David,

thanks for the review. I have to admit that I didn't know the PRL option 
existed.

something like this?

  The CE SHOULD include a Parameter Request List Option [RFC2132] for
  the OPTION_6RD.  No more than one instance of the OPTION_6RD DHCP
  option MUST occur in a given DHCP packet.  Provisioning of a CE
  router connected to multiple 6rd domains is outside the scope of this
  protocol specification.

Best regards,
Ole
