Dear all,

I try to establish a vxlan-connection between two VMs running under VMWare Fusion Pro 11.5 on Mac OS X 10.15.2

Both VMs (Debian 10) are connected in a host-only (user-defined) network and are able to ping each other. IPs 10.0.0.128/24 and 10.0.0.129/24

I have created a vxlan-connection between them via 
ovs-vsctl add-br br0
ovs-vsctl add-port vxlan0 — set interface vxlano type=vxlan options:remote_ip=10.0.0.128 options:key=1234
and vice versa
after this I brought all interfaces up and connected a Veth pair to both VMs like this. 
ip link add dev vmA1-sw type veth peer name vmA1
ip link set vmA1-sw up
ip link set vmA1 up
ip addr add 192.168.60.11/24 dev vmA1

and
ip link add dev vmA2-sw type veth peer name vmA2
ip link set vmA2-sw up
ip link set vmA2 up
ip addr add 192.168.60.12/24 dev vmA2

But at the end no ping between this new interfaces is possible, a tcpdump on br0 shows any relevant network packets (only some IPv6 ND packets)

Some more information:
The OVS-version is 2.10.1

            Interface "vxlan0"

                options: {key="1234", remote_ip="10.0.0.128"}
        Port "vmA1-sw"
            Interface "vmA1-sw"
    ovs_version: „2.10.1"

    Bridge "br0"
        Port "vxlan0"
            Interface "vxlan0"
                type: vxlan
                options: {key="1234", remote_ip="10.0.0.129"}
        Port "br0"
            Interface "br0"
                type: internal
        Port "vmA2"
            Interface "vmA2"
    ovs_version: "2.10.1"
root at west:~# 

How can I troubleshoot this connection or what should I do to establish a successful ping between the virtual interfaces 192.168.60.x?

best regards and merry Christmas
