(Just for easy tracking of this thread, I am slighly changing the subject) As I described in this draft, 3736 is definitely subset of 3315, thus, a host implementing 3315 can do both or either Stateful DHCPv6 for configuring the IPv6 address and Stateless DHCPv6 for the other information. Also M=1/O=0 can be invalid state based on admin policy. However, originally we tried to propose what scenarios with M/O flags were possible. It means that we did not enforce any specific scenario in this document because it can be easily done by admin policy. Thus, I (personally) would keep this combination in valid state.
Besides, as jinmei indicated earlier as editor of 2462bis, M flag (ON) indicated that the host (should) use the stateful protocol for address autoconfiguration. This should mean the M flag (ON) indicates Solicit/Advertise/Request/Reply. - Daniel (Soohong Daniel Park) - Mobile Platform Lab.
