Scenario - Using the Nuage neutron plugin¶

Introduction¶

Follow these steps to deploy Nuage Networks VCS with OpenStack-Ansible (OSA):

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¶

The deployment environment is configured according to OSA best practices such as cloning OSA software and bootstrapping Ansible. See OpenStack-Ansible Install Guide.
VCS stand-alone components, VSD and VSC, are configured and deployed. See the Nuage Networks VSD and VSC Install Guides.
Nuage VRS playbooks were 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 or editing of parameters in the 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 the /etc/openstack_deploy/ folder.

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

Next, modify the following parameters in that file as per your Nuage VCS environment:

Replace VSD Enterprise Name with the name of VSD Enterprise:
```
nuage_net_partition_name: "<VSD Enterprise Name>"
```
Replace VSD IP and VSD GUI Port as per your VSD configuration:
```
nuage_vsd_ip: "<VSD IP>:<VSD GUI Port>"
```

Replace VSD Username, VSD Password, and VSD Organization Name with your login credentials for the VSD GUI:

nuage_vsd_username: "<VSD Username>"

nuage_vsd_password: "<VSD Password>"

nuage_vsd_organization: "<VSD Organization Name>"

Replace Nuage VSP Version with the Nuage VSP release for Integration. For example, for Nuage VSP release 3.2 this value would be v3_2.
```
nuage_base_uri_version: "<Nuage VSP Version>"
```
Replace Nuage VSD CMS Id with the CMS-Id generated by VSD to manage your OpenStack cluster:
```
nuage_cms_id: "<Nuage VSD CMS Id>"
```
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>"
```
Replace Local Package Repository with the link of the local repository hosting the Nuage VRS packages. For example: http://192.0.2.10/debs/3.2/vrs/:
```
nuage_vrs_debs_repo: "deb <Local Package Repository>"
```

On the Deployment host, add the following lines to the /etc/openstack_deploy/user_variables.yml file, replacing the Local PyPi Mirror URL with the link to the PyPi server hosting the 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¶

After you set up the multi-node OpenStack cluster, start the OpenStack deployment as listed in the OpenStack-Ansible Install guide by running all playbooks in sequence on the deployment host.
After OpenStack deployment is complete, deploy Nuage VRS on all compute target hosts in the OpenStack cluster by running the Nuage VRS playbooks in /opt/nuage-openstack-ansible/nuage_playbook on your deployment host:
```
# cd /opt/nuage-openstack-ansible/nuage_playbooks
# openstack-ansible nuage_all.yml
```
