Open Stack

Thanks a lot Andreas ;-)
OK, so I would configure the br-ex as usually,

auto br-ex
iface br-ex inet static
        address a.b.c.d
        netmask 255.255.255.0
        network a.b.c.0
        dns-nameservers x.x.x.x
        dns-search domin.xx
        gateway a.b.c.1

but is it valid to configure the  vlan bond0.45   like this, thus in promisc mode ?

auto bond0.45
iface bond0.45 inet manual
up ifconfig $IFACE 0.0.0.0 up
up ip link set $IFACE promisc on
down ip link set $IFACE promisc off
down ifconfig $IFACE down


best regards
Yngvi

Your setup should be fine.

Ensure, that you have created your openstack external network as flat provider network (default with devstack). Then adding br-ex into the vlan device enforces vlan traffic on the external network. 
An alternative approach would be to add the bond interface into the br-ex (instead of its vlan device) and create your openstack external provider network as vlan network using vlan 45.
Both should work!

In general take be aware, all the vlans you're using have to be enabled in your hardware switch as well if it's not a 20$ device.
