As a network engineer with years of experience in the field, I have accumulated a vast array of certifications from various providers. From Citrix to Microsoft to Annabelle, I have earned certifications in a wide range of areas, including Proxima, Wi-Fi, 3com, and Asterisks IP phone systems. I have also worked with den net and Novell networks, and have developed my skills to become a Level Engineer and a CCNP Route-certified engineer.

I have found that as the field of network engineering evolves, so too do the certifications available. The CCNA, which I first earned in 2002, has undergone changes, and there is now a greater emphasis on topics such as border gateway protocol (BGP). This has required me to break down the subject matter into smaller pieces and focus on lab work to fully understand it.

To prepare for the CCNP Route exam, I have been studying and using virtual software and labs. While many people recommend GNS3, I have found that it is difficult to find the specific IOSs required, and it does not work well for switches. Instead, I have used Cisco's Packet Tracer program, which is available for free with a sign-up. While it does have some issues with frame relay and OSPF, it works well for my needs.

While virtual labs and software are helpful, there is no substitute for hands-on experience with real equipment. Fortunately, I have had access to free routers, including 2600 and 2800 series routers, and have been able to set up my own home lab. However, for those pursuing higher-level certifications, such as the CCIE, access to Cisco's virtual lab environments may be necessary.

As I continue to set up my home lab, I've come across some cost-saving measures that I'd like to share with fellow network enthusiasts. One thing that I've found to be sufficient for routing is using a single router with VLANs. By creating VLANs, you can logically separate your network without needing multiple routers. Additionally, instead of investing in expensive DCE serial cards and cables, I've found that using T1 cards with a T1 crossover cable works just as well for simulating frame relay switching.

Another tool that has been helpful for me is the Moxa terminal server. With this device, you can remotely access the console port of each router in your lab from your laptop. This is particularly useful because it allows you to make changes to the network without having to be directly connected to the router, which can potentially cause loss of connectivity. And don't forget to stock up on cables of all types, including T1 crossover cables, Ethernet crossovers, and straight-through Cat 5 cables. It's also a good idea to invest in a set of crimpers and RJ45 connectors so that you can make your own custom cables in a pinch.

In terms of hardware, I've been using a mix of 2600 routers and Cisco switches. For switches, I've found that the old 2950 and 3560 models work well for basic switching needs, but if you can get your hands on a 3560, it has more advanced capabilities such as the ability to create VLANs that only talk to certain other ports. While this may be more of a CCIE level concept, it's good to have exposure to advanced networking concepts as you build your skills.

As I continue to work towards my CCMP certification, I have been acquiring the necessary equipment for my lab. Most of the equipment I obtained was used and purchased from eBay. I also received some equipment as gifts from fellow professionals.

One thing I have learned is that having the right switch is crucial for certain tasks. While I'm not yet sure if I will pursue CCIE, if I do, I know that the 30 plus 60 switch is superior to the 50 switch for just a small difference in cost.

To run advanced IP services, I will need licensed iOS products. These are not available for free, but I have been fortunate enough to obtain some from friends who are CCIE certified. Additionally, when purchasing used equipment, I have found that some come with the necessary iOS already installed. If you stick with the same model for your other equipment, you can copy the iOS and get what you need.

I have just enough equipment to complete the lab required for my CCMP certification, but I am not quite ready for it yet. In the meantime, I have been using the CCMP Success Series study guide by Chris Bryant. The guide provides practical knowledge and is an excellent resource for those wanting to learn how to do the job in the real world.

While the CCMP guide will help teach you what you need to know to do the job, you will still need to memorize some things in order to pass the exam. For this, I recommend getting some good practice questions and really going through them. This will help you learn the commands and become proficient at doing the actual work.

It's important to note that the goal is not just to pass the certification exam but to actually be able to do the work in the real world. Many certified individuals lack experience and have simply memorized brain dumps in order to pass the test. To truly stand out and be successful, you need to have practical knowledge and be able to pass a technical interview.

For those pursuing CCNA, you can likely get by with GNS for a lot of the work. However, it's ideal to have at least a couple of layer 2 switches and 3 routers. Building a frame relay is also important, so having at least one router that supports it is recommended.

As I wrap up this blog post, I want to remind you all that having a solid understanding of networking is becoming increasingly important in today's world. With the rise of remote work and the need for businesses to stay connected, having a strong network infrastructure is essential.

I hope that this article has provided some valuable insights into the world of networking and how you can build your own home lab to learn and experiment with different networking technologies. Remember, with the right tools and resources, anyone can become a networking expert.
