Duplicate packet when ping to external with out floating ip

[KienHoang]

i build openstack yoga cluster: 3 node control, 2 node network, 2 node compute.
i create network and router success.
i create Instance and ping to external network
- when use floating ip: ok
- without floating ip: packer respond is duplicate ubuntu@msql:~$ ping 1.1.1.1

Hi KienHoang:

What ML2 mech driver are you using? What type of router do you have: legacy, DVR, HA, DVR+HA? What is the ping source and destination (port IPs, location, etc)?

Did you happen to track the ping in the VM TAP interface? Did you check the source MAC of the ping replies?

Regards.
