Based on asking around about the "dropping duplicate flow:", it's a
known issue that is harmless (other than the noise). I'll try
to find out if someone has a fix in the works.

It seems your node1 has no port bindings... is that expected?

>From the counters, it looks like node2 and node3 have attempted
to send packets on the geneve tunnels, but neither has received
anything.

Could you verify that node2 and node3 have connectivity on the
IPs used for the tunnels, e.g. by trying to ping 172.10.10.75
and 172.10.10.73 from node2?

If that works, the issue might be iptables rules dropping
geneve packets, the simplest way around that would be to
"systemctl stop firewalld" if that's running (ok for a lab
environment anyway).

Thanks,
