Vijay: Correct - we don't have T1/T2 times for IA_TA. It is the clients choice as to when (and if) to renew these. I would think it would following a policy similar to that specified in RFC 3041 (to extend the preferred and/or valid lifetime). Essentially, the client should start the renewal process early enough to continue using the address. I don't think the DHCP server needs to follow the procedures of RFC 3041 in generating temporary addresses. The DHCP server may not even have the client's link-local address (interface identifier). >Probabably, we can add some text to state that once a temporary >address is released or lifetime expires, the server should >forget the bindings, unlike the normal addresses. For temporary addresses, there is good reason for the server to forget them as ever being associated with a client after the valid lifetime expires (or it is released). However, this may also be the case for normal addresses. For normal addresses, this is really a server policy issue and up to the server (or administrator of the server if configuration of this is allowed). - Bernie -----Original Message----- From: Vijayabhaskar A K [mailto:vijayak@india.hp.com] Sent: Saturday, June 15, 2002 10:06 AM To: dhcwg@ietf.org Subject: [dhcwg] Temporary addresses We dont have T1 and T2 values for IA having temporary addreses but the draft says that the temporary addresses can be renewed. So, if the client wishes to renew the adddresses, when should the client renew the addresses? Does it mean that the application has to trigger the renew in the case, if it need to use the address for some more time? RFC 3041 says the mechanism of generating random Interface IDs, for subsequent addresses for the same interface of the node. Does the DHCP server need to implement this mechanism for allocating temporary addresses to the client? Probabably, we can add some text to state that once a temporary address is released or lifetime expires, the server should forget the bindings, unlike the normal addresses. This will be helpful in allocating different addresses for the subsequent request from the same node.
