A session in the DevNet Zone at Cisco Live, Berlin. One of the key areas of contributions from Cisco within OpenStack has been in the evolution and the development of the OpenStack Networking Service - Neutron. Using Neutron's Modular Layer 2 (ML2) plug-in and advanced services framework, Cisco has integrated products and solutions with the networking service to simplify the deployment of highly scalable, manageable and performant networks. Through this session we will cover and provide details of reference as well as the various OpenStack Neutron plugins/drivers for hardware and software Cisco products including the Nexus 1k/3k/5k/6k/7k/9k, UCS FI, CSR 1kv, ASR1K, CPNR and Application Policy Infrastructure Controller (APIC). The audience will also learn about Group Based Policy API in OpenStack that is based on the ACI Policy model. We will further discuss different OpenStack networking architecture, deployments and understand Ciscoâ€™s community code contribution that enable and support IPv6 and NFV related features in Neutron.
