I have an interface on which multiple vlans are connected. I would like to bridge the vlan 100 and 200 but also have a bridge for the "native" vlan 1. I Can setup a bridge for vlan 100 and 200 the way below I think but how to create a bridge for  the "native" vlan?

```
ETHER_IF=lagg0

ngctl -f- <<EOF
mkpeer ${ETHER_IF}: vlan lower downstream
name ${ETHER_IF}:lower vlan
connect ${ETHER_IF}: vlan: upper nomatch
EOF

ngctl mkpeer vlan: eiface vlan100 ether
ngctl msg vlan: addfilter '{ vlan=100 hook="vlan100" }'

ngctl mkpeer vlan: eiface vlan200 ether
ngctl msg vlan: addfilter '{ vlan=200 hook="vlan200" }'

ngctl -f- <<EOF
mkpeer vlan100: bridge lower link0
name bgp:lower vlan100bridge
connect vlan100: vlan100:lower upper link1
EOF

ngctl -f- <<EOF
mkpeer vlan10: bridge lower link0
name bgp:lower vla200bridge
connect vlan200: vlan200:lower upper link1
EOF
```
