Tutorial confirmed: "Using the VRF Implementation in Linux" (David Ahern)


Support for Virtual Routing and Forwarding (VRF) was recently added to the Linux kernel. Core IPv4 support is in v4.3 and core IPv6 support is in v4.4. This tutorial introduces users to the VRF implementation, showing them how to create and configure VRFs, expectations for processes, and commands to show VRF based configuration and debugging. A few typical VRF use cases will be covered, such as basic management VRF, VRFs with VLANs, VRFs with MPLS and inter-VRF routing.
