Abstract: A method for creating overlay networking constructs to establish network connectivity between virtual routers and remote physical gateways is provided. An orchestrator receives a mapping between tenant network identifiers for multiple tenant networks and overlay network identifiers for multiple overlay networks. The orchestrator attaches a virtual router to a parent logical port of an overlay logical switch for connectivity between a physical gateway and the multiple tenant networks. The orchestrator creates multiple child logical ports that are sub-interfaces of the parent logical port. Each child logical port is uniquely identified by a tenant network identifier. The orchestrator connects multiple child logical switches to the multiple child logical ports according to the received mapping. Each child logical switch is uniquely identified by an overlay network identifier. The orchestrator establishes multiple overlay networks based on the child logical switches to tunnel data between the physical gateway and the child logical ports.
