Ya I know about them. I have LAN behind the host that working just fine 
using 10.0.0.0/8

I get my dynamic ip address from my ISP this way.
ifconfig_re0="DHCP"

Now to create vlan for re0 I have this in rc.conf

vlans_re0="1 2 3"

ifconfig=re0__1="DHCP"  times out with no address from the isp during boot
ifconfig=re0__1="inet 10.0.500.1/24"  gets invalid ip address in boot log.

My understanding of vlans is the first vlan tag steps on any ip address 
the parent re0 has gotten by DHCP. That is why I tried 
ifconfig=re0__1="inet 10.0.500.1/24"

What is wrong here?
