Re: Frame relay map 0.0.0.0 question, please help! CCIE lab is [7:31575]
Did you change the Hub router's ospf priority so It will become DR? And change The spoke routers' ospf priority to 0 so it will never attempt to become DR or bdr? And also, if you have NOT issued the command clear frame inarp (12.1 and above) or clear frame-inarp (12.0 and below), the map statements will remain until you reload the routers. That will need to be done on router B and router C. Routers B and C do not form adjacencies with each other in this topology *unless* you make use of the full mesh, which you've been instructed *not* to do. They both form adjacencies with Router A. That's why you add a map statement to each Router B and Router C to point them to each other via their respective DLCI's to Router A, unless you're explicitly told not to do that. (Which is whole different can of worms) My strategy is shut off inverse arp, clear frame inarp, get the map statements into the config, write the config, and reload. You may wish to reschedule your Feb lab date if you're at this point with OSPF and frame relay a month or so away from your lab. It only gets more complex than this, and this concept, while not elementary, is 'core' to your success in the lab exam. -Original Message- From: Wilson, Christian [mailto:[EMAIL PROTECTED]] Sent: Thursday, January 10, 2002 12:23 PM To: [EMAIL PROTECTED] Subject: Frame relay map 0.0.0.0 question, please help!

You also need to consider to use the newer Cisco method which is IP OSPF NETWORK TYPE. Neighbor command is an old mehtod of doing it and not recommended anymore. Good point. You better be able to do it in every way that's available. What if your directions were don't use neighbor commands, as a few of the lab preparation guides suggest? Also, be mindful that older versions of IOS (pre 12.0, I believe) did not have ospf network-type point-to-point Just in case you run into that in the real world.

Re: What equip is really necessary for lab studies [7:31295]
Everyone asks this question, but the answer, Young Skywalker, comes from within. ;-) The answer is It depends. Ask yourself these questions and you'll probably come up with the answer that's right for you: 1. Where are my weak points technically? (My answers were Token Ring and ISDN, so that's where I spent my money) 2. How much am I willing to risk going into the lab? (If you don't have a lot of experience with ISDN, for example, is it worth not having a lot of ISDN time knowing that it could cost you points on the exam?) 3. What's my level of experience with the technologies that I can just review versus the ones I need to practice over and over again? If you're weak on everything, then buy everything with the context that you're just renting it until you pass your exam. It may give you the needed motivation to get the studying job done quicker. And then, once you've passed, resell the equipment at that present market value (in other words, don't expect to recoup your investment, because price erosion on equipment is a reality - just ask our friends on the list who paid $1000 for a 2501 a few short years ago). -e- - Original Message - From: Michael Witte To: Sent: Tuesday, January 08, 2002 11:14 AM Subject: What equip is really necessary for lab studies?

Of course it would be nice to buy every piece of equipment on the CCIE lab list but sometimes that is not practical for people that have kids to feed. Anyway I would like some input on what I equipment I really need to concentrate on. Right now I have a 2523 for my frame-relay switch, a 2524,2504,2 2610's and 2 1900's. All have latest IOS and is sufficient for doing most OSPF, BGP and anything else. I was planning on getting a 2513 for translation bridging, and a 5500 and 2620 so I can do a router on a stick and VLAN stuff. I am 99% sure I need fast ethernet to do ISL and inter-VLAN routing hence the 5500 and 2620. I realized yesterday that the 4500 can support fast ethernet and token ring so instead of the 2513 and 2620 I can use this. I am also planning on getting a Teletone simulator for ISDN. As far a VOIP,ATM,and the 3900 I was going to use some rack time for practice. Here is what I need input on: 1)5500 and 4500 for inter-Vlan routing and VTP- Can I get away with rack time? 2)ISDN simulator- Again can I get away with rack time? 3)VOIP,ATM,3900 -rack time?

Re: Can ne1 Help me??? [7:30892]
This means you have a router connected to a switch with one fast-ethernet or gigabit-ethernet link. This link is configured as a trunk and the router routes the vlans of your switched ethernet via that one trunk-link. It's not always necessarily a trunked interface. I've seen many implementations that used a standard Ethernet interface as the arm and just routed inbound traffic to the same interface outbound. It's horrible from a design and performance perspective, but it accomplished what was required in the environment, and they were stuck with it until a infrastructure redesign project re-addressed the problem. The terms router-on-a-stick and one armed router come from the principle that the same packet travels the same interface both inbound and outbound, so that the router basically only has one live interface (as opposed to two or more, which is what we typically implement) Allso called a lolly-pop router.

Re: OSPF into iBGP with Sync [7:30126]
the first thing that comes to mind is that OSPF is the only other routing protocol where RID is an inherant part of the structure and the process. as to why this becomes an issue, since RIDs can change based upon reconfigurations and reloads and process clearing, I can see the code getting confused. add a loopback. clear the ospf process, the RID changes, but does not change for BGP because the process is stable. or visa versa. this is starting to tell me that maybe there is a RID routine in the IOS code that both BGP and OSPF reference when starting up. write it off as cronkite because that's the way it is? not a bug, but a feature? the 'feature' is a pretty tricky deal. what the sync 'feature' required is the RID for the OSPF route match the RID of the BGP route. John came up with the solution, and it worked. The redistribution point also plays a key role - when redistributing OSPF into BGP, it worked best when done at a BGP router that was sync'ed. The additional complication was a route reflector preventing the real full iBGP mesh. It is a show-stopper if you don't get that match and try to get unsynced iBGP routes advertised to an eBGP neighbor. My conclusion: The additional sync requirement of matching OSPF RIDs (instead of just the routing table) is a real pain in the butt. Chuck John Neiberger wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]... We discovered something on the CCIE list recently and I'm wondering if anyone might be able to explain the reasoning behing this behavior.

