Ne3007 Advanced Routingproject outline and implementation steps for enterprise network

Implement a comprehensive enterprise-level network using GNS3, involving routing protocol configuration, route redistribution, BGP peering, and security filtering, to demonstrate connectivity and routing efficiency between multiple sites and with external entities in a simulated environment.

Paper For Above instruction

The purpose of this paper is to present a detailed plan and implementation of an enterprise-level network for ABC Pty Ltd, which integrates multiple routing protocols, route redistribution, BGP peering, and security filters to ensure seamless connectivity, optimized routing, and secure network operations. This network simulation employs GNS3 to replicate the detailed topology with configurations adhering to the given scenario, including the various specific tasks corresponding to different stages of network setup. The paper provides a comprehensive explanation of the configuration steps, troubleshooting, and security measures employed, along with a critical analysis of protocol performance, route management, and security considerations.

The network design is based on the provided topology, IP address allocations, and protocol requirements. The initial phase involves configuring the Interior Gateway Protocols—OSPF for ABC Pty Ltd and EIGRP for XYZ Pty Ltd—implementing passive interfaces accordingly and ensuring correct advertisement of networks. Subsequently, the focus shifts to route redistribution between these protocols to facilitate inter-site communication, achieved within Router 1, which manages interactions between the two autonomous systems. The routing setup also involves establishing BGP peering with the ISP router and internal iBGP between Router 1 and Router 2, ensuring proper BGP route advertisement and path selection.

Further, to enhance network security, ingress filtering via route maps is configured on the ISP router to control incoming route updates and safeguard against malicious or erroneous route advertisements. Each configuration step is documented with screenshots and explanations, highlighting key commands and their effects. A critical aspect of the report emphasizes performance issues, such as routing loops or sub-optimal routing paths, and proposes solutions to mitigate these problems. The report also compares OSPF versus EIGRP, discusses passive interface configuration for security enhancement, and evaluates WAN connection options for connecting multiple sites, ensuring a secure, scalable, and efficient network topology.

Throughout the project, emphasis is placed on troubleshooting common issues like adjacency problems, route advertisements, and security filtering; ensuring that the network adheres to enterprise standards. The final configuration demonstrates full connectivity between local sites, with route redistribution, BGP peering, and security configurations verified through testing. The document concludes with recommendations for further optimization and a reflection on the relative advantages of the protocols used, supporting effective decision-making in enterprise network planning.
