Abstract

This project presents simulation results on the connectivity, data transfer protocols, reliability, and recovery from failure between two Local Area Networks (LANs), which can be at two geographically distant locations, and are connected through a Wide Area Network (WAN). Connectivity within the WAN is provided by the Border Gateway Protocol (BGP) whereas communication within each of the LANs is based on Enhanced Interior Gateway Routing Protocol (EIGRP). Simulation results show that the network is successful in: (1) establishing communication between the LANs using the BGP protocol, and (2) providing recovery from failure through redundancy by using two BGP links within the WAN and a third Internet Protocol Security (IPsec) link. If one of the BGP link fails, the second one will take over, and if the second link fails, the traffic automatically shifts over to the Internet Protocol Security (IPsec) link.
