Fixed In Version:	openstack-tripleo-heat-templates-0.8.6-44.el7ost	Doc Type:	Bug Fix
Doc Text:	Prior to this release, the allow_overlapping_ips Neutron setting was left at default. As a consequence, allow_overlapping_ips in Neutron was disabled, preventing definition of multiple networks with the same ranges. This problem has been fixed by setting allow_overlapping_ips to "true", and as a result, networks with overlapping ranges can be defined.	Story Points:	---

Description Attila Darazs 2015-07-17 13:47:08 UTC

Description of problem:
In /etc/neutron/neutron.conf we have

allow_overlapping_ips = False

This is not optimal for a default neutron installation and breaks tempest tests that assume this is the default.

Version-Release number of selected component (if applicable):
openstack-tripleo-heat-templates-0.8.6-43.el7ost.noarch

How reproducible:
100%

Steps to Reproduce:
1. Deploy overcloud with default settings
2. check /etc/neutron/neutron.conf

Actual results:
False

Expected results:
True

Comment 3 Jiri Stransky 2015-07-17 14:00:51 UTC

Patch tested upstream:

[root@overcloud-controller-0 ~]# grep ^allow_overlapping_ips /etc/neutron/neutron.conf
allow_overlapping_ips = True

[root@overcloud-novacompute-0 ~]# grep ^allow_overlapping_ips /etc/neutron/neutron.conf
allow_overlapping_ips = True
