This is where we would see VRFs used in conjunction with multIProtocol BGP and using MPLS traffic labeling at layer three. When we talk about VRF-lite, however, we're essentially referring to the use of VRF without MPLS or multIProtocol BGP. We may typically see VRF-lite used in small enterprise or small data center environments, rather than in large service provider instances. VRF-lite allows us to create multIPle routing tables on a single router that can potentially have overlapping IP address schemes. And it allows us to do that as opposed to requiring separate routers or separate physical connections. So, let's look at a practical example of this. Here we have two routers, R1 one and R2, connected together over a single physical link. And on each side we have two additional routers. We have R3 and R4 connected to R1 and we have R5 and R6 connected…
