摘要： 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.

摘要： A network system that uses a cluster of edge nodes to send and receive multicast traffic is provided. The network system is a network virtualization environment that includes one or more distributed routers, each distributed router implemented by virtualization software running on one or more host machines. The network system also includes a cluster of edge nodes for sending data from the one or more distributed routers to one or more uplink/upstream physical routers outside of a datacenter and for receiving data from the physical routers to the distributed routers. One of the edge nodes is a designated edge node that queries for membership information for one or more multicast groups to be received by at least two edge nodes of the cluster of edge nodes. The cluster of edge nodes forwards multicast traffic to and from the distributed routers according to the received membership information.
