Re: It group study worth it or not!!!??? [7:6837]
Hi all, Fairly basic question I think, but as I've not had anything to do with Newsgroups before this one, I don't know the answer: I take it that if you subscribe, you send an e-mail which goes to everyone who's subscribed, but if you don't subscribe, (ie. you just post to the newsgroup) the only people that see your message are the ones that view the newsgroup. Is this the case, or have I got it wrong? One more quick question. Has the formatting of the threads gone all to pot. I've sent a couple of e-mails to Paul with a low priority asking if something is wrong, as I have a couple of other news groups which are fine. The problem seems to be that threads never seem to go deeper than one post, threads get separated, threads marked as 'watched' do not function correctly. Anybody? Cheers, Gaz Michael L.

RE: Cisco moving to a one day lab? [7:6735]
Any CCIE or CCIE candidate worth his salt would want the lab to be tougher. A number of study aids are now available that were not in the past. This has somewhat lessened the difficulty of the process (as witnessed by the backlog of people taking the lab after breezing through the written). Making it tougher is just a method of counterbalancing all of the increased study aids and maintaining the value of the CCIE cert. If you truly want to obtain your CCIE then you should want it to be as difficult as possible, otherwise where is the value in the cert? If you are not up to the challenge, then don't make the attempt. As for who should evaluate the CCIE program - most (not all)employers couldn't begin to answer the questions about what is needed from a CCIE. The biggest employer of CCIE's is Cisco (by far) so they should already have an idea of what is needed. Cisco has been respectful enough of the CCIE population to also ask for their input and most have given it willingly. My main interested is in preserving the value of the CCIE cert. I am currently studying for my 2nd CCIE cert and still hope they make it tougher (before I complete it). I also hope they make the recertification tests tougher as well.

BGP -Maximum Paths [7:6887]
Hey gang, I have a question on maximum-paths in BGP; This is the scenario: 4 T1's running EBGP to our ISP in a multihome peer session; each of the circuits go to a different POP. Each of the peer sessions receive a partial routing table from our provider. What we have found is that load sharing (outbound to our ISP) is virtually non-existant. well, i'm studying for BCSN and came across the maximum path feature, and it seems like the solution. My question is this: we have enabled maximum-path 4 to load share between the four sessions. This, however has had a neglible effect. Does the fact that we still hear routes from the provider from different pops affect this? In other words, since the 4 pops are in a different geographical area, and therefore may send a different bgp table which in turns overrides the maximum path command. I want to try having the provider send a default route instead; the thought being that our router will not have to decide on best paths, and leave that to ISP router, but the powers to be don't want that (for some reason...)

Re: BGP -Maximum Paths [7:6887]
BGP multi-path only works with *identical* prefixes, the only difference between the paths permitted is the router-ID of the originating router. Are you certsin that you are receiving identical routes from all the PoPs? If you have four T-1s I would suggest that before worrying about load-balancing, you seriously look at resilience in your uplink - ie split your T-1s out over at least one other router. As far as load balancing goes, and assuming that the PoPs are all pretty equally connected, it is up to you how to weight the routes. A really basic, semi-arbitrary way might be to match as-paths on each link as transiting each of the top 4 Tier-1s: UUNet - AS701 CW - AS 3561 AboveNet - 6461 BBN - AS1 (not sure my details are entirely up to date, but open to comment) and the set the local-preference to 100 for these paths on each router this might be a starting point - it is a coarse grained way to split the traffic, you can fine-tune from there. it may be worth checking those AS-paths on each router to see whether any one of the four is best connected to those routes. hth Andy - Original Message - From: moe humm To: Sent: Saturday, June 02, 2001 5:01 PM Subject: BGP -Maximum Paths [7:6887] Hey gang, I have a question on maximum-paths in BGP; This is the scenario: 4 T1's running EBGP to our ISP in a multihome peer session; each of the circuits go to a different POP.

My question is this: we have enabled maximum-path 4 to load share between the four sessions. This, however has had a neglible effect. Does the fact that we still hear routes from the provider from different pops affect this? In other words, since the 4 pops are in a different geographical area, and therefore may send a different bgp table which in turns overrides the maximum path command. I want to try having the provider send a default route instead; the thought being that our router will not have to decide on best paths, and leave that to ISP router, but the powers to be don't want that (for some reason...)

OFF TOPIC: Californai Wants You! [7:6892]
January 2000 Love my new job here in Silicon Valley. My salary is 30% higher! I have stock options! The temperature outside is 65F in winter! California is the best place on earth!!! Sure glad I moved out here. February Still looking for an apartment. Freeways everywhere to take you places. Love California! March Found a 1-bedroom apartment for $1900/mo. California is a bit more expensive than I thought. April Gas hit $2.29/gal. Somebody stole the gas from my car. That sucks May A small earthquake! And this is what everyone was so worried about? Almost didn't feel it. June A forest fire and a mud slide near LA. Who cares, that is far away from me! July A big earthquake... Spent 4 hours in my bathtub. Boy, that was scary. Glad we didn't have no stinking earthquakes where I grew up. August Drought! They turn on the water once a day. This sucks big time! Somebody stole the water from my car's radiator. Why did I come to California? September Decided to buy a house. Found a 2-bedroom fixer-upper for $800K. Borrowed against my stock options for down payment. Freeway traffic is worse. Today it took nearly two hours to get to and from work...each way. October My startup fired 90% of the work force, including me. The stock lost 98% of its value. My options are underwater. November Had to sell my house. Couldn't make the payments. Found a studio apartment for $2300/mo. The traffic is unbearable December Problems with electricity. They turn the electricity off several times a day. It's called rolling blackouts. Somebody stole my car battery...what do I do now? January 2001 I'm typing this, stuck in an elevator, in complete darkness. The battery of my laptop is dying. Silicon Valley is no more. Angry hordes of former dot-commers are looting in the dark. It was fun while it lasted. I'm coming back home tomorrow.

