  • Secure onboarding of network devices
    Patent number: 11463312
    Abstract: Techniques for automated configuration are provided. A first device detects a new device connected by one or more new links in a network, and the first device transmits, to a dynamic host configuration protocol (DHCP) server, a request for a first new subnet. The first device then assigns a first address of the first new subnet to a first new interface of the first device. The first device additionally transmits a second address of the first new subnet to the new device, where the new device uses the second address to establish connectivity to the network.
    Type: Grant

    Date of Patent: October 4, 2022
    Assignee: Cisco Technology, Inc.

  • MICRO AND MACRO SEGMENTATION IN ENTERPRISE NETWORKS WITHOUT A PER SEGMENT LAYER-3 DOMAIN
    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.
