In this post we’ll use Chef, unnumbered BGP and Cumulus VX to build a massively scalable “Lapukhov” Leaf-Spine data centre.
In this post we will explore what’s required to perform a zero-touch deployment of an OpenStack cloud. We’ll get a 3-node lab up and running inside UNetLab with just a few commands.
One of the basic function of any data centre network is the ability to communicate with baremetal servers. In this post we’ll see how Neutron L2 Gateway plugin can be used to configure a Cumulus VX switch for VXLAN-VLAN bridging.
In the this post we’ll tackle yet another Neutron scalability problem identified in my earlier post - a requirement to have a direct L2 adjacency between the external provider network and the network node.
In the previous post we’ve had a look at how native OpenStack SDN works and what are some of its limitations. In this post we’ll tackle the first one of them - overhead created by multicast source replication.
Now that we have our 3-node OpenStack lab up and running we can start exploring how virtual networks are implemented under the hood.
In this post I’m going to show how to get a running instance of Openstack inside a UNetLab virtual machine.
The final post in a series demonstrates how to use the network-ci tools to safely replace a core routing protocol inside a small Active/Standby Data Centre.
In this post I’ll demonstrate how to use the network-ci tools to automate the build, test and upgrade of a small 4-node network topology.