Re: Cisco moving to a one day lab? [7:6735]
I agree with you. It's awful easy for someone who's already gotten their CCIE (which when they passed the lab probably could be quoted as saying something like that was the most difficult thing I've ever seen) to now say Sure.. make it as difficult as possible I don't know many CCIEs personally. Only a couple, and both of them said that given the time constraints of the lab (2 days), it is extremely difficult. So I don't think jamming it into 1 day just because Cisco is too cheap to spring for more testing centers to keep up with demand is a resonable solution. Isn't this why Cisco is contemplating making it 1 day? Not to raise the bar of the level of the exam, but simply because they're testing centers can't handle the demand. Mashing into 1 day, IMHO, would be a very poor decision. Agreeing with Brad, do all of the CCIEs that are out there have a problem with leaving the bar where it was when you passed it? It only seems fair. Mike W. Bradley J. Wilson wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]... If I weren't up to the challenge, I wouldn't be on this newsgroup. Are you up to the challenge of leaving the bar at the same height that it was when *you* passed the test? I personally think the test is difficult enough as it is. Am I a wimp because of that? Do we need to dump some dirt on the top of Everest now that it's been conquered by someone else ahead of me? If Cisco wants to make the test tougher, they're well within their rights to do so.

[7:6735] Any CCIE or CCIE candidate worth his salt would want the lab to be tougher. A number of study aids are now available that were not in the past. This has somewhat lessened the difficulty of the process (as witnessed by the backlog of people taking the lab after breezing through the written). Making it tougher is just a method of counterbalancing all of the increased study aids and maintaining the value of the CCIE cert. If you truly want to obtain your CCIE then you should want it to be as difficult as possible, otherwise where is the value in the cert? If you are not up to the challenge, then don't make the attempt. As for who should evaluate the CCIE program - most (not all)employers couldn't begin to answer the questions about what is needed from a CCIE. The biggest employer of CCIE's is Cisco (by far) so they should already have an idea of what is needed. Cisco has been respectful enough of the CCIE population to also ask for their input and most have given it willingly. My main interested is in preserving the value of the CCIE cert. I am currently studying for my 2nd CCIE cert and still hope they make it tougher (before I complete it). I also hope they make the recertification tests tougher as well.

Re: another OT: why you UNIX guys look down on we NT guys? [7:6896]
In case you haven't noticed, most CCNA books point out the fact that the IOS uses a Unix-ish shell, with command line completion, etc. just like Unix.

TCP Sliding Windows question [7:6899]
I am reading Doug Comer's excellent book Internetworking with TCP/IP vol 1. Highly recommended, and I wish I had followed the good advice of several other people on this list, and read the book a year ago. I have a question on sliding windows as Comer describes it: The TCP sliding window mechanism operates at the octet level, not at the segment or packet level Comer goes on to describe the operation of the mechanism, and indicates that acknowledgements occur octet for octet. This strikes me as highly inefficient, and something that would render TCP unusable in networks of any size. Because acknowledgements are based on sequence numbers, there would have to be a TCP header for every octet. Not good at all. I am no doubt missing something fundamental here. Perhaps TCP stack implementations are written in such a way that the octets being sent and acknowledge via the sliding window mechanism are really segments / packets? I.e. hundreds of octets at a time? Can someone enlighten me? Chuck One IOS to forward them all. One IOS to find them. One IOS to summarize them all And in the routing table bind them. -JRR Chambers- Message Posted at: http://www.groupstudy.com/form/read.php?f=7i=6899t=6899 -- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]

Re: Cisco moving to a one day lab? [7:6735]
I'm a little puzzled by all this. Certifications are fine, but they are a beginning, not an end. Now, I freely admit I'm in an odd position. As far as I am concerned, I met the equivalent difficulty of CCIE in the pre-1975 CCSI program, which was radically different. I can't see my career advancement being improved in the slightest by having a CCIE, because I have credentials that are worth more to me. Now that Cisco is so aggressive against study sites, I've made a conscious decision not to get a CCIE so I can't be accused of NDA violations. Yet I think my record is sufficient to demonstrate I believe in helping people getting CCIE and lesser certificates. But I do believe that at some point, certification is enough. Even in medicine, you go through National Boards, then usually the boards for family practice or a primary specialty, maybe a specialty like cardiology or infectious disease that does have a certification, but even fellowship training beyond that doesn't have certification requirements. There may be a need to take a certain amount of continuing education courses. But the real credentials come with doing, and that can be in an assortment of areas. I've designed some big and complex networks, but now work more on protocol performance and product design (and no, I can't get into what I'm working on). But one indication might be my most active IETF activity on BGP router convergence, the new edition of which will be coauthored by Nortel, Cisco, Nexthop, and Juniper. Participating in professional societies is a real thing you can do, and don't tell me it's too difficult. Local groups of IEEE, ACM, etc., meet locally, as do many user groups. Most of the IETF and NANOG work is done on open mailing lists, although it does help to go to meetings. Presenting your more interesting designs and troubleshooting can fall into professional activities, mentoring programs, etc. Trade and professional journals always are looking for contributors. You think having three or four or five pages of publications and presentations doesn't help your resume? Guess again. When it comes to passing exams, there is a point at which I remember the technical term used for the dumbest medical student that passes through school: doctor. Make the CCIE lab more difficult? With more unrealistic rules like don't use static routes when they are appropriate design? Keep trying to show complex phenomena with six routers that really might not show up before sixty?

