There's no need to require an address for IPv6 interfaces in general. All I would like to see is recognizing 'ipv6_ifconfig_<interface>="NOAUTO"', which certainly parallels the IPv4 situation. > In many ways I think the best thing to do is remove plip from GENERIC > and be done with it. > > -- Brooks I've discovered I omitted an important precondition to my bug: it requires ipv6_gateway_enable to be set to YES. So, here is the true set of circumstances which leads to the problem: ipv6_enable="YES" ipv6_gateway_enable="YES" GENERIC kernel Removing plip from GENERIC would definitely solve this problem. -- George Mitchell P.S. Speaking of IPv6 networking, could someone take a quick look at bug 102701, with my patch for an IPv6 ifconfig problem?
