Re: static routing [7:51599]
Paul, Take plenty of time to understand the network design prior to making changes. If most all of networks are stub areas connecting to a central site there is no immediate rush to implement dynamic routing protocols. It also depends on the desktop protocols that are in place. For instance some dynamic protocols have features that make IPX easier to route than others. You might also find hidden issues, security, NAT, LAT, and others. Its sort of like...

Zahid, The Boson tests are a great study tool. I recommend reading the material for the study topic, then doing as much hands on as possible on the study material, then use the Boson tests. After taking the Boson test, review the material you are weak in, then retake the Boson until consistently over 90%, then take the exam. They are high quality self-tests and much less expensive than the ones that used to be available for Novell and Microsoft exams (Big Red Self-test, Transcender, Self-test software, etc.) The CCIE Written Boson is especially good.

Re: CCIE Lab Construction [7:9092]
Ken, Congratulations on the equipment. Those are some great pieces. I suggest setting up the 2621's with Enterprise w/FS Plus IPSec. Check memory requirements before loading and compare with your memory/flash installed. With it you can experiment with CBAC, which provides a firewall similar to the PIX. I recommend getting (2) other routers if possible. The 4000's are good buy now with 4 serial port module installed (to use as a frame switch), and a termserver. A 2509/2511 is recommended, but a 508/516 will work as second choice.

Re: CCIE Lab Report - unsuccesful
Chuck, I am surprised that you didn't pass on the first attempt (you're scaring me). But I also think that it is an important part of the process. My first attempt will be in August. Failing the Lab makes us see the value and difficulty of the lab; appreciate the level of expertise required to pass; and the only way this certification can hold its value in the future. You said that you could do everything in the lab, but overlooked some simple things that kept you out of Day 2. It might be something completely different for me, but the Lab is where we find these things out, so we will be detail oriented, and at a consistent level of expertise when passing the lab. Study hard and good luck, Tim - Original Message - From: "Chuck Larrieu" [EMAIL PROTECTED] To: "Cisco Mail List" [EMAIL PROTECTED] Sent: Saturday, April 07, 2001 6:34 PM Subject: CCIE Lab Report - unsuccesful Hey, everyone, how you all been? The short story is I did not make it to day 2. The rest of this is a bit long winded, and easily skipped. First of all, I was quite pleased to find upon reading through my Day 1 scenario that there was nothing I couldn't do, given time. There are plenty of practice labs from several different sources which cover all the core topics, so there were no surprises for me. Secondly, I was quite pleased when during my review of Day 1 results with the proctor, he told me they were going to change the written instruction on a particular section because of the solution I used. I'm actually quite surprised it hasn't been done before. I was grudgingly given points, although I was told my solution was definitely not what they had in mind. However, in the end, it was a few simple omissions that cost me the points I would have needed to squeak into Day 2. Only one of the six of us who began together was invited to the second day. Things I learned: 1) having the core topics down cold is CRUCIAL. No kidding! 2) Time is crucial, but not, I believe, in the way I have seen it discussed in many places. I highly doubt that typing 80 words a minute versus my 20 WPM was the difference. Not when I spent as much time as I did contemplating. You can't think it. You have to know it. By 2:00 p.m. I knew I didn't have a prayer of hitting all the requirements. At that point I started counting points, putting myself in a defensive mode. By quitting time, if I got full credit for everything I thought I deserved, I would have had 31 points. As I found out in my review, I missed a few simple things, and blew myself out of the water. This leads back to the internalization of the core topics. You can't be thinking about how to configure anything. You have to just bang them out, the same way you bang out shaving or washing your hands or eating your lunch. 3) Methodology is crucial. You have to have a good methodology that is internalized and is habitual. You can't be thinking "what's next?" I don't believe it matters what your methodology is, so long as you are consistent and quick. My own methodology failed me because I was constantly adjusting, rather than banging it out. 4) I spent a good two hours last night in my hotel room debriefing myself. I have six pages of notes regarding my day one experience. This will form the basis of my study plan for my second attempt. I know that it is highly unlikely I will have a scenario like the one I just worked on next time through. But I will focus on methodology and speed. 5) Good rapport with the proctor is helpful. I was able to get the information I needed by carefully wording my questions and making sure that my desired result was understood. The proctor is under a bit of stress himself, with so many folks vying for his attention. He may think you are asking something you are not. I made sure that if I was not getting an answer that made sense that I clarified my request, so that the answer was one that helped me understand. I will say also that the test I saw was reasonably clear. The questions I had tended to be the result of outputs from various show and debug commands, to clarify what the expectation was. A few other comments: I was far too aggressive in scheduling my lab date. Should have pushed it out 60 days. Don't be in a hurry. Those without a lot of hands on need to spend several months of several hours a day practicing. No two ways about it. There has been a lot of discussion about the patch panels used in the lab. All I can say is that the panels are clearly labeled. IMHO you have nothing to worry about. That said, I did have to revisit the rack twice, in order to make a cabling change. This was purely the result of a chicken or egg situation, and not due to any difficulty with the rack itself. People with home labs know well the issue with hooking up routers back to back. I sat next to a guy this morning ( a day 1 candidate ) who was getting up every few minutes and going to the back of

