Re: Dumb Question [7:74315]
The big difference, for me anyway, is that it is a lot easier to find answers to technical questions about the equipment on Cisco's website. Cisco's website is voluminous and easy to search. Perhaps you can get good info with some sort of Extreme login or from Extreme's technical support folks, but when you are a visiting contractor on site you don't necessarily want to ask the customer for their vendor support login or support contract number just to be able to ask a minor question. (Understatement). You want to be able to find answers to most questions on your own. Others will say that Extreme switches are fast and well-priced. That may be so, but I am a researcher (and writer) at heart, and Cisco's website is the best technical support website I have ever seen.

Re: GuideLine book for CCIE Written [7:73925]
Look into Dennis Laganiere's and Brad Ellis' Study Guide for the CCIE written. I got a deal on it through Amazon.com. "Laganiere" makes a good search term. Check out Dennis Laganiere's website, too. www.laganiere.net I am amazed how much advice he gives away. As someone who is almost finished with a book of advice and learning labs, I can say that the amount of advice he gives away for free convinced me that I could not write a little book with just advice about preparing for the CCIE. Thus, the advice is a small part of my book, and the scenarios and explanations of the scenarios are the major part. Thanks, Doug, for making me work harder.

Re: CCIE Lab Setup [7:73612]
With $1,000 dollars, I would first buy a 4 port frame switch router, perhaps a 2520. I say 2520, not 2521 (Token ring), because the ethernet port on the 2520 allows it to serve as an additional router-- perhaps a "backbone" router that you would connect to using ethernet. $200-$300, if you are lucky. A 4500 with a NP-4T might be even better (but loud!!) This will take perhaps 300 dollars or so. You could add another 4 serial ints and/or a bunch of ethernet ints, and this could definitely serve as a full-fledged lab router as well as a frame switch. If you can find a cheap ISDN simulator (vConsole or Euro ISDN PBX gizmo that only does Basic-Net3 and no spids) for $400-500, you probably ought to buy it, since you already have two ISDN capable routers. Then a 1900 or 2820 switch for $100 to $200 so you have a VLAN-capable switch. If you have enough money left over, you could pick up one more 2501. (Always buy a 2503 or 2514 if you can get it for a little more than a 2501, of course.) It's not a first-rate lab, but it is enough of you to learn a lot of the most difficult lessons. You could go for more routers and no ISDN sim, but ISDN can be such a tricky technology it is worth spending a lot of time on. This is a close call, though.

Re: Keeping my head up [7:71800]
"I can't fail it a second time..." You'd better lose that attitude now. If you really can't fail it a second time, then you had better stop now. I hope you will not give up, though. I just suggest you alter your attitude and expectations. To get the CCIE, you will need to be prepared to try and fail. If you cannot afford to take the written test more than once, you will be under too much pressure when it comes to the expensive Lab exam. Very few people pass that on the first try. There is no shame in failing a Cisco written test these days (not that there ever was). I passed the CCIE Lab on the second attempt and a few months later failed the Cisco Pix Firewall Exam again and again (after having always passed Cisco written tests on the first try.) The Cisco written tests these days are tough, tough, tough. I hope you will continue pursuing your goal. Be prepared to take longer than you would like and when the horse throws you, get right back on. Your idea of doing some lab scenarios in preparation for the written test sounds like a good one, but make sure that you also do a lot more book study of theory and the wide range of technologies that are on the written exam blueprint. If you are uncomfortable with an area, become comfortable with it. Embrace it. It is satisying to get to the point where you actually want questions on subjects that you used to dread.

Re: For Priscilla [7:71462]
Thanks for the eye-opener. I did not know that many of the errors one finds in technical books are introduced in the editorial process. Nor did I know that the publishers are not strong on things like diagrams and cover art. It sounds like I might do better working out the kinks in my Visio diagrams imported into Word, than relying on a publisher to be able to do a better job. I was thinking of using one of my nice-looking Visio diagrams as cover art, perhaps jazzing that one up with color. I don't care about getting an advance up front. If my book of CCIE lab advice and scenarios with detailed explanations (like Hutnik and Saterlee CCIE Lab Practice Kit) is of high quality, it will sell pretty well. The key, for me, is to make sure that it is of high quality. A few errors on crucial points can render an otherwise great technical book untrustworthy. I have caught some errors in my first three scenarios, and will probably find some in the next draft, too. The key to good writing is rewriting, I have been told. The only reason left for submitting a book to a big name publisher is to be able to say "I have a book published by Big Publisher, Inc." For someone without an established name or reputation, that is still something, but your post changes the whole cost/benefit analysis. I will have my hands full correcting my own mistakes, without having to fix the mistakes of editors.

