Exploring network namespaces
Network namespaces allow you to create isolated views of the network. A namespace has a unique routing table that can differ entirely from the default routing table on the host. In addition, you can map interfaces from the physical host into namespaces for use within the namespace. The behavior of network namespaces closely mimics that of Virtual Routing and Forwarding (VRF) instances, which are available in most modern networking hardware. In this recipe, we'll learn the basics of network namespaces. We'll walk through the process of creating the namespace and discuss how to use different types of interfaces within a network namespace. Finally, we'll show how to connect multiple namespaces together.
