VRF vs VRF-Lite: What's The Difference?
VRF or Virtual Routing and Forwarding is a core network labeling components of MPLS that allows service providers to route traffic of many different clients to many unique VPNs in a fashion that separates each routing table from each other. This standalone routing table is designed with its own rules for sharing and transmitting data and transmits data based on what interfaces are associated with that VRF. The great benefit in this routing protocol within MPLS is it limits the ability for packets to transmit between interfaces in different VRFs allowing service providers granular control over how data is transmitted to their unique client's environment.
VRF-Lite can be thought of as VRF without MPLS. It allows organizations to separate routing via separate routing tables (or VRFs) and limited in how the data is transmitted based on what interfaces with the router.
