confused about physnet

using packstack/centos7/mitaka

configured packstack like so:

CONFIG_NEUTRON_OVS_BRIDGE_MAPPINGS=**brex:br-ex**,br10:br-10,br15:br-15
CONFIG_NEUTRON_OVS_BRIDGE_IFACES=br-ex:em4,br-10:bond0.10,br-15:bond0.15
CONFIG_NEUTRON_OVS_BRIDGES_COMPUTE=br-10,br-15

Im confused about the CONFIG_NEUTRON_OVS_BRIDGE_MAPPINGS as the only place i find it is the openvswitch_agent.ini

/etc/neutron/plugins/ml2/openvswitch_agent.ini:bridge_mappings =brex:br-ex,br10:br-10,br15:br-15

so my question is....

If my physical interfaces are: bond0.10 (vlan 10) bridge br-10 bond0.15 (vlan 15) bridge br-15 em4 (flat network) bridge br-ex

what the hell is brex,br10 and br15? What should this be if not brex? In these next commands, what should --provider:physical_network=?:

confused about physnet

using packstack/centos7/mitaka

configured packstack like so:

CONFIG_NEUTRON_OVS_BRIDGE_MAPPINGS=**brex:br-ex**,br10:br-10,br15:br-15
CONFIG_NEUTRON_OVS_BRIDGE_IFACES=br-ex:em4,br-10:bond0.10,br-15:bond0.15
CONFIG_NEUTRON_OVS_BRIDGES_COMPUTE=br-10,br-15

Im confused about the CONFIG_NEUTRON_OVS_BRIDGE_MAPPINGS as the only place i find it is the openvswitch_agent.ini

/etc/neutron/plugins/ml2/openvswitch_agent.ini:bridge_mappings =brex:br-ex,br10:br-10,br15:br-15

so my question is....

is....

If my physical interfaces are:
bond0.10 (vlan 10) bridge br-10
bond0.15 (vlan 15) bridge br-15
br-15 
em4 (flat network) bridge br-ex

br-ex

what the hell is brex,br10 and br15? br15?

What should this be if not brex? brex?

And to follow all these questions, I have no idea how to move forward.....

In these next commands, what should --provider:physical_network=?:

should --provider:physical_network= command look like?
