>Description:
In /etc/rc.conf is documented the manual configuration for
IPv6:
#ipv6_ifconfig_ed0="fec0:0:0:5::1 prefixlen 64" # Sample alias entry
Unfortunately, this does not allow you to configure multiple
aliases, like the IPv4 code does. The code should also support
variables like:
#ipv6_ifconfig_ed0_alias0="fec0:0:0:5::2 prefixlen 64" # Sample alias entry
#ipv6_ifconfig_ed0_alias1="fec0:0:0:5::3 prefixlen 64" # Sample alias entry
And so on.
>How-To-Repeat:
Not really anything to repeat, now is there. :-)
>Fix:
Borrowing from the code that is in /etc/rc.network (v4) to
create a v6 example I recomend replacing this v6 code in /etc/rc.network6:
network6_interface_setup() {
[snip]
for i in $ipv6_network_interfaces; do
[snip]
eval ipv6_ifconfig=\$ipv6_ifconfig_$i
if [ -n "${ipv6_ifconfig}" ]; then
rtsol_available=no
rtsol_interface=no
ifconfig $i inet6 ${ipv6_ifconfig} alias
fi
With something more along these lines:
# Check to see if aliases need to be added
#
alias=0
while : ; do
eval ifconfig_args=\$ipv6_ifconfig_${ifn}_alias${alias}
if [ -n "${ifconfig_args}" ]; then
if [ -n "${ipv6_ifconfig}" ]; then
rtsol_available=no
rtsol_interface=no
ifconfig ${ifn} inet6 ${ifconfig_args} alias
alias=`expr ${alias} + 1`
fi
else
break;
fi
done
I'm not sure I'm doing the right things with the "rtsol_available"
and "rtsol_interface", or that there aren't other things that should be
done, so consider this an example only.
