hi, I'm configuring vlan with bonding in my openstack networking setup. All servers are running Ubuntu 14.04 (1 network, 1 controller, 4 compute nodes, 4 swift nodes) Thus I have the mgmt-, tunnel-, and external network as vlans: bond0.45, bond0.46 and bond0.47

I'm currently configuring the network node, configuring file: /etc/neutron/plugins/ml2/ml2_conf.ini the ovs [ovs] local_ip = ip of bond0.46 enable_tunneling = True bridge_mappings = external:br-ex

I'm newbie, so I'm not sure yet about the definition: external:br-ex what is the meaning of this parameter? How can I relate this to my bond0 and vlan definitions? Thanks Yngvi

Can you see br-ex when you run ip or ifconfig command?. If not create it by running

$ovs-vsctl add-br br-ex

Please follow this guide.

Thanks for the feedback ;-) This is the general manual I've been reading. I'm also trying to find out how my 'bond0' and vlan parameter fit into these definitions.... The notification must refer to those configurations, right?
