Hi Georgios,
Based on the code (
https://github.com/openstack/nova/blob/3658e1015a2f7cb7c321cc1a0adfda37757fd80b/nova/network/linux_net.py#L754)
it looks like the command that Nova executes is:
arping -U ip
-A -I device
-c count
You could add a line in that file after the arping command to log i

I will try to see if I can get anything from the logs.
If someone else can come to a better suggestion I am all ears.
Not having full access to the DataCenter and the underlying equipment
has caused me enough headaches so far :-(
Best,

Do you mean that OpenStack is sending a gratuitous ARP for all
and the router is ignoring them unless it is for a specific IP address?
If this is the case is the

So according to that it sends ARP every time a floating IP is assigned

If that is correct unfortunately it's not working :-(
Any ideas how to debug it?
Thanks a lot for your help!

Based on the code, it sends the gratuitous ARPs only when the floating IP
is assigned to the VM, and it's sent as many times as the user decided by
configuring the "send_arp_for_ha_count" parameter in nova.conf
So, to be safe, I would add the following in nova.conf and restart nova
services.

George,
how often does it send the gratuitous ARP requests?
Does it send it every time a network change is happening?
Best,
George
You have to set two variables in the nova.conf file apparently
("send_arp_for_ha" and "send_arp_for_ha_count"):
