Design and Simulation of IPv6-Based VLAN Networks with Switch virtual interface and EIGRPv6 Routing Protocol

Abstract

In contemporary network infrastructure, logical segmentation and efficient routing are crucial for optimizing performance, security, and scalability. This paper presents the design and implementation of VLAN segmentation using Switched Virtual Interfaces (SVIs) in conjunction with EIGRP for IPv6 (EIGRPv6) within a simulated environment using GNS3. VLANs are configured to separate network traffic based on departmental or functional requirements, thereby reducing broadcast traffic and enhancing network organization. SVIs enable inter-VLAN communication by providing Layer 3 interfaces for each VLAN on multilayer switches. EIGRPv6 is implemented as the dynamic routing protocol to ensure efficient routing of IPv6 traffic between VLANs across different network segments. The simulation is carried out using GNS3, evaluating key performance parameters such as convergence time, scalability, and fault tolerance. The results validate the effectiveness of combining IPv6, SVIs, and EIGRPv6 in creating a robust and future-ready network infrastructure.
