Abstract This project purpose is Dynamically Reconfiguration the Virtual LAN with the redundancy network line. In a Network Topology where use redundancy network line which is configured by dynamically. That means the redundancy network line will be working dynamically. For this dynamic reconfiguration, use BGP & Static routing protocol. If the BGP protocol failed or not working, then Static routing will be working. It’s working on two different offices like main office & branch office which connected with two different ISP. Branch office connected with Main office by two ISP which one ISP is primary network line & another is redundancy network line. And all routers are configured by BGP & Static routing protocol. If one ISP network line is down, then another ISP network line is working dynamically. So that there is no network interruption between two offices. Keywords: Dynamic, Virtual LAN, BGP, ISP
