Implementation of MPLS L2.5 VPN in an Enterprise Network Environment

摘要

Telecommunication service providers used different type of services like TDM technologies for real time voice, frame relay and ATM for private network services which all are out-dated. Nowadays the enterprise networks needed Layer 2.5 Multiprotocol Label Switching (MPLS) and Virtual Private Networks (VPN). This will reduce downtime and so prevents the revenue loss by forming future proof network architecture includes Software Defined Networking (SDN). This forms flexible solution topology to give better changing in business requirements. Using MPLS as a backbone encapsulation is not needed because VPN provides fully independent architecture and transparent to other customer. The MPLS router performs routing by using Label values and completes the routing operation. Hence research was done for this layer 2.5 network and a scenario made by using real CISCO IOS image in GNS3 software and labels were captured by using WIRESHARK.
