Re: ccbootcamp part 2 [7:29682]
Developing effective methods for knowledge transfer requires creativity, skill, time, money, awareness of the audience and their learning styles, and other resources. The results may be proprietary and there's nothing wrong with charging for them. I can't comment on the pricing. (Setting a good price has always seemed like a black art to me, having only taken one business/marketing type class in my life.) It does seem like different prices for different countries makes sense, as others have said. A copy of your book graces my bookshelf (I have to admit that I have not had a chance to read it yet). I do not mind paying for the book. There are a number of people here financing their own CCIE, it would be nice if the labs were available in parts (I would be interested in labs 1-10 for example). The labs are extensive (having seen Lab 1 as an example) but are they really worth $650. After having sold 100/1000/2000 lab sets, it becomes less and less clear to me why the $650 fee is warranted. For $650 I can buy about 10 books that help me prep for my CCIE. Are the works of Doyle, Halabi, Caslow, Lee et all now worth as much. I don't believe that each lab takes more work that a book such as yours or Halabi's, the $650 fee may have been appropriate during the boom but I do not believe that such a fee is still reasonable.

Re: cannot ping loopback IP addresses [7:29345]
How are your loopbacks learning about one another? You will want to redistribute the information about your loopbacks into a routing protocol or use static routes.

Juniper has some excellent engineers, and a good product, I don't mean to detract from that. But this list should be more focused on giving people inspiration and not trying to disappoint them by saying that there is no demand for the CCIE when their patently is. I'd like to add one more thing. When did this job start being about just money. I guess I can't speak for everyone. I'm young, single, no mortgage, no mouths to feed. I am willing to travel (having to spend 6 weeks in Barbados or somewhere nice and sunny) is something I am willing to tolerate. People also have to start looking at enhancing their soft skills. Take a basket weaving course. Take a public speaking course. I've been told by many that they can't get over how outgoing I am. A techie with a personality is something that many employers seek. People really need to stop on relying on four letter words to get them a job. A CCIE no longer guarantees one a job. The right person with the right Cert can always find a job.

Re: is it really bad market for ccie ? NO! NO! NO! [7:24336]
feel the need to do (what's up with that attitude anyway? It's almost like some people think I'm somehow insulting their religion, and since when did Cisco become a religion?). Our IOS who art in router Hallowed be thy CLI :) * Yes you are correct to say that that there is no such thing as basic Juniper or beginning Juniper. Such a thing is indeed an oxymoron due to the nature of Juniper's targeted market. So let me revise me argument This is likely to change. I've heard rumors that Juniper will start to get into a midrange market. I don't believe they can survive in the core alone. slightly and say that my argument only applies to intermediate and expert-level skills. For networking newbies, the CCNA, I concede is the only reasonable game in town. But for intermediate level people, I believe that now you can start comparing Juniper and, say the CCNP, to a reasonable degree. It is my gut feeling that the ratio is indeed somwhere around 330:1 for CCNP's to JNCNP's (if such a thing existed). Now it is true that I do not have any hard numbers to back that up (and nobody has any hard numbers that disprove it), but I appeal to the fact that the CCNP is fairly well-known, and has already attained semi-paper-cert status, in the sense Paper CCXX have been created by employers. I have a fair bit if experience under my belt but no cert as of yet (I'm working on my CCNA and CCNP simultaneusly, I've taken some Boson's lately and I do better on the CCNP that the CCNA :( . If employers wanted experience and personality, the certs would not be as regarded as they are today. Anything under a CCIE is just a piece of paper. If employers were looking for employees and not pieces of paper, less certs would be needed. I want my cert to prove competnecy, I do not want it to be used as a hiring decision. I want the employer to hire ME !. that CCNP braindumps are out there and pretty easy to find. This therefore means there is a great deal of extra competition for the real CCNP's' (the ones who can back up their cert with actual experience). Whereas it is much more difficult to fake your way around the Juniper world, such that anybody who has even 1 year of Juniper experience does in fact know a fairly good amount, under the notion that if he was true dummy, he would never be allowed the chance to touch any Juniper stuff in the first place. It is If we handled certs like drivers licenses, we would have a lot less CCNPs today. There should be a practical componenet to the CCNP as well. And such tests should be taken at a minimum 6 months after the CCNP written components. These certs are not memerizaion drills (at least not for me). I refuse to cram for a cert (yeah there is a little cramming over little details before tests). I want to understand something such that I don;t need to cram. I want to have enough hands on experience to make it a breeze to go and write a test. the extra competition, in the Cisco world, of paper-certs and people who are only lab rats and no practical experience, that is what really screws things up for the Cisco people. Juniper doesn't suffer from this problem (at least, not yet). There are 20 or so JNCIEs in the world. 50-99% are likely to be Juniper employees. We really have to get over what the paper says and start taking a look at the employee more and more. Employers may love certs because they are under the impression that it will save them time in the hiring process. They are trusting that the cert is able to assertain the skills of their employee. Certs become useless not because of paper certs but because of employers that fail to take the effor to see the person behing them. * Competition.Anybody who reads my arguments carefully will see that my entire thesis rests on the notion of competition - the fact that there is substantially more competition for every Cisco job opening than there is for a Juniper job. For example, I appeal to the cashier vs. lawyer argument. I would disagree. There are a lot less qualified people to maintain Juniper equipment. If there are only 3000 people in the world that have touched the equipment (I think that number may even be quite overstated), and there are 100 jobs out there for them, there is a lot less competition for Juniper jobs. Untill Juniper gets more penetration in the market , its certs are not as worthwhile as are Cisco's. As I stated above, many of those JNCIEs will be Juniper employees or employees of their largest partners/contractors. These are not individuals on the open market. Clearly there is more demand for cashiers than lawyers, because how many times do you buy something vs. how many times do you sue somebody? But does Um.. In the USA :) Lawsuits are just about as common as purchases :) Here in Canada, there is a very different stance on lawsuits (but thats another story). it then follow that cashiers are paid better than lawyers? Of course
Re: Re: Subject: Re: quick response (help) please [7:24238]
The date is Sept 12 , 2001 , the first few lines of the page :) if the Bates Report is any indication, the trend is actually towards more fragmentation of the former class A space. ARIN has been allocating out of 64, 65, 66, blocks, for example. Those in turn have been doled out to various ISP's and other organizations as something longer than /8 - usually /16 or even longer, from what I can tell on quick notice. I believe RIPE recently opened up the 80 block. I seem to recall APNIC recently announcing opening of the 210/8 or 218/8 block. Saw it on NANOG a few weeks back, I think. In other words, for public IP space, I don't think anyone other than the registries themselves have title to more than one /8 address block. Which would therefore render the argument of supernetting /8's as moot. I suppose someone could do something like that in the 10 space, but one has to wonder why?

