I have 3 network nodes running neutron-server ..

Only one of these nodes is attached to the external network

I use ml2 with openvswitch

in the bridge mapping of the node connected to the external network , i have external_net mapped to the correct bridge ..

On the other nodes i do not have this mapping defined and i do not have interfaces

The issue i have is the following

When i try to start a virtual machine that is connected to the external network , i have this error in the logs :

on both nodes( node002 and node003 ) , because they DO NOT have this network defined ! so is this a bug or such a setup is not valid ?
