Appendix F. Using Nuage Neutron Plugin

Introduction

This document describes the steps required to deploy Nuage Networks VCS with OpenStack-Ansible (OSA). These steps include:

• Install prerequisites.
• Configure Neutron to use the Nuage Networks Neutron plugin.
• Configure the Nuage Networks Neutron plugin.
• Download Nuage Networks VCS components and playbooks.
• Execute the playbooks.

Prerequisites

1. The deployment environment has been configured according to OSA best-practices. This includes cloning OSA software and bootstrapping Ansible. See OpenStack-Ansible Install Guide
2. VCS stand-alone components, VSD and VSC, have been configured and deployed. (See Nuage Networks VSD and VSC Install Guides.)
3. Nuage VRS playbooks have been cloned to the deployment host from https://github.com/nuagenetworks/nuage-openstack-ansible. This guide assumes a deployment host path of /opt/nuage-openstack-ansible

Configure Nuage Neutron Plugin

Configuring the Neutron plugin requires creating/editing of parameters in following two files:

• /etc/openstack_deploy/user_nuage_vars.yml
• /etc/openstack_deploy/user_variables.yml

On the deployment host, copy the Nuage user variables file from /opt/nuage-openstack-ansible/etc/user_nuage_vars.yml to /etc/openstack_deploy/ folder.

# cp /opt/nuage-openstack-ansible/etc/user_nuage_vars.yml /etc/openstack_deploy/

Also modify the following parameters in this file as per your Nuage VCS environment:

1. Replace VSD Enterprise Name parameter with user desired name of VSD Enterprise:

   nuage_net_partition_name: "<VSD Enterprise Name>"
   

2. Replace VSD IP and VSD GUI Port parameters as per your VSD configuration:

   nuage_vsd_ip: "<VSD IP>:<VSD GUI Port>"
   

3. Replace VSD Username, VSD Password and VSD Organization Name with login credentials for VSD GUI as per your environment:

   nuage_vsd_username: "<VSD Username>"
   
   nuage_vsd_password: "<VSD Password>"
   
   nuage_vsd_organization: "<VSD Organization Name>"
   

4. Replace Nuage VSP Version with the Nuage VSP release you plan on using for Integration; For eg: If you seem to use Nuage VSP release 3.2; this value would be v3_2

   nuage_base_uri_version: "<Nuage VSP Version>"
   

5. Replace Nuage VSD CMS Id with the CMS-Id generated by VSD to manage your OpenStack cluster:

   nuage_cms_id: "<Nuage VSD CMS Id>"
   

6. Replace Active VSC-IP with the IP address of your active VSC node and Standby VSC-IP with the IP address of your standby VSC node.

   active_controller: "<Active VSC-IP>"
   
   standby_controller: "<Standby VSC-IP>"
   

7. Replace Local Package Repository with the link of your local repository hosting the Nuage VRS packages, e.g. http://192.0.2.10/debs/3.2/vrs/

   nuage_vrs_debs_repo: "deb <Local Package Repository>"
   

8. On the Deployment host, add the following lines to your /etc/openstack_deploy/user_variables.yml file, replacing the Local PyPi Mirror URL with the link to the pypi server hosting your Nuage OpenStack Python packages in “.whl” format.

   neutron_plugin_type: "nuage"
   nova_network_type: "nuage"
   pip_links:
     - { name: "openstack_release", link: "{{ openstack_repo_url }}/os-releases/{{ openstack_release }}/" }
     - { name: "nuage_repo", link: "<Local PyPi Mirror URL>" }
   

Installation

1. After multi-node OpenStack cluster is setup as detailed above; start the OpenStack deployment as listed in the OpenStack-Ansible Install guide by running all playbooks in sequence on the deployment host

2. After OpenStack deployment is complete; run the Nuage VRS playbooks in /opt/nuage-openstack-ansible/nuage_playbook on your deployment host to deploy Nuage VRS on all compute target hosts in the OpenStack cluster:

   # cd /opt/nuage-openstack-ansible/nuage_playbooks
   # openstack-ansible nuage_all.yml
