I agree with the basic idea of this RFC. I tested it on my box. When default interface is set to actuall network interface, it takes a while to falldown to use IPv4. Is it reasonable for you? oberman> This is certainly reasonable, too.

Selecting lo0 is a problem in rc.network6. Since you are using a laptop, there is no suitable network interface at boot. Then, rc.network6 choose lo0 wrongly as default interface. It may better to avoid choosing lo0 in rc.network6. I'll commit it. But, it is workaround after all. -- Hajimu UMEMOTO @ Internet Mutual Aid Society Yokohama, Japan ume@mahoroba.org ume@bisd.hitachi.co.jp ume@{,jp.}FreeBSD.org http://www.imasy.org/~ume/ To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-net" in the body of the message
