IPv6 via Transfernetwork

[AJH]

Hi together,

I have the following situation:

							<-> DHCP SERVER (via RELAYFUNCTION)
CLIENTNETWORK <-> CLIENTROUTER <-> PROVIDERROUTER 
							<-> INTERNET

I like to give the CLIENTROUTER a fixed /64 IPv6 adress
which is direct connected to the PROVIDERROUTER -> as trasnfer net

Also I like to give the CLIENTROUTER a /56 IPv6 prefix

Does anyone know how this have to be configured onto
the PROVIDERROUTER (CISCO). 

I think he have to learn which /56 prefix is delegated
to which /64 address 

Thanks a lot for ideas...