If you're not interested you may want to just hit the delete key now. I just thought that I would take a few moments to share my study methodology for the CCIE lab. I've been meaning to do this since I passed the lab on November 15th in San Jose, but I always seem to get sidetracked with all of my newfound free time. This was my first attempt at the lab and I found it to be fairly straight forward. It wasn't as convoluted as I expected and I had seen pretty much everything before. Day 1 The first thing that I did was read through the entire lab TWICE. I realized that I knew how to do everything and went to work on my diagram. I found day one to be very easy and was done by 2 o'clock. I checked and re-checked all of my work and felt very confident in everything that I had done. After that I spent time making sure that ALL of my information was recorded correctly and neatly on my diagram. I felt very confident when I left, but I have to admit as I tried to get some sleep the what if's were creeping in my mind. Day 2 I arrived for Day 2 happy to see the Day 2 binder on my desk and went through the same process of reading the entire lab twice. I realized that I knew exactly what to do on 90% of the lab and may have to browse the cd for the other 10%. Again, I found that there was plenty of time and I had completed everything that I knew how to do by 10:30. I spent the next 30 minutes reviewing the cd and configuring the remaining 10%. I then re-read everything and checked over all of my work and made sure that my diagram was complete. Documentation is very important in the lab not only for troubleshooting, but to ensure that the proctor can see what you were doing. The proctor spends all day at the lab and then has to check your work in the evening or at lunch for day 2. The last thing he wants to do is spend 30 minutes trying to read your diagram. Of course, this is just my opinion. After day 2, I felt real good about my work, but nervous none the less. This made for what seemed like a never ending lunch. Once we arrived back at the facility I was called first and on the way back to the lab I was told that I had made it to troubleshooting and that I had three hours. When I returned to my desk I found the paperwork for troubleshooting and for the first time found out how many points I had. I had gained 70 of the 75 points and only needed 10 of the 25 from troubleshooting. At that point, I knew that I had passed and just needed to knock out the troubleshooting. As I looked around I realized that no one else had progressed from Day 2. I spent about an hour and a half on troubleshooting and felt like I fixed everything so I turned in my sheet. About 5 minutes later, the proctor returned with a yellow sticky note with my number on it. He then asked me if I would erase all of my configs and then I left with a huge grin on my face. I just couldn't believe that all of my studying paid off. I met Chuck Larrieu a few hours later for a victory dinner. I knew that it would be nice to have some company one way or the other and I was glad that it turned out to be for good reasons. Passing the test was very rewarding, but the journey was just as rewarding. It's amazing the amount of material that you learn along the way and the many friends that you make. I have become friends with many people that I may of never met if I wasn't studying for the CCIE. Study Materials I studied the normal books Caslow, Halabi, and Doyle and found them all to be very helpful. I also used three other books extensively that I don't see mentioned very often. I used the configuring cisco routers for bridging, dlsw+, desktop protocols and the Cisco Press Lan Switching Book. I found them both to be very helpful as I work extensively with cisco routers and rarely use cisco switches. I also used the CCIEBootcamp labs which I found to be an excellent resource for practice. There are a lot of other labs, but most of them don't throw everything together like the bootcamp labs. I have to admit that I only completed about half of them and never did the dreaded lab 8, but I studied all 17 of them and read up on anything that I didn't know how to

