[Bug 1709774] Re: Multiple router_centralized_snat interfaces created during Heat deployment

 

>From my initial findings this does look like some kind of race condition
server side in Neutron and isn't an issue with Heat.

Title:
  Multiple router_centralized_snat interfaces created during Heat
  deployment

Status in OpenStack Heat:
  Invalid
Status in neutron:
  Triaged

Bug description:
  While attempting to deploy the attached hot template I ran into a few
  issues:

  1. Multiple router_centralized_snat interfaces are being created.
  2. One router_centralized_snat interface is created, but it's Down.

  When Multiple interfaces are created the stack can't be deleted. I
  need to manually delete the additional ports that have been created
  before the stack can be deleted.

  I'm using Newton with OVS+DVR.

  
  I should state up front that the `depends_on` that are in the template are more of a last ditch effort than anything else, and are likely incorrect. However, without them the problem still exists.