Re: Subinterfaces [7:71421]
Your point about frame map statements and layer 3 addresses brings up and
interesting point. You CAN have a different kind of frame-relay
encapsulation on different PVCs, and you do this with frame relay map
statements.
I don't have time to test it now, but I remember learning that to use frame
relay IP TCP header compression, you have to use the proprietary Cisco frame
relay encapsulation. So if you want to use frame relay IP TCP header
compression or RTP header compression on a PVC, you configure compression
using a frame map statement and that PVC then uses Cisco FR encaps (I think
it is automatically transformed into a cisco FR encaps PVC).
Similarly, if you have frame relay IP TCP header compression on the physical
interface, you can turn off compression on a per-PVC basis using your frame
map statements ("nocompress" comes at the end).
So, you CAN have different encapsulations on a per PVC, sort of. I think
all this business of cisco encapsulation working on a PVC when the
interface is set to ietf (and the frame relay switch is configured for ietf)
works because the FR switch doesn't really care what kind of FR
encapsulation is used on each PVC, while it does care a lot about the
lmi-type. The remote router needs to be set to the correct kind of FR
encapsulation, though (but, again, this can be set per PVC.)
Please feel free to correct me if I am wrong in any particular. I would
hate to have misremembered all or some of this.

Re: RE: NOOOO!!!! [7:70103]
This reminds me of the sort of swapping that is a solution to the problem of upgrading IOS on a 2500-series router without the newer bootroms. You upgrade the IOS in a 2500 with the good bootroms, and then swap the flash sticks with the router that lacks the proper bootroms. The sort of common sense that permitted you to think of a solution like this on your own is often more valuable than genius.

Re: CCIE Vs. Linux engineer (not Ph.d) [7:66669]
You have to think about what you want to do, and about the long term. While the rest of the economy experienced a mild and short recession-- so mild that it is debatable whether it technically should have counted as a recession, the telecommunications sector experienced something much more serious. If I use the word "depression," someone will say that is not accurate, as you can't have a depression in one industry, or some such technicality. This condition will not last forever. No one is throwing away their computer and giving up internet access. We are moving toward more and more high speed internet access and wireless access, which means more business and more support work. Cisco has just bought Linksys, a consumer networking equip company, which suggests that Cisco may soon move heavily into the mass market arena. As lower-cost Cisco consumer and SOHO devices proliferate, perhaps the trend will be for there to be a growing number of Cisco-related jobs, but at lower pay than we saw in the tech boom. I think the long-term future for people near the top of the Cisco knowledgebase pyramid is very good. Someone will have to teach all these lower-level support folks, and write books on how to use such and such Cisco consumer router or switch or firewall, in addition to doing all the corporate network design/install/troubleshooting work done now. Linux is very difficult to learn really well. True, CCIE lab equipment is expensive, but I think it may take less time for some people to become a CCIE than to get the kind of facility with Linux that the Linux-guru jobs require. Okay, maybe this is going to be true for only a very few people, but it might have been true for me. I mean, the UNIX command line syntax (-this, /that) often bears no relation to anything that can be used a mnemonic, while Cisco IOS is very much like plain English. I know I made a conscious decision to put away my various Unix platforms (FREEBSD, Red Hat Linux, Solaris) and concentrate on CCIE. Anyway, I love the Cisco material I am immersed in now. You will need to decide for yourself what you want to do, but if you decide based on the relative salaries offered right now, you could make the wrong decision.

