Hi, 

You are running a (very) old version of my guide. 

Try to read it again or follow official documentation available.

Hi Dan, 
I am following Folsom Installation guide provided by Emilien Macchi. In that document it is mentioned to create a bridge 'br-int' attached to 'eth1' through ovs. And also it suggests to assign this ' br-int ' bridge as ' integration_bridge ' and ' br-eth1 ' as ' bridge_mappings ' in '/etc/quantum/plugins/openvswitch/ovs_quantum_plugin.ini' like the following: 



integration_bridge = br-int 
bridge_mappings = default:br-eth1 


Please clarify me, is it necessary to enable 'bridge_mappings' field. 


Regards, 
Srikanth.

It sounds like your config file is saying that you have an OVS bridge 
named "br-eth1", but it looks like you do not. 

Did you intend to do this, or is this a config copied from somewhere else? 

If you actually intended to use VLANs that send traffic out eth1, you 
can do the following: 

# create bridge 
ovs-vsctl add-br br-eth1 

# add eth1 as a port on this bridge 
ovs-vsctl add-port br-eth1 eth1
