DSL, ISDN's new and improved cousin may be superior in quite a few number of ways, but sometimes you have NO other choice but to use ISDN to access some far off places. Maybe this is changing soon and they will phase it out, but ISDN still seems fairly important, for say PRI deployments. Cannot think off the top of my head why a PRI would be better than a T1... but some clients I know still have them. Not sure if ISDN falls off to the old technology that should never be deployed nowadays (at least BRIs, nevermind multichassis/multippp bonding for now).

Re: VTP Domain Server Question [7:70942]
Ronnie Higginbotham wrote in message news:[EMAIL PROTECTED] Once you take the VTP server down all vlans will basically go down. Which will bring down the network with only one VTP server. They will sit there and do nothing until the vtp server comes back online. Is this right? I got to wondering about this, but I don't have enough equipment to simulate a real network to test end to end. What I did do was take my two switches, set one as the VTP server, the other as the client, create some vlans on the server, assigning those vlans to ports on the client switch, shut down the trunk ports between the two switches, and watch. I'm not sure how long I need to wait, but what I am seeing ( or not seeing ) confirms my suspicion - that the assigned ports on the client switch remain functional. My trunks are down on the client switch, but that is expected in this setup. What I am unable to test is whether or not the trunks, over which vlan information is propagated, will still function in the scenario described. I suppose you are correct when you say that all vlans will basically go down. Certainly, in my simulation, no one on a local switch could get to the core. What I am wondering is in a dual core switch situation as described, if servers and services were dual homed to the redundant switches, if all would remain well. Certainly no new vlans could be added, but I'm wondering if all else would remain functioning. some info on the switch Switch_48#sh vtp stat VTP Version : 2 Configuration Revision : 2 Maximum VLANs supported locally : 1005 Number of existing VLANs: 12 VTP Operating Mode : Client Switch_48#sh vlan VLAN Name StatusPorts - --- 1default activeFa0/4, Fa0/5, Fa0/6, Fa0/7 Fa0/11, Fa0/12, Fa0/13, Fa0/14 edited for brevety 10 VLAN0010 activeFa0/10 20 VLAN0020 activeFa0/20 30 VLAN0030 activeFa0/8, Fa0/30 40 VLAN0040 activeFa0/40 100 VLAN0100 activeFa0/1 200 VLAN0200 activeFa0/2 300 VLAN0300 activeFa0/3 1002 fddi-default active 1003 trcrf-defaultactive --M Switch_48#sh int trunk Switch_48# ( demonstrating that the trunk is down ) As I said, with two switches, I can't test a real world.

Can anyone provide info in a more realistic simulation? It would be a good idea to have two VTP servers so you can take them down one at a time and upgrade. always a good idea. I must assume the 2 6509's or for you core routing and the 4006's are your closet access switches. If the other standby 6509 is a client in the same VTP domain as you server which I don't see why it would not be, they already that the same VTP revision all you have to do is promote the client 6509 to server. set vtp domain (Domain Name) mode server Then you have two servers.

I am working with a network configuration that has dual 6509's as core switches. One is the VTP domain server, the other is a VTP domain client. All other 4000 switches are defined as client also. I need to take both 6509's down to upgrade the Cat-OS on them, however I am concerned about what happens to the other switches when the VTP domain server goes away while the other 6509 is in client mode. I know that I can assign multiple VTP servers to a domain. My original thought is to first make sure that the client 6509 is running the same VTP revision # as the server 6509. Then I should be able to change the client 6509 to VTP server mode. Then in theory either server can take over VTP responsibilites, because one will be able to act as the other if the other one goes away. What I was also wondering, do all VLAN's go disabled if I were to only have a single VTP server and shut it down when the rest of the switches are clients? If so, would this happen right away, or after 5 minutes? If I take the 6509 server down, it will not be able to tell anyone that a topology change has occurred, but will the clients be looking for the VTP 5 minute updates?

