Design & Implementation a Corporate Network Using Inter-Vlan Routing Protocol

Abstract

Every small and large organization use computer network to share their resources. The size of network is increasing day by day. They are connecting their network to the public network such as Internet.A network has been designed that represents a real time environment of an organization. The organization has been subdivided into different departments by implementing VLANs for proper management. Also these different departments can communicate with each other using Inter VLAN Routing for controlled flow of information. An ISP environment has been created using NBMA frame relay to control traffic. Redistribution of routing protocols is being used for better routing OSPF protocols. PRAN RFL GROUP company whose have main 7 branches and 7 sub branches in Bangladesh. In future this company will increase their sub benches. 7 divisions have 7 main branches and 7 districts have 7 sub branches in Bangladesh. Every main branches have Admin VLAN and sub branches have MKT and SALES VLAN. Main and sub branches VLAN will increases day by day. For intercommunicating all VLAN, we use inter-VLAN Routing with OSPF Routing protocol. First, in this project we configure 7 main branches and also 7 sub branches. Second, we create VLAN all main branches and sub branches. Third, we configure OSPF in all main branches Router and sub branches Layer-3 switch. Finally, we configure inter-VLAN Routing in all main and configure.