Re: TCP Sliding Windows question [7:6899]
TCP sequences bytes. A lot of people assume that TCP sequences packets or segments, but that's not true. The sequence number in a TCP header is the sequence number of the first byte in the payload. It's not a segment number. The ACK is the number of the next byte of payload expected. It's not a segment number. The sliding window keeps track of how many bytes have been sent and acknowledged. The 3-way handshake kind of breaks this rule, which is probably why people get confused. They never go past the 3-way handshake. With the 3-way handshake, there are no payload bytes. The recipient's ACK number is nonetheless one more than the other side's SEQ number. Follow the sequence number and ACKs in the following trace, after you get past the 3-way handshake in packets 1-3: 1 MyPCServer TCP HTTPS= 2821020, L=0, A= 0 2 Server MyPCTCP HTTPS=2134278484, L=0, A= 2821021 3 MyPCServer TCP HTTPS= 2821021, L=0, A=2134278485 4 MyPCServer TCP HTTPS= 2821021, L= 384, A=2134278485 5 Server MyPCTCP HTTPS=2134278485, L=0, A= 2821405 6 Server MyPCTCP HTTPS=2134278485, L= 156, A= 2821405 7 MyPCServer TCP HTTPS= 2821405, L=0, A=2134278641 8 MyPCServer TCP HTTPS= 2821405, L= 304, A=2134278641 9 Server MyPCTCP HTTPS=2134278641, L=0, A= 2821709 10 Server MyPCTCP HTTPS=2134278641, L= 156, A= 2821709 11 MyPCServer TCP HTTPS= 2821709, L=0, A=2134278797 Priscilla At 02:10 PM 6/2/01, Chuck Larrieu wrote: I am reading Doug Comer's excellent book Internetworking with TCP/IP vol 1.

Re: BGP -Maximum Paths [7:6887]
It seems that if you are only getting partial routes from each of the connections, you are probably using your gateway of last resort for most of your outbound traffic. When you enabled the maximum-paths, you enabled load balancing for the partial routes you are getting, but again, that is probably not what most of your traffic is going to.

Re: Cisco moving to a one day lab? [7:6735]
This has somewhat lessened the difficulty of the process (as witnessed by the backlog of people taking the lab after breezing through the written). When the junior certs were introduced, it was pondered whether they should be a pre-requisite to the CCIE written or as I have read before - make the CCNP/CCDP the pre-requisite for the lab. On a FAQ at one time, Cisco said that eventually the CCIE would become part of the career certification track which was to say that you would need to go through the junior certs before attempting the CCIE. With the onslaught of new study material, bootcamps, virtual racks et al, I think it is time that the CCIE written be retired and the CCNP/CCDP be the CCIE lab authorization. Or, because the CCIE written still has stuff that is not talked about much any more (if at all) in the current R/S curriculum, then a smaller CCIE written to cover those topics but integrate it into the present career track. CCNA - CCNP/CCDP - CCIE Written - CCIE lab. This way, we could get rid of the idea of passing one exam and then clogging the calendar for the CCIE lab. If you have to get from 4 - 7 exams before the lab, that would perhaps slow things down and maybe (just maybe) increase the success rate at the lab. Hopefully this would stave off any loss of respect for the cert and perhaps even increase it.

This has somewhat lessened the difficulty of the process (as witnessed by the backlog of people taking the lab after breezing through the written). Making it tougher is just a method of counterbalancing all of the increased study aids and maintaining the value of the CCIE cert. If you truly want to obtain your CCIE then you should want it to be as difficult as possible, otherwise where is the value in the cert? If you are not up to the challenge, then don't make the attempt. As for who should evaluate the CCIE program - most (not all)employers couldn't begin to answer the questions about what is needed from a CCIE. The biggest employer of CCIE's is Cisco (by far) so they should already have an idea of what is needed. Cisco has been respectful enough of the CCIE population to also ask for their input and most have given it willingly. My main interested is in preserving the value of the CCIE cert. I am currently studying for my 2nd CCIE cert and still hope they make it tougher (before I complete it). I also hope they make the recertification tests tougher as well.

RE: TCP Sliding Windows question [7:6899]
Thanks, PO. I should add that after I posted, I continued my reading, and a couple of pages later, Comer goes into a detailed explanation about how this works. Let me try to explain in my own words, and let's see if I get it. Starting with me as a user. I want to download a Windows NT service pack - mucho megabytes. Before the file transfer actually begins, the TCP deamons on my PC and the Microsoft server agree on a window size. I'm going to use round numbers to male the math easier. We agree that the window size is 64K bytes - the server will send me 64K bytes before it expects an ack from me. Let's further say for argument's sake that the MTU throughout the network path is 1000 bytes. I'm also going to skip calculations involving headers and stuff because I want to keep this simple. But I do understand that TCP and IP header sizes are accounted for by the sending TCP deamon. OK, the window size is 64K bytes, and the packet size is going to be 1000 bytes. Therefore TCP can send 64 packets ( segments ) before expecting an ack. All right - file transfer begins. My machine receives the first packet. It sends an ack that tells the sender that of that 64K byte window, I have received bytes 1 through 1000. Now, suppose some packets arrive out of sequence. Let's say I receive packet 20 before I receive packet 19 ( of the 64 packets accounted for in the TCP window my ack tells the sender that I have received bytes20,001 through 21,000. If I never ack packet 19, ( or rather, the bytes contained within that stream ) then only packet 19 is retransmitted by the sender. The fact that a number of packets ( number of bytes ) can be sent before requiring acknowledgement makes the whole process a lot more efficient. That's where I got confused. For whatever reason I had come to believe that TCP acknowledged based on packets. I believe I understand this now. TCP operates on packets ( segments is the more correct term ) and acknowledges that it has received so many bytes out of the byte count indicated by the window size. Amazing how it makes sense when you 1) read the material and 2) apply a bit of thought.

