Oh, customer *routers*.  Are you sure they have IPv6 enabled?

The typical process for customer routers (like AVM Fritz!Box) is:

 - RA is used to tell the router about router IPv6 address + default route
   (or the default route is just set to the outgoing PPP interface, for
   PPPoE/PPPoA interfaces with active IPv6CP)

 - DHCPv6 PD is used to get customer prefix

In your case, with ETTH, I think you'll have to check with the router
vendor to see what is happening - hard to say anything useful without
knowing the model and whether that one is IPv6 capable at all...