Re: Why 8 wires in RJ-45?
Where I work, we have many Terminals in use (Memorex/Telex). When the cables for these were punchced down (Years ago), they decided to save money by using 25 pair Cat5 and only punching down one pair for each terminal. Now we are ready to upgrade to IP-based terminals (MTX 1683) and PCs in some areas. All these areas will need most of the cable ran again. Please consider the future and just run all cabling to standards already set.

Hi group members In TP cables we have eight wires. Only four are used. Why we need the other four. The same thing applies to DB-25 and other types of cables. We don't use all of the wires. Why?

Re: DSU/CSU Back-to-back with T1 crossover
I am trying to connect two routers via back-to-back Adtran DSU III AR and an Adtran 56/64 DSU and am not having any luck. I've set the clock to MASTER on the DSU III and set both to 56K, but still get open loop on the DSU III. I made (and tested) the cable with 12-45 crossover, but didn't use other wires (are they required for anything?). I keep getting Open Loop errors on the DSU III, although I've tested the cable. Could it need a different crossed pairs? From reading its manual, it appears to need 12-78 crossed.

Did anybody try this? I will appreciate any help Do it all the time. Gotta love those alarm pairs. 1) did you configure clockrate on the DCE-side of the back-to-back connection? The routers connected to the TSUs will both be DTE. He'll want to set clock on one TSU to "Internal" and the other to "Line" (or maybe they call it "Network"). 2) Did you check your adtran manual for info on putting them back-to-back? My adc/kentrox csu/dsus require a dip switch change to work back-to-back. Really? I've never needed to do that, just set one end to provide clock. Maybe the Kentrox ones use a dipswitch, but the TSU series, IIRC, have a little LCD display and arrow buttons to navigate it. Also check that the number of channels (start and end) is the same on both, typically start at 1, number of channels 24. and that they're both set for the same linecode, framing, and speed. Recommend that you use B8ZS, ESF, 64K. Shouldn't be critical as long as they're both set the same. Note that the Ciscos won't probably be happy with frame encaps on this setup unless you've configured one of them as a frame switch. Try HDLC or PPP. It would be helpful if you could provide more info than "not working" in your message. Things like status light indications on the TSUs, interface status on the routers, etc. would be useful. -- Jay Hennigan - Network Administration - [EMAIL PROTECTED] NetLojix Communications, Inc.

Re: Back-to-Back ISDN
Sorry, no you can't. I thought the same thing at first. I thought that if a router has two serial ports and can emulate a frame switch, then naturally if I bought a Cisco 4000 with an eight port ISDN module, that I could use it as an ISDN switch, but no dice. You need either an ISDN simulator such as Teltone's ISDN demonstrator or the Teltone 2000, OR an ISDN switch such as the Adtran 550 or Adtran 800. Either solution is fairly expensive. I bought the ISDN demonstrator for around $1700.

Re: LINUX ROUTER HELPPPPP
If both interfaces are up and IP forward is on it sounds like you just need to map a router between interfaces. Try ifconfig /? or man ifconfig. Maybe even man ip route. Sounds like you are close. There is a site somewhere that shows how to set up Linux router that fits on a floppy disk. Sorry, can't remember where.

Re: 802.2
The short answer (below) found at: http://www.cisco.com/warp/public/10/wwtraining/demos/ccna-demo/glossary/i.ht m There are much more detailed answers, depending on what you are trying to do, which might be more appropriate. Basically the 802.2 is what makes multi-protocol available on one interface by separating the Data-link layer into two separate sub-layers. Tim IEEE 802.2 IEEE LAN protocol that specifies an implementation of the LLC sublayer of the data link layer. IEEE 802.2 handles errors, framing, flow control, and the network layer (Layer 3) service interface. Used in IEEE 802.3 and IEEE 802.5 LANs.
