	Ok, it was actually obvious :

# ./ovs-vsctl show
4878360b-97f7-4ed0-97a8-0d9d284257fe
    Bridge "br8"
        Controller "ptcp:6634"
        Controller "tcp:127.0.0.1:6633"
        fail_mode: secure
        Port "br8"
            Interface "br8"
                type: internal
        Port "vx2"
            Interface "vx2"
                type: vxlan
                options: {key="1", remote_ip="10.0.8.3"}
    Bridge "br9"
        Controller "tcp:127.0.0.1:6635"
        Controller "ptcp:6636"
        fail_mode: secure
        Port "vx4"
            Interface "vx4"
                type: vxlan
                options: {key="2", remote_ip="10.0.8.3"}
        Port "br9"
            Interface "br9"
                type: internal

	Have fun...
