The router gets the prefix from the ISP, I understand. Everything connected to the router should get that prefix.
Or, everything gets a non-routable prefix instead, and the router does NAT (or something).
I think there is a misunderstanding. I get a /56 prefix from my ISP, i.e. 256 /64 subnets. Hosts directly attached to the router get an address in some /64 subnet (say #00).
Ah! I see.
There I can add another router (my linux-firewall), so its "external" interface gets an address in that first prefix (#00). The "internal" interface gets an address in another /64 subnet (via PD, some subnet other than #00)). And these internal addresses are unknown to the first router (I think, or is there some ipv6 magic ?). radvd should only emit to the internal interface, isn't it ?
I don't know. -- Cheers / Saludos, Carlos E. R. (from 13.1 x86_64 "Bottle" at Telcontar)
