  • Patent number: 11533257
    Abstract: Systems, methods, and computer-readable media for interconnecting SDWANs through segment routing. A first SDWAN and a second SDWAN of a SDWAN fabric can be identified. A segment routing domain that interconnects the first SDWAN and the second SDWAN can be formed across a WAN underlay of the SDWAN fabric. Data transmission between the first SDWAN and the second SDWAN can be controlled by performing segment routing through the segment routing domain formed between the first SDWAN and the second SDWAN.

  • Publication number: 20220158869
    Abstract: Secure network segmentation using logical subnet segments is described. A single network segment or subnet provided by a third party is mapped into multiple layer-3 virtual or logical segments without requiring separate subnets. This mapping is accomplished by using virtual routing functions (VRFs) per logical subnet segment while retaining a single subnet across the segments. The logical subnet segments interact with the single network segment provided by the third party (ISP). The layer-3 VRF instances are created without the need for separate IP subnet pools per layer-3 segment. Each VRF instance for the various logical subnet segments is mapped to an identifier and tag.
