More IPv6 Tunneling

So moving on from my last post, and before doing a little write up on IPv6 tunneling I thought I'd do one more scenario. So very similar to the last issue, we have an IPv4 only WAN and we want to dynamically tunnel IPv6 traffic over said WAN.

Restrictions/Requirements:
- Do not modify tunnel mode
- Do not add any additional static routes
- Do not introduce an IPv6 dynamic routing
- When the task is complete you should be able to successfully ping 2002:A0A:A02::1:2 and 2002:A0A:A03::1:3 on R1 sourcing from Lo0.
