| − | '''This page is a HUGE work in progress!''' | + | Let's take this discussion to the [https://etherpad.openstack.org/p/routed-provider-networks-notes etherpad]. |

| − | As I've been working on routed networks patches, I decided that I should share how I am setting up my environment and using them.

| − | === Segment CRUD ===
| |
| − | | |
| − | There first thing is to enable segment CRUD. [https://review.openstack.org/#/c/296603 This patch] is what you need. It is a service plugin that isn't enabled by default. First, edit
| |
| − | you have the patch, edit ''/etc/neutron/neutron.conf'' and append ''segments'' to the list of ''service_plugins''. Here's mine:
| |
| − | | |
| − | : service_plugins = neutron.services.l3_router.l3_router_plugin.L3RouterPlugin, segments
| |
| − | | |
| − | Since ''segments'' is defined in ''setup.cfg'', you actually need to reinstall neutron for this to work. In devstack, I just do this:
| |
| − | | |
| − | : $ cd /opt/stack/neutron
| |
| − | : $ sudo pip install -e file://$PWD
| |
| − | | |
| − | There is one more change you need to do assuming you're going to use vlans and ML2. You need to edit ''/etc/neutron/plugins/ml2/ml2_conf.ini'' to add your physnets and vlan ranges. I just use the same vlan segment id for each segment. But, the physnet has to be different for each segment.
| |
| − | | |
| − | : [ml2_type_vlan]
| |
| − | : network_vlan_ranges = segment-1:2000:2000, segment-2:2000:2000
| |
| − | | |
| − | At this point, restart the neutron service and then you should be able to create a multi-segmented network. [http://paste.openstack.org/show/495985/ This paste shows a details request / response]. Note that it is not possible to create a multi-segmented network using the python-neutronclient at this time. It is also not yet possible to create or delete segments on an existing network.
