>Description:
My FreeBSD box has a "IPv4 over IPv6" tunnel.
It was configured in 5.4-RELEASE by rc.conf shown below:
gif_interfaces="YES"
gif_interfaces="gif0"
gifconfig_gif0="2001:DB8:0001::1 2001:DB8:0001::2"
ifconfig_gif0="inet 192.0.2.1 netmask 0xffffffff 192.0.2.2"
But it does not work in 6.1-RELEASE.
It seemes to be caused by a difference of /sbin/ifconfig.
>How-To-Repeat:
'ifconfig gif0 tunnel 2001:DB8:0001::1 2001:DB8:0001::2'
works in FreeBSD 5.4.
The command does not work in FreeBSD 6.1 with error:
`ifconfig: SIOCSIFPHYADDR: Address family not supported by protocol family`
>Fix:
Now I'm using a local script shown below,
but I think /etc/network.subr should be revised.
