VRF - virtual routing and forwarding
Virtual Routing and Forwarding (VRF) is an IP (Internet Protocol) technology in some network routers that can be configured to allow multiple instances of a routing table on your router to work at the same time. The multiple routing instances are independent, allowing the same or overlapping IP addresses to be used without conflict. You can use the same IP address assigned to two different interfaces on a router at the same time.
