IPV6 addressing and ICMP

To All,

I have a simple IPv6 problem with two ethernet interfaces that I am unable
to ping one another. I setup two /64 address to two directly ethernet
interfaces and when I attempt to ping will not work and I am not sure why?
The IP addresses work fine. Must I do something on the switches
interconnecting the two. I ran debug ipv6 packet and debug ipv6 icmp and it
tells me that encapsulation failed???? Can someone shed some light on what
the problem may be

R3
ipv6 cef
!
ipv6 unicast-routing
!
int ethernet0/0
ip address 139.1.0.3 255.255.255.0
ipv6 address 2001:CC1E:1:10::3/64

R6
!
ipv6 cef
!
ipv6 unicast-routing

int ethernet0/1
ip address 139.1.0.6 255.255.255.0
ipv6 address 2001:CC1E:1:10::6/64

DEBUG OUTPUT
