Architecture for MPLS L3 VPN Deployment in Service Provider Network

Abstract

Now a days in Service Provider’s core network we do not use IP forwarding rather we go for MPLS because it gives more efficient switching of packets. MPLS is the combination of layer-3 routing and layer-2 switching because every network prefix is assigned a particular Label. In this paper I am going to do testing and implement scalability over MPLS L3 VPN. This testing and implementation are to proof the scalability is the one important thing when design MPLS L3 VPN technology. This Topology of MPLS L3 VPN also provides the secure tunnel between two customer sites. By this implementation we show that there is a transparent tunneling over SP network. We are also avoiding the BGP implementation In SP core. So we call it as BGP free core. This implementation also saves the routing table space on provider routers. We have used the concept of Route Reflector (RR) to avoid more BGP sessions and to make it more scalable.
