Project Overview
This project focuses on designing and configuring a high-availability, multi-segment local area network using Cisco Packet Tracer. The topology incorporates three distinct subnets—VLAN 10 (`10.10.10.0/24`), VLAN 20 (`20.20.20.24`), and VLAN 30 (`30.30.30.0/24`)—connected across Layer 2 access and multilayer switches.
Key technical components implemented in this project include:
* **PAgP EtherChannel:** Port aggregation using Cisco's Port Aggregation Protocol (PAgP) across redundant FastEthernet links to increase bandwidth and provide link redundancy between switches.
* **Inter-VLAN Routing:** Router-on-a-Stick architecture configured via subinterfaces on a Cisco 2911 router to route traffic seamlessly between segregated VLANs.
* **Centralized DHCP Server:** Dynamic IP address allocation configured directly on the edge router to serve host devices in each respective VLAN automatically.
