I am testing IPv6 prefix delegation with our testing cnPilot R201. I was able to hand out a WAN IP and delegated prefix, but I had to look at our DHCP server's logs to determine what DUID was being used by the home router. It looks like you're using DUID-LLT by default and the starting time was "Thu Apr 13 03:52:28 1989". Is this setting configurable via provisioning? It'd be more easier on us to use DUID-LL since the DUID is simply 00:03:$hardware_type:$mac_address where $hardware_type could be simply 00:01 for "Ethernet".
