"Section 4.1 WAN side configuration
WLL-1: The IPv6 CE router MUST support IPv6 over Ethernet [RFC2464]."
I don't see how that can be a MUST when the WAN interface may not
support Ethernet framing e.g. a 3G/HSPDA or Wimax IPv6 CS WAN interface.
Similarly for the PPPoE requirement (and arguably for the PPP
requirement) -
"WLL-2: The IPv6 CE router MUST support IPv6 over PPP [RFC5072] and
PPPoE [RFC2516]. In a dual-stack environment with IPCP and
IPV6CP running over one PPP logical channel, the NCPs MUST be
treated as independent of each other and start and terminate
independently."
I think it would be better to try to avoid making anything relating to
IPv6-over-foo support MUSTs, keeping the scope to IPv6 CPE
requirements. If IPv6-over-foo functions are in scope for the draft,
then I'd suggest making treating them as separate sections, saying
something like, "If the WAN interface supports Ethernet encapsulation,
then it MUST support IPv6 over Ethernet [RFC2464] and PPP [RFC5072]
and PPPoE [RFC2516].", "If the WAN interface supports ATM encapsulation,
then it MUST support PPPoA [RFCXXXX]" etc.
A future CPE's lack of compliance with this draft just because it
doesn't support Ethernet framing on it's WAN interface would be a shame.

Mark.
