DO NOT design your network like this!! // FREE CCNA // EP 6

Thanks to this video my home network is more expensive than my actual home.

This generally isnt a 'Noob Network Engineer' issue, this is generally a budget limitation of a small business.

This guy lives in the corporate mindset, which is how I was educated. When I went into the small business space, it's about keeping costs under control.

Thank you for your excellent vid, as always! Today I passed the CCNA 200-301 exam with a 925 score! The material and resources I found the most useful are, ExamHighPass CCNA 200-301 practice exam. I can confirm that it is valid for 2022. Most of their Q&A shows are at the actual exam.

"How to build a small home business network for $40 Million."

"No one said networking is cheap" Especially when you go cisco.

I've been in the trades for 25 years, 10 of them as a network tech, I've only ever seen two 3 tier networks, one was my local government center. Can't tell you the pride I feel knowing I personally terminated 24 cables to each of the thirteen 911 desks, on top of the hundreds of miles of cable just in the data center. The other was a global company they had two juniper switches similar to the Cisco one you showed. According to the documentation, each chassis was about a hundred grand, as well as each individual routing engine. 6 per chassis, all tolled 1.5 mil just on tier 3. Then there was the 6 racks of tier 2 switches...

As a self-employed man, I am the IT department. I looked at which tier I had set up. It only brought me to tears. 😀

iam using "as long as it work" tier

There's one thing you do that's a cut above most channels - You're excited and enthusiastic about everything you share. I cannot stress how beneficial that has been for myself learning from your videos. You have retained a sense of wonder and it's brilliant. Absolutely stellar.

As support manager for a software company serving the legal community, I got a call one day from a LARGE law firm in midtown Manhattan saying our software was just to slow for them. With a conference coming up in a week or so, the sales manager asked if I could troubleshoot the problem if I was on site. I popped into their office and they showed me their networking closet, with stacks and stacks of HUBS. That was a short visit. As soon as they dumped the hubs for switches, they called to say all was well! (Nearly 25 years ago!)

I just want to point out for smaller networks with a lower budget, you can link multiple access switches between eachother in a full or partial mesh, to achieve redundancy. Before you do that make sure you read up on Spanning tree protocol.

my company's network design has no tier, but this does bring tears in my eyes every now and then

All really good points! One thing I've been challenged with in the past is small business office networks without a full-time IT person. Then you have this trade-off between reliability and simplicity. With growing businesses sometimes they are stuck in-between the SOHO and enterprise models until they get a couple of good contracts to pay for proper IT staff.

So cool to get to this video on my journey. I was working on a Cisco 4510R+E as a hands on technician and although they called it the “core switch” I had no idea what they meant! Getting to this video brings to light how immense their network layout must have been, and now knowing this makes me feel like I’m one step closer to becoming a qualified engineer. Thanks so much Chuck!

OK, so, to get rid of single point of failure: 2 sources of electrical service - two mains companies, or more often, mains + generator 2 data backbones - primary and secondary ISPs. 2 routers on each ISP - primary and backup. (that's 4 routers) 2 main (l3) switches - each connected to all 4 routers. 2 LAN switches - connected to both l3 switches 2 data cables to each drop. And this is where we start getting into ad-nauseum. Spend $15000 setting up a business... $20k for the network. If your business can't take a 10 minute outage without completely failing - you're doing /that/ wrong.

Company I work for is getting super high tech, they've just ordered 30 tin cans and 500ft of string! Enjoying the vids, learning a lot!

This video explained good networking better than any class in college I took. Thanks!

After watching this i finally understood how bad our Network is. Its a 2 tier and theirs a lot of Just switch to switch connections from buildings to buildings Thanks Mate, helped a lot