Mobile IP Test Scenario [7:70891]
In the idol speculation category at this time. Just mulling ways to familiarize myself with Mobile IP the idea is to use my computer to simulate a roving user who still needs to get to the internet. here is what I came up with for a test bed: Internet | outside_LAN ( public IP side ) | firewall | | firewall IP = 192.168.1.1/24 | inside_Lan ( 192.168.1.x/24 ) | | router ip = 192.168.1.2/24 | router_1\ | \ \ frame_relay_cloud--- ---Router_4 / \ | | / \ router_4 ip = 192.168.4.1`/24 |/ \ | Router_2 router_3 VLAN_4 = 192.168.4.x/24 | | | Router IP = 192.168.2.1/24 router_3 ip = 192.168.3.1/24 | | VLAN_2 = 192.168.2.x/24VLAN_3 = 192.168.3.x/24 hope the ASCII art survives the groupstudy message mangler :- In any case, this being done via the magic of a switch, I can easily move my computer from vlan to vlan just by changing the connection to the appropriate port. At least, that's the theory. Router 1 is the home agent routers 2,3, and 4 are the foreign agents. The idea is to simulate a wireless network, in which a user is wandering from AP to AP, with the particular APs in different subnets, as might be the case in a hospital or a business occupying multiple floors or multiple buildings in a campus. If mobile IP works the way it is advertised, the roving user can still surf the web, no matter which part of the network he occupies. not changes required on the user station. I probably won't be able to test this prior to next week. Too many other things going on right now. Just wanted to offer this as food for thought, if anyone out there is looking for some study ideas.

A lot of low-end switches don't do STP either. Yet they filter out BPDUs? If they don't, then assuming proper configuration on the high end switches, can there be really loop? So, the access point would have to be inserted into the network just right so that it caused a loop, but that's certainly possible. In that case all the looping broadcast traffic, not to mention looping unknown unicast traffic, could bring a network to its knees. I'm surprised so many people doubted his decription of the problem!? A 6509 can switch multiple gigabits of traffic without any problems. You would need quite a few wireless loops to kill such a box. I might be missing something but I still doubt that a user with an integrated wireless and LAN NIC can kill bring down a network of 6509 and 3550 switches. Not knowing firsthand, I've checked the Cisco documentation. For the 1200 series of AP's, at least, I can find no reference to spanning tree. Not saying it isn't there. Just saying I see no reference. every AP with which I am familiar has but a single ethernet port. It is essentially a hub, although some of the vendors have some pretty sophisticated capability build in as part of their firmware and OS. I've been working with Proxim on a deal, with 802.1x port based authentication. The particular Proxim device creates virtual ports for end stations, and communicates with radius to ensure that the user can authenticate against the 802.1x database, even as the user moves from AP to AP. It is not inconceivable that putting in a series of wireless AP's could create a loop somewhere. Particularly if there are rogue devices out there and someone is wandering among them. Just thinkking out loud, but the switch would see a user MAC comming into different ports as the user moved around. Thinking out loud again, with an authorized and reasonably thought out wireless installation, all your AP's would be in the same subnet/vlan and users wandering from AP to AP would cause no problems becasue to the back room switch the user mac would be on the same vlan as it moves. as far as the switch is concerned, nothing untoward has happened. Unless something is terribly wrong - i.e. major bug in the AP software - users cannot be connected to more than one access-point simultaneously ( if they could, that might cause loop problems ) generally, the wireless nic firmware negotiates connection to the AP with the strongest signal in a mobile situation. Once in a while I see a comment that leads to believe that there may be some misunderstanding about the term bridge when used in conjunction with wireless. A wireless bridge is a device for point to point wireless communication with another wireless bridge. It is more like a serial link than what most folks think of when they hear the term bridge. one of those newfangled terms that is in the purist sense misused, but neverless is used differently than in the world of switches. So, one way for wireless, with it's single ethernet port, to create a loop would be for it to bridge to anther AP, which in turn is plugged into the same switch. Loops would form and the ensuing broadcast storm could wreak havoc.

