VXLAN overlay networks with Open vSwitch. • Twitter: @davidmahler • LinkedIn: / davidmahler • Demonstration of configuring a VXLAN tunnel manually using Open vSwitch. Connecting VMs together through the tunnel, allowing logical separation of tenant traffic from each other and from the physical underlay network.
