One of the various key features enabled using the OpenStack integration within OpenDaylight is the ability to create a virtual extensible LAN (VXLAN) between hosts and network entities thanks to network, subnet, and port configuration. Using security groups and security rules, you can easily define specifications for groups of ports, either the ingress and/or egress port, within a given namespace, and define rules within the group dictating the allowed behavior.
In this recipe, we will demonstrate network virtualization using VXLAN overlay, along with L3 and floating IP.