While it is possible to supernet class A addresses, it is generally impractical for the most part, unless the ISP/AS that is summarizing two Class A addresses owns both address spaces (and they are contiguous). I might suspect that somebody such as UUNet or AOL or Sprint might do it, but checking the ARIN registry and IANA, I cannot readily find any of them with contiguous netblocks in the Class A address space for ISP use. There are a few, but I would expect those that exist to get returned back to IANA for reassignment (watch wrap): http://www.iana.org/assignments/ipv4-address-space Class B and Class C address space is an entirely different matter w.r.t supernetting.

Re: Passed CIT today!-sniffer skills [7:24131]
I really do not agree with this at all. Learning to use the sniffer.. any sniffer, is at the basic level.. easy. Learning how to filter the rush of data and get something meaningful out of it all is half skill and half black magic ;) It takes a certain level of experience AND skill to put together a decode filter by using signatures and boolean functions that is not taught in very many places. And when you are dealing with viruses, napsterlike clones, badly behaved apps and so on, it's not just knowning the TCP stack.. it's knowing how that packet is contructed, why it is contructed that way, why is it doing what it does and how is it doing what it does. But how does this have to do with sniffer. The sniffer is my eye on the network. Understanding how a protocol works is the most important. Learning fancy filtering can help but knowing the protocol is most important. I also personally know several engineers while good on routers and spouting the OSI layers, TCP layers, etc.. are pretty useless on a sniffer for extended troubleshooting. I really have to disagree. One of the funniest(saddest) claims I have ever heard is someone claiming, on a resume knowledge of the OSI stack where what they should have said I know the names of the layers. Protocol understanding comes first, being able to do something with it is just a matter or training. I'd rather have a protocol expert and teach them how to use a sniffer than vice versa.

