It's as simple as setting up a route to 2002::/16 at the border with a 6to4 conversion.The problem is building a high performance gateway. Currently you have about the following two options: a) set up / configure a Cisco used as 6to4 gateway b) set up a dedicated host (Unix box) as 6to4 gateway Approach a) is good for only few traffic, really.
<reminiscence> You know, I still barely remember when I thought IOS could do just about anything efficiently. Wow, have times changed. </reminiscence> Maybe to start -- but again, what kind of 6to4 traffic level are we expecting yet? It's the chicken and egg all over again.
Approach b) is more complex.
Yes, unfortunately.
I'm waiting for vendor J to enable option c)... implementing 6to4 via the Tunnel PIC (or other PICs including the Tunnel PIC functionalities like Link Services PIC). It's a very simple translation/encapsulation which doesn't require any state keeping, shouldn't be a big deal. I can imagine a few larger IPv6 ISPs then suddenly implementing 6to4 gateways.
The only thing that makes 6to4 more complex, compared to a plain IPIP (or GRE, or any other point-to-point vanilla tunnel protocol) tunnel is that the far-side endpoint changes based on the tunneled payload. That said, it should *not* be an unsurmountable problem -- if the demand is there. Has anyone seen if the chicken laid the hatching egg yet? -- -- Todd Vierling <tv () duh org> <tv () pobox com> <todd () vierling name>
