Not exactly like that. None of the providers are added to the physical
network by default if execute createPhysicalNetwork call via API. Our CS
UI does this job - adding the providers to the network - for you by
calling addNetworkServiceProvider call.

So while you were on 4.1.1, GRE isolation was disabled? Did you enable it
on 4.3? If there is a way to enable new isolation on the physical network,
on my opinion - the UI should perform the background call and add all the
providers associated with this option, to the physical network. So it
would be a UI issue.

Or the case was the following - the GRE isolation was enabled on your
network while on 4.1.1, but new provider - OVS - was added in 4.3. And
this provider wasn’t added to existing physical networks during the
upgrade. Then its a database upgrade bug.


Please confirm which one from the above is correct.