The most recent number I've seen is 11757. Which, averages about 170 people per month. Extrapolating to October, the number of people passing from Oct 2002 to Oct 2003 should turn out to be around 2044. My conclusion then, is that since the labs stay booked, and since the expected doubling of the people passing has not occurred, that the new lab is somewhat more difficult than the old lab. Therefore, the difficulty barrier was increased to partially, but not fully, counter the effects of lowering the quantity barrier (number of lab seats). Had the difficulty been raised enough to fully counter the quantity barrier, the number of those passing would have been held constant. Actually, I believe your numerical analysis is somewhat incomplete. At the same time that Cisco made the change from 2 days to 1, Cisco also (quietly) eliminated weekend testing. Also, Cisco has lately banked some test locations (i.e. Halifax). Finally, anecdotally I've been hearing that the number of empty seats in any particular location seems to be higher than it was in the past. For all these factors, I therefore don't think that there has been a true doubling of seats. well, first of all, yes I saw a number of empty seats last two times through, but don't forget - there are a hell of a lot more racks as well. I believe San Jose doubled the number of available racks from 10 to 20 ( and don't rag on me if I am wrong about the specifics, please. I have to go from memory here. ) the only people who can provide true statistics are working for Cisco, and believe me, they ain't talking. then there is the bad economy factor. I haven't checked lately, but when I was looking a few months ago, it was no problem to find open slots less than 30 days out. if it is true that there are 150 people passing per month ( and I don't know because I haven't been keep stats lately ) then the conclusion is that test takers are just better prepared, for whatever reason.

Works nice. I just put in a Lynksys here at home. My wife and kids get great reception in the living room and various bedrooms, and even on the back deck. ( the AP is in the living room ) but I get jack here in my home office / study, and I am not more than 100 feet away ( and a couple of walls ) as the crow flies, so to speak. there is anopther room in the house where I can get real slow link if I am sitting on the floor, but if I stand up I get 54 mbs ( I bought the wireless G, as you can tell.) One office will have only 1 pc and the other will have 4.I figured wireless would be the easiest way to go since runing cable from our equipment to these offices would be a nitemare. I picked up an 802.11b (Linksys) access point and patched it through to my switch,set the SSID,and derived a wep key.The office with 4 devices in an attempt to save money bought an 802.11b (Linksys) access point as well.I provided their admin with all pertinent information (SSID,WEP key,IP\mask)and the access points do not seem to associate.Now I am by no means well versed in wireless but I assumed that as long as the SSID,WEP keys,and IP information was correct it would work.Im not sure what my problem is here and Im at a loss. you can configure the Lynksys as either an AP or a bridge. An AP is for communication to end stations. Bridges talk to other bridges. You want to make you new friends part of your own network? Bridge, assign them IP's from your network, and go for it. But I gotta say, you ( and your boss ) need to do a little bit of thinking. There are many ways to share the internet connection without opening up your internal network to the risk present by allowing strangers to use your connections.

Re: EIGRP OSPF DUAL MUTUAL REDISTRIBUTION [7:70643]
Jason Viera wrote in message news:[EMAIL PROTECTED] Can't figure this one out. I am mutually redistributing eigrp into ospf (dual redistribution points) and vice versa, I also have a separate redistribution point in the eigrp domain which introduces external (AD170) routes into the Eigrp domain, upon redistribution into OSPF these (external eigrp) routes are given an AD of 110, creating suboptimal routing. The only solution I could devise was based on modifying the distance of the external routes in the eigrp domain. What would be the best approach to tackle the problem, Any insight would be greatly appreciated!! Thanks Jason A couple of things come to mind. Distribute-lists assuming your routing domains exhibet any kind of rational organization, you could filterthose routes wihich are re-entering and being trashed by the lower OSPF admin distance. Prefix-lists also assuming there is some rhyme and reason to the domain organizations. I've gotten to where I like prefix-lists better than distribute-lists. As with anything networking, their usefulness depends on a lot of things. Route-maps similar to distribute-lists can use an access-list or a prefix-list as the seed Route tags ( used with route-maps ) gets a little trickier. your access-lists have to be right on. assign a tag value to routes coming in from one domain into the other, then filter those at the other redistribution point. come to think of it, you may be able to tag the routes coming into either domain using the redistribute command switch. (checks CCO) yeah, looks like it. You could also filter from EIGRP into OSPF by filtering EIGRP external routes - this would block routes that originated with OSPF from gong back into the domain. Not that it matters a lot because of the admin distance. A better way would be to filter OSPF external routes from entering the EIGRP domain. This can cause havoc if you have an ABSR somewhere and need those externals to get to EIGRP. gets complex fast, doen't it :- depending upon the level of expertise for which you are sudying, you may want to have all of these tools as part of your bag of tricks. never can tell when they might be useful.

