Hi,
I may have done something really stupid here but if I have I can not see what
it is. Basically I have some configuration in rc.conf to set up a gif tunnel
for ipv6. I have used the same config I used to use on 5.0-RELEASE a few
months ago but I removed that config when the tunnel broker I was using went
out of business.
I have been tracking -CURRENT since but only this morning decided to set up a
new tunnel broker service. I placed the same config back in rc.conf to set
this up, changed the relevant ip address's for the new broker and rebooted
after my latest cvsup/buildworld.
What happened was that the lan interface (xl1) got configured with link-local
and site-local and rtadvd was started. This all worked perfectly. However the
gif tunnel only managed to configure the inet4 tunnel part of the
configuration and was missing the inet6. This caused further errors during
boot as the default route was attempted to be set.
The relevant parts of rc.conf look like this:
ipv6_enable="YES"
ipv6_network_interfaces="xl1 lo0"
ipv6_ifconfig_xl1="fec0:0:0:1::1 prefixlen 64"
gif_interfaces="gif0"
gifconfig_gif0="62.30.69.139 64.71.128.82"
ipv6_ifconfig_gif0="2001:470:1F00:FFFF::32F 2001:470:1F00:FFFF::32E prefixlen
128"
ipv6_defaultrouter="2001:470:1F00:FFFF::32E"
ipv6_ifconfig_xl1_alias0="2001:470:1F00:507::1 prefixlen 64"
ipv6_gateway_enable="YES"
rtadvd_enable="YES"
rtadvd_interfaces="xl1"
xl0 is my internet connection, xl1 is my lan connection, and gif0 is the
tunnel.
After booting the system ifconfig gif0 looks like this:
gif0: flags=8050<POINTOPOINT,RUNNING,MULTICAST> mtu 1280
tunnel inet 62.30.69.139 --> 64.71.128.82
There is no inet6 part and the default route for inet6 has not been set.
If I manually then add the configuration I specified in rc.conf it works fine:
[root@tao root]# ifconfig gif0 inet6 2001:470:1F00:FFFF::32F
2001:470:1F00:FFFF::32E prefixlen 128
[root@tao root]# route add -inet6 default 2001:470:1F00:FFFF::32E
add net default: gateway 2001:470:1F00:FFFF::32E
[root@tao root]# ifconfig gif0
gif0: flags=8051<UP,POINTOPOINT,RUNNING,MULTICAST> mtu 1280
tunnel inet 62.30.69.139 --> 64.71.128.82
inet6 2001:470:1f00:ffff::32f --> 2001:470:1f00:ffff::32e prefixlen
128
inet6 fe80::2a0:24ff:feac:e1b4%gif0 prefixlen 64 scopeid 0x4
So my question is have I done the rc.conf configuration incorrectly or is
there something wrong with the rc scripts that start inet6?
