  • REFLECTION ROUTE FOR LINK LOCAL PACKET PROCESSING
    Publication number: 20230421487
    Abstract: A method receives a request packet from a workload at a first logical interface of a logical router and determines that a source address is a first link local address for the workload and a destination address is a second link local address for the first logical interface. A second logical interface includes the second link local address. The method stores an identifier for the first logical interface as an egress interface. The identifier distinguishes the first logical interface from the second logical interface. A service is performed for the request packet and a response packet is generated. The response packet includes the source address of the second link local address for the first logical interface and the destination address of the first link local address for the workload. The method uses the identifier to select the first logical interface as the egress interface to send the response packet.

  • Link local address assignment for interfaces of overlay distributed router
    Patent number: 11706191
    Abstract: Some embodiments provide a novel method for assigning a unique internet protocol version 6 (IPv6) link-local address to each interface of a software router implementing a plurality of logical interfaces for a corresponding plurality of logical networks. In some embodiments, the method, for each logical interface, determines a logical network identifier for a logical network corresponding to the logical interface and generates the link-local address based on that logical network identifier (e.g., a virtual network identifier (VNI)).
