While layer 2 networks (point-to-point networks) have their use and are generally fine for data transfers between a few nodes, they’re not built to scale and can become a nightmare for IT teams to manage as your business operation grows. Layer 3 networking enables an easily scalable, full mesh network that reduces operating costs while simplifying IT infrastructure and improving resource management. Plus, layer 3 networks are inherently more efficient at data transmission due to automatic routing.
