What is VRF-Lite?

VRF-Lite is a feature that enables multiple routing instances on a single router. It allows a router to have multiple forwarding tables, effectively creating virtual routers within a physical router. This is commonly used to segment networks, such as separating customer networks in a service provider environment or isolating different departments within an enterprise network. Each VRF operates as an independent router, with its own routing table, forwarding table, and routing protocol instances.
