Guest LilBambi Posted April 12, 2014 Share Posted April 12, 2014 Yeah, but when you get to use it, it comes back faster than if you never learned it. Not quite as fast as riding a bike, but compared to how long it took to learn it all in the first time, it will feel like it. Quote Link to comment Share on other sites More sharing options...

ross549 Posted April 15, 2014 Author Share Posted April 15, 2014 Well, we just took the CCNA1 subnetting quiz (CIDR only) and I kicked the subnet questions all over the classroom. We have not hit VLSM yet, but I do have a bottle of Ibuprofen handy. Adam 2 Quote Link to comment Share on other sites More sharing options...

V.T. Eric Layton Posted April 15, 2014 Share Posted April 15, 2014 VLSM is not difficult at all. Learning sub-netting itself was more difficult by far. Quote Link to comment Share on other sites More sharing options...

ross549 Posted April 15, 2014 Author Share Posted April 15, 2014 They want to teach us the box method to VLSM. I will bring my colored pencils. I now have a self-given assignment for routing. My instructor seems to think I could not ping a public IP address without a default route built and a static route to the IP in the box. Off to deploy a Debian box. I think I will need to build an Ethernet cable. I think I am out. Adam Quote Link to comment Share on other sites More sharing options...

Guest LilBambi Posted April 16, 2014 Share Posted April 16, 2014 As long as you are painting by numbers you should be be fine. It's when you need DNS for address translation that it gets tricky. Quote Link to comment Share on other sites More sharing options...
ross549 Posted April 16, 2014 Author Share Posted April 16, 2014 So I showed the above to my instructor today, and he said he thought it would be easy enough to do in linux, but he did not think it would work in Windows. Huh? This is a basic TCP/IP function! Why would Windows not have it? *facepalm* Adam Quote Link to comment Share on other sites More sharing options...
Guest LilBambi Posted April 17, 2014 Share Posted April 17, 2014 There are networking things that are SOP in UNIX/Linux and even Mac that are quite different in Windows sock. Oh, and that will soon be true of Mac as well likely as it moves to support the Windows sock more and more sadly. Quote Link to comment Share on other sites More sharing options...

ross549 Posted April 18, 2014 Author Share Posted April 18, 2014 It is another whole language. That language also does not correspond to anything I have used before.

V.T. Eric Layton Posted April 18, 2014 Share Posted April 18, 2014 Yes, it's different. Not too bad, though. Learn it. Live it. Love it. You'll DIE without it when you go to take that exam. Trust me. Quote Link to comment Share on other sites More sharing options...
ross549 Posted April 18, 2014 Author Share Posted April 18, 2014 I know. A question... we are doing CCNA 1 and 2. How far will that get me? Adam Quote Link to comment Share on other sites More sharing options...
V.T. Eric Layton Posted April 19, 2014 Share Posted April 19, 2014 I'm not sure I understand your question? I forget what they're calling it now... it was updated last October, but the tests used to be called ICND1 and ICND2 (ICND = Interconnecting Cisco Networking Devices). ICND1 and successfully passing (82.5%) examination will get you the CCENT certification. ICND2 and successfully passing the examination will get you the full CCNA cert. You can also opt for the combined test... a real nut cracker. ICND1 is heavy on the mechanics of networking: subnetting, VLSM, router and switch setup, Cisco IOS, etc. ICND2 is heavy on routing protocols: EIRGP, RIP 1 & 2, OSPF, etc. Quote Link to comment Share on other sites More sharing options...
V.T. Eric Layton Posted April 19, 2014 Share Posted April 19, 2014 Adam, do they have you doing any lab work yet with sims or with actual Cisco equipment? You need your lab work. That's the only way you'll get comfortable with the Cisco command line and manipulating/troubleshooting the devices. Open that file you downloaded from me the other night and install the Cisco Packet Tracer simulation app. It is a VERY, VERY good way to learn how to design, set-up, and manipulate cisco devices in real time. Have fun! Quote Link to comment Share on other sites More sharing options...
Guest LilBambi Posted April 19, 2014 Share Posted April 19, 2014 @lilbambi - adam had made a statement about windows capabilities, i simply posted a response. Was being facetious. Quote Link to comment Share on other sites More sharing options...
ross549 Posted April 19, 2014 Author Share Posted April 19, 2014 I was tinkering around with building router setups in Packet Tracer last night. We are using version 4.0 of the Cisco Networking Academy. I guess there is CCNA 1-4. I am not sure how ours are related. From what I have been able to decipher, doing parts 1-4 would be needed for a full CCNA, but I am not sure. But I think I am comfortable building a basic 2 subnet router + switch setup, which is what's needed for the practical test on Monday.

ross549 Posted April 19, 2014 Author Share Posted April 19, 2014 Was being facetious. I'm not sure if I responded to temmu's post or not, but I assumed a broken gateway +static route would be doable in Windows.... did not know the syntax, nor did I take the time to look it up. Been sick + studying all week. It does not help that my instructor has no previous experience with big time networking prior to teaching this course. He knows it fairly well, about 90% maybe, but I know I am frustrating him with my barrage of "why?" questions. Adam Quote Link to comment Share on other sites More sharing options...

ross549 Posted April 19, 2014 Author Share Posted April 19, 2014 OK, So here is the document covering the course I am in at the moment. https://www.netacad.com/documents/300010/10046467/CCNA+Routing+and+Switching+-+At+a+Glance/8738e31f-0cc1-4eb4-860e-aa59695dae53 I am doing Introduction to Networks now, and I'd be willing to bet we are starting Routing and Switching Essentials next week. If I am reading the Cisco site correctly, I can take ICND1 and get CCENT certification. Adam Quote Link to comment Share on other sites More sharing options...
V.T. Eric Layton Posted April 19, 2014 Share Posted April 19, 2014 That is correct. ICND1 course and exam = CCENT certification. Quote Link to comment Share on other sites More sharing options...
