Nowadays, the VPN (Virtual Private Network) technique is one of the most common and important implementations in IT and other companies. VPN technology is divided into two categories: (i) overlay VPN and (ii) peer-to-peer VPN. In overlay VPN, ATM and frame relay are included, and peer-to-peer VPN includes IP-routing. VPN technology is becoming more and more important because of its security, convenience of working with VPN, real-time application, and low construction cost. When compared to traditional VPN, MPLS VPN (Multiprotocol Label Switching) is a good solution for real-time. MPLS VPN is an advanced technology, and it has advanced features. MPLS VPN has functions like FEC, VRF, MPBGP, and VPNv4. These functions are used to overcome the disadvantages of traditional VPNs. The disadvantages of traditional VPNs are (i) complex management, (ii) lack of availability, (iii) complex implementation, (iv) expansibility, and (v) customer address overlapping. In this paper, the implementation of the MPLS layer 3 VPN technique is used to connect and share information between different branches of different customers which are geographically separated. Here, a private IP address instead of a public IP address is used to connect and share the information. The MPLS VPN technique is used to provide flexibility for the customer through their ISP (Internet Service Provider).
