 Description   

I have 2 VMs each in a different net. Each VM on a different compute.
In each repetition I do the following:
Create router and connect it to both subnets.
create 2 FIPs.
Associate each FIP to one VM.
SSH to one VM and ping to the other FIP from that VM.
SSH to second VM and ping the first FIP.
Delete the 2 FIPs.
Delete router (and its interfaces)

On the second cycle, the SSH to first VM failed.

In the attachments, you can find:
1. q-svc and Karaf logs
2. dump-flows,groups and ports from first VM.
3. dump flows, groups and ports from second vm.
4. Karaf models.
5. output log.
6. Test script.

It seems that the ping request goes from first VM to second VM.
The ICMP request goes to table36.
I didn't understand if the request is good and then the reply fails somewhere between table 17 and table 19 or the ICMP request itself fails after table 36
