The Arista OpenStack solution automates the provisioning of VLANs on Arista switches to work in concert with the OVS plugin. This is in contrast to the other OpenStack plugins available today, which allow deployment of either the virtual switch plugin or the hardware device plugin, but not both. The architecture implemented is open and vendor agnostic.Providing this capability within the OpenStack solution is a significant achievement for integration with physical network devices. The availability of the drivers published back into the OpenStack community by Arista Networks can lead to truly multi-vendor solutions for VLAN provisioning automation within OpenStack environments.
