Dual stack with multiple addresses in rc.conf

[Steve Bertrand]

Hi all,

I'm having a difficult time sorting out how to have all my required IP 
addresses (and gateways) configured correctly on boot up via rc.conf.

I've tried all manner of methods using aliases etc, but somehow or 
another, the machine fails to configure all of the addresses correctly, 
and it never configures the IPv6 defaultrouter in the routing table. I 
must stand by the console of the machine if it needs to be rebooted so I 
can manually configure the addresses/routes that do not set themselves 
up correctly.

Can someone please advise me on the proper configuration as it should be 
in rc.conf for the following addresses? All of the addresses need to be 
configured on a single interface (fxp0):

ifconfig_fxp0="inet6 2607:f118::b6 prefixlen 64"
ifconfig_fxp0_alias0="inet6 2607:f118::b7 prefixlen 64"
ifconfig_fxp0="inet 208.70.104.210 255.255.255.248"
ifconfig_fxp0_alias1="inet 208.70.104.211 netmask 255.255.255.255"

defaultrouter="208.70.104.209"
ipv6_defaultrouter="2607:f118::1"

Regards,

Steve
