Is there any way to create, and assign addresses to a if_vlan

I'll post back with the results in case anyone else here has been
interested in 'Cisco style' (as I for some reason refer to them as)
sub-ints on FreeBSD.
# cat /etc/rc.conf (snipped for brevity)
cloned_interfaces="em6.7"
ifconfig_em6_7="inet6 2607:f118:ddc0:8000::e19"
# reboot
# ifconfig (again, snipped for brevity)
em6: flags=8802<BROADCAST,SIMPLEX,MULTICAST> mtu 1500
options=b<RXCSUM,TXCSUM,VLAN_MTU>
ether 00:60:e0:42:b1:7c
media: Ethernet autoselect (1000baseTX <full-duplex>)
status: active
em6.7: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
inet6 2607:f118:ddc0:8000::e19 prefixlen 64
ether 00:60:e0:42:b1:7c
media: Ethernet autoselect (1000baseTX <full-duplex>)
status: active
vlan: 7 parent interface: em6

Now, my next question is, can I have interface em6.7 operate on multiple
vlans? ie, change the default behavior of the if_vlan interface's
implicit designation to only vlan 7?
I want to have multiple prefixes (ie: subnets) within a single broadcast
domain, but each prefix on its own sub-interface on the FreeBSD box,
without designating a VLAN for each. (Please forgive the IPv6 test
above, as it probably misguides my efforts... my tests at this point are
purely to *hopefully* meet an IPv4 conceptual design goal).
Is this possible?
Steve
