hi, I did'nt knew your were trying linux-bridge , i just saw the error in l3-agent.ini. In case of linux bridge have you specified these two parameters in l3-agent.ini
*Linux Bridge* interface_driver ($NEUTRON_CONF_DIR/l3_agent.ini) neutron.agent.linux.interface.BridgeInterfaceDriver external_network_bridge ($NEUTRON_CONF_DIR/l3_agent.ini) This field must be empty (or the bridge name for the external network). Can you paste your conf files of quantum.
