GNS3 lab documenting internal Apache2 web server deployment. Includes Cisco IOSv router, switch, and QEMU Xubuntu clients with SSH access.

Lab work and notes from the Cisco Networking Basics course (NetAcad) | covering IP addressing, subnetting, routing, switching, DHCP, DNS, and wireless config using Cisco Packet Tracer.

Network configuration and troubleshooting exercises focusing on TCP/IP addressing, subnetting, and routing. 10 progressive levels covering subnet masks, CIDR notation, network segmentation, and routing tables. Part of 42 School curriculum.

This Packet Tracer lab demonstrates the configuration of OSPF (Open Shortest Path First) across a multi-router network. It includes tasks such as IP addressing, enabling OSPF on all routers, configuring loopback interfaces, setting passive interfaces, and configuring an ASBR (Autonomous System Boundary Router) to advertise a default route.

Designed and configured a basic inter‑departmental network using Cisco Packet Tracer. Built connectivity between the Accounts and Delivery departments using a router and switches, implemented correct IP addressing and subnetting, and verified communication between all devices through ping tests.
