[rdo-list] [TripleO] Setting NeutronBridgeMappings just for compute nodes in NFV deployment

Hi, I would like to test my VNF on an openstack environment deployed using TripleO. For that I need to setup flat provider networks that go only to the compute node. I tried deploying an overcoud with additional neutron bridge mappings as following - Added NeutronBridgeMappings: " datacentre:br-ex,physdown;br-down,physup:br-up" to network environment file - Added following resources to compute.yaml file - type: ovs_bridge name: br-down mtu: 9000 members: - type: interface name: ens4f0 # force the MAC address of the bridge to this interface primary: true - type: ovs_bridge name: br-up mtu: 9000 members: - type: interface name: ens4f1 # force the MAC address of the bridge to this interface primary: true This will create the intended OVS bridges on the the compute node with the interfaces connected. The unwanted side effect it that ii also created the bridges on the controller node without any interfaces connected to it Is there a way to have the undercloud create the bridges only on the compute nodes and not on the controller nodes???
