Neutron is a virtual network service for Openstack, and a part of Netstack. Just like OpenStack Nova provides an API to dynamically request and configure virtual servers, Neutron provides an API to dynamically request and configure virtual networks. These networks connect "interfaces" from other OpenStack services (e.g., virtual NICs from Nova VMs). The Neutron API supports extensions to provide advanced network capabilities (e.g., QoS, ACLs, network monitoring, etc.) . This charm provides the OpenStack Neutron API OpenContrail agent, managing L2 connectivity on neutron-api services.

OpenContrail (www.opencontrail.org) is a fully featured Software Defined Networking (SDN) solution for private clouds. It supports high performance isolated tenant networks without requiring external hardware support. It provides a Neutron plugin to integrate with OpenStack.
This charm is designed to be used in conjunction with the rest of the OpenStack related charms in the charm store to virtualize the network that Nova Compute instances plug into.
This subordinate charm provides the Neutron API component which configures neutron-server for OpenContrail. Only OpenStack Icehouse or newer is supported.
Neutron API, Contrail Configuration and Keystone are prerequisite services to deploy.
Neutron API should be deployed with legacy plugin management set to false:
neutron-api: manage-neutron-plugin-legacy-mode: false
Once ready, deploy and relate as follows:
juju deploy neutron-api-contrail juju add-relation neutron-api neutron-api-contrail juju add-relation neutron-api-contrail contrail-configuration juju add-relation neutron-api-contrail keystone
The version of OpenContrail installed when deploying can be changed using the 'install-sources' option. This is a multilined value that may refer to PPAs or Deb repositories.