I have a question on sliding windows as Comer describes it: The TCP sliding window mechanism operates at the octet level, not at the segment or packet level Comer goes on to describe the operation of the mechanism, and indicates that acknowledgements occur octet for octet. This strikes me as highly inefficient, and something that would render TCP unusable in networks of any size. Because acknowledgements are based on sequence numbers, there would have to be a TCP header for every octet. Not good at all. I am no doubt missing something fundamental here. Perhaps TCP stack implementations are written in such a way that the octets being sent and acknowledge via the sliding window mechanism are really

The jam doesn't have to be all ones, though. On old bus coax networks, it was actually rare to see the jam because by the time the jam happened the clocking was so messed up that the Sniffer had already stopped capturing and just reported a runt, CRC error, collision. On a network with repeaters (hubs), when the repeater detects a collision it sends a 96-bit jam composed of alternating ones and zeros, which would look like 0xAAs or 0x55s. That's easier to see. A lot of Sniffers don't capture bad frames or runts, so you wouldn't see any of these jams in those cases. Someone else may have some additional information. It's always been a question of mine also whether you can really see jams or not. Of course in networks where full-duplex switch ports have replaced hub ports, this is no longer relevant.

Thanks, Priscilla Thank You, Ed --- Priscilla Oppenheimer wrote: When a transmitter detects a collision, the transmitter continues to send the preamble, (if the preamble has not completed), and also sends 32 additional bits, which are called a jam signal. The jam signal extends the duration of the collision event to ensure that all stations hear the collision. The contents of the jam can be any pattern that is not intentionally designed to be the 32-bit CRC value corresponding to the (partial) frame already transmitted. Most implementations send all ones. Completely sending the preamble and transmitting a jam signal guarantees that a signal stays on the media long enough for all transmitting stations involved in the collision to recognize the collision and react accordingly.

I should add that after I posted, I continued my reading, and a couple of pages later, Comer goes into a detailed explanation about how this works. Let me try to explain in my own words, and let's see if I get it. Starting with me as a user. I want to download a Windows NT service pack - mucho megabytes. Before the file transfer actually begins, the TCP deamons on my PC and the Microsoft server agree on a window size. The two communicating stations do not agree on a window size. Each side has its own window size. A low-end PC might start with a small window size. A big UNIX ;-) server would likely start with a large window size. I took out the window size parameter in my example below to simplify matters, but my Windows 98 PC started with a window size of 8760 bytes. The server started with 17520 bytes. The window size is advertised in each packet. It specifies how many bytes the station is ready to receive at this time. It can slide closed as a station gets overwhelmed. Hopefully it slides back open as the station hands off bytes from its buffers to the application. I'm going to use round numbers to male the math easier. We agree that the window size is 64K bytes - the server will send me 64K bytes before it expects an ack from me. Let's further say for argument's sake that the MTU throughout the network path is 1000 bytes. I'm also going to skip calculations involving headers and stuff because I want to keep this simple. But I do understand that TCP and IP header sizes are accounted for by the sending TCP deamon. Each side specifies the size of the segment it can receive in the 3-way handshake. The Max Segment Size (MSS) is a TCP option, one of the few ever used. It does not count the TCP or IP header. In my example, both my PC and the server said the their maximum segment size was 1460 bytes. So, in that sense, they took into account the TCP and IP header sizes and understood the MTU, as you say. OK, the window size is 64K bytes, and the packet size is going to be 1000 bytes. Therefore TCP can send 64 packets ( segments ) before expecting an ack. Segment size is 1000 bytes, OK. All right - file transfer begins. My machine receives the first packet. It sends an ack that tells the sender that of that 64K byte window, I have received bytes 1 through 1000. There's no need to send an ACK yet if the window size is 64 K. Now, suppose some packets arrive out of sequence. Let's say I receive packet 20 before I receive packet 19 ( of the 64 packets accounted for in the TCP window my ack tells the sender that I have received bytes20,001 through 21,000. If I never ack packet 19, ( or rather, the bytes contained within that stream ) then only packet 19 is retransmitted by the sender. Packets aren't numbered, so your wording is bugging me, and I don't think the concept is quite right either. The ACK specifies the byte I expect to receive next. It is a single number, not a range. If bytes are missing, I have to keep the ACK at the first byte of the hole. The sender resends everything from there on. If I advertised a window size of 64 K and an MSS of 1000, then I don't have to ACK each packet. I may have time to sort out packets that are out of order as opposed to missing, if that's what you're getting at. The fact that a number of packets ( number of bytes ) can be sent before requiring acknowledgement makes the whole process a lot more efficient. That's right. That's the main thing to understand. That's where I got confused. For whatever reason I had come to believe that TCP acknowledged based on packets. I believe I understand this now. TCP operates on packets ( segments is the more correct term ) and acknowledges that it has received so many bytes out of the byte count indicated by the window size. Don't confuse reliability with flow control. ACKs are used for reliability. Windows are used for flow control. You may have better luck with Stevens, TCP/IP Illustrated.

