How to configure another loopback device?

[John Dison]

Hello,



I want to configure lo1 loopback device and assign aliases to it via rc.conf system (at boot).I also want loopback addresses to remain on lo0.
What I have:ipv6_activate_all_interfaces="YES"ifconfig_lo1_alias0="inet IP4/32"ifconfig_lo1_alias1="inet6 IP6/128"cloned_interfaces="lo1"create_args_lo1="inet6 auto_linklocal"

As a result I have:
1) inet6 ::1 prefixlen 128   is configured on lo1 (I want it to stay at lo0)2) IP6 alias is missing from lo1 at all
I can achieve the desired configuration from command line, but I am unable to do the same via rc.conf. 
Any suggestions?
Thanks.
