EVPN host routed bridging (HRB) and EVPN cloud native data center

A data center network system comprising:

• a plurality of host computing devices interconnected by a switch fabric comprising a plurality of physical network switches;
• an orchestrator configured to deploy pods for executing one or more containerized user-level applications on processing circuitry of the host computing devices;
• a plurality of cloud native virtual routers executing on the host computing devices,
• wherein at least a containerized routing protocol process of each of the plurality of cloud native virtual routers is configured as a pod for deployment by the orchestrator as a containerized user-level application of the one or more containerized user-level applications;
• wherein each of the cloud native virtual routers comprises:
• the containerized routing protocol process configured to operate as a control plane for the cloud native virtual router, wherein the containerized routing protocol process is further configured to program a data plane to provide a set of one or more layer two (L2) bridging domains connected to a layer three (L3) virtual routing and forwarding (VRF) data structure for an ethernet virtual private network (EVPN) overlay network for communicating layer two (L2) network traffic between the one or more containerized user-level applications via the switch fabric of the data center, and
• the data plane providing the set of one or more L2 bridging domains;
• and
• a container network interface (CNI) configured to:
• receive data specifying a high-level intent for an EVPN encapsulation/decapsulation data path for a containerized user-level application of the one or more containerized user-level applications configured for dynamic deployment by the orchestrator;
• translate the data specifying the high-level intent into configuration data;
• and
• based on the configuration data, dynamically set up the EVPN encapsulation/decapsulation data path to provide a network connection between the containerized user-level application for deployment by the orchestrator and a desired bridge domain of the EVPN encapsulation/decapsulation data path.

A method comprising:

• receiving, with a secondary container network interface (CNI) associated with a containerized virtual network router deployed to a host server of a data center, data specifying a high-level intent for an ethernet virtual private network (EVPN) encapsulation/decapsulation data path for a containerized user-level application, the containerized user-level application to be deployed on a host computing device by a data center orchestration engine of the data center,
• translating, with executable instructions of the secondary CNI, the data specifying the high-level intent into configuration data for the EVPN encapsulation/decapsulation data path, and
• dynamically setting up the EVPN encapsulation/decapsulation data path with the executable instructions of the secondary CNI to provide a network connection between the containerized user-level application to be deployed and a desired bridge domain within a data plane of the containerized virtual network router for the EVPN encapsulation/decapsulation data path,
• wherein the containerized virtual network router comprises a containerized routing protocol process configured to operate as a control plane for the containerized virtual network router and configured to program the data plane of the containerized virtual network router for the EVPN encapsulation/decapsulation data path.
