It seems you don't want to use Play&Play of IPv6. In this case, you don't need to run rtadvd at all. It is a server for providing Plag&Play. > wvhemel> Anybody with a better understanding of routing, please enlighten me, or > wvhemel> point me to good resources... thanks :) > > Basically, if you use /etc/rc.conf, you can set something like: > > gif_interfaces="gif0" > gifconfig_gif0="real_ip tunnel_end_point" > ipv6_enable="YES" > ipv6_network_interfaces="ed1" > ipv6_prefix_ed1="3ffe:b80:1c8:1" > ipv6_gateway_enable="YES" > ipv6_router_enable="YES" > ipv6_router_flags="-A 3ffe:b80:1c8::/48,gif0 -O 3ffe:b80:1c8::/48,gif0" > rtadvd_enable="YES" > rtadvd_interfaces="ed1" wvhemel> This is what the script does, first I want to make everything work before wvhemel> I put it in my rc-files. I see. wvhemel> How would you go about if you would make a static route for each host? Yes, if you don't use Plag&Play of IPv6, you need to install static route to each host. wvhemel> That would be possible, no? Yes, you can with something like: route add -inet6 default link-local-address-of-router%interface-of-the-host When you use rc.conf, you can put something like: ipv6_defaultrouter="fe80::220:afff:fef8:7c44%de0" I you choose to use Plag&Play, default route will be installed automatically by invoking rtsol for end host. wvhemel> Allow me to explain what I want (if possible) and don't know how to wvhemel> achieve. I'd like to make the ip as short as possible, and appoint wvhemel> 3ffe:b80:1c8::1 to 192.168.196.1, 3ffe:b80:1c8::2 to 192.168.196.2, and so wvhemel> on. I understand your needs. wvhemel> Just to make sure, for the other machines, I just add something like wvhemel> '3ffe:b80:1c8::2' to ed1 with ifconfig? Yes, you can. However, you cannot use Plug&Play of IPv6 in this case. When you use rc.conf, you can put ipv6_ifconfig_* instead of ipv6_prefix_*. -- 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-questions" in the body of the message
