Cisco Routers and IPv6 Networking

Say I have 2 routers, 2901 models with just the fast ethernet interfaces in them.
I am wanting to simulate WAN connections between sites. These sites are just theoretical at this time.

Interface FastEthernet 0/0 on Router 1 is given an IPv6 address of 2001:0:1:1::1/64
Router1(Config-if)# ipv6 address 2001:0:1:1::1/64

Interface FastEthernet 0/0 on Router 2 is given an IPv6 address of 2001:0:1:1::2/64
Router2(Config-if)# ipv6 address 2001:0:1:1::2/64

I have enabled dynamic routing on the interfaces using the following commands:
Router1(Config)# ipv6 router rip company
Router1(Config)# interface fastethernet 0/0
Router1(Config-if)# ipv6 rip company enable
Router1(Config-if)# exit

Router2(Config)# ipv6 router rip company
Router2(Config)# interface fastethernet 0/0
Router2(Config-if)# ipv6 rip company enable
Router2(Config-if)# exit

I have IPv4 addresses assigned to the FastEthernet 0/1 interfaces on both routers

Router1# config t
Router1(Config)# interface fastethernet 0/1
Router1(Config-if)# ip address 10.10.10.1 255.255.255.0
Router1(Config-if)# no shutdown
Router1(Config-if)# end

Router2# config t
Router2(Config)# interface fastethernet 0/1
Router2(Config-if)# ip address 10.10.20.1 255.255.255.0
Router2(Config-if)# no shutdown
Router2(Config-if)# end


On each router, I can ping the WAN interface of the other. I cannot ping the internal IPv4 address from the opposite router. I am looking for a way to allow communication between the two networks. Perhaps a NAT64 entry would work best, or perhaps a static route.

Does anyone have a command I could run on both routers to allow a PC on Router 1's Fast Ethernet 0/1 interface to ping and communicate directly with a PC on Router 2's Fast Ethernet 0/1 interface?

Example config's are welcome, I'll keep trying but I am looking to speed up this process.

IPv6 routing is disabled by default on IOS. Enable it with the command "ipv6 unicast-routing" and things should start working as expected.

Here was the fix for the proof of concept. Works great!

Network topology:-    
10.10.10.1 - Router1 - (IPv6) - Router2 - 10.10.20.1


Router1:

interface Tunnel1
ip address 20.20.20.1 255.255.255.0
tunnel source 2001:0:1:1::1
tunnel destination 2001:0:1:1::2
tunnel mode ipv6

ip route 10.10.20.0 255.255.255.0 Tunnel1


Router2:

interface Tunnel1
ip address 20.20.20.2 255.255.255.0
tunnel source 2001:0:1:1::2
tunnel destination 2001:0:1:1::1
tunnel mode ipv6
!
ip route 10.10.10.0 255.255.255.0 Tunnel1

Cisco TAC engineer helped me through this. Works fine. Was able to ping machines on both sides of the routers.
