MultiProtocol Label Switching (MPLS) is a method for fast packet forwarding within a network. It uses label instead of IP for forwarding of packets. Virtual Private Network (VPN) is implemented to provide an end-to-end connectivity among non-directly connected nodes. VPN is used in MPLS to provide a connection oriented service over non-connected nodes of a network. Layer 2 (L2) MPLS and Layer 3 (L3) VPN is based on logical implementation of tunnels for forwarding of packet.