Re: over 1700 passing ccie written every month [7:23680]
I wholeheartedly agree. I'm just starting out in the industry and having seen some CCIE practice questions, I wonder why this is such an accomplishment for some. The written is not that much harder than the CCNP tests (someone with a few weeks and good books on their hands can pass the written). Lets remember that there are less than 7000 CCIEs worldwide. 1700 people may pass the written , but its unlikely that more than 2-3 % take or pass the written within one year. Thomas Larus wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]... 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: ADSL/BVI problems solved! [7:23631]
After much experimentation and much frustration, I finally solved the problem with my BVI interface. It turns out that removing the default route pointing at the BVI1 interface and replacing it with a default route pointing at the next-hop IP address fixed the problem. How does your router know where to route traffic ? The default route was pointing to x.x.x.26 (when the traffic got there, it knew not where to go). At the next hop, whatever device was there, used its routing table to forward traffic further. I'm not totally clear on why this made a difference, but it did. As soon as that change was made, I could reach the IP assigned to the BVI interface from hosts out in the world, and general connectivity was enabled. Wild. Routing, its a beautiful thing :) If someone can explain to me why a next-hop static route vs an interface static route made a difference, I'd appreciate it. .26 did not have a routing table (it was you). Had .26 been another router on the network, it would have worked fine. BTW (what was the next hop , .25 ?)

I know I can get the DRAM from Crucial at a very good price but the Flash seems hard to find. I do not care if this memory is Cisco certified or not.

Re: Cisco and DSL + OT DSL question [7:14275]
With DSL being very popular and Cisco having changed their CCNA/CCNP exams not too long ago - why isn't there anything about DSl on the exams at all? A good number of the Cisco DSL gear out there does not use IOS Cisco 67X Series Routers (CLI OS called CBOS) NI-1 DSLAMS (GUI Only) Only recentely announced modems/routers as well as NI-2 DSLAMS offer IOS capabilities. There is also very little that is DSL specific. The now defunct CLEC that I worked for used Cisco DSL gear. Other than the modems/router (67X series CPE) and the DSLAMS, the rest of the equipment was just standard Cisco gear with ATM interfaces. I know that DSL is still not considered as reliable as dedicated lines, frame relay, etc., but for SOHO users, it is perfect when available and when the provider is not going belly up within 4 months. DSL's statbility is based on the copper in the ground as well as the carrier. I had customers up for months without any service problem whatsover. However, I do not understand the technique behind DSL yet, so I am not sure what's going on. The DSL router is connected to my phoneline, and it has an ATM led on the front. Does that mean it actually works on an ATM network? It appears as if your carrier uses PPPoATM. To answer your question, yes, you data is likley hauled back to a router or termination device (VIA the DSLAM) in ATM cells. Also, Since I have the router on a public IP address, why is it not configured to give me a private address for my LAN (the cable that goes from the router to the NIC in my PC) instead of another public IP address? The router may be configured in Bridging Mode (RFC1483). Instead of the modem/router having the IP assigned by the ISP, it is assigned to your NIC. If you have a 67X series router, that device is capable of acting as a modem (instead of a bridge if you use rfc1483 bridging) And last, what about the EnterNet and PPPoE, what exactly is that, and couldn't I use something else? PPPoE is in part an authentication scheme, as well as an encapsulation scheme.

Doyle's TCP/IP Volume II is available at my local Chapters. As is Internet

Re: CCIE Questions...
The CCIE is a great certification. These people are simply trying to ensure that it retains its integrity. I look forward to taking a test that 70% of people fail the first time. If and when I pass, it will mean a lot to me. Wojtek - Original Message - From: "John Kaberna" [EMAIL PROTECTED] To: "Lori S Carter" [EMAIL PROTECTED]; [EMAIL PROTECTED]; "Bradley J.

I bet a lot of you got beat up and teased frequently in high school. Let Cisco worry about its NDA. It doesn't need a bunch of dorky Boy Scouts (and Girls Scouts of course) doing its job for them.

I'm assuming there's someone from Cisco who's responsible for monitoring Cisco-related newsgroups and mail lists for NDA breaks, but then again maybe not - what a job from hell that would be.

Question 1: Router A and Router B are configured to route IP to each other over a serial line. Host A is connected to Router A and Host B is connected to Router B. A packet is sent from Host A to host B. A hit on the serial line causes an error in the packet. Retransmission is sent by: Question 2: During the middle of a TCP conversion across a routed backbone, the network receives a voltage spike and several of the packets are damaged. Where are the packets retransmitted from? Question 3: Computer1 [Segment A]---RouterA--RouterB--[SegmentB]--Comp u ter2 A packet is sent to Computer 2 from Computer 1. A collision occurs on Segment B. Which device will retransmit the frame and what will the source MAC address be (when the packet actually reaches Segment B)? Question 4: When computer A sends a frame to computer B across many routers, how will the source and destination layer 3 addresses change? How will the source and destination layer 2 addresses change? **NOTE: New CCNA/CCDA List has been formed.