Re: Speed Duplex Talk again [7:66402]
I don't think we can stress enough how important the speed/duplex mismatch and autonegotiation problems are. If you are having a LAN problem, this is one of the first things you should consider. The interesting thing thing about duplex mismatch errors is that things can seem like they are working okay, but you notice problems once in a while. Every day, probably hundreds of thousands of users and servers are experiencing less-than-optimal performance because of this kind of problem. Are some or all of your IP phones rebooting every once in a while? Even this could have something to do with a duplex mismatch problem somewhere between your IP phones and your Call Manager. One question I have for folks is is whether duplex mismatch errors between a switch and one device on a segment (network printer, PC, server, etc.) could substantially degrade performance on the switch so that other links would be impacted in a noticeable way.

Re: CCIE Practice Labs - Redustribution Strategies [7:66306]
This may not always be an option, but I would use tagging and route-maps instead of distribute-lists any time I can. There is just too much room for serious, show-stopping errors, with distribute-lists. With route tagging, you could mess up and end up with a packet taking a suboptimal path to a destination, and you could lose some points, but the packet will get to its destination and whatever was riding on this will probably work. But that's just me working around my natural absent-mindedness-- taking as a given that I will screw up the distribute lists.

Re: OSPF Hellos on ATM interface Disappear [7:66096]
This sounds like a problem that was discussed here (or on the groupstudy ccielab list) in the last few days. The problem then was EIGRP over ATM. Now it's OSPF over ATM. Try specifying your OSPF neighbors manually, so unicasting occurs. There may be a better solution, but try this until someone chimes in with something better.

Re: CCIE written R&S [7:65972]
I think Dennis Laganiere's own CCIE prep book is very good. He is too polite to mention it here himself, but I think people should know about it. I like how it covers a vast array of topics in a summary fashion, but goes into considerable depth when it comes to especially difficult topics that cry out for in-depth coverage (like RIFs). It is a great way to cover the material for this particular exam. I bought it recently from Amazon for 30-some dollars to assess its usefulness for early stage CCIE preparation. It is worth more than it costs, in my opinion.

Money is helpful, but the only power I want is some power over my own destiny, which is asking quite a lot as it is. With the CCIE, it sometimes possible to find a job that involves studying network technologies, experimenting with cool equipment in the lab, teaching other folks what you have learned, consulting with folks about network issues, doing some installation work, some troubleshooting work, and talking to prospective customers about neat cutting edge network security devices. It is pretty fun work, and most of the time (in my company, anyway) it involves considerably less stress and pressure than some of the more high-flying corporate jobs that nrf is thinking of. I am not saying that this is the experience of anyone else, but it is my life now. I love it, and learning what I needed to learn to pass the CCIE lab made it possible.

Re: CCIE Vs. BS or MS degree [7:59481]
While Mr. Ladrach is almost certainly correct in his statement that the CCIE is less challenging that physics and calculus, he might be able to speak more authoritatively once he has passed the Lab Exam. As for being easier than accounting and economics classes, if you are reasonably intelligent and do all the homework, you will almost certainly pass most accounting and economics classes. You can be reasonably intelligent, do all the right things in preparation for the CCIE lab, and fail and fail and fail again. While I would certainly say that the CCIE material is less difficult to learn than some other subjects I have studied, I can honestly say that I have never studied so hard for one test in my life, or gotten myself into a state where I had such an "edge"-- a certain sharpness and facility with a given subject matter that I fear I may never experience again (unless I go for a second CCIE). It is not rocket science, but you have to execute VERY well. As for nrf, - his contributions to groupstudy have been almost entirely negative. While it is helpful to have some discussion of things like the job market and the question of whether it is better to invest time and effort in a degree versus certification is useful, constantly chiming in with negative thoughts and assessments is not very helpful. This is something of a support group, and in these difficult times, those of us who have already set out to achieve certification goals need encouragement and technical advice. I do not know if nrf is one of these people (he could just be negative for no particular reason), there are some people who come to these discussion groups to discourage others from pursuing dreams the achievement of which might bring about a greater number of certified IT professionals and perhaps exert downward pressure on salaries. For the record, I studied and practiced hard, and passed the CCIE lab with precious little "industry experience." I found a great job in a great company within two months of passing the CCIE Lab, and I had a few other interested folks contact me for interviews. I certainly cannot make any promises about the future, but my point is that if you can get all the way to passing the CCIE lab, you will probably not regret it. This journey is worthwhile, and don't let a bunch of naysayers get you down. That said, if you are very young and considering certification as an alternative to a college degree, understand that the college degree (even a BA) and what you should learn in the process of gaining it, can be very helpful.

