[ipv6-wg] [Snac] [v6ops] "router cascade with DHCPv6-PD"

(Hi Martin, I'm just the messenger, your questions are all pretty good.  For
others, I think it was not obvious that they are about draft-winters-v6ops-cpe-lan-pd-00.
But, more than my brain can handle right now)

I think that actually we've created an ambiguity about whether they are
DHCPv6 relays or if they are full DHCPv6 servers.
There are arguments both ways, and in some cases the choice is transparent to
the end system, but in other ways it is not.

The lack of a standardized way to communicate DHCPv6-server PD to
DHCPv6-relay, and the expectation that the relay would just *snoop* on the
DHCPv6-PD contents has bugged me for a long time.  If we are going to
recommend that they act as relays, then I'd like to fix that.

Either way, Tim's v6ops draft-winters-v6ops-cpe-lan-pd-00 should clarify.
LPD-1 suggests the IPv6 CE Router is a server, not a relay.
