Description Maysa Macedo 2020-09-18 11:46:03 UTC

Description of problem:

When a fip less installation happened with Kuryr and a Service of Load Balancer type was created, a Floating ip gets associated to the load balancer. The clean-up of the custom router would fail due to the subnet being associated to a fip.
