Hi,

I want to add bridge mapping to the compute nodes so that I can add provider networks to it.
I tried the following but that created the bridges also on the controller nodes

NeutronBridgeMappings: "datacentre:br-ex,physctrldown;br-ctrldown,physctrlup:br-ctrlup,physdatadown:br-datadown,physdataup:br-dataup"
NeutronFlatNetworks: "datacentre,physctrldown,physctrlup,physdatadown,physdataup"

I then tried the following but that caused an error during deployment

NeutronBridgeMappings: "datacentre:br-ex"
NeutronFlatNetworks: "datacentre,physctrldown,physctrlup,physdatadown,physdataup"
NovaComputeExtraConfig:
    neutron::agents::ml2::ovs::bridge_mappings: "datacentre:br-ex,physctrldown;br-ctrldown,physctrlup:br-ctrlup,physdatadown:br-datadown,physdataup:br-dataup"

ERROR was

How can I have the bridges created only on the computes nodes??
