requiring that a /64 is unique on a link does not avoid DAD. doesn't the 3GPP specs restrict one end of the link to not use any addresses from the prefix, if so DAD is not needed. > Since the IETF IPv6 WG is in the process of updating the IPv6 PPP RFC 2472 > (more specifically IPV6CP), my question is: What changes are being planned > to that RFC?

Thanks. the only thing I can see requiring an update is that the value of DupAddrDetectTransmits should default to 1 not 0. you can turn off DAD in your environment if you know you don't need it. /ot -------------------------------------------------------------------- IETF IPng Working Group Mailing List IPng Home Page: http://playground.sun.com/ipng FTP archive: ftp://playground.sun.com/pub/ipng Direct all administrative requests to [EMAIL PROTECTED] --------------------------------------------------------------------
