Virtual Routing and Forwarding (VRF)

Virtual Routing and Forwarding (VRF) is a technology that allows a single physical network device, like a router, to create multiple separate virtual networks. Each virtual network has its own routing table, ensuring that data from one virtual network stays isolated from others. This enables organizations to securely share infrastructure among different departments or customers, while keeping their traffic separate and private. Think of VRF as having multiple, independent virtual routing environments on one device, allowing efficient, secure, and flexible network management without needing separate hardware for each network.