Re: Would this break the NDA [7:55799]
Your policy is definitely the safest. The stakes are pretty high, and if you ask, and Cisco refuses to answer, then you will know that it is not something to discuss on this list. Some may disagree with the policy, but Cisco is in the driver's seat on its NDA policy, and it is not worth risking losing so much just to tilt at windmills.

Re: good alt. to a catalyst 3550 [7:55132]
The Cat 3550 is currently a new product so used items are hard to find. However, if you are not too far along in your CCIE preparation, you have some time. The fact that this question was not posted to the CCIELAB mailing list suggests that you may not be in a huge hurry yet. Many of the important lessons that you need to learn can be learned with a relatively cheap lab of Cisco 2500-series routers. No voice, no switch (except perhaps some really cheap switch), no ATM. Many of the hardest lessons to learn involve matters such as routing protocols and redistribution among routing protocols, as well as countless router IOS features -- which can be learned in a cheap lab. After 6 mos to 1 year, you may find that 3550s are available used from CCIEs who went before you. Yes, this means that for many months you may need to use lab scenarios that do not take advantage of the cutting edge features of the 3550s, or you will need to adapt scenarios to your topology. This is not optimal, but a lot of us have had to do this with other technologies (taking the ATM link out of a scenario, not doing the voice part, doing token ring with MAUs instead of the formerly-expensive TR switch).

Re: Extended Vlan across Wan [7:54866]
I think some people tend to be intimidated by ATM more than by frame relay because it is more expensive to get into a home lab and most of us are less likely to have a job configuring ATM on a regular basis than configuring frame relay on a regular basis. Yes, I know you can get ATM in your lab with 7000s and a non-Cisco switch at an almost-reasonable price, but it's still a bit much too much money, bulk and noise and power consumption.

Re: Please Please help!!! [7:53917]
You can use an NM-4A/S, but these ports can go no faster that 128kbps. This will also use up your NM slot, which you may want to leave open for something else (like a Voice module). Shop around for these NM-4A/S modules, as the prices vary drastically from vendor to vendor, and day to day on ebay and the ISP-equipment list. I sold mine already.

Re: Off Topic - Quietest Cisco Switch [7:53800]
I can narrow down the field by telling you that my Catalyst 2828-EN (2820 series-- modular brother of the 1900-series) is NOT quiet. Mine makes so much noise I avoided using it (and my Cat 5000), and used a combination of quieter 3Com switch, 3Com hub, and crossover cables. This was a mistake and prevented me from getting lots and lots of practice carving out VLANs on switches early on in my preparation.

(probably not original power cord, though, as they are generally fungible) $1,200 plus $15 flat shipping for FEDEX 2nd Day Shipping to continental US. 2x NM-1V plus 2x VIC-2FXS. Original owner and original packaging, anti-static wrist strap, manuals. $1,200 for all plus $20 flat shipping for Fedex Ground (will probably be two separate parcels). Cisco 2621 router loaded with 64 megs RAM and 16 megs Flash, a WIC-1T, and a WIC-1BU. No plastic face plate. Comes with rack mount ears. Look at commercial practice labs and see how useful this particular configuration is. $1,350 plus $10 flat shipping for FEDEX Ground. Package of TWO (2) routers for one good price: Cisco 2610 router loaded with 48 megs RAM, 16 megs flash, a WIC-1T, and a WIC-1BU. No blank plate for the NM slot. A very useful configuration. PLUS a Cisco 2501 Ethernet router with 16 megs Flash and 16 megs RAM. The 2610 comes with rackmount ears. The 2500 comes with an AUI-10BT transceiver. $900 for both plus $15 flat shipping (for both together) for Fedex Ground to Continental US. Cisco 2613 router with 48 megs RAM, and 16 megs Flash, and an included NM-4A/S with handle (so it can serve as a frame switch, but it would be kind of expensive to use it just for that all the time). Token ring router, unfortunately, but it holds network modules just as well as any other 2600 series (BTW, be careful that you check out which NMs can go in a 2600. Some only go in 3600s.). Also comes with rackmount ears. Missing one small filler plate where a WIC goes. $645 plus $10 flat shipping shipping for Fedex Ground to Continental US. Cisco 2514 dual ethernet router with 16 megs Flash and 16 megs RAM. $350 plus $10 flat shipping for FEDEX GROUND to continental US.

