They've already been moved from tripleo-ci to tripleo-heat-templates:

We should use the ones for ci, not the examples under
tripleo-heat-templates/network/config. Those examples (especially for
multiple-nics) are meant to be clear and orderly so that users can
easily understand how to adapt them to their own environments.
Especially for multiple-nics, there isn't really a sane default, and I
don't think we should make our examples match what we use in ci.

It may be possible to update ovb so that it deploys virt environments
such that the examples work. That feels like a lot of unecessary churn
though. But even then ci is using mtu:1350, which we don't want in the
examples.

What I'm trying to do in these patches is just use the templates and
environments from tripleo-heat-templates that were copied from
tripleo-ci in 476708. I gathered that was the intent since they were
copied into tripleo-heat-templates. Otherwise, why do we need them
there are at all?

[openstack-dev] [TripleO][CI] Which network templates to use in CI (with and without net isolation)?

[Sagi Shnaidman]

Hi, all

we have now network templates in tripleo-ci repo[1] and we'd like to move
them to tht repo[2] and to use them from there. We have also default
templates defined in overcloud-deploy role[3].
So the question is - which templates should we use and how to configure
them?
One option for configuration is set network args (incl. isolation) in
overcloud-deploy role[3] depending on other features (like docker, ipv6,
etc).
The other is to set them in featureset[4] files for each job.
The question is also which network templates we want to gate in CI and
should it be the same we have by default in tripleo-quickstart-extras?

We have a few patches from James (@slagle) to address this topic[5] and
from Arx for this issue[6].

Please feel free to share your thoughts what and where should be tested in
CI from network templates.

Thanks
