The process we used to create our vLAN interfaces:
  ifconfig bge0 up
  ifconfig vlan100 create
  ifconfig vlan100 inet 10.0.0.1/24 vlan 100 vlandev bge0

The first line brings the parent interface up and establishes the 
connection to the switch.

The second line create the vlan100 interface.  The number can be anything 
you want, so long as it is unique for all vlan interfaces.

The third line configures the IP on the vlan100 interface, sets the vlan 
number (to tag the packets with) and associates it with the parent 
interface.

Any packets you route through vlan100 will have the vlan 100 tag 
added/removed as needed.

The lines needed in /etc/rc.conf to automate this are:
  cloned_interfaces="vlan100"
  ifconfig_bge0="up"
  ifconfig_vlan100="inet 10.0.0.1/24 vlan 100 vlandev bge0"

See the ifconfig(8) and rc.conf(5) man pages, and the comments 
in /etc/defaults/rc.conf for more info.
