As I wrote below, these drafts did not pass wglc. Most members of the wg did not respond to the last call. Some of those who responded had technical objections to agentopt-delegate. We now need to find out what to do next. Do people believe that we don't need this, do you believe that snooping is a fine alternative? Or do you believe it can be done in some other way? The main issue is how to inject the necessary routes into the routing system. From a routing point of view it would be reasonable to have the route announced by the router that requested and was assigned the prefix. However this router would often be a customer router where the ISP router would not accept such route advertisements unless it knows they are legitimate. If the ISP router does not know what prefixes the customer has been assigned, some form of authentication would be needed. I don't know if that exists and it sounds complicated. agentopt-delegate would allow the ISP router to know what prefixes to allow routes for, or to announce routes for those itself. Another theoretical possibility would be for the DHCP server to somehow inject the route itself on behalf of the customer. I believe this is generally not possible, and does not sounds like a particularly nice solution. In short, what I would like to ask is, what is the alternative solution, or don't we need one? Or can the agentopt-delegate solution be improved in some way? I would like to get some discussion on this so that we can determine where to go next with these drafts.
