OVS sintaxys is pretty much the same ( as brctl ) but it was a pain to write
all the configs for mine situation - actualy its default case when you
creating advanced zone with GRE isolation in cloudstack ( but ovs and
cloudstack manuals are realy poor)
About fake bridges :
For compatibility with software designed for the Linux bridge,
ovs-vsctl also supports a model in which traffic associated with a
given 802.1Q VLAN is segregated into a separate bridge. A special form
of the add-br command (see below) creates a ``fake bridge'' within an
Open vSwitch bridge to simulate this behavior. When such a ``fake
bridge'' is active, ovs-vsctl will treat it much like a bridge separate
from its ``parent bridge,'' but the actual implementation in Open
vSwitch uses only a single bridge, with ports on the fake bridge
assigned the implicit VLAN of the fake bridge of which they are mem‐
bers. (A fake bridge for VLAN 0 receives packets that have no 802.1Q
tag or a tag with VLAN 0.)
I know that everything else is working as it should and I dont want to
create this Tunnel manually - no point. I think ill open a bug
Thanks
