Open Stack

Hi Salvatore,

Thanks for emailing! So from what I can see from the guide, Im only
supposed to edit the l3_agent.ini file on the network node. There is
nothing for l3_agent.ini on controller to edit from the guide. I did see
this as I continued to troubleshoot after my original email on the
controller node:

 systemctl status neutron-l3-agent.service
neutron-l3-agent.service - OpenStack Neutron Layer 3 Agent
   Loaded: loaded (/usr/lib/systemd/system/neutron-l3-agent.service;
disabled)
   Active: failed (Result: exit-code) since Tue 2014-11-18 16:29:19 EST;

  Process: 6063 ExecStart=/usr/bin/neutron-l3-agent --config-file

Nov 18 16:31:18 controller systemd[1]: Stopped OpenStack Neutron Layer 3

And when I went and looked at these logs I see:

[root at controller neutron]# more l3-agent.log
2014-11-18 16:29:19.519 6063 INFO neutron.common.config [-] Logging enabled!
2014-11-18 16:29:19.520 6063 ERROR neutron.agent.l3_agent [-] An interface
driver must be specified

So Im not sure if thats what you are talking about - Am I supposed to do
what I did for the controller node l3_agent.ini I did for the network node
(below)? What about the compute node? Am I not sure what you mean by having
l3 plugin not configured in my neutron.conf.  How do I do that? I have
 service_plugins = router currently. And which neutron.conf do I need to
edit as I have 3, one for each node.  I will def post this answer up and
answered when finished on openstack as I cant find any relevant question
asked about this. Thank you very much!!

*To configure the Layer-3 (L3) agent*

The Layer-3 (L3) agent
<http://docs.openstack.org/juno/install-guide/install/yum/content/neutron-network-node.html#>
provides
routing services for virtual networks.

   -

   Edit the /etc/neutron/l3_agent.ini file and complete the following
   actions:
   1.

      In the [DEFAULT] section, configure the driver, enable network
      namespaces
      <http://docs.openstack.org/juno/install-guide/install/yum/content/neutron-network-node.html#>,
      and configure the external network bridge:
      [image: Select Text]
      1
      2
      3
      4
      5
      [DEFAULT]
      ...
      interface_driver = neutron.agent.linux.interface.OVSInterfaceDriver
      use_namespaces = True
      external_network_bridge = br-ex
      2.

      (Optional) To assist with troubleshooting, enable verbose logging in
      the [DEFAULT] section:
      [image: Select Text]
      1
      2
      3
      [DEFAULT]
      ...
      verbose = True
