There seems to be folks talking about very different environments, and in some cases attempting to make arguments which don't address the comments of the other side. I understand Nick's point. Coming freshly off a long sting at an ISP, I see the value (if it can be done in a sound technical manner), of having the * option * of a clean deployment for addressing and supplying IP related configuration information to the end host/router. This is not saying that it applies everywhere. It's quite obvious that in environments like sensor nets, home nets and other places, SLACC/RAs supply significant value. In other areas, like an operator access network (edge element addressing), it's a different case. Operators, such as the one I worked or, would never (rarely?) let an element auto-configure itself onto the network. I think there may be valid uses cases where, if feasible, there is perceived value is operating in DHCPv6 only mode. Of course, in many environments, DHCPv6 alone is not a good idea (example, my IPv6 light bulb) In the case of client functionality, in those highly controlled access network attachment areas, it is expected that the client (router or host) has a certain level of functionality (and often times this can be enforced). So it's reasonable to expect DHCPv6 client functionality in some use cases. > >There is a tiny amount of protocol glue missing which would allow dhcpv6 >to >act as a fully functional standalone protocol, and the various attempts to If this can be done, without harm to other environments, and achieve it's goals for those who want it (I.e operators who see a need and can articulate the benefits it will supply in network management and operation), I don't see why we are unwilling to discuss it's technical merits. >None of these points address the core issue which is that there are a lot >of operators who have a strong preference to use a single lan >configuration >protocol instead of two protocols with strongly overlapping functionality >and an ambiguous and poorly defined interaction model. I do wonder how many operators will ask for this? My concern is that if there are not too many raising their hands now, it may be that they either don't care, or if they are way behind in IPv6 deployment, they may not know that they care yet.