RE: Problem with home network [7:6922]
Yea, I have a theory. It has to do with the Linux box, defaulting to 100MB. Let's suppose the Linux box and PC are both running at 100 MB/sec but the hub is only 10 MB/sec. Maybe the timing is such that it will not work past one hop. When I recompiled the kernel, maybe the new kernel release changed how the modules works on the Ethernet card, causing it to not detect 10 MB/sec connections and to default to 100 MB/sec. I will do a diff on the code. Who knows? Paul Daniel Cotts wrote: Since you touched the Linux box it would be the first suspect.

Re: Cisco moving to a one day lab? [7:6735]
Well, again, Sir Edmund, just because the newcomers can be better-informed before their attempts doesn't mean that the challenge needs to be altered or is less of a challenge for the individual. Again, I'm not against making certs tougher to achieve. But it sounds like there's a touch of bitterness that these study guides weren't around way back when...well, that's just the way life is. Making the CCIE tougher and still calling it the CCIE is like asking runners to run a 400m race, but then making them run 500m without telling them. ;-) Besides, the argument about the study materials is subjective. Was CCO around when you took the CCIE? Were other engineers around who were studying for it? Were used routers around for you to purchase, and perhaps set up for others to telnet into? I'm sure there were - if you (and/or others) didn't make use of them, then that's water under the source-route bridge. If you want someone to be angry at, be angry at the people who took the CCIE, passed or not, and then went out and wrote books on how to study for the CCIE. But I personally don't think these people are doing a disservice to the CCIE, nor are they devaluing it - and with a consistent 80% failure rate, they're certainly not making it less challenging. The study guides, etc. make it more of a group effort, and there's nothing wrong with that - not against the rules, not against the NDA, and our society wins because we're able to learn from (and teach to) one another, thereby filling the desperate need we have today for knowledgeable network engineers. Don't punish those of us who have not yet earned our CCIE status for using the resources which are available to us - or for having the foresight to create and share new resources.

I work with both os's, so here is my two cents. Everyone should calm down. There is absolutely nothing wrong with being an nt admin. Or for that matter being an Unix admin either. However, for what it's worth, Unix was first and therefore it is alot easier to move from Unix to other operating systems in a job field. If you can understand the Unix language, dos is a breeze. It's an offshoot. However in my experience, just because someone is an NT admin, doesn't necessarily mean they can operate from dos mode. Nt and dos are two entirely different operating systems. However, what what I have seen in my Unix environment, which by the way does not use a gui environment, is much much more challenging. Which I like. === Your quote: I made $240K last year 'cause I had 10 people working for me and I'll make even more this year.

Re: Cisco moving to a one day lab? [7:6735]
Louie, I understand your point about not a multitude of study materials, etc. I can't imagine studying for any Cisco exam without having good books and Cisco's website at my disposal. However, I don't see how having more study material makes the the actual material less complex or performing the hands-on of the lab less difficult. So I don't agree that having those materials available lowered the bar. To make an analogy to high-jumping, I don't believe having the materials lowered the bar, I think it's more akin to having a better coach to tell you how to jump properly to make it over the same bar. And, in my mind, there's nothing wrong with that, since having a better high-jumping coach doesn't cheapen the sport of high-jumping. Previously you said, A number of study aids are now available that were not in the past. This has somewhat lessened the difficulty of the process (as witnessed by the backlog of people taking the lab after breezing through the written). I don't believe this is a good conclusion. You statement makes the assumption that the number of people entering the Cisco field, or at least attempting the CCIE, has been constant. If anything, this is opposite of the truth. I would account for the backlog for the CCIE lab with 2 things: 1) Acknowledging that more and more people are coming into this field and attempting the CCIE. 2) Cisco has done nothing to increase their lab availability to accomodate the new demand. If anything, they're directly responsible for the backlog because now there are only TWO places in all of North America to take the lab. Didn't there used to be 3 places (CA, NC, and Canada)? I'm glad to hear you're going for your second CCIE cert. I sincerely wish you the best of luck! I admire the fact that you look for, and aren't afraid of a true challenge. Mike W.

Only a couple, and both of them said that given the time constraints of the lab (2 days), it is extremely difficult. So I don't think jamming it into 1 day just because Cisco is too cheap to spring for more testing centers to keep up with demand is a resonable solution. Isn't this why Cisco is contemplating making it 1 day? Not to raise the bar of the level of the exam, but simply because they're testing centers can't handle the demand.

RE: Cisco moving to a one day lab? [7:6735]
Yes you are wrong (about my perspective). I have helped several engineers study for and pass the CCIE written as well as the lab. My concern is in preserving the value of the cert. As for dog-eat-dog I'll help anyone who is sincere and wants to learn - providing they are willing to put in the effort. However, I will not give them the answers so that they can make the value of my cert less. Prior to so much study material being available, you had to study and know how to handle a wide array of issues, the specifics as to what is on the lab were simply unknown and therefore you had to be prepared for anything - and know it well. Now that the study materials have become available, it allows a candidate to be more focused on lab specific issues instead of on routing and swicthing in general. As a result a candidate can now pass the lab without having a decent broad knowledge of routing and switching, they just need to know how to prepare for the lab. That in my opinion has devalued the certification. If we have 100,000 CCIEs all of which know there stuff and are a credit to the certification then I have no problem with it. It we have 8000 CCIEs and 1000 of them can't live up to the expectations of the certification, then it hurts the value not only of the other 7000, but also of any future recipients of the certification. I am not bitter or angry (thanks for jumping to conclusions) that the study guides weren't around, some were when I received my cert and I certainly used them. I don't want them to go away. I own many of the books written by other CCIEs and use them as a reference quite often. I am thankful they are available. The materials that exist have the potential to help all of us.

