One more thing, I call this "scalable de-aggregation". It is a refinement of what first appeared in RFC6179. Thanks - Fred fred.l.temp...@boeing.com > -Original Message- > From: ipv6-ops-bounces+fred.l.templin=boeing@lists.cluenet.de > [mailto:ipv6-ops- > bounces+fred.l.templin=boei

Hi Nick, More on this, please see Section 3.7 on the AERO Routing System (2 pages). It tells how the DHCPv6 relay can inject delegated prefixes into the routing system without imparting unacceptable churn and while allowing scaling to many millions of delegated prefixes. There is a terminology

Wait, Wait! So your telling me that it's wrong for DHCPv6 servers to feed default gateways to endpoints because "who better than the router to know whom to route too" but for DHCPv6-PD we should rely on the DHCPv6 servers to do route injection? This is classic! just classic! Take this back to t
