I forgot to mention where this is explicitly stated. In TIA-835-C, Section 3.2.1.4.2 "IPv6 Addressing":
--->BEGIN For an IPv6 MS, the PDSN shall be the default router and the PPP termination point. The PDSN shall allocate one globally unique /64 prefix to each PPP link. The PDSN shall not construct any global address from this prefix. --->END - Pete -----Original Message----- From: Barany, Pete Sent: Thursday, February 12, 2004 7:46 AM To: 'Pekka Savola' Cc: Karim El-Malki (HF/EAB); [EMAIL PROTECTED] Subject: RE: updates to IPv6 over PPP spec. The PDSN in cdma2000 does not have a global unicast address for the PPP connection between itself and the mobile. It only has a link-local address. The mobile has both a link-local and global unicast address.

In fact, quite the contrary. Umm.. but doesn't the access router which terminates the PPP link also have an address from that /64 prefix (e.g., ::1) -- or does it have a link-local address only? In case such an assumption is made, it should be spelled out clearly enough. -- Pekka Savola "You each name yourselves king, yet the Netcore Oy kingdom bleeds." Systems. Networks.
