Hi John,
>I think a possible resolution to this is to state something like the >following: > > 2.5.1 Stateless Address Autoconfiguration in 3GPP > > A 3GPP cellular host must process a Router Advertisement as stated > in chapter 5.5.3 of [RFC-2462]. > > These cellular hosts can set DupAddrDetectTransmits equal to zero, > as each delegated prefix is unique within its scope when allocated > using the 3GPP IPv6 Stateless Address Autoconfiguration. > > See appendix B for more details on 3GPP IPv6 Stateless Address > Autoconfiguration. > It seems reasonable, and consistent with RFC2462 and the PPP for IPv6 spec, to avoid DAD for addresses where the remote side (GGSN) assigns the IID. I am less certain about the privacy address case. Privacy addresses post-date the PPP spec, so it does not deal with them... In fact, we know that the PPP spec will need to be updated, eventually, to match the newest addressing architecture. Do the 3GPP specifications explicitly state that the GGSN must not allocate any addresses within the allocated prefix? If so, in which document?