OSPF didn't play much of a role in transit networks during the time when synchronization was a relevant option as far as I know so I doubt there was very extensive testing done on this particular feature. I would expect this was just an additional check to ensure route authenticity. Given this feature is many years antiquated, I'm surprised so many folks try and make it work. unfortunately, if it were as simple as just that, I could just deal with it. However, when it affects my ability to propagate iBGP routes to an eBGP neighbor, and the restriction is sync on all but the route reflector router, a solution has to be figured out. If it were on the lab exam, I'd probably disable sync if I got desparate (and kiss some points goodbye) if I didn't know the answer. Therein lies a good point for the lab exam: Know what your contigency (backup) plan is if you can't figure out the solution that you're being pointed to so that you can at least get the darned thing running and you can move on to the next step. pete At 06:23 PM 12/26/2001 -0500, John Neiberger wrote: We discovered something on the CCIE list recently and I'm wondering if anyone might be able to explain the reasoning behing this behavior.

I was amused by this thread and read most of the other responses. I'd say most of them were right on track (NOT). But they were amusing. I'll add to the amusement. If you wear a proper dress and you're a guy, you'd surely get the proctors' attention. Especially if you shave your legs. You might even scare them into passing you. My experience - dress comfortably. Be prepared for cold. And warm. Be hygienic. (for the real nerds out there, that means take a shower and brush your teeth. and try not to sweat/perspire too profusely) I never did see a sign in there that said no shoes, no shirt, no service (oops, is that an NDA violation?) Also, wearing a NerdGear t-shirt with subnets/masks and the Class A B C definitions would probably NOT be recommended. Although I've debated wearing mine on Jan 15th, 2002 just for kicks.

Re: ccbootcamp labs [7:29512]
The trouble is that Cisco has made this certification seem so unachievable and so frightening and of course so much wantable that it creates a market for knowing the unknown and taming the untamed. So you are ok, in looking at the tremendous opportunity amidst all this, and make a business out of it. The people who have passed (about 7500 of them) don't think it's unachievable anymore. The trouble is not Cisco - it's the experience of people who go into the lab unprepared and discovering that it's not just configuring basics on a router. Also, echoing Dave Madsen, in the 'old days', there were no study materials (unlike other certification programs), which made the lab that much more mysterious, and the NDA is so strong that no one would dare step out to share information. I am also aware of the fact that nothing in this world is free, and anything that is free is NOT APPRECIATED. But there is a limit to how much you can charge, especially with the non-proprietory nature of the knowledge. 650$ translates to roughly 1200$ over here in Australia, and would translate to about 30K in some places in Asia. And that includes just scenarios. I appreciate the FatKid (free) labs. In fact, I've offered on one occassion to help Derek modernize and expand the lab scenarios. His lack of response indicates his interest in that endeavor. So what are you doing, creating another MICROSOFT ? Interesting question. I'm interested in Marc's answer. _ Do You Yahoo!?

All labs should not exceed more than 6 routers. I think we all know why this should be the case. 2. The frame cloud in every lab should not exceed four connections. I have spoken to several people who complain about the current competition use 5 connections in the frame cloud. Most of us only have the four port 2500 at home that acts as a frame switch. 3. Keep it up to date. How difficult is it to do a practice lab while trying not to be distracted by some technology that is not on the test any more. 5. Keep it original. Create your own work, don't take a lab out of Halabi's book, add an extra router, then slap a 650 dollar price tag on it. 4. Keep it FREE. I don't know about the rest if you, but after dropping 13,000 dollars in a lab at home, and 4,000 dollars in training, spending an extra 650 just hurts. I think my game plan is, at least for the first few labs, to create a map in visio with some core requirements. Then the group can suggest such things as Local Area Mobility, NAT, etc that can be incorporated in to the lab. Where can we post the labs? Can every one read visio? Do we have to send it out in a different format? And yes Marc, the email is bogus. I did not want to be spammed by you or your affiliates. _ Do You Yahoo!?

Re: Token Ring Setup Help [7:29351]
- Original Message - From: Andrew Michael To: Sent: Sunday, December 16, 2001 1:51 PM Subject: Token Ring Setup Help [7:29351] Hi everyone. I'm unsure of which cabling I need to set up a token ring lab. Currently, I have four ISA Token Ring cards. These cards have an RJ-45 and D-9 connections available. Is there an advantage of using one over the other? What do the pinouts look like for a token ring network? The RJ-45 connector is for UTP (unshielded twisted pair, also known as IBM Type 3) token ring wiring systems. RJ-45 Token Ring MAUs (Multistation access units) are available for these, and you can use standard Cat5 (EIA/TIA 568A or 568B) patch cables. The DB-9 connector is for STP (shielded twisted pair) or Type 1 (an IBM nomenclature) token ring wiring systems. IBM 8228 MAUs are available for these connections. The associated patch cable is an STP cable, DB-9 male to an IBM Data Connector (it is a connector that looks like it could plug into itself, also known as Boy George connectors). There are also cables that are RJ-45 to IBM Data connector, and DB-9 to RJ-45 (known as media converters) The advantage of using the UTP wiring system is the ability to use any Cat5 wiring system to connect the token ring stations. The STP wiring system is typically bulky and considered obsolete today. However, it was also considered to be more dependable than the Category 3 cabling that was available at the time the Type 1 system was introduced. Here is a link to a page with the pinouts for either: for RJ-45 http://www.cisco.com/univercd/cc/td/doc/product/access/acs_fix/accespro/accp roug/apugcble.htm#31516 (watch the URL Wrap) for DB-9 http://www.cisco.com/univercd/cc/td/doc/product/access/acs_fix/cis2500/2505/ 2500him/77412.htm#xtocid1972510 (watch the url wrap) Any help greatly appreciated!

Re: What is our Quest? [7:29085]
Mentor did something very similar with their vLab offerings. This sounds like a recreation/alternative to those labs, which in my humble opinion were very good from 1) an accessability perspective (globally available and accessible) 2) a learning perspective (taught the basic principle through configuration 3) a documentation perspective (the proposed solutions were usually correct because they'd been checked) 4) a challenge perspective (if one tried to do the configurations without the solution, there were definitely issues that needed to be addressed) Although they were more training centric versus certification-centric, labs were categorized by skill level (beginner=CCNA, intermediate=CCNP/early CCIE, advanced/expert) The only thing restrictive (and really not that restrictive all things considered) was the relatively high cost per session (min $40 for a 3 router pod for 60-90 minutes of virtual lab time). $40, and one thin mint, btw.

Berkowitz To: Sent: Thursday, December 13, 2001 7:58 AM Subject: What is our Quest? [7:29085] [If the subject line is ambiguous, please consult your Monty Python.] DISCLAIMER: I am involved in several commercial efforts for paper scenarios and virtual racks. I think the issues raised here, however, are of value to the community. --- Certification (and network learning that is not strictly certification related) involve scenarios for practice. It's my belief, however, that not all scenarios are the same. I'm not referring here to their quality, but to my belief that there are several types of scenarios that help in different aspects of the learning process. I'd really like feedback from the community if this thinking makes sense. 1. Technology familiarization scenarios 2. Complex problem recognition troubleshooting tests 3. Specific exam preparation (e.g., CCIE lab time management) 4. Non-certification (e.g., practice for real-world multihoming without CCIE restrictions, server interactions, etc.) If you were obtaining scenarios over a period of time, what would be your priorities? Type 1 -- 1a) This can reasonably begin with a preconfigured 1-3 router CCNA level system, that just allows CLI practice and the use of show/debug commands. 1b) The next level can be anywhere from CCNA to CCIE level, but focusing on a single protocol/technology. Other technologies are used only to support the primary objective. For example, my upcoming CertZone X.25 scenario starts by establishing OSPF routing (configuration given) over a serial line with HDLC encapsulation, then walking the student through the issues in converting to LAP-B and X.25 encapsulation. A basic such scenario gives the objectives and possibly some criteria for successful configuration, but doesn't give step-by-step guidance, illustrate common errors, and include troubleshooting. 1c) A more structured presentation, typically introducing common errors and showing how they are discovered and corrected on the way to a correct solution. 1d) Compare-and-contrast multipart scenarios, such as an OSPF scenario that explores several different aspects of partitioning and virtual links (e.g., connecting OSPF Area 0.0.0.0 across a non-OSPF domain, fixing an OSPF partition with a virtual link through a nonzero area, then examining the other application of virtual links: connecting noncontiguous areas to the backbone) Type 2 -- This is much more like an actual Cisco test experience, but giving the flavor of mentoring rather than time pressure. For example, you might be given an address plan, and told to implement OSPF in part of the network and RIP in another. You'd first get the individual protocols working, perhaps being guided through some common errors and how to spot them. Next, you'd set up redistribution, again with advice on typical problems. Once you have the redistributed routing working, you'd systematically add other features (e.g., DLSW+, performance management), again with guidance at each step. Type 3 -- Tests here are closer to the published descriptions and concerns of the CCIE lab, and include features such as a visible clock, and the option to choose to get a working configuration for some sub-part, losing the points but being able to go to the next part. In Pythonesque terms, Type 3 scenarios teach you to deal with the troll, but with the issue being the clock rather than the velocity of the sparrow. Type 4 -- My main focus here has been exterior routing for both multihomed enterprises and ISPs, but reflecting best current practice rather than some of the artificialities of the CCIE lab (e.g., encouraging rather than forbidding appropriate use of static and

Great thanks! Wow, that is a lot of questions, and it clearly indicates that you were not ready for the CCIE Written exam. Where did you LOOK for the correct answer? May I politely suggest that you study the information on Cisco more carefully, then provide your own answers to these questions? Those of us who have passed had to learn the answers by reading and then remembering the information. Almost all of the answers that you are requestion can be found at www.cisco.com so please do your studying. Other members have informed you by asking these questions, you are breaking the Cisco Non-Disclosure Agreement that you signed before you took the exam (non-disclosure means, don't tell anyone what the questions or answers are on the exam). You should be concerned that if you are caught violating this non-disclosure agreement, you will be barred from taking the Written Exam. Are the answers to these questions really worth the suspension? Also, CCIE's are usually very independent and know how to do research on a subject before asking questions for help. You should start your training in that manner - do the research FIRST, and then when you can't find the answer, ask us here on the list. PS Many of us know the answers to these questions, and the answers are easily found in the Cisco documentation and in the books that are suggested reading material for the CCIE Written exam. 1..

More than one data frame can circulate the ring at any given time, but only one token is allowed. C. More than one data frame and more than one token can circulate the ring at any given time. D. A station releases a free token after stripping the frame from the ring E. A station can transmit early without waiting for a token to be released from its neighbor. 2.What is the best description of poison reverse? A. It is a procedure used by OSPF to remove a network from the OSPF area. B. Once a connection disappears, the router advertising the bad network will send an update from this network indicating an infinite cost. C. The specific network is not sent out again on the interface it was received on. The network is sent back out on the interface it was received on, but with a metric of one more than the metric in the receive update. 3.In FDD, the characteristics of !04B/5B Encoding!1 include: (multiple answer) A. Sending 4 bits of informations using a 5 bit symbol. B. Increasing the clock rate of the transmitter and receiver to 125Mhz, which establishes an effective data rate of 100Mbps. C. Increasing the distance between two FDDI stations to more than 2km, when using multi-mode fiber. D. Providing a workaround for the optical Bypass Relay. 4.Examine the following: Based on the information above, which OSPF configurations listed are valid?

Re: Question of OSPF Over DDR [7:28666]
I have a question about OSPF over DDR. The lab scenario is: 1. RTA and RTB connect with each other using back-to-back connection with serial PPP connection, and use the asynchronous interface as the backup interface. 2. And on each router there is a ethernet interface as a stub network. All the networks run ospf and belong to 3 areas respectively. PPP and its backup links are all in the area 0. 3. I have use the broadcast key word in the rout map, and correctly define the dialer-list with ip permit. Question: When the primary PPP link is down, the DDR works correctly. But there is not hello packet can be find on the DDR. When I show the interface asynchronous 1 under the ospf, I find that: no hellos (passive interface). What is mean? OSPF Hellos are supressed over a dial-on-demand routing circuit. Why? can not explain it. Can you help me? Reason - the only information that should travel over the demand circuit are real data and routing changes. Once the link is up, OSPF assumes it's reliable and suppresses Hello's so that the Hello's don't cause the circuit to stay up all the time. If you have Internet access, search the Cisco website (www.cisco.com) for OSPF Design Guide for a more detailed explanation of demand circuits and virutal links and other important OSPF qualities. _ Do You Yahoo!?

Re: Frame relay problems [7:28569]
Does anyone know why I am seeing active pvc's on this hub and spoke frame relay config and only getting half succesfull pings. I had to delete the yep. remove the frame map statement and disable inverse arp on s0 of r4 (it's causing your failures from/to r1) For r3, I'm assuming you can ping 172.16.1.1, so the pings aren't 'turning the corner' from sub-int to sub-int. do a debug ip packet on r3, and see if you get 'encapsulation failed'. If you do, think about what else you might need on s0 of r3 to get to r4. dlci and interfaces and then reload the router because I changed the interface type from point to multi.

Re: network simulator [7:27658]
Is there any router simulation software that I can configure to run in a Frame Relay and ISDN network ? cisco routers have the ability to simulate Frame Relay switches. The archives are full of examples, but www.cisco.com also has the configurations in a number of places. try searching for frame relay switch ISDN is a little different. There are a few different solutions. One solution is a device that has 2 ISDN BRI ports. This is known as an ISDN Simulator, or ISDN Emulator. These usually have S/T and U interfaces, and the cost is typically $1500, less if you shop around. Others have had success in using a PBX with ISDN interfaces. The 2600/3600 series cisco routers running 12.1 code has the ability to simulate ISDN BRI switching - note that this is a more expensive solution than the ISDN Simulator solution. see http://groups.google.com/groups?q=john+paul+morrisonhl=enrnum=8selm=0ZEk7 .131740%24B37.2967002%40news1.rdc1.bc.home.com (watch the URL wrap) Depending on where you live, it may also be economical for you to just order two ISDN lines for the time that you need to study ISDN. good luck in your studies -e- That which does not kill us only makes us stronger - Nietzsche _ Do You Yahoo!?

Re: How Good Labs go Bad (was RE: A very basic question : BGP [7:26495]
more below Jason Carnevale got me thinking that there are a number of ways that labs, even more than real-world configurations, go bad. I'd like to start a checklist of such things. 1. There is no return path for your test signal (e.g., ping, traceroute). Also a common real-world problem. 2. A given routing scenario appears at first to work, but fails as routers are added. The real situation was that dynamic routing never worked in the scenario, but you had connectivity through directly connected subnets. 3. Weird protocol combinations imposed by the limited number of routers in a lab, in which protocols are asked to do things they were not designed to do (e.g., IGPs between AS). Multiple levels of redistribution tend to fall into this area. 4. You do not see expected routes due to completely correct summarization or aggregation. 5. Classful versus classless interactions. The real world, at least as defined by the Internet, is classless. 6. Failure to specific ip subnet-zero. 7. Attempts to maximize summarization even if you pick up address ranges not intended to be part of the summary 8. Attempts to minimize the number of lines in a configuration, leading to confusing, error prone access lists, OSPF network specifications, etc. Additional suggestions are welcome, but try to make them general. 9. Ambiguous requirements in the exercise lead to multiple possible correct solutions, but in reality only one solution will work because that's the way the exercise writer designed it. 10. The software is buggy, so you might have a perfectly correct configuration only to discover that it doesn't work because of CSCpi3.14159. 11. Shotgunning a problem by adding/deleting configuration commands and leaving 'artifacts' in the configuration that cause the solution to fail until a router reload is performed to clear the artifacts. 12. Adding or changing commands that really only take effect after a reload is performed. 13. The interaction between different versions of IOS is unpredictable or, worse yet, broken. 14. The lab exercise is just plain wrong, or the solution given is just plain wrong. _ Do You Yahoo!?

Think about it for a minute (hint - summarization occurs most logically at EVEN sub-network boundaries...192.168.1.0 is an odd /24 boundary) many thanks in advance.. steve _ Get your FREE download of MSN Explorer at http://explorer.msn.com/intl.asp _ Do You Yahoo!?

Off-topic - Another Troublemaker (was Re: List Circuitbreakers [7:25929]
Why are you tracking people anyways? What do you have to gain? You getting paid by knowing peoples real name and company they work for? Maybe selling it to recruiters? Tracking - by request of the company that issues the certifications that are discussed here - read the Cisco Non-Disclosure Agreement. Most of the folks on this list have ethics and follow the NDA. Getting paid for knowing people's real names - That would be unethical. Paul's ethics are much higher than that. He has demonstrated that on this list. But I'd certainly question your ethics, based on what you've suggested here and in previous posts. You seem to be bent on making an intelligent point, so just make your point then leave. This list will survive without you. Read the charter for this list. You're the reason why my company uses this kind of secure internet service. It keeps people like you from snooping around our network. That's a personal attack on Paul, as were the others. Perhaps you need to do some data collection prior to making general accusations, like a rational adult would do. Also I never attacked you personally and don't know why you attacked me. It just seems that you would be smart enough to make some cash off your site. No need attack me for making a wrong assumption.

Re: Static Routes vs. Dynamic Routes [7:25059]
If I'm looking at the routing table in a router that I did not configure, how can I know that a static route is a floating static route and not just a run-o-the-mill static route? S network/masklength [AD/METRIC] how-connected, where AD is administrative distance by the administrative distance displayed in the routing table: sample routing table: S 10.1.1.0/24 [0/0] is directly connected, Serial 0 S 10.1.2.0 [1/0] via 10.1.20.1 S 10.1.3.0 [200/0] via 10.1.2.1 the corresponding routing statements in the configuration would be ! the default directly connected administrative distance is 0 ip route 10.1.1.0 255.255.255.0 serial 0 ! the default administrative distance is 1 for a next-hop static route ip route 10.1.2.0 255.255.255.0 10.1.20.1 ! when an administrative distance is indicated, it takes its place in the routing table. If the administrative distance is too low, it will override dynamic routing protocols and not 'float'. If there's another exactly matching route in the RT with a lower AD, the static route won't be displayed in the RT ip route 10.1.3.0 255.255.255.0 10.1.20.1 200 Thx Todd Carswell _ Do You Yahoo!?

Re: Why can't I ping my own interface address? [7:25040]
This happen often when there is duplicate address. Make sure you do not have a duplicate address. Some times even when you remove the duplicate address, you still need to restart the interface. Also, oftentimes, it means that there's no return route for the ICMP reply from the target PINGed address. I am not being able to ping a local interface on a router. The encapsulation is default and is connected back to back on a serial interface to the next router. The output of show interface shows that the interface is up.

Re: ISDN backup will not activate [7:25129]
I've seen the other replies to you post, and I'll give you a few other pieces of input. By the way, you really didn't give us any indication of what you saw as the output from the router - I'll just assume that you saw nothing. 1. From the configuration, it is not obvious what kind of ISDN switch you're using. Do you know if you need to add a statement to define the switch type? (I'd guess yes, unless the rules changed in 12.2) 2. Someone else indicated that you need to check the ISDN status using the appropriate show command. You'll learn something from doing that check. Mostly, you'll learn how to read the status of the ISDN circuit, and what the different fields indicate on the results of the show isdn status command. Learning the debug commands (debug isdn q921, debug isdn q931) are also valuable tools. Learn to use them to diagnose a problem. 3. Look at the purpose of the dialer map statement. Someone else indicated that you need to configure a destination phone number for that. I agree with that indication. Paris doesn't know what number to dial to reach New_York_City. 4. Someone suggested using backup-interface. I'd counsel you NOT to go down that road until you have the point-to-point ISDN configuration stable and it's coming up when you want it to. 5. Another person suggested that you add an administrative distance to your static route. That would be a good idea. When you do that, your ISDN circuit will come up only when the route for the serial link goes away (assuming that it's the only route to the other router) 6. Some switches prefer/require that you suffix the dialing numbers to the SPID assignments. Learn which switches need that kind of input. 7. What other resources have you used to learn configuration of ISDN? There are different layers of ISDN configuration. They are, in order of bottom to top: a. the ISDN physical connection itself (S/T interfaces require NT-1's or a simulator that has an S/T interface, U interfaces have a built-in NT-1) Cisco 2500 series routers (except the 2524/2525) have an S/T interface. The 2524/2525 has two flavors of modular BRI, S/T or U. Cisco 4000 series NP-4B and NP-8B have S/T interfaces. I'm not sure about the 26/3600 series, but I'm sure someone else on the list does know and might be willing to share that info. b. ISDN interface establishing communication with the ISDN switch (q921 signalling - requires the correct ISDN switch type configured and the proper physical connection) c. ISDN interface obtaining TEI (q931 signalling-requires the ISDN SPIDs configured properly) d. triggering the interface to dial (either IP or backup-interface or snapshot routing, requires the dialer-map and dialer-lists configured properly) e. encapsulation negotiation (ppp-requires both routers have a common encapsulation) f. authentication (chap-requires username/passwords used in the dialer-map statements match on both routers) g. IP routing (static or dynamic routes) over the interface (requires routing protocol including static to route to the correct destinations via the BRI interfaces). h. establishing multilink (requires the dialer-load statement) 8. Extraneous commands in a BRI configuration sometimes spell disaster, so take out anything that you don't absolutely need from a basic's perspective. Otherwise, your configuration is a good start. Unfortuately, incomplete BRI configurations don't work, and don't give you any indication of why they don't work. I'll refer you to a very valuable resource, which I still use when I get stuck on an ISDN configuration. It's Cisco's TAC page for ISDN Technology: http://www.cisco.com/pcgi-bin/Support/PSP/psp_view.pl?p=Internetworking:ISDN (watch the URL wrap) Here's a page with a very basic configuration that you can learn from, step by step: http://www.cisco.com/univercd/cc/td/doc/product/software/ios121/121cgcr/dial ts_c/dtsprt3/dcdbri.htm (watch the URL wrap) ISDN is a very complex configuration until you've mastered the basics, which means understanding the different layers of BRI configuration. I'd suggest that you study these pages, and then if it still doesn't work, c'mon back and post the configurations from both routers and the results of some of the show commands that you'll learn from reading the basic's pages. Good luck in your studies, and let us know what you learn about ISDN. -e- - Original Message - From: nettable_walker To: Sent: Friday, November 02, 2001 5:27 PM Subject: ISDN backup will not activate [7:25129] 11/2/2001 4:30pm Friday Professional's, I would like to get traffic from Paris to use ISDN when the primary link goes done.

You have the following route filter configuration: Router bgp 100 Network 172.16.0.0 mask 255.255.0.0 Neighbor 172.16.3.1 remote-as 100 Neighbor 172.16.1.1 remote-as 100 distribute-list 1 out Access-list 1 deny 172.16.5.0 0.0.0.255 Access-list 1 permit 0.0.0.0 255.255.255.255 There is a diagram and 172.16.1.1/24 is on Neighbor 2 and 172.16.3.1/24 is on Neighbor 1 It then says that the above configuration does the following: The use of the distribute-list command and access-list 1 prevents the BGP routing updates from neighbor 1 propagating into neighbor 2's routing table. Also, in the diagram Neighbor 1 (172.16.3.1/24) is connected to 172.16.5.0/24 so to me is seems like there is a typo in the book and instead of having the config line read: Neighbor 172.16.1.1 remote-as 100 distribute-list 1 out I think it should read: Neighbor 172.16.3.1 remote-as 100 distribute-list 1 out This would then make the above statment correct in saying that it prevents the BGP routing updates from neighbor 1 propagating into neighbor 2's routing table. Please let me know if what I am saying sounds correct based on the above information and that it is in fact a typo, or if maybe I am just not understanding it correctly.

To: Sent: Thursday, October 25, 2001 1:03 PM Subject: RE: Passed CIT today! Now a CCNP [7:24099] Ok. I just want to clarify something since a couple of people have emailed me off list asking how I think an MCSE is going to help me attain my CCIE. :-) The short answer is, I don't expect it to help me attain the CCIE. My thought processes on this were varied. Mainly, I know I am nowhere near ready to attempt the lab. So why spend $1250 when I know I am not ready? I did not mean to imply that I am going to stop with Cisco. Quite the contrary. I have a home lab which I intend to continue working on. I also have my job which requires me to keep up with Cisco. But in my job, what I tend to find is there are the server people who know the server end really well. And there are the Network people who know the Infrastructure and the routing equipment really well. But there are not too many people who can troubleshoot from end-to-end. I want to be one of those people. There are also a lot of companies which are migrating to W2K, including the company I am at right now. We have had a lot of issues with this. (Which, of course, keeps getting blamed on the switches!) :-) But that is another story. On another note, I wanted to plug some great resources I found for learning to analyze traffic with a Sniffer. I don't have any vested interest in these books. However, since I have been searching for quite some time for some good reference material for learning sniffer and have had a hard time finding any, I was quite happy when I found these. They are published by http://www.podbooks.com and are written by Laura Chappell. I have the TCP/IP Analysis and Troubleshooting which I bought from Amazon.com for $66. However, I have since found that podbooks sells the set of 4 directly on it's website for $99. So I am probably going to purchase those and slap this one on Ebay. :-) They have really been good at explaining how to analyze a packet trace. I already knew how to do a basic capture, but analysis was another story. I just thought I would mention these in case anyone else out there was in a situation like mine. Stuck in a job that won't pay for training, but wanting to learn packet capture analysis. I had not seen these particular books mentioned previously. Heather Buri _ Do You Yahoo!?

Re: Resolved, was OSPF Virtual Link Authentication [7:23867]
Also, I suspect there are more of these kinds of problems with 12.x images. My favorite is the one where you plug a cable into a port, set up your layer three, and nothing works. All the configs are correct. A reload corrects the situation. Starting with 12.x, the router does hardware checks, and if there is no cable plugged into a port, the router considers that port down. adding a cable and layer three later gets you at best an up down situation. I have seen it happen where you get up up but no layer three works. Reload, and all is well. did toggling the interface solve the problem?

Re: Help in setting up a lab!! [7:23836]
Here goes a simple question that will help me out a lot from now one.. I just bought the following equipments from a company that ran out of business: 4 2511 3 AS2511RJ 1 2501 3 catalyst 1200 (older than my grandma!!!) Your grandma is only 9 years old? ;-) of course, the 'Crescendo' 1200 was 2 generations of switch ago... I heard that the IOS of the 1200 is similar to the 5000 , that is much more expensive!! All of them are running 11.x and has 8MB flash I have got most of those cables like the octal (2 of them) and I have to get some back to back cables. I am working towards my CCNP and future CCIE and I would like to know what else should I buy to make my lab or labs up and running. And how much would that cost to me??. You might want one more router with 4 or more serial interfaces so you can simulate a frame relay network. A 2521, 2523, or Cisco 4000 with an NP-4T, and you could conceivably get one of either for $500. A little more flash wouldn't hurt you either - 8 8M flash simms would be great (crack the cases to see if the routers have an open flash SIMM slot because your 8M flash could be made up of 2 4M flash SIMMs) I also would like to setup a lab where people could telnet in .. If you set up one terminal server that is accessible via the Internet and connect the async interfaces to the console ports of the other routers, you'll have that handled. _ Do You Yahoo!?

Re: Switching exam question [7:23497]
so the risk of a bridge loop is better than a recalculation of spanning tree ;- sure, especially when you KNOW you're in a loop-free environment. of course, my motto is spanning tree bridging, don't leave home without it. I've seen goofy things happen without spanning tree or with partial spanning tree running in a looped environment. (don't ask about 'partial spanning tree' - I still can't figure out how they did that and why) And I've seen goofy things happen with spanning tree in big redundant environments, especially with respect to not being able to control which ports get disabled in a loop path. The morale of the story there is the path you want to have disabled (the redundant one between switches) will always be enabled, and vice versa (as in the uplink to the router will be disabled). _ Do You Yahoo!?

Re: Design Question - Spanning-tree Protocol. [7:23614]
Hi Folks, I have a design in which Cisco 3548 XL's are GBIC-stacked on various floors of a campus and are uplinked to a core Cat 6509 switch. The uplink from every floor stack is ether-channeled to the core via two parallel equal-cost paths. One uplink path starts forwarding and the other goes into blocking mode from each floor stack. Here is my confusion... If only one link of a 400 MBps full-duplex ether-channel fails from the forwarding path , will it invoke spanning-tree recalculation ??? Or will the 'now' sub-optimal path still remain in forwarding mode and the now more-bandwidth path remain in blocking mode ??? the 'suboptimal' path will continue until all the links fail. At that point, STP will detect the link failure and recalculate. Since spanning-tree recalculation causes a lot of ripples throughout the switched network, I would assume that the latter were true. However, I would like to hear views from people who would think that the former scenario is more probable. Thanks very much. Aziz _ Do You Yahoo!?

Re: default-routes for eigrp?? [7:23581]
Tried that...first on the border router thinking that it would inject a default route to the remote router..on the remote router shows as candiate route * But does not work..(This command works for RIP BTW) The key concept here is HAS TO BE IN THE ROUTING TABLE. Otherwise, the default-network command merely injects a static route into your configuration which is usually useless. Thus, if the default route were out of the 209.125.17.0 network, the statement ip default-network 209.125.17.0 would allow that route in the routing table to be flagged as a candidate default route, and would advertise that route to other eigrp routers.

Re: How to upgrade the IOS of C2521?! [7:23498]
Hi all, As a beginner, i am setting up home lab. Can anyone give me the detail procedure of how to upgrade the IOS of C2521. I'm assuming you have the console connection to the routers. I'm also assuming you have either learned to clear the passwords, or that you have enable (priveleged EXEC) access to the routers because you know the passwords. So from priveleged EXEC mode (the prompt that looks like Router#, not Router) 1. use the s0 or s1 serial interface of the 2521 to connect to the 2503. (those are the high-speed serial interfaces) 2. set the clock rate to 400 (the clock rate will be set on the router with the DCE cable connected) - example configure terminal interface serial0 clock rate 400 no shutdown ^z (control-z. typing end also takes you out of configuration mode) 3. set an IP address on both serial interfaces to be in the same subnet, and enable the ethernet interface - example on the 2521 - config t interface serial 0 ip address 192.168.1.1 255.255.255.0 end on the 2503 - config t interface serial 0 ip address 192.168.1.2 255.255.255.0 no shut int e0 ip addr 192.168.2.1 255.255.255.0 no shut ^z 4. create a default route on the 2521 to the serial interface of the 2503 - example ip route 0.0.0.0 0.0.0.0 192.168.1.2 5. ping the 2503 ethernet interface from the 2521 to verify connectivity - example, if the ethernet were set to 192.168.2.1 ping 192.168.2.1 6. save the configuration on the 2521 wr mem (or copy run start) 7. depending on where the IOS image resides, you want to start up the tftp server on your PC, or set up your 2503 as a tftp server (if you want to use the image that resides on the 2503) - example on the 2503 - show flash (a filename will be displayed - perhaps something like c2500-d-l.120-9.bin) conf t tftp-server c2500-d-l.120-9.bin ^z 8. on the 2521, copy tftp flash at the prompt for the ip address, either use the ip address of the PC running the tftp software (it should be a 192.168.2.x address) or the serial interface of the 2503 if you're copying that image at the prompt for the source filename, use the filename that you used above - in this example, c2500-d-l.120-9.bin at the prompt for the destination filename, press enter for all the other prompts, press enter or y then watch the flash get erased on the 2521 and then watch the tftp transfer process with all of the exclamation points (!) When the image is finished tranferring, the 2521 will reload, because it runs its operating system from flash memory. Good luck, and have fun -e- I got no problem with my C2503 because it has a Ethernet port for me to connect the PC to it. Kenneth _ Do You Yahoo!?

Re: network programming? [7:23377]
Here is my story I have been taking 'C ' programming for the last 2 months at the local college and I need some advice on what languages I should learn, or master, so I can become a network programmer? To me a Well, in the olden ancient days (about 15 years ago or earlier) the answer would have been 'machine code'. But since y'all don't study that anymore, that's a moot point. Nowadays, source code can be transported and compiled on almost any system, so the languages that are closest to the hardware and the most effieient are the best bet. I don't know how 'bloated' C++ is, but C used to be a very compact language when it got compiled and linked. network programmer would be someone that either programs network hardware, such as routers and switches, or possibly someone that writes drivers for network products, or creates network management software, or something along those lines, that is OS independent. I know that if you Not so true anymore. Network programmers are needed at the application level too, above the driver level. Because most applications are 'network aware', coding those apps to work over a network (as opposed to memory or local disk storage) is an important aspect of the performance of the code. Many of us network engineers grimace at the network resources (high bandwidth, low round-trip latency, 'do not accept fragmented packets', small data packets, highly interactive and high frequency chattyness between client and server or between servers, etc) required by some of the software out there for good reason - the programmers treated the network as an unlimited private resource rather than a shared limited bandwidth resource. A couple of good network programmers involved in the development of that code would have been a great help in those cases. want to write for Unix , you should learn C very well, but how about if you wanna code for routers and switches or embedded systems. Should I focus on C++ more so than C??? I want to go into an area where job stability is important. I don't necessarily want to work for the same A area where there is job stability, eh? Have you considered owning a convenience store, or some sort of civil service? Those two are probably pretty stable job areas. High tech is notoriously unstable. We could probably take a poll on this list to see who has ever been RIF'ed (laid off). I'd raise my hand as a 'yes' to that question. At least twice. In 15 years. company most of my life I just want to learn a language ,or two, that are relevant, so that if I need to leave I can get a job working on similar projects.

