Hi:

This is to confirm on the DHC WG mailing list our proposal to resolve the RFC3315bis Ticket #152 (RA with prefix lifetime of 0) by updating RFC3315bis as follows (see http://trac.tools.ietf.org/group/dhcpv6bis/ticket/152 and https://www.ietf.org/proceedings/94/slides/slides-94-dhc-5.pdf for more details):

*       A DHCPv6 client SHOULD send a DHCPv6 Renew for a DHCPv6 assigned address if a Router Advertisement is received with a PIO for a prefix with a lifetime of 0 (and the address is contained in the prefix).
*       This covers the case when the DHCPv6 Server that gave out the address has released the Delegated pool back to the Server
-      According to Ticket #151<http://trac.tools.ietf.org/group/dhcpv6bis/ticket/151>, the Request Router should transmit RAs with a lifetime of 0
-      Triggering a DHCPv6 Renew will make sure the address is still valid or new one may be assigned

If you want to comment on this (or ask for clarification), please respond by 11/23. The RFC3315bis team will otherwise update the draft as per the above.

Thanks.


-          Bernie
