Dear All,
Please do not confuse with MPLS terminology. MPLS VRF(Virtual Router Forwarding Instance) is just a virtual router consisting of one or more number of interfaces. When two or more VRF joins then a VPN is formed. Here joins means sharing the route tables so that they can communicate with each other.
VRF is distinguished by RD(Router Distinguisher). When a VRF import and export routes from another VRF, the virtual router's routing table get exchanged. After that two VRF can communicate with each other. In this case we can say that above two VRF are part of same VPN.
