Description Harald Jensås 2018-09-05 06:53:21 UTC 
Description of problem:
-----------------------

When deploying the undercloud support for routed networks must be enabled using the enable_routed_networks option in undercloud.conf. If the option is set to False (the default) it is not possible to change it to True and re-run undercloud installer to enable support for routed networks.

Prior to Rocky it had to be like this because neutron did not support migrating a non-routed network to a routed network.

How reproducible:
-----------------

Easy

Steps to Reproduce:
-------------------

1. Deploy undercloud with `ènable_routed_networks = False`
2. Change to `enable_routed_networks = True" and re-run undercloud installer

Actual results:
---------------

Only the `local_subnet` is created.
Additional segments and subnets are not created.
The subnet does not have association with a segment.

Expected results:
-----------------

 * All subnets defined in undercloud.conf should be created.
 * All ctlplane segments defined in undercloud.conf should be created.
 * All ctlplane subnets defined in undercloud.conf should be created.
 * All ctlplane subnets should be associated to segments.

Additional info:
----------------

Once routed networks is enabled, it cannot be disable.
