ipv6_ variables in /etc/rc.conf is not affected

[Koichi MATSUMOTO]

Hi,

I have installed DragonFly 5.0.2 on my VPS, and add the following lines to /etc/rc.conf, then reboot:

ipv6_enable="YES"
ipv6_network_interfaces="vtnet0"
ipv6_ifconfig_vtnet0="inet6 2001:470:d:461::7:1"
ipv6_defaultrouter="2001:470:d:461::1”

However, the ipv6 address is not assigned a network interface, and also not assigned default gateway.
What else should I do?
