how to create site to site tunnel vpn on IPv6, and route IPv4 network

i want to do this scenario
 

Site1:

LAN1: 192.168.1.0/24,

where router cisco is 192.168.1.1 -> fa0/1

WAN1: running on IPv6: FD00::1/8 -> fa0/0

 

Site2

LAN2: 192.168.2.0/24, 

where router cisco is 192.168.2.1 -> fa0/1

WAN2: running on IPv6: FD00::2/8 -> fa0/0

 

There is a direct conneciton between Site1 & Site2 on WAN interfaces.
On both sites, there are running IPv4 hosts/devices.


Now, i want to create site to site connection, to route IPv4 traffic between these two sites.
i want create ipv6 tunnel interfaces, and i want to add ip sec encryption also.

How can i do this?
Regards!

There will be approximately 70 sites.

Well, 70 sites is slightly

Well, 70 sites is slightly more then the two sites you were talking about before. But with a scalable authentication like certificates and a half day of hard work it would still be possible to configure the 70 tunnel interfaces on the hub.

But with that amount of sites, FlexVPN could be the better choice:
