Intent-based networking (IBN) is an emerging networking architecture that enables the network to be managed and automated based on business policies and intents. It uses software-defined networking (SDN) and network automation to simplify network management, reduce operational costs, and improve network security.
To migrate from a traditional campus design to a programmable fabric design using IBN, the network must be designed in a way that allows for easy integration with IBN technologies. The following are the design options that facilitate a migration from a traditional campus design to a programmable fabric design:
A. Two-tier: This design is a traditional campus network design that consists of a core layer and an access layer. The core layer provides high-speed switching and routing functions, while the access layer provides connectivity to end-user devices. This design can be easily integrated with IBN technologies by implementing software-defined access (SD-Access), which is a Cisco technology that provides automated network segmentation, policy-based access control, and network-wide visibility.
B. Layer 2 access: This design is similar to the two-tier design, but it uses Layer 2 switching instead of Layer 3 routing at the access layer. This design is typically used in small to medium-sized networks and can be easily integrated with IBN technologies by implementing SD-Access.
C. Three-tier: This design is a campus network design that consists of a core layer, a distribution layer, and an access layer. The distribution layer provides policy-based connectivity between the core and access layers, while the access layer provides connectivity to end-user devices. This design can be integrated with IBN technologies by implementing SD-Access and software-defined WAN (SD-WAN), which is a Cisco technology that provides automated network routing, policy-based traffic steering, and application visibility.
D. Routed access: This design is a campus network design that uses Layer 3 routing at the access layer instead of Layer 2 switching. This design provides better scalability and security than Layer 2 access designs and can be integrated with IBN technologies by implementing SD-Access and SD-WAN.
In summary, the two-tier, Layer 2 access, three-tier, and routed access designs can all facilitate a migration from a traditional campus design to a programmable fabric design using IBN. The choice of design depends on the size and complexity of the network, as well as the specific requirements of the organization.
