Abstract: Virtual network controllers are described that automatically generate policies and configuration data for routing traffic through physical network function (PNF) service chains in a multi-tenant data center. An example network controller includes a memory and processing circuitry configured to: automatically generate, for one or more integrated routing and bridging (IRB) units of corresponding virtual network forwarding tables of a switch of a switch fabric of a data center network, configuration information that, when deployed, causes the IRB units to direct data traffic conforming to multiple communication protocols and flowing over a plurality of virtual networks between a first set of server devices and a second set of server devices positioned outside of the switch fabric (i) toward a service device logically positioned outside of the switch fabric and coupled to the switch, and (ii) back from the service device into the switch fabric via the switch.
