If others still want to leave those points to other documents, | I'll obey that decision (but at least I want the "lifetime" document | to mention those a bit and to say that those are beyond the scope of | the doc). There's no question of ego here. The document is logically incomplete and meaningless if there's no discussion (either in the document, or in a companion) of what happens when a renewal attempt fails to achieve what was expected. It is all obvious what to do when a "renewal" info request gets back the same data as last time - even perhaps when it gives back that data, and more. It may even be fairly obvious (if not quite as obvious) what to do if there's no reply at all (dead dhcp server, or node moved to a location where there is no server). Dealing with replacement data (conceptually anyway) isn't hard to understand (in some cases it might be hard to implement) - ut dealing with getting an answer with some data missing is quite a different thing - it clearly isn't the same case as not getting an answer at all. Once again, the relevance of this to this doc is just that this doc is incomplete without that extra detail specified somewhere. It is however totally irrelevant what causes the new request to be made - whether it is the expiration of one timer or another, or the detection of some kind of "connected to a different link" signal, or even the (let's hope it is defunct) proposal where the server sent out messages to clients telling them to ignore previous timers and renew now. Because of this, having the specification in a different (referenced, and a normative ref at that) doc is an entirely reasonable thing to do. But moving forward with this "explicitly demand refresh" doc without any indication what should be done if it fails is simply not good enough. kre _______________________________________________ dhcwg mailing list dhcwg@ietf.org https://www1.ietf.org/mailman/listinfo/dhcwg
