In this post I’ll show how to build a dockerized OpenStack and OpenContrail lab, integrate it with Juniper MX80 DC-GW and demonstrate one of Contrail’s most interesting and unique features called BGP-as-a-Service
In this post I’ll demonstrate how to build a simple OpenStack lab with OpenDaylight-managed virtual networking and integrate it with a Cisco IOS-XE data centre gateway using EVPN
In this post I’ll show how to configure Neutron’s service function chaining, troubleshoot it with Skydive and how SFC is implemented in OVS forwarding pipeline
I’m returning to my OpenStack SDN series to explore some of the new platform features like service function chaining, network service orchestration, intent-based networking and dynamic WAN routing. To kick things off I’m going to demonstrate my new fully-containerized OpenStack Lab that I’ve built using an OpenStack project called Kolla
In this post we will see how OVN implements virtual networks for OpenStack. The structure of this post is such that starting from the highest level of networking abstraction we will delve deeper into implementation details with each subsequent section. The biggest emphasis will be on how networking data model gets transformed into a set of logical flows, which eventually become OpenFlow flows. The final section will introduce a new overlay protocol GENEVE and explain why VXLAN no longer satisfies the needs of an overlay protocol.
This is a first of a two-post series dedicated to project OVN. In this post I’ll show how to build, install and configure OVN to work with a 3-node RDO OpenStack lab
