Unfortunately our documentation is usually for newer versions and train
documentation may not be there for ipv6 as we've reworked the network
templates in recent releases. At this point if you're starting from
scratch using Wallaby is a better idea.
If you are looking for some example templates, we actually have a job in CI
that tests this and would have example configurations and commands. This
job only uses ipv6 for the overcloud networks and not for the provisioning
network.
I don't think ipv6 provisioning is fully supported in Train. It might work
but it's something you'd need to do some advanced configuration in order to
get the interfaces correctly configured.
For our CI job, we have example templates in tripleo-heat-templates. These
could be used as a starting point.
https://opendev.org/openstack/tripleo-heat-templates/src/branch/stable/train/ci/environments/network/multiple-nics-ipv6
Our ipv6 job is:
https://review.rdoproject.org/zuul/builds?job_name=periodic-tripleo-ci-centos-8-ovb-3ctlr_1comp-featureset035-train
If you click on the last successful build and click "View log", it'll take
you to our CI logs.
Example:
https://review.rdoproject.org/zuul/build/3190c53f516543edb1844f28004d5c33
View Log takes you to:
https://logserver.rdoproject.org/openstack-periodic-integration-stable4/opendev.org/openstack/tripleo-ci/master/periodic-tripleo-ci-centos-8-ovb-3ctlr_1comp-featureset035-train/3190c53/
All the deployment templates and configurations are located under the
logs/undercloud/home/zuul path.
https://logserver.rdoproject.org/openstack-periodic-integration-stable4/opendev.org/openstack/tripleo-ci/master/periodic-tripleo-ci-centos-8-ovb-3ctlr_1comp-featureset035-train/3190c53/logs/undercloud/home/zuul/
For ipv6 the network configuration, the important flags/options to
`openstack overcloud deploy` would be:
-n network_data.yaml
This by default uses network_data.yaml from tripleo-heat-templates. This
has the ip information for the various networks. You can take the default
and copy/update it to fit your needs. This file is used to generate some
of the network configurations during the deployment.
-e
/usr/share/openstack-tripleo-heat-templates/environments/network-isolation-v6.yaml
This environment file enables ipv6 for ports and configures all the
networks for use. This also has examples on overriding default ips.
-e
/usr/share/openstack-tripleo-heat-templates/ci/environments/network/multiple-nics-ipv6/network-environment.yaml
-e /home/zuul/network-environment.yaml
These configuration files contain the references for the network interface
configs as well as setting the ranges necessary for the pools.
Good luck.
