Yes, as far as I can see

> Also, when you create the vlan interface, what options do you use to
create it ?

bash-2.05b# grep vlan0 /etc/rc.conf
cloned_interfaces="vlan0 vlan1 vlan2 vlan3 vlan4 vlan5 gif0"
ifconfig_vlan0="inet 10.9.8.186 netmask 0xfffffffc vlan 850 vlandev em0 mtu
1500"
bash-2.05b#
