Creation of Virtual Private Network Over MPLS Network for Voice over Ip

This paper treats a MPLS-VPN implementation in a network, which was initially configured for fulfilling the demands for mainly voip services.The MPLS network has the important advantage of highest degree of security with better transmission speed which was seeked by many organization all over the world.The network was built in simulator software called GNS3.Intially preliminary configuration are done in all routers with their corresponding ip address with enabling sop protocol in service provider routers to find the shortest path to find the destination routers. Then label distributive protocol (LDP) is enabled with in service provider routers in which routers capable of Multiprotocol Label Switching (MPLS) exchange label mapping information. The Border Gateway Protocol (BGP) is enabled between edge routers and customers to build a virtual private network to enhance voice over ip using MPLS-VPN network. The simulation for this network is verified by using GNS 3 simulator. Key words