Re: ISDN Simulator.... [7:50405]
Someone just asked me ISDN simulators, and told me that the price of the one they were thinking of buying, an Emutel, had dropped 500 dollars. I have a Teltone ISDN Demonstrator, and I like it fine, but I would look into the Emutel if its price has fallen so much. You don't need NT1s for the one he is looking at. The Emutel is British, I think, and the folks in Europe don't use NT1s, I gather. They get to connect to S/T interfaces, so their ISDN simulators tend to use S/T interfaces. The Emutel may have U interfaces, too, for all I know, which would be good to have in case you get routers that already have NT1s built in.

Re: CCIE Home Lab [7:49369]
DO NOT buy a Cat 5500 for the home lab if you are doing so for the CCIE. They are taking the 5500 off the Lab. Read the list about these and other recent changes. They were announced less than a month ago, and there has been a lot of discussion here. Now you could still buy a Cat 5500; just don't do it because you think it will be on the CCIE lab. They are dropping in value daily, so you might be able to learn something for CCNP switching test on a very cheap Cat 5000. My Cat that I was proud to have put together at reasonable price will go someday for MUCH less than I paid for it. Also, do not even think of buying a 3900 TR switch.

Re: Lab coming Frakin' out here [7:47055]
Do not take it so soon if this is where you are. You can still cancel. If you have not paid yet, don't. If you have, then switch to a MUCH later date. You need to get deep into this stuff. You will have questions once you have delved into the practice labs, and you will need to go back and do more and more reading. More practice. More reading. More practice. More reading. Unless you have money to burn. I am taking the Lab Exam for the first time next month, and I am only now feeling like I might have a decent chance of passing, after three more weeks of hard work. I passed the written last August, and have moved my date back more than once. If you had already paid and it was less than a month away, then my advice would be different.

Re: Not only is TR going... [7:46391]
I don't think Cisco is primarily concerned with the "cost" of outfitting their own labs with 6500s. After all, their cost is MUCH lower than the list prices. I think Cisco is being considerate of OUR wallets. This is the same reason they don't have 7200 routers and 7500 routers on the equipment list. These are used widely in the "real world," but Cisco wants us to be able to learn the material without having access to a $50,000 lab (used prices).

Re: Logic and "Lab Rats" [7:44653]
I thought the "experience versus certification" debate had finally died a few days ago, but now it resurfaces over on the professional list. I may as well weigh in. The problem here is clear. Some folks with lots of experience are scared (or merely offended) that some manager or client might think some relative newbie with great-sounding certs is as good or better (or even nearly as good) as the more experienced folks. Many of these experienced people gained their experience in difficult or underpaid conditions. The last thing they want is some ambitious upstart invaders studying hard in the lab, then walking into their field and being treated as their peers. The "experience is everything" crowd should relax right now, because in this economy, they are in the driver's seat. One the other hand, the lab rats, myself included, are justifiably scared. We knew that if by studying hard we managed to reach a higher position than our experience alone would justify, we might face some hostility from those with lots of experience. Now, however, we are given to understand that for employers right now, experience is king, since there are plenty of folks with lots of experience and good certs to fill all positions that HAVE to be filled (as opposed to those positions that employers advertise but are in no hurry to fill). Then, there's the common complaint that, "I'm always having to fix the networks screwed up by the paper-CCNAs, paper-MCSEs, Lab Rats, etc."I have enough experience to know that plenty of the screwing-up of networks is done by folks with lots of experience. It doesn't take long in the field to run across an arrogant but extremely experienced guy who thinks he is the only person in his company who knows anything, and then proceeds to break things that he then cannot fix. A little humility is called for in a field where almost no one can know everything and where most of the greatest gurus make glaring errors. Best regards, Tom Larus "Howard C.