Re: NTP on Cisco routers [7:70408]
Irwan Hadi wrote in message news:[EMAIL PROTECTED] Hi, I'm just curious how many NTP clients can a Cisco router (Catalyst 6509) serve? Well basically when Cisco Router is configured to synchronize with a time server it will automatically becomes a time server too (unless configured otherwise) right. Since it becomes a time server, then other routers and switches can synchronize their times by using NTP with this router. My question is if the desktops also synchronize their time with this Cisco router, until how many boxes it can serve before it collapse? Will there be any effect to the router if the router serves a lot of NTP clients? It would depend on what other tasks the particular router is charged with. How many routes in the routing table. The associated route processing overhead. Other processing, such as forwarding, etc. Isn't there another thread going on right now covering these kinds of variables? If all the router is doing is providing NTP, then obviously it could do more than if it were also your OSPF backbone ABSR router and you had 3000 routes and a number of them were flapping and half your users were also downloading service pack 666 from Microsoft.

It's because it's too complicated for an easy answer. You'd have to talk to the IOS developers for a good answer. I have a training manual that was used to teach new IOS developers. I checked it. Although it talks a lot about memory management, it doesn't mention how much memory each route takes. For one thing, it would certainly depend on the routing protocol. EIGRP's scaled, composite metric takes more bytes than RIP's hop count, for example, although from what I learned about memory management from the developer training, memory is managed in chunks, so a few bytes probably wouldn't matter. Most of the routing protocols save more info than just the routing table. OSPF and EIGRP have a topology database, for example. So that would definitley affect memory usage. Also, unless you plan to save all of the Internet BGP routing table, it's simply not an issue. Routers have enough memory to store routing tables in most cases... So, it's not a very relevant operational questions?? If it's a research project, well get researching. Asking us won't help, I'm afraid. :-) or to put it another way, why bother when memory and CPU is relatively cheap ( you DO use 3rd party memory, don't you ;- ) As I tell all my customers, it doesn't hurt to max out the memory. Never can tell when you will need it. ( and it helps me retire quota ) As I say when I want to yank Priscilla's chain, design is dead. This kind of work is irrelevant.

Who I am has nothing to do with it. Why the ad-hominem attacks? Why can't people debate things simply on the merits of the argument, rather than calling into question people's motives? Hell, if you want to go down the road of ad-hominem attacks, I could just as easily say that all my detractors are or will be high-number CCIE's and so therefore all their arguments should be ignored because their motives are also questionable. But I don't do that. in general I respect your observations. I agree with this particular comment. I believe your own particular status is irrelevant. I believe the source is typical human nature. Just because someone has achieved something does not necessarily mean their observation or opinion is more valid than those of someone who has not. But human nature being what it is, many people tend to take the advice of someone with the numbers or letters after tha name as better than that of someone who does not. And when did I ever compare networking to a software company? Seems like a complete non-sequitur to me. About me 'devaluing' networking - how could I really doing that? Are you saying it's my fault that networking is devalued? Seriously. I am only 1 person. How could 1 person acting alone devalue networking in any measurable way? If I really had the power to manipulate entire markets like that, I'd be a multimillionaire and I certainly wouldn't be hanging out here on this ng. I think the real fear that people have is that I am not alone - that I really am telling the truth. If networking has been devalued, it is because the free market has decided that it should be devalued, and what is the free market but many individual entities all acting in their own self-interest? Therefore if networking has been devalued, it is because many people have decided that it be so. Not just me alone. you're NOT that powerful? How disappointing :- the job market is what you make of it. Yes there are external factors. In the grand scheme of things, comparative advantage comes into play somewhere along the line. I suggest that netwroking is to the point where fewer companies require on site support staff. They can outsource, colocate, purchase manged services, and in the end this means fewer staff jobs, and the remaining staff jobs requiring more expertise. Not saying it will happen tomorrow, but I can see the trend as well. About the cpa argument - I would argue that whenever the cpa test happened to be more difficult, then it would be more prestigious. Whenever anything is more difficult, it becomes more prestigious. Is that particularly shocking? Why is a degree from MIT more prestigious than a degree from Podunk Community College? Simple - graduating from MIT is harder than graduating from PCC. I even stated that if the CCIE all of a sudden got very very difficult starting today, then anybody who passed starting today

