Hi Michael, Thanks for sending this along, one of things when I read this article was the firewall not allowing PD traffic thru. I will be adding that was a requirement to this draft. ~Tim On Fri, Jan 13, 2023 at 12:44 PM Michael Richardson <mcr+ietf@sandelman.ca> wrote:

This relates to the desire to amend RFC7084 to support "southbound" DHCPv6-PD:

Alexander Traud tested 29 CPEs and tried to understand how they react to prefix changes.
Router cascade with DHCPv6-PD
With routers connected in a cascade, the internal network can be divided into several zones. This is useful, for example, in shared apartments that want to share an Internet connection, but each resident should still have their own (W)LAN. To do this, the front router, which is directly connected to the Internet, must pass on part of the prefix it received from the provider (DHCPv6-PD, prefix delegation) and its DHCPv6 server must ideally be able to use DHCPv6 reconfigure. Only AVM and Wavlink offered both in the test field.
