Customer premise gear has a 'front side' and a 'back side', and it is
already well ingrained behaviour for 'back-to-back port chaining' to
create a single large bridged network in the home. What is the
customer's anticipated result from front-to-back chaining?

That seems much more reliable a hint to me than conditional behaviour.


DHCPv6 PD is applicable to the ISP customer premise. DHCPv6 PD
'chaining' however is probably only applicable in some promised future
where there are alternative home network medias to Ethernet, or to the
Enterprise where the boundaries drawn in broadcast domains are
administrative in nature and not technical (but still, all automated).

DHCPv6PD(PrefixDelegation)にするかブリッジ(RA(RouterAdvertise))にするかはやはり悩むポイント。
法人向けサービスならDHCPv6PDかな。個人向けならRAでもいいじゃん？って個人的に思います。
