Re:Re: How to configure NM using dhclient-script file

[Mars <mars914 126 com>]

Hi Thomas,

Much thanks for your reply,  my problem is that NM cannot deal with the DHCPv6 message with IA_PD option, 

the default IA_NA option with NM cannot  generate the right prefixlen, just configuring 128 .

Best Regards
