Deploy Multi Protocol Label Switching (MPLS) Using Virtual Routing and Forwarding (VRF)

Abstract

Multi-Protocol label switching(MPLS) that introduced by IETF(Internet Engineering Task Force) is basically used for communication network that attract all service provider network with its brilliant and excellent futures which provide guarantees to traffic and Provide Quality of Services which carries data from source to destination directly through small labels. One of the most highly useful applications of MPLS is VPN or Virtual Private Network that provides layer 3 or network layer VPN for service provider which guarantee carries of traffic privately and securely from one customer to another through service provider network. In order to support several Customers that each customer request for different services like having secure, reliable, private and fast connection MPLS VPN have the concept Virtual Router that it is called VRF(Virtual Routing and Forwarding) table. VRF or Virtual Routing and Forwarding technology that allow a router to have multiple routing tables or multiple VPN at the same time that they are located inside of the same router and now with the help of VRF different customer can use the same Subnet of IP address connected to the same MPLS service provider network. This paper presents deployment of the MPLS using Virtual Routing and Forwarding and using MP-BGP (Multi Protocol Border Gateway Protocol) that I used the combination of IP 4 and IPV6 by using GNS (Graphical Network Simulator)
