Per these discussion records before and the > personal feedback from Adrian (RTG-AD), my conclusion (or impression) > sounds that 'use DHCPv6 to add & withdraw route on the PE router' Well yes and no, depends how it is expressed. On one hand, the DHCP software on the Relay should insert a route whenever a Prefix is allocated by PD - otherwise later application-layer packets are not forwarded from that prefix through that Relay. Maybe the route entry should expire when the prefix lifetime expires. PD through a Relayed topology is useless otherwise. It would be as if an address were allocated with DHCP but the firewall blocked that address. On another hand, an explicit DHCP message to add routes (as seems to imply the wording 'use DHCPv6 to add route on the PE router') approaches more the meaning that may be controversial. Because that is the typical what routing protocols do, and in the particular case of default routes, it is the typical action of ND.
