This notebook demonstrates how to provision and configure a Layer 2 network topology using P4 programmable Tofino switches on the FABRIC testbed. Specifically, it leverages the Edgecore Wedge100BF-32X switch, which features a Barefoot Tofino ASIC, for deploying and testing custom P4 programs.

• Create a slice with Tofino-enabled nodes and appropriate interfaces
• Configure a Layer 2 stitched network between hosts connected via the Edgecore Wedge100BF-32X
• Deploy and validate P4 runtime behavior using pre-defined forwarding programs
• Test end-to-end connectivity across the Layer 2 domain

The notebook is intended for researchers and developers exploring network programmability, P4-based data plane experimentation, and Layer 2 service composition in a deeply programmable infrastructure.

Prerequisites include familiarity with the FABlib API and access to a FABRIC project with slice creation privileges.
