What is the meaning of VRF, VRF‑Lite and VRF Application Aware?

VRF: It is used by L3VPN. Basically, it is not a protocol or module like OSPF.
          The traditional L3VPN solution includes IP routing protocol, VRF and MPLS.

VRF-Lite: In private network, users can acquire the L3VPN function partly by only using IP
                 routing protocol and VRF, without using MPLS. This is called VRF-lite.
