Due to a ransomware attack, the wiki was reverted to a July 2022 version. . We apologize for the lack of a more recent valid backup.

This page is obsolete and will be removed soon, please see https://wiki.opencord.org/display/CORD/VTN+Developer+Information instead. | ||
| Note | ||
This page explains how to set up and use the CORD-VTN service manually. It is possible to test CORD-VTN without XOS, but it is recommended to set up CORD-VTN with XOS. This link https://github.com/open-cloud/xos/blob/master/xos/configurations/cord-pod/README.md would be helpful if you're going to build whole CORD test environment. |
You will need:
- An ONOS cluster installed and running
- An OpenStack service installed and running ("stable/mitaka" version is used here)
- An XOS installed and running (optional if you need to test CORD VTN functionalities only, not the other CORD services)
| Note |
|---|
Note that official CORD reference implementation deploys all controller services including ONOS, OpenStack and XOS run on the one single "head node" but this page deploys the controller services in separate nodes. |

Architecture
The high level architecture of the system is shown in the following figure.
...
- Bootstraps OVS and "br-int" interface in a compute node to be controlled by ONOS and CORD-VTN properly
- Provides a basic connectivity among all VMs in the same service(i.e. same Neutron network).
- Provides an external connectivity to a VM with public type of service network.
- Provides a local management connectivity, which is a limited connection between a VM and compute node.
- Provides a service dependency between two services. It guarantees forwarding all traffics from 'service A', which is tenant service, to one of the VM of 'service B', which is provider service.
- Provides WAN and LAN connectivities for vSG container.
- Provides APR ARP and DHCP proxy for the virtual networks.

Let's install networking-onos (Neutron ML2 plugin for ONOS) first.
| Code Block | ||
|---|---|---|
| ||
$ mkdir -p /opt/stack && cd /opt/stack
$ git clone https://github.com/openstack/networking-onos.git
$ cd networking-onos
$ sudo python setup.py install |
Specify ONOS access information. Specify ONOS access information. You may want to copy the config file to /etc/neutron/plugins/ml2/ where the other Neutron configuration files are.