[7:6735] Well, again, Sir Edmund, just because the newcomers can be better-informed before their attempts doesn't mean that the challenge needs to be altered or is less of a challenge for the individual. Again, I'm not against making certs tougher to achieve. But it sounds like there's a touch of bitterness that these study guides weren't around way back when...well, that's just the way life is. Making the CCIE tougher and still calling it the CCIE is like asking runners to run a 400m race, but then making them run 500m without telling them. ;-) Besides, the argument about the study materials is subjective. Was CCO around when you took the CCIE? Were other engineers around who were studying for it? Were used routers around for you to purchase, and perhaps set up for others to telnet into? I'm sure there were - if you (and/or others) didn't make use of them, then that's water under the source-route bridge. If you want someone to be angry at, be angry at the people who took the CCIE, passed or not, and then went out and wrote books on how to study for the CCIE. But I personally don't think these people are doing a disservice to the CCIE, nor are they devaluing it - and with a consistent 80% failure rate, they're certainly not making it less challenging. The study guides, etc. make it more of a group effort, and there's nothing wrong with that - not against the rules, not against the NDA, and our society wins because we're able to learn from (and teach to) one another, thereby filling the desperate need we have today for knowledgeable network engineers. Don't punish those of us who have not yet earned our CCIE status for using the resources which are available to us - or for having the foresight to create and share new resources.

Hi Jonatas, This may have already been answered, but I would like to share my experience with this upgrade of PIX 520 .First of all you have to determine your memory size ( flash, RAM) , you might not see thesize of flash when you do # sh ver but you will see 128MB of RAM and as far I know all PIX box with this RAM has 16MB of flash .Also write down your Serial Number it will help you getting the activation key for VPN-DES or VPN-3DES when you send your request to [EMAIL PROTECTED] and provide show version output to them.If you do # wr t at the end of your config . in ver 4.2(4) you might see your key sometime (it depends). Go to www.cisco.com and download the procedure for upgrading PIX 520 and read the procedure carefully and proced to download the ver. you want (I recommend a lowerver. 5. 12 f.i. first and then another one higher f.i. 5.25), so you will have to download the followings file : bh512.bin, bh525.bin, pix512.bin, pix525. bin , rawrite, readme..The procedure has a small typos when you prepare your floppy disk , after formating youhave to C:\rawrite and put the file name : bh512.bin instead pix512.bin and follow the procedure. At the end it will ask you for if you want to change the activation key so if you got it from Cisco TAC you can put it know ...and you are done.Caution: If you have another PIX 520 which is your failover PIX when you plug your failover cable you might run in some problems all you have to do is too wait long enough till you PIX's syncronize , to see you can type # show failover and look to see which box is Active and which is in standby.

THE PROGRAMMING LANGUAGE B ABSTRACT B is a computer language designed by D. M. Ritchie and K. L. Thompson, for primarily non-numeric applications such as system programming. These typically involve complex logical decision-making, and processing of integers, characters, and bit strings. On the H6070 TSS system, B programs are usually much easier to write and understand than assembly language programs, and object code efficiency is almost as good. Implementation of simple TSS subsystems is an especially appropriate use for B. This technical report contains a description of the MH-TSS (Honeywell 6070) version of B (by S. C. Johnson), and a tutorial introduction to most of the features of the language (by B. W. Kernighan). Ken Thompson The principal inventor of the Unix operating system and author of the B language, the predecessor of C. In the early days Ken used to hand-cut Unix distribution tapes, often with a note that read Love, ken. Old-timers still use his first name (sometimes uncapitalised, because it's a login name and mail address) in third-person reference; it is widely understood (on Usenet in particular) that without a last name Ken refers only to Ken Thompson. Similarly, Dennis without last name means Dennis Ritchie (and he is often known as dmr). Ken was first hired to work on the Multics project, which was a huge production with many people working on it. Multics was supposed to support hundreds of on-line logins but could barely handle three. In 1969, when Bell Labs withdrew from the project, Ken got fed up with Multics and went off to write his own operating system. People said well, if zillions of people wrote Multics, then an OS written by one guy must be Unix!. There was some joking about eunichs as well. Ken's wife Bonnie and son Corey (then 18 months old) went to visit family in San Diego.

Williams wrote: Well, having more than one router connected to the same WAN connection still leaves a single point of failure. Where I work, we have hundreds of remotes sites, each of which has 2 routers connected together to the remote LAN using HSRP. One router has a frame relay connection, and the other has an ISDN dial-back up interface to the same WAN destination (Central Site). This way if the primary circuit goes down, the HSRP priority gets reduced (even on a subinterface level) until the connection is completely down, thus router 2 then invokes the ISDN dials. ISDN is cheap, so this sounds like a good method to me for providing redundance without having to mess with trying to connect 2 routers to a single WAN connection.. My 2 cents Mike W. Jon wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]... I've been reading about designing physical redundancy into networks, by having hot standby devices and using HSRP between them. As an example, if a site has a single router and a single core switch, these are points of risk. By adding a second core switch and a second router, any hardware failure should be overcome by the standby device taking over. If all the servers and wiring closet switches are multi-homed to both core switches, users shouldn't notice that a fault has occured. (I assume that the loss of a wiring closet switch is acceptable -- perhaps local spares are sufficient). However, if I only have one WAN circuit coming into the facility, it can only be connected to one router at a time, right? So, if the active router fails, how does the WAN connectivity fail over, short of an operator moving the cable to the second router? I'm not trying to address WAN circuit redundancy or multi-homing, that's a different worm-can to open. Is there some way to have both routers connected to the same WAN circuit? Something along the lines of a WYE-cable that connects both routers to the demarc connection? Or is this something that the circuit provider would address with their equipement (for a fee, I'm sure)? If this has been hashed over in the past, I couldn't find it in the archives.

