This is how I use it on my router...  
These lines are in rc.conf, from a 9.0 box:
ifconfig_npe1="inet 192.168.x.x netmask 255.255.255.0"
vlans_npe1="12 13"
ifconfig_npe1_12="inet 10.y.y.y netmask 255.255.255.0"
ifconfig_npe1_13="inet z.z.z.z netmask 255.255.255.0"
ifconfig_npe1_13_alias0="inet z.z.z.z2 netmask 255.255.255.255"

Replace npe1 w/ the interface you are using..  And obviously replace
the ip's w/ the correct ones...  My internet connection is connected
to vlan 13 on npe1, and I have two ip addressess associated w/ that
interface...

I believe you can do "/etc/rc.d/netif start" if you don't want to
reboot, but I've never done that.. I've just rebooted, since this
is my router and I want to make sure it comes up...

Good luck...
