Abstract: Techniques are described in which a centralized controller constructs a service chain between a bare metal server (BMS) and a virtual execution element (e.g., virtual machine or container), or in some instances a remote BMS, across a plurality of networks. In some examples, the controller may construct a service chain between a BMS and a virtual execution element or remote BMS using Ethernet Virtual Private Network (EVPN)-Virtual Extensible Local Area Network (VXLAN) and Internet Protocol Virtual Private Networks (IP VPNs) such as BGP/Multiprotocol Label Switching (BGP/MPLS) IP VPNs.

Abstract: Techniques are described in which a centralized controller, such as a software defined networking (SDN) controller, constructs a service chain that includes a physical network function (PNF) between a bare metal server (BMS) and a virtual execution element (e.g., virtual machine or container), or in some instances a remote BMS, or vice-versa. In accordance with the techniques disclosed herein, the controller may construct an inter-network service chain that includes PNFs, or a combination of PNFs and virtualized network functions (VNFs). The controller may construct an inter-network service chain to steer traffic between a BMS and a virtual execution element or remote BMS through an inter-network service chain using Virtual Extensible Local Area Network (VXLAN) as an underlying transport technology through the service chain.
