specific scenario: 1) the access network is usually the most difficult part to get native v6, and 2) it's much simpler for all the concerned parties for the ISP to use internal tunneling to bridge the gaps in its core network. Whether these tunnels are manually configured, set up automatically using 6PE ("BGP-tunneling") between the border boxes, etc. makes little difference. It's very simple to provide v6 support across v4 core if your edge device supports v6 already. So, as stated -- I'm having a lot of trouble figuring out the real applicability of this option, and I don't think we should go forward with it. The danger is that it's more confusing than it's worth... -- Pekka Savola "You each name yourselves king, yet the Netcore Oy kingdom bleeds." Systems. Networks. Security. -- George R.R.
