unable to assign ipv6 address to interface to get ipv6 on lan side

[clintonstrouth]

I'm unable to assign an ip address within my /64 to allow the services off of Fa0/1 to connect via ipv6 tunnel,
The tunnel is working on the router its self
edge-rtr(config)#int Fa0/1
edge-rtr(config-if)#ipv6 address 2001:470:1F11:F5F::3/64
% 2001:470:1F10:F5F::3/64 can not be configured on FastEthernet0/1, overlapping

edge-rtr(config)#int Fa0/1
edge-rtr(config-if)#ipv6 address 2001:470:1F11:F5F::2/64
% 2001:470:1F10:F5F::2/64 can not be configured on FastEthernet0/1, in use


I do have a routed /48 however i just figured I could use the addressing off of the /64

Routed /64:2001:470:1f11:f5f::/64
Routed /48:2001:470:c26b::/48

any suggestions would be greatly appreciated.

It looks like you missed a/64?   There should also be a tunnel /64...

[clintonstrouth]

This has been resolved, the tunnel details page did not load correctly yesterday for me and was not showing the tunnel ptp details to correctly configure the point to point link.

Thanks for your help cholzhauer as i was working on this with very little sleep.
