OPNFV Summit 2015

OpenContrail provides virtual networking using overlay networking between VMs in an OpenStack environment using a combination of L2 and L3 forwarding in the KVM hypervisor and distribution of routes from the Contrail Controller. In this tutorial we will describe the Contrail Controller architecture, how the route distribution and forwarding is accomplished, and how use of standard data plane and control plane protocols allow OpenContrail virtual networks to be easily connected into physical networks and how physical network functions (PNFs) can be linked with VNFs in service chains
