[c-nsp] DHCP_PD usage for PPPoE Access

[Frank Bulk]

Based on what I've seen of residential IPv6 CE routers, that would be a very
unusual configuration, in fact, perhaps impossible.

There's always a customer that bridges the PPP connection to a PC on 
which the connection is terminated.

And though we don't want it, modems will turn up that do IPv6 NAT.

And what address do you think will be used as source address for 
connections originating from the CPE ? Like SIP ?

In all those cases, the WAN address is used for outgoing connections.