The problem I'm having is that once the computers have rebooted, and I did a debug ip dhcp server events, packets, linkage, I keep seeing the router still setting the GIADDR of the request as 192.168.5.1 ... since it's forwarding this information, the DHCP server on the central site wasn't responding because of the non-existence of the 192.168.5.0 scope Reading Cisco's documentation, I thought the router uses the primary ip address of the interface as its GIADDR?

RE: Cisco moving to a one day lab? [7:6735]
I agree there is no way to talk apples to apples - too many things have changed - but don't forget you no longer have to deal with LAT, X.25, CLNS, DEC, Banyan Vines, Appollo, Appletalk or ATM Lane. (Voice was already on the lab prior to these items being removed.) My concern is with the material that is not focused on teaching you networking (I have no problem with that), but on the material the simply teaches you how to pass the test (kind of like all of the Microsoft braindump material available - desinged only to help you pass the test). I see too much material as of late that is way too focused on passing the lab, not on learning networking.

Re: Subject: Re: TCP Sliding Windows question [7:6899]
Comments within and below. sort of continuing, although on an IPX track was reading Radia Perlman's book the other day, and she mentions that SPX has a window size of 1. Now, I seem to remember from my DOS/Win3.11 days that there was some kind of SPX burst facility available (with addition TSR drivers). Are you referring to packet burst? In essence, this is what you described(watch wrap): http://support.novell.com/cgi- bin/search/searchtid.cgi?/2947728.htm It was my understanding that many folks wanted to disable this capability and the article makes mention of this in a note on the bottom: Note: Customers have reported that the MS Client for NetWare may cause high utilization on NetWare servers.. Disabling the Packet Burst functionality of the MS Client resolves the high utilization problem. According to one customer, the following registry edit disables Packet Burst on the MS Client: Still, the intent was good. Many folks also associate sliding windows with SPX. Technically, that is not correct. True windowing did not really happen until SPX II, which also facilitated orderly closure of the connection (if requested). Wasn't really au-fait with networking back int those days, but would I be right in assuming that this adds some kind of sliding window functionality to SPX? SPX II to be more precise. In a way, one can regard packet burst as a windowing mechanism, but it was not as refined as SPX II (IMHO). The real issue is why Novell missed the boat on IP. Too little, too late. I am a big fan of Novell Netware. It is a rock solid NOS. Unfortunately market share typically dictates what will be used. The Beta vs. VHS wars are a prime example.

Re: Cisco moving to a one day lab? [7:6735]
As far as this thread goes Ill put in my two cents worth. Im just starting to study specifically for the written right now having just gotten my CCNP so I am in with those studying for the lab now (or real soon). Personally I think Cisco could go right ahead and make the lab as hard as they want. In all honesty I never see the lab being as hard as the orals a 'pure science' graduate student must take. It is only, and will probably ever only be a technical exam and will never even come close to the difficulty of a theoretical examination where new ideas must digested and expounded upon. Everyone has always known what to study, routing and switching on cisco hardware/software, these are not massively huge topics as a fairly comprehensive library would only fill a couple bookshelves. In fact I wouldnt mind if the test was a single question 'Redesign the overall topology of the Internet with regards to emerging traffic patterns expounding upon different paradigms of routing. Give specific configuration examples at all levels of the network using any given piece of Cisco equipment.' The current lab is not that hard and will never be that hard, but if it was I would not be disappointed, I would personally like such a challenge. CCIE is not the be all and end all of knowledge; it is just a verification of technical skills on a small selection of platforms. If it was made more difficult I would not begrudge anyone else who achieved the certification before it was made harder, I am comfortable with my skills and abilities and really feel no need to use a paper certification as a crutch for the future. Studying for the written and lab though does help me to focus and explore routing so I continue to do it. In conclusion, it should be as hard or as easy as Cisco wants it to be, I am confident that I will still pass no matter what when I take the lab a year from now.

Re: Subject: Re: TCP Sliding Windows question [7:6899]
Priscilla's explanation is right on the money I have added a few comments to expand on some areas that were not mentioned. See below. TCP sequences bytes. A lot of people assume that TCP sequences packets or segments, but that's not true. The sequence number in a TCP header is the sequence number of the first byte in the payload. It's not a segment number. The ACK is the number of the next byte of payload expected. It's not a segment number. The sliding window keeps track of how many bytes have been sent and acknowledged. Very correct. The only way to see this is to count the bytes as the go across the wire. To help a little bit, I have included an ASCII capture summary for a TTCP transfer (watch wrap): http://www.west- point.org/users/usma1983/40768/chesinc/docs/ttcp2.txt This is not a theoretical capture, rather a real 10 minute transfer between two windows hosts using a direct connection with a crossover cable. If you look at the first sequence number, you will see it is SEQ=20602846 . Look at the window size and the packet length size (8760 and 1460 respectively). We should expect to see five more packets cross the wire before an ACK is sent. You will note that the next sequence number (SEQ=20604306) reflects an additional 1460 bytes. Finally, look at the ACK. Note that the ACK is indicating, Hey, I want to see the **Next** 1460 bytes, hence the number ACK=20611606. This is considered a positive or expectational acknowledgement. The almost full headers are here(watch wrap): http://www.west- point.org/users/usma1983/40768/chesinc/docs/ttcp.txt The 3-way handshake kind of breaks this rule, which is probably why people get confused. They never go past the 3-way handshake. With the 3-way handshake, there are no payload bytes. The recipient's ACK number is nonetheless one more than the other side's SEQ number. What is equally important is that the ISN (Initial sequence number) should be a truly random value, so as not to allow hackers to spoof a connection. There are some pretty well documented cases where this was not done, most recently with the CBOS on the 600 series routers. Also, one point of note is the issue of selective acknowledgements and negative acknowledgements. Originally, most Internet hosts did not have a TCP/IP stack that incorporated SACKs. With the advent of Solaris 8 and Win 98, SACKs were employed in major operating systems. The effect of the selective acknowledgment (as opposed to the negative acknowledgement is as follows. In the instance where you had the transfer I mentioned above, consider the situation where I received segments 1 and 2, missed segment 3, then received segments 4, 5, and 6. Would it not be a little bit more efficient to tell the server that I at least got segments 1 and 2? That is the point behind SACKs. In the case of negative acknowlegements, the intent would be to say to the server, okay, big guy, it looks like I got everything except segment number 2. Whaddya say we resend segment number 2 just to make things complete? Negative acknowledgments are not supported, and likely will not be supported unless the TCP specification is rewritten. Frankly, a good sliding window and SACKs seems to be sufficient for optimization. I **Strongly** agree with Priscilla's endorsement of TCP/IP Illustrated, by W. Richard Stevens. Unfortunately, it is copyrighted September, 1994. It will never be updated by the original author, since he passed away recently. My understanding is that his wife is trying to find somebody suitable to make a next edition (which is long overdue). I hope a suitable person will be found. The Stevens book is a *must* read if you want to understand TCP/IP. v/r, Paul Werner Get your own 800 number Voicemail, fax, email, and a lot more http://www.ureach.com/reg/tag Message Posted at: http://www.groupstudy.com/form/read.php?f=7i=6960t=6899 -- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
Re: Cisco moving to a one day lab? [7:6735]
In my opinion, CCIE's are definitely needed for the internet. What I mean by that is cisco like all others needs people out there to setup and manage networks. Making the exam harder and harder may make a good CCIE candidates, however the markets usually will not wait to get the all-rounder CCxx from Cisco. Because Ms.Juniper and Mrs.Foundry are all pushing for people to be good at making and managing networks. The more reccomenders or users the better sales. When you have more CCIE's and CCNP's and of course CCNA's the more reccommenders for Cisco products. Same is the case with all products. And as long as Cisco can back the recomender with the quality products, there is a good future for CCIE's etc. Few years ago it was Novxx and Microxx certification was the way to go, how ever Novxx could not back the reccommender with quality and so may be doing the last dance now. Microxx just understood the idea but patches for greed is yet to be invented. Judge Jacksxx is still working on it. CCIE is only another level of knowledge. It probably will be seen different if the standard is to have Phd's in networking. So work hard in knowing more. Explore the unknown, expand the known. That is the only way you will be the best in what you do. CCIE is the best now, however what % of every CCIE does the world need. Should they all specialize? By the way, all the above statements are only opinions and should not be used directly or indirectly for any decision making. No Data wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]... As far as this thread goes Ill put in my two cents worth. Im just starting to study specifically for the written right now having just gotten my CCNP so I am in with those studying for the lab now (or real soon). Personally I think Cisco could go right ahead and make the lab as hard as they want. In all honesty I never see the lab being as hard as the orals a 'pure science' graduate student must take. It is only, and will probably ever only be a technical exam and will never even come close to the difficulty of a theoretical examination where new ideas must digested and expounded upon. Everyone has always known what to study, routing and switching on cisco hardware/software, these are not massively huge topics as a fairly comprehensive library would only fill a couple bookshelves. In fact I wouldnt mind if the test was a single question 'Redesign the overall topology of the Internet with regards to emerging traffic patterns expounding upon different paradigms of routing. Give specific configuration examples at all levels of the network using any given piece of Cisco equipment.' The current lab is not that hard and will never be that hard, but if it was I would not be disappointed, I would personally like such a challenge. CCIE is not the be all and end all of knowledge; it is just a verification of technical skills on a small selection of platforms. If it was made more difficult I would not begrudge anyone else who achieved the certification before it was made harder, I am comfortable with my skills and abilities and really feel no need to use a paper certification as a crutch for the future. Studying for the written and lab though does help me to focus and explore routing so I continue to do it. In conclusion, it should be as hard or as easy as Cisco wants it to be, I am confident that I will still pass no matter what when I take the lab a year from now. Ben, CCNP --- Circusnuts wrote: Louie- I don't think we're talk'n Apple to Apples here... During the early CCIE exams, I was told candidates were able to use their own notes during the test (if Pamela Forsythe is out there, she could confirm this rumor) can you imagine how much easier the lab would have been with versions 9.0, 10.0 or even 11.0(22) IOS. I agree there's more information available, but after having sat through a 2 week CCIE lab prep class... I think the information just gets you in the ballpark. Things like bad time management poor interpretations, are big obstacles no book can fix. I believe the exam is as hard (if not harder) than it's ever been.

[7:6735] When the CCIE cert first came about there were not 100+ books avilable to help you pass it. There were not a multitude of online labs, lab study guides, study groups, ... Since all of those items are now available, I feel the bar has been lowered. I'm for putting it back where it was. Additionally I'm studying for my second CCIE cert, I sincerely hope that it is much tougher than my first. I want to maintain the value of the cert. Louie -Original Message- From: [EMAIL PROTECTED]