Re: how to build a pix firewall out of a PC box. [7:18335]
The home-built Pix strikes me as being more trouble and expense than it is worth. I read about someone who made one, and he had to use an expensive flash card that cost nearly as much as a base-model Pix. The home-built Pix has certain obvious legal deficiencies, and, it is safe to say, could never be resold to someone who might want to run it in a production network. I'm probably missing something here, but if anyone wants a Pix, there are some shockingly cheap base models that people can buy new from a Cisco reseller (around 400-600 dollars, I seem to remember). I imagine these may lack some functionality that the more expensive Pixes might have, but at least people wouldn't have to go on to bulletin boards asking for license/code numbers to use to make their firewall work. And selling your real Pix or using it a production network would be a possibility. If you want to build a firewall for the fun of building a firewall, it makes more sense to go the Linux/Unix route. Of course, I'm working on R&S, not Security, so there may be some great advantage to these homebuilt Pixes (over the retail Cisco Pix base models) that I am unaware of.

Re: CCIE [7:40568]
To Siva, and hundreds of similarly situated folks: I don't know you, but if you are like a lot of us, you will find that you will need more time to prepare for the lab than from now until June, and want to save you the hassle of trying to reschedule on short notice. Okay, that will be easy for you, because you are in Sydney, where lab dates are always plentiful. It won't be so easy for many of those others in the same boat, though. If you are already the king of Cisco knowledge, the guru that everyone in Worldcom/UUNET or IBM Global Network Solutions, or a similar outfit look to for guidance on the details of Cisco networking, and you are just getting the CCIE to put icing on the cake then go ahead and schedule the exam for June. Most of us are not that guru, and we still have a lot to learn. Even the folks with many years of high-level industry experience (I am NOT one of them, by the way), find that there are huge swaths of difficult CCIE material that they have never dealt with in their work. Someone at an ISP may be a guru on BGP, but may have never had to do anything with DLSW+. Conversely, someone in an IBM Mainframe data center may be the guru of DLSW+, but may have never touched BGP, EIGRP, or otehr important Cisco topics. Many people have never configured VOIP, or VOFR, or ATM in their day job. Only a few have ever done anything with a 3920 token ring switch in their day job. The 3920 is not that tough to learn about, but it will take at least few hours on a rental rack to get comfortable with.

Re: Are all the Cisco jobs for CCIEs? [7:40328]
Yous just answered your own question (the tech economy is bad-- very bad), and many people face or have faced the same "chicken and egg" problem. I have often wondered the same thing, about there being almost no ads for junior network engineers, and very few for midl-levels, even. I can speculate about the possible answers, but I not the old pro, so I could wrong. I am convinced that almost no one advertises for junior network engineer positions. They advertise for seniors and then hire the juniors from some of the folks who applied for the senior positions with too little experience. Perhaps they go to some local provider of contract labor (like Teksystems in our area), and hire contract folks who may not even accrue vaction time until they are hired permanently.

Re: Job chuckle [7:27248]
This sort of job posting is extremely common here in the US. The
"CCNA/CCIE" thrown together as if they were all in the same league.
Do the tech managers not know that there is a huge difference, or is job ad
written up by some non-techie who had no idea of teh difference. If the
managers are actually writing up these ads, then it is pretty scary, and one
of two things is happening. 1) They don't know the difference between CCNA
and CCIE, and they haven't a clue about what the CCNP is, or 2) they really
don't give a darn about certifications, anyway.
The second possibility may be more correct than I would like it to be, since
I also notice a lot of ads that make the other qualifications mandatory ("at
least 12 years experience yada yada yada", but certifications "would be
helpful."

Re: quick response (help) please [7:24238]
I could be wrong here, but I would imagine the reason this works is that you have a supernet there, with the mask of 255.255.248.0, so the hosts address is not all-ones, so is not treated as a broadcast address. The host address includes 3 binary digits from the third octet (125), so it works out to be 101 . I guess that zero saves it from being a broadacst address. Is this right, or did the Cable ISP just screw up?

Re: over 1700 passing ccie written every month [7:23680]
I wouldn't worry too much about the raw numbers. A lot of these supposed 1700 a month are VERY good at memorization, and have not touched routers and switches for more than 10 or 12 hours altogether. I have trouble believing the number is quite that high, because the lab dates do not seem to be getting booked up anywhere near that fast. People haven't a prayer of passing the CCIE Lab until they get many hundreds or perhaps a thousand or two thousand hours of work configuring routers and switches. It is a long road, and I am still a long way from getting to the CCIE Lab milestone myself, but the journey itself is very satisfying.

