</span>The standard configuration for vlan network applies. The setup I've<br>
describe does not use an external router, so you will not pass through<br>
the network node and will not use br-ex bridge.<br>
<br>
I'm using ml2 with openvswitch, so the relevant options for ml2_conf.ini are:<br>
<br>
[ml2]<br>
type_drivers = gre,vlan,vxlan<br>
mechanism_drivers = openvswitch<br>
<br>
[ml2_type_vlan]<br>
network_vlan_ranges = vlannet:1:4000<br>
<br>
[ovs]<br>
bridge_mappings = vlannet:br-vlan<br>
<br>
br-vlan is an openvswitch bridge created on the compute node with:<br>
<br>
ovs-vsctl -- --may-exist add-br br-vlan<br>
ovs-vsctl -- --may-exist add-port br-vlan bond0<br>
<br>
in my case, bond0 is an interface on the compute node in "trunk", so<br>
that packets are received with the vlan tag on the node.<br>
