The MPLS works start between one end PE to other end PE routers. What is VRF lite? VRFs as VPN Routing and Forwarding instances, are most commonly associated with MPLS service providers. In such networks, MPLS encapsulation is used to isolate individual customers' traffic and an independent routing table (VRF) is maintained for each customer. Mostly the MP-BGP is employed to facilitate complex redistribution schemes to import and export routes to and from VRFs to provide Internet connectivity. VRF-lite is a feature in MPLS environment that enables a service provider to support two or more VPNs, where IP addresses can be overlapped among the VPNs. VRF-lite uses input interfaces to distinguish r...
