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][openstack-post-2] we can start exploring how virtual networks are implemented under the hood
In the previous post I’ve demonstrated how to get a working instance of a single-node OpenStack inside UNetLab. In this post we’ll continue building on that by adding two new compute nodes and redesigning our network to resemble something you might actually see in a real life.
