Public bug reported:

I have strange issue. VXLan fails to connect dhcp agent and compute
node. VXLan compute-compute builds successfully. No log ERROR or even
WARNING.

compute node:

 Bridge br-tun
        fail_mode: secure
        Port br-tun
            Interface br-tun

            Interface "vxlan-c0a86424"
                type: vxlan
                options: {df_default="true", in_key=flow, local_ip="192.168.100.29", out_key=flow, remote_ip="192.168.100.36"}
        Port patch-int
            Interface patch-int

        Port "vxlan-c0a86424"

                type: vxlan

        Port br-tun
            Interface br-tun
                type: internal


I have 2 vms, at compute .36 and .29. As you can see, compute doesn't have tunnel exit from dhcp agent node.
This was deployed by latest master kolla, which translates to latest master neutron.
