[ovs-discuss] Bridge traffic stops flowing after ovs-vtep run

Hi. I'm trying to implement the VTEP Emulator from
https://github.com/openvswitch/ovs/blob/master/vtep/README.ovs-vtep.md
I've built OVS from source on Centos7, trying to interconnect docker
containers between different and within a single docker node. Still no
traffic flows between containers.

I have:
[root at ovs11 ovs]# vtep-ctl list-remote-macs ls0
ucast-mac-remote
  7a:2c:ba:c0:62:16 -> vxlan_over_ipv4/10.2.2.102
  c2:fd:9f:ea:3f:e3 -> vxlan_over_ipv4/10.2.2.101
  de:eb:3c:62:65:fc -> vxlan_over_ipv4/10.2.2.103
a mac to ip mapping table populated on each host.
[root at ovs11 ovs]# ovs-vsctl show
82434185-c196-45dd-bcf1-1260e33ceae3
    Bridge vtep_bfd
        Port "bfd10.2.2.101"
            Interface "bfd10.2.2.101"
                type: vxlan
                options: {remote_ip="10.2.2.101"}
        Port "bfd10.2.2.102"
            Interface "bfd10.2.2.102"
                type: vxlan
                options: {remote_ip="10.2.2.102"}
        Port "bfd10.2.2.103"
            Interface "bfd10.2.2.103"
                type: vxlan
                options: {remote_ip="10.2.2.103"}
        Port vtep_bfd
            Interface vtep_bfd
                type: internal
    Bridge "vtep_ls1"
        Port "vx2"
            Interface "vx2"
                type: vxlan
                options: {key="0", remote_ip="10.2.2.102"}
        Port "vx1"
            Interface "vx1"
                type: vxlan
                options: {key="0", remote_ip="10.2.2.101"}
        Port "0000-p0-l"
            Interface "0000-p0-l"
                type: patch
                options: {peer="0000-p0-p"}
        Port "vx3"
            Interface "vx3"
                type: vxlan
                options: {key="0", remote_ip="10.2.2.103"}
        Port "vtep_ls1"
            Interface "vtep_ls1"
                type: internal
    Bridge "br0"
        Port "p1"
            Interface "p1"
        Port "br0"
            Interface "br0"
                type: internal
        Port "0000-p0-p"
            Interface "0000-p0-p"
                type: patch
                options: {peer="0000-p0-l"}
        Port "1d53fed7f9284_l"
            Interface "1d53fed7f9284_l"
        Port "p0"
            Interface "p0"

Port "1d53fed7f9284_l" is a docker container's port.
Settings look fine, but still no traffic flows. Thanks in advance.
