Abstract: MPLS is the prime technology used in examine supplier Networks as quick pack forwarding mechanism. It is the tools used in service supplier networks to connect dissimilar remote sites. MPLS can be used to carry any kind of information whether it is layer 2 data such as frame relay, Ethernet, ATM data or layer 3 data such as IPV4, IPV6. MPLS creates two types of VPNs. One is Layer 3 MPLS VPN with Layer 2 MPLS VPN. In Layer 3 MPLS VPN, customer forms IP national distribute with Service Provider device. In Layer 3 VPN routing is performed between client edge device and Provider Edge device. Layer 2 VPNs behave like the consumer sites are connected using a Layer 2 Switch. Various L2 MPLS VPN techniques are Virtual Private LAN Service (VPLS), Virtual Private Wire Service (VPWS), and Ethernet VPN. This paper gives an indication of all these L2 and L3 MPLS VPN technologies.
