Description of problem:
It would appear that some VIPs (see actual results below) are being shared which isn't the expected behavior.  Perhaps this is ok, but we would like to understand why it is this way?  


Version-Release number of selected component (if applicable):
RHEL OSP Director version 8

How reproducible:
Occurs with every overcloud deployment.

Steps to Reproduce:
[osp_admin@director ~]$ heat output-show overcloud --all

Actual results:
