Packet Tracer Labs
Practicing is a vital component of mastering networking, as true expertise is developed through solving real-world challenges and applying theoretical knowledge to practical scenarios.
In this section, you'll find a collection of the most significant labs I've worked on, each one crafted to cover the full spectrum of concepts, protocols, and technologies encompassed in the CCNA curriculum. For each lab, I’ve provided the instructions that I was given along with a concise summary that outlines the core objectives and key takeaways. Additionally, you’ll find an overview of the essential skills and concepts that were necessary to successfully complete each lab.
1.lMultiarea OSPF
Level: CCNA3
Technologies: Multiarea OSPF, HSRP, Etherchannel, DHCPv4, subnetting, STP, VLANs, Inter-VLAN-routing, DNS, HTTP/HTTPS, EMAIL
Description: This lab simulates a company infrastructure with a central headquarters and multiple branch locations, all connected through Multi-Area OSPF for optimized routing. Router IDs were configured for each router - improving network documentation and identification - and passive Interfaces to minimize OSPF processing overhead on non-routing links. The headquarters network is designed following Cisco's 2-tier architecture principles, ensuring a robust and scalable core-distribution design.
2.lCCNA2 recap lab
Level: CCNA2
Technologies: IPv4, IPv6, Etherchannel, VLANs, STP, Inter-VLAN-Routing, HSRPv2, static routing (default, summary and floating routes), Port-security, DHCP Snooping, Portfast & BPDU Guard, SSH, DHCP, DNS, HTTP/HTTPS, EMAIL
Description: This lab simulates a company infrastructure with three main networks. Redundancy has been configured at both Layer 2 and Layer 3, and the best security practices have been implemented across all device configurations. The topology is dual-stack, supporting both IPv4 and IPv6 protocols.
3.lIPv4 subnetting & static routing
Given the network address 192.168.1.0/24, I subneted it into 5 networks, each with a different number of hosts, while optimizing the use of addresses. I configured connectivity through static routing for both IPv4 and IPv6. You can see the instructions addressing table for reference.
Level: CCNA1
Technologies: IPv4, IPv6, VLSM, static routing