Re: How to upgrade the IOS of C2521?! [7:23498]
Put a cheap token ring card in a PC, and get a nice token ring mau and some IBM Type 1 cables (the thick cables with huge, ugly hermaphrodite plugs. Connect the PC to the MAU and connect the 2521's toke ring port to the MAU. I say to use the TR capability of your router because it is a shame to let a perfectly good token ring port go to waste. If you are like just about everyone else on this list, you will eventually want to at least try for the CCIE, and token ring is crucial to learn. I suggest IBM TR stuff because that is the equipment that finally allowed me to make token ring work reliably. I had problems with RJ-45 MAUs, but IBM stuff worked correctly from the get-go. And it is cheaper than dirt. Once you have your TR connection from router to PC running TFTP server (downloadable from Cisco), type "copy tftp flash", and the router will take it from there. Someone else can tell you how to use the console port to upgrade the IOS. I strongly recommend buying extremely cheap TR equipment and trying TR. I hated token ring before I bought my cheap IBM TR gear, but I love Token Ring now, and I am studying for my CCIE lab exam, so it's a good thing I love it now.

Re: 6509 monetary value and SMARTNET on USED equip covered [7:23507]
I have the same question about Smartnet. If equipment is currently covered by smartnet, and you buy it, can you buy a replacement smartnet contract in your own name. I understand that the original smartnet contract belongs to the original owner, but I am wondering whether you can take out a new one on the equipment.. As for software licenses, if you buy a router that was licensed for Enterprise IOS, does the license stay with the former owner, or go with the router? In this age of dying dotcoms with first-rate, almost new equipment, it would be a shame if Cisco set up the contracts so that almost-new equipment becomes worthless in the hands of anyone but the original owners, but that could be how it works. Please reply to the group, because I'll bet lots of other people would like to know the answers to these questions.

Re: IP unnumbered [7:21794]
Let's say you want to run frame relay or hdlc using serial interfaces on two routers, but don't have any ip addresses to waste, you can use the ip addresses of the ethernet or token ring interfaces as the ip addresses for your serial interfaces. This stuff is easy to look up on Cisco's web site. so check for configs there. A simple example would be something like: int s0 ip unnumbered e0 You are telling the router to use e0's address for the serial link. Now one would think that this would not work, because the ethernet interfaces on two routers usually will not have ip addresses in the same subnet (unless you are set them up on the same subnet in a practice lab). Somehow it all works, though. I need to play with it some more. I used ip unnumbered when I was trying to get ip ospf demand-circuit to work where the isdn link was a backup to a frame relay link. (Yes, this is apparently similar to a notorious ccbootcamp lab, but I didn't know that until I started noticing people posting to the lab list answers to questions I was having.)

Re: Exams sequence [7:21628]
There is absolutely no requirement to pass in any order. Most people will tell you to take troubleshooting last, and I would agree. The reason is that the experience with routers and switches that you should gain in pursuing the other tests should serve you well in troubleshooting. Do NOT try to pass the CCNP tests using books alone. While it is possible for some people to do it, it is not a very good way to learn this material. It's like learning surgery without ever even touching a cadaver. I think taking switching first is a fine idea, and a friend of mine has done just that. Spend a lot of time studying for Routing, for it is very intellectually challenging material and is the most important material you will study, in my opinion. I did not spend enough time on it, and now I am having to work harder as I study for the Lab.

Re: Problem connecting 2 routers w/ATM OC3 int back to back [7:20062]
I think this would involve making sure that you plug the TX (SC or ST) plug into the OC3 interface's RX jack (SC or ST) opening, and vice-versa. I can't afford ATM for my lab, but I remember thinking it was neat that you could do some basic ATM stuff without the switch. If you are asking for some guidance at a more advanced level than this basic cabling level, then forgive my post.

Re: Is loading IOS into 2500 with no Flash possible? [7:14375]
I believe the 2500 series runs at least partly from flash (as opposed to routers that move their entire IOS from flash into RAM and run it from RAM), so you should NOT be able to run a 2500 series router without any flash.