Re: OSPF inter-area learned routes [7:22268]
OSPF (Open Shortest Path First) calculates the shortest path to area 0 first, then the shortest path to the next area boundary via intra-area routes. The best illustration of this was in the Networkers 2000 CCIE Power Session presentation http://www.ieng.com/networkers/nw00/pres/3304/3304_c1_sec2.pdf p 16 hth... -e- - Original Message - From: Ian Schorr To: Sent: Friday, October 05, 2001 1:49 PM Subject: OSPF inter-area learned routes [7:22268] Okay, I've been beating my head over this one for a week, and finally give up: I'm trying to understand the logic behind OSPF's and Cisco's routing selection behavior in this instance: I have 6 routers, segmented into 3 areas - areas 0, 1, and 2. Routers A1 and A2, which sit in area 1, have fast ethernet interfaces on the same network (we'll call this network A), have formed adjacencies with eachother across this network, and seem to be exchanging routes properly. Routers B1 and B2 are in areas 0, 1, and 2. Again, each router has a fast ethernet interface on the same network (network B), which is in area 0. B1 has a T3 link to A1, and this numbered link is in area 1. B2 has a T1 link to A2, and this numbered link is in area 1. Routers C1 and C2 sit in area 2, and have fast ethernet interfaces on the same network (network C). B1 has a T1 link to C1, and B2 has a T3 link to C2. Pretty much everything else is default, including link metrics, summary metrics, etc. No summarization is taking place. Now, I'm confused, because if I do show ip route on router A1 or A2 for network C, the selected inter-area route for network C points across the T1 link to B2, as opposed to the lower-cost path across the T3 to B1 (then across the FE link to B2, and across the T3 link to C2)! If I do a show ip ospf database summary for network C, I do see that I've received summary routes for network C from both B1 and B2, and that B1 has a lower metric, but it seems that the A routers select the path across to B2 anyway. I assume that this has something to do with the fact that the core routers are both backbone routers AND ABRs for the other areas, and that LSAs for area 1 don't pass across the fast ethernet interface (instead, I expect to see summary-LSAs for the area 1 passing across area 0, then being re-summarized as available paths back to area 1), but I suspect that there's just something fundamental about OSPF that I don't understand. Can anybody explain to me why the better-metric path isn't being selected in this case? Thanks, Ian Schorr CCNP _ Do You Yahoo!?

I have not looked at the ATM or the OSPF sections yet. These cover quite a few pages, and may offer more detail. there are two sections - one for note, the other containing configuration examples. both sections suffer from the same shortcoming. in particular: NTP - virtually nothing in the way of detail or explanation. nothing regarding authentication, for example. no detail on the difference between NTP peers and NTP client / servers, and more importantly, why you would use one or the other. Filtering - nothing direct. have to find information indirectly, under things like route-maps and prefix lists. distribute-lists are not covered at all. route-maps - again, pretty basic redistribution - this is a major Cisco core topic, yet this guide offers very few real tips. tunnels - very rudimentary. Otherwise, in general, I have not found much in the way of clarification of complex points. My impression is that a lot of these notes are *'s that the author wrote in his personal study book as he was going along. I am doing something similar as I go through things. in reviewing, I find that my own written word does not cover anywhere near what I have discovered as I work. I tend to * the gotcha's, which in turn trigger associations with the things I have learned. I suspect this guide is more a compilation of these kind of sentences.

Re: NAT and Telnet [7:20362]
Guy...yes, you're correct - I mapped port 23 on the outside to 23 on a loopback... and one of my study buddies just called and told me it's a new 'feature' of 12.1 and higher to deny incoming on the outside interface. Some firewall feature gets enabled that prevents inbound telnet to the outside interface unless that 'conduit' is opened using nat inside source static. I might downgrade to 12.0 tonight to see if that's true. -e- - Original Message - From: Lupi, Guy To: 'EA Louie' ; Sent: Wednesday, September 19, 2001 2:03 PM Subject: RE: NAT and Telnet [7:20362] Did you have to map port 23 of the outside interface to port 23 of the inside interface?

Re: NAT and Telnet [7:20362]
reason = security. If you market NAT as a security-type protocol (gasp!), then to allow telnet into that address without 'express written consent from major league baseball is strictly prohibited'.

If yes how ? 1. yes, it's possible. 2. yes, I've done it 3. by a. setting your crypto access list on R1 to encrypt both LAN1 and LAN2 traffic to R3, and LAN1 and LAN3 traffic to R2. b. making sure that your routing is set up properly so that LAN2 traffic to LAN3 is routed via R1 and vice versa. also see http://www.cisco.com/warp/public/707/ios_hub-spoke.html Thanks, pat __ Terrorist Attacks on U.S. - How can you help?

I want to implement multihoming for one of my clients and I do not want to use BGP at all neither do I want to ask each of my upstream providers to route the other provider's Set of IP Addresses given to me, through its own Network. I have two Routers called RouterA and RouterB. RouterA have three ethernet ports (EA1, EA2 and EA3), while RouterB have two ethernet ports (EB1 and EB2). My two upstream providers (ISPs) are Source1 with IP address 63.98.9.0 255.255.255.0 and Source2 with IP address 100.10.10.0 255.255.255.0.
