Abstract

Modern enterprises are heavily dependent on secure and dependable networks; however, challenges such as network failures, less-than-optimal routing, and a lack of security prevail. This research introduces the design and simulation of a redundant enterprise network based on collapsed core network topologies interlinking headquarters, branch offices and a central server. Virtual LANs (VLANs) and Access Control Lists (ACLs) are integrated for better segmentation and security, OSPF is used for efficient routing, and HSRP is used for gateway redundancy. A structured Variable Length Subnet Masking or VLSM scheme is implemented to better use the IP address. Simulation in Cisco Packet Tracer shows that we have successfully proposed inter-VLAN communication, access control and failover functions. The proposed model provides a cost-efficient model for building resilient enterprise networks.