Re: number of CCIE [7:70151]
n rf wrote in message news:[EMAIL PROTECTED] Well, there are still less than 10,000 CCIE's. So the population hasn't accelerated THAT dramatically. Having said that, I will say that the CCIE has most likely gotten less rigorous and therefore less valuable over time. I know this is going to greatly annoy some people when I say this, but the truth is, the average quality of the later (read: high-number) CCIE's is probably lower than the average quality of the higher (read: lower-number) CCIE's. I respectfully disagree. True, there are more cheaters out there, and more practice labs, and the like. OTOH, Cisco is turning over the tests more often, and the test I saw a couple of mopnths ago was every bit as difficult as the one I saw a couple of years ago. The exam still seems to thrive on silliness ( build a six router network with every known routing protocol, and force any and all peering to occur through at least two redistribution points, while forbidding static routes, routes to null 0, and default networks, and by the way, all your /22's must be reachable in all of your classful protocol routers which are all /29's or /28's, and try to get anything to work with the bizarre combinations of physical interfaces and subinterfaces that we give you ) But IMHO the test is no easier today than it was three years ago, anyway. In fact, I think the case can be made that the test is more, not less relevant than it was for those with numbers in the 4000-6000 series, where there was still substantial emphasis on obsolete vendor proprietary protocols just another opinion, worth hat you paid for it ;- Before any of you high-number CCIE's decides to flame me, ask yourself if you were given the opportunity to trade your number for a lower number, would you do it? For example, if you are CCIE #11,000 and you could trade that number for CCIE #1100, would you take it? Be honest with yourself. I'm sure you would concede that you would. By the same token we also know that no low-number CCIE would willingly trade his number for a higher one. The movement is therefore all one-way. If all CCIE's were really created equal then nobody would really care one way or another which number they had. Therefore the CCIE community realizes that all CCIE's are not created equal and that intuitively that the lower number is more desirable and the higher number is less desirable (otherwise, why does everybody want a lower number?). Simply put, the test is not as rigorous as it was in the past, which is why lower numbers are preferred. Or, I'll put it to you another way. Let's say that starting at #12,000 Cisco makes the test ridiculously hard, putting in all kinds of funky technologies, and making the pass rate less than 1% or some other god-awful number. What would happen? Simple. Word would get around that the new CCIE was super-rigorous and therefore very prestigious to pass. Eventually, numbers greater than #12000 would be coveted, and everybody would want to trade in their number for one greater than #12000. Recruiters and HR people would start giving preference to CCIE's with numbers greater than #12000. The point is that when rigor increases, prestige and desirability tends to follow. When rigor declines, so does prestige and desirability. And what is the cause of this decline in rigor? Well, you alluded to several factors. While it is still rather controversial exactly how the switch from 2 days to 1 day impacted the program, it is widely conceded that it probably didn't help. Nor does having all these braindumps all over the Internet, and not just for the written, but the lab as well. The CCIE has certain arcane logistical rules that people have figured out how to 'game' - for example, for example, some people who live near test sites just attempt the lab every month over and over again. Finally, there is the consensus that the CCIE program has simply not kept up with the growing amount of study material, bootcamps, lab-guides, and so forth. We all know there's an entire cottage industry devoted just to helping people to pass the lab, and while there's nothing wrong with that per se, it does mean that Cisco needs to keep pace to maintain test rigor. To offer a parallel situation, when the MCSE bootcamps started to proliferate, the value of the MCSE plummeted because Microsoft did not properly maintain the rigor of the cert.

