-------------------- Marcelo Bagnulo (2005-10-12): https://www.machshav.com/pipermail/mobike/2005-October/001117.html 11. In section 4.5. the NO_ADDITIONAL_ADDRESSES notification is presented. As i understand it, this is the only way to delete addresses from the address set, right? This is kind of twisted, i think. I mean, if a node wants to delete one address because is no longer available it, must: - delete all the addresses using a NO_ADDITIONAL_ADDRESSES notification message - add other addresses with a ADDITIONAL_ADDRESSES notification is this so? If yes, i think this should be clearly stated imho (at least that the NO_ADDITIONAL_ADDRESSES notification serves to delete addresses) -------------------- Tero Kivinen (2005-10-12): https://www.machshav.com/pipermail/mobike/2005-October/001116.html 3) I think that section 4.5 should clarify you use either ADDITIONAL_*_ADDRESSES or NO_ADDITIONAL_ADDRESSES, not both (but you always have either exactly one NO_ADDITIONAL_ADDRESSES or one or more ADDITIONAL_*_ADDRESSES), and also explain more when to use NO_ADDITIONAL_ADDRESSES. The actual usage of the NO_ADDITIONAL_ADDRESSES is not really explained anywhere (though it is quite obvious from the name if people understand that the ADDITIONAL_*_ADDRESSES are only used for the ADDITIONAL addresses beside the ones in the IP header of the exchange packet). Actually, I think even that text is missing, i.e. text saying that the ADDITIONAL_*_ADDRESSES are used in addition to the IP address of the current exchange packet. -------------------- Tero Kivinen (2005-10-13): https://www.machshav.com/pipermail/mobike/2005-October/001118.html No, I have not understood that section that way. I assumed that the new list of addresses (ADDITIONAL_ADDRESSES) always overwrites the whole previous list. I.e. it is not incremental update, but it is full list every time. In some cases where you have only one IP-address, the ADDITIONAL_ADDRESSES notify would not be there, and you need to have some way to tell that there is no other addresses than the one that is used in the IP-headers of this packet. -------------------- Marcelo Bagnulo (2005-10-15): https://www.machshav.com/pipermail/mobike/2005-October/001118.html ok, i think we have identified an important element here: my reading of this was that additional addresses are incremental to the set already available. I think that it would be very important to explictly state whether the addresses in the additional address is a complete set or an incremental update. -------------------- Francis Dupont (2005-10-16): https://www.machshav.com/pipermail/mobike/2005-October/001120.html - in 4.5 page 14 As described in Section 4.3, both the initiator and responder can send a list of additional addresses in the IKE_AUTH exchange. This information can be updated by sending an INFORMATIONAL exchange request message that contains either one or more ADDITIONAL_IP4/ 6_ADDRESS notifications or the NO_ADDITIONAL_ADDRESSES notification. => there is no explanation about NO_ADDITIONAL_ADDRESSES: 4.3 can't help because it doesn't use it. I propose to move or copy some text from 5.3 where the notification is described. - in 5.3 page 18 The NO_ADDITIONAL_ADDRESSES notification can be included in an INFORMATIONAL exchange request message to indicate that the exchange initiator does not have addresses beyond the one used in the exchange (see Section 4.5 for more detailed description). => in fact in the *current* document there is no description at all of NO_ADDITIONAL_ADDRESSES... -------------------- Tero Kivinen (2005-10-17): https://www.machshav.com/pipermail/mobike/2005-October/001121.html > ok, i think we have identified an important element here: my reading of > this was that additional addresses are incremental to the set already > available. > > I think that it would be very important to explictly state whether the > addresses in the additional address is a complete set or an incremental > update. Agree on that. (and it is complete set). -------------------- Stephane Beaulieu (2005-10-17): https://www.machshav.com/pipermail/mobike/2005-October/001127.html Section 3.2 - Is there a way to remove an address? (ex. Pull out my wireless adapter). Tero mentioned in another thread that he assumed that sending a new ADDITIONAL_X_ADDRESS notify overwrote all past addresses, but this isn't clear to me from the text. -------------------- Jari Arkko (2005-10-19) https://www.machshav.com/pipermail/mobike/2005-October/001135.html The consensus seems to be that the text in question needs to be clarified to say that the new list overwrites the old. (Note: I think we decided a long time ago that we're not doing incremental updates but rather entire new lists. We're not reopening that discussion. However, our reviewers indicate that the text isn't clear.) --------------------
