I tried GRE with Neutron using RDO on 3 machines and got some warnings from the Firewall Team, that the installation is causing an ARP Flood in the network, does anybody know how to limit the ARP flood?

In my case, it was because openvswitch-switch was restarting because of a bug in a deployment script.

When you restart openvswitch-switch, you need to restart neutron-plugin-openvswitch-agent because the neutron agent configure the flows needed by openvswitch-switch

@cloudssky, are you still experiencing this problem? Do you have any data that you can share about this to perhaps see what's going on? I haven't been able to find other mentions of this problem that might help track down what's going on.