This is one case where it is absolutely essential to RTFM, and understand it, prior to attmpting an upgrade. And it's not like the FM is particularly clear, with several excellent examples.

Interesting way to spend a couple of hours. After reading previous posts on this topic, I entered the exam with a bit of trepidation. Never enough time to study.

There are only so many things that could be wrong, and only so many places those wrong things can occur, no matter what the protocol or topology. The good news is that test takers apparently are not required to know how to read sniffer traces ;- As for the 700 series nothing like that on the NP recert. The NP recert exam is one of the more updated newer exams with ios simulation for hands on testing. It is the DP recert exam that has all the old junk. Indeed, the CCDP recert exam is ancient, making you wonder what the point is. It can't be to show that the candidate is keeping up with new stuff!? ;-) I almost wonder if it's some sort of mistake. vision, policy, archtecture. definitely not the stuff of certification construction. CCNP isn't quite so ancient, except for the BCRAN part which is still ancient. I did get some 700 questions. But Routing and Switching were updated and did give Cisco proof that I was keeping up with new Cisco requirements. Routing included BGP and IS-IS, for example, which weren't on the test 3 years ago. One would think it would be easy to use the same pool of questions for CCDP, but they don't. No BGP or IS-IS for example. SNA and StrataCom though! Oh boy! :-) Priscilla Good luck..

Kevin Wigle wrote in message news:[EMAIL PROTECTED] Congrats Chuck and to continue the theme, I have failed the exam enough to get my money back guarantee from Boson. (in spades) However, today I passed it - which was good 'cause my cert was to expire on 8 June 2003. Now I'm good for another 3 years. I too am off to the CCDP recert. I'm due at the end of June. I had so much trouble I guess because I don't have nearly as much hands on as I used to. However, I question the usefulness of having to know the syntax of commands for different platforms when in the real world, a ? at the console will tell me that - no, don't use a hyphen. Hopefully people won't take Chuck's post as meaning that the exam isn't all that hard. Good 'ol Chuck has been around the block a few times on Cisco gear - eh Chuck? :-) It was hard, although maybe not because of the detail. Maybe having geared up for the CCIE lab more than a couple of times maybe I'm finally getting to understand some of this stuff. I must confess, three years ago I was awarded my CCNP on the bases of passing three beta tests and the old ACRC exam by a total of 25 points. The ACRC was the toughest exam I ever took at that point, and in terms of sheer terror, I'll stack it up against the CCDP and today's recert. So yes, I feel good getting through this one. Like I've really earned my cert. It never hurts to read as much as you can - from Howard, to Cil's books, to the various posts on this newsgroup, always with an eye towards learning how things really work. Yep - a couple of years of pounding the keyboard configuring routers for the CCIE lab didn't hurt. Hands on is good, and I like the direction cert testing is going. I just wish the res was better on the test screen. The exam is hard. When I certified I didn't try to pass the foundation to get there quicker, I took each individual exam. So I studied a focused area and then took the exam. This exam is the Foundation plus CIT and CCNA. Like getting CCNP with one exam. And back in my version 1 days, questions on BGP were just knowing how to spell it. Lots of BGP possible on this one. I used CCIE prep material to study as my old version 1 stuff was lacking. Everytime I took the exam I was surprised that I was still seeing new questions. Not just a few new ones but lots. The pool must be large on this one since it does cover everything. It has been suggested that a recert this difficult would perhaps strengthen the cert and make you feel good to have it. Well.. I think that there are problems with this exam. For me the only amusing parts were that what freebies were there were really simple. Those freebies should probably be deleted from the pool. But wait I needed those to pass! Guess I should be happy. Good luck to those who have to recert soon. Remember - your cert expires on the day you got it, not the end of the month. Also Cisco has a 72 hour waiting period between any exam. I took the exam (again) today as that meant I could make one last ditch effort on Friday since mine would have expired on Sunday and there are no test centres here open on the weekend.
