Cisco Networking Labs Crash Course for the CCNA

This course has all the labs you need to practice for a Cisco cert & real w

Instructed by Lazaro (Laz) Diaz

  • After taking this course, the student should be knowledgeable in Cisco equipment (i.e. Routers & Switches), and should be able to grasp the concepts needed to create a network.

 This course is made up of plenty of labs that will give the student the practice needed to be proficient in the main topics that pertains to Routing and Switching for the CCNA certification (200-125) exam.

This is the meat & potatoes of the exam and it will help those in real world scenarios giving the student the foundation needed to start their job in the Networking field.


  • Any simulator that would allow the student to replicate the labs for Cisco.
  • i.e.: Cisco Packet Tracer, VIRL, GNS3, Live Equipment or any other simulator or emulator.
  • Anyone that is studying to take the Cisco CCNA exam or want more information about the equipment used in the real world.
  • Anyone going for an interview and would like to pass that process.

  • In this lecture, I will be showing you how to trunk your required ports using the 8021q Trunking Protocol and why we need to trunk those ports.

Section 4 : Inter-VLAN Connectivity

  • Lecture 1 :
  • Inter-VLAN Connectivity using Layer 3 Switch
  • n this lecture, I will explain and show you how to create inter-vlan connectivity on a Layer 3 switch, instead of your router to create communication between VLAN’s.

Section 5 : Routing across your network using EIGRP

  • Lecture 1 :
  • Configuring the Routing Protocol EIGRP
  • In this lecture, I will show you how to configure EIGRP using a single Autonomous system.This will allow you to be able to route across your network and be able to communicate with all your devices.

Section 6 : Securing our Network

  • Lecture 1 :
  • Configuring Switchport Security
  • In this lecture, I will show you how to configure Switchport Security, so no unwanted devices can connect to your network.
  • Lecture 2 :
  • Creating ACLs using Layer 3 Switch
  • In this lecture, I will show you how to configure ACL’s at the L3 switch, to secure traffic across your VLANs.

Section 7 : NAT Overload Protocol

  • Lecture 1 :
  • Configuring the NAT Overload or PAT Protocol
  • In this lecture, I will be showing you how to configure NAT Overload, since we are going across a simulated WAN, from private network to public network.

Section 8 : Verification of your Configurations

  • Lecture 1 :
  • Troubleshoot or Verify your configurations

  • In this lecture, I will be showing you how to manipulate the election process of STP, by changing the Bridge Priority Number.
  • Lecture 3 :
  • Turning off STP
  • In this lecture, we will be turning off STP on the ports facing end devices using The Portfast command.
  • Lecture 4 :
  • Protecting Ports against Switching loops
  • In this lecture, I will show how to protect your switchports from creating layer2 loops, Using BPDU GUARD command on the ports, that we turned off STP.
  • Lecture 5 :
  • Configuring DHCP on the layer 3 switch
  • In this lecture, I will show you how to configure DHCP on your L3 switch, to allocate IP addresses to end devices.
  • Lecture 6 :
  • Configuring Default and Static Routes
  • : In this lecture, we will be configuring Default routes on your stub routers and static routes on the NYC router, for back up purposes.

Lazaro (Laz) Diaz,

If you are tired of the same old methods of learning and want someone that is pretty much unconventional, but at the same time will provide you with an enjoyable learning experience in layman's terms...then please preview my courses and you will discover that I am your guy. I am a Network Engineer with many years in the field and in the teaching industry. I hold the following certifications: CCNA, CCNA Security, CCNA Voice, CCNP, Security+, Network+, A+, MCP, MCTS & MOS. My teaching experience stems from teaching at various institutions in the US. Now, I bring the classroom to you! I've taught over 100K students worldwide...courtesy of the internet. Thank goodness for technology! ;-) Having been in all sides of the spectrum; as a student, a teacher/trainer, and in the field, I believe this uniquely qualifies me to understand you, the student. I know first hand what you have been exposed to as opposed to what you really want to accomplish. These two are sometimes extremely conflicting and frustrating. That is why I teach in the manner I do and can relate to your rejection of the Status Quo. I have taught corporate employees at MetroPCS (now T-Mobile) and have also taught IT professionals of companies like The Florida Marlins, Ulysse Nardin, Alberta Water Department (Canada), The Assurant Group, Hospital personnel & Attorney's firms, among others. to guide them in acquiring their IT certifications or general knowledge. However, my expertice also extends to being able to teach applications as well. YES!...I am also an applications instructor and qualified to teach Word, Excel, PowerPoint and Access.This, of course, includes the MOS (Microsoft Office Specialist) certification. As you can see, I am a multifaceted person and consider myself to be an eternal student as well. I teach in an unconventional way that allows for students to understand the subject matter and can therefore, not only prepare them for a Cisco, Microsoft or CompTIA certification exam, but apply my methods in the real world. I strive to give the student a greater opportunity to compete in the current job markets. Do I go above and beyond what is needed for a certification?...YES, I do!...because it's not only about getting a certification, it's also about making sure that you, the student, is prepared for a job interview and/or maintaining your current job by enhancing your skills. This is where I step in and make sure that you are prepared for whatever you need and make you an asset to your employer. Everyone has different requirements and I make sure, or at least I try, to provide information for most scenarios. My classes and/or courses are very simple and that's how I like to teach. I truly believe in "KISS",,,NO, I don't want to kiss you, what this means "keep it simple stupid" - If things are kept simple, easily explained in a way that the student can grasp quickly and retain the information...then I have achieved my goal! For those that do not know me yet, you may not be used to my style of teaching, but you will soon get accustomed to it :)... I'm very laid back, I try to make learning fun and I teach in layman's terms...no physics jargon or mumbo jumbo in my teachings. My courses are very interactive and extremely dynamic!...you will not find my lectures monotone or boring, because falling asleep, for lack of excitement, is just NOT an option. Just take a look for yourself at my video previews, which I always provide on ALL my courses, so you can determine if I'm the right guy to help you get your industry specific certifications. ;) I certainly hope that after a careful review of my credentials & testimonials (you can Google it you know!), I'm the Cisco, Microsoft or CompTIA Instructor you're looking for!
