CPE router learning DNS servers - comment on draft-ietf-v6ops-ipv6-cpe-router-03
1. I noticed draft-ietf-v6ops-ipv6-cpe-router does not reference RFC5505,
"Principles of Internet Host Configuration". Is that intentional?
2. http://tools.ietf.org/html/rfc5505#page-11 says, in part:
In IPv6, where link-layer-independent mechanisms such as stateless
autoconfiguration [RFC4862] and stateless DHCPv6 [RFC3736] are
available, PPP IPv6CP [RFC5072] configures an Interface-Identifier
that is similar to a Media Access Control (MAC) address. This
enables PPP IPv6CP to avoid duplicating DHCPv6 functionality.
and I see that draft-ietf-v6ops-ipv6-cpe-router-03 only says:
L-6: The IPv6 CE router MUST support a DHCP server [RFC3315] on its
LAN interfaces. It MAY support Stateless Dynamic Host
Configuration Protocol (DHCP) Service for IPv6 [RFC3736].
Why is that only a MAY? I mean, without the CE doing DHCPv6 towards
the Service Provider's network, is there some other way the CE router
learns the IPv6 network's DNS servers so it can propagate those
DNS servers to hosts connecting to the CE router? (I hope the answer
is not 'manual configuration').
