Re: Off Topic - inauspicious beginning [7:45592]
haven't looked lately. In general, you can take the lab six months from now, or you can take it tomorrow. I.e. there are always last minute cancellations, so you can get in with very short notice. Otherwise, the wait list is about 4 months I picked December for a particular reason, or actually a couple of particular reasons. I postponed from my scheduled June date. Best wishes.

How long is the wait list? Not worth dragging this one out much longer. the router model is 36xx, which alone should be a big clue. the router is situated so I can easily get to the serial ports, leaving the aux and con ports up against the wall, so I have to reach behind, feel around with my fingers, find the port, and fumble around some more to plug in. all other models I have worked with have the con and aux port on the same side of the box as the data ports.

So I have a customer network that I need to clean up a few things on. I set up a model in my own lab, cable everything up to emulate the customer's situation, and begin.

I try the usual suspects, and come up empty. no problem. I'll just do a quick password recovery. I do a search on CCO, quickly locate the procedure, and begin... power off. power on. control break. no luck - the router just boots as normal. hhm I've done recoveries before. no biggie. why am I having the problem?

I have been trying this via my term server. I go directly into the router, replacing the term server cable with a direct connection. still no luck. alt b with Tera term, control break with hyper term. the router still loads as normal.

Re: why I can't configure scheduler allocate? [7:34579]
I can only parrot what the command references on CCO provide. The master
reference for both 12.1 and 12.2 specifically state that the command in
question is for 72xx and 75xx routers. However, elsewhere I was able to find
reference to use of the command on 17xx routers with ADSL WICs.
My bunch of 25xx's running enterprise code do not have the command
available..
It should not be a surprise to anyone who has studied Cisco for a while
that there are discrepancies between what the published references say and
what really can be done on routers. My most recent favorite is the show ip
protocol-discovery command which seems to appear on only one particular IOS
image for the 3620 router.
I would say at this point that your question is more properly directed to
Cisco.

Could you define what you meant buy if an iBGP peer learns that another iBGP peer already has a better route to a specific prefix, it will issue a withdrawl to that peer for the prefix(es).

My router that connects to AS 701 has also learned roughly 104k prefixes via eBGP... Via iBGP, the AS1 connected router tells my other router of the 104k prefixes that it has learned... At the same time, my AS701 connected router is transmitting the 104k prefixes it has learned to the AS1 connected router... Once each of my routers has finished their mutual exchange of routes, the AS701 connected router sees that for all but approximately 700 prefixes, the AS1 connected router has an equally good path, and via the iBGP connection, he issues withdraws for 103.3k of the routes that he had previously announced to my other router... At this point, each of the routers has a full table learned via eBGP, and 'show ip route' yields about 4 gazillion pages of output... A 'show ip bgp' also yields a ton of output, but the AS701 connected router shows two entries for each prefix (One learned via the external peer, and one learned via the internal peer), but the AS1 connected router has a single entry per prefix. If both of those routers are receiving full routes, and without any other configuration, how would the routes learned from one provider be any better than the other? With no additional configuration, customer routes (those that originate in a directly connected external AS, or are a single hop away, if single homed) would be fewer AS hops away...

my quick read is the concern that Unity and Call Manager run on the Windows

convergence boxes.
so yes, there is reason to be concerned.

Re: OSPF DR problem [7:34379]
Cil, I drew this one out a little differently just to put a fresh perspective on it. Without seeing the requirements of the particular practice lab you are using, it's hard to say why you were seeing or not seeing what you did. area 0 -- || R1R2 || frame relay area 1 ISDN area 1 || R9R8 || -- - area 2 The discontiguous area 1's are irrelevant unless there is overlapping addressing. The area 2 is placed the way it is in order to force the creation of a virtual link - common in practice labs and study materials, as all us CCIE candidates know full well ;- I am inferring from other comments in other posts that you needed to use the IP ospf priority command on the R2 ethernet because the requirement is that R1 is the DR in area 0. So, given what I see ( not knowing the particulars of your addressing and various other things, there is no good reason why R9 and R8 should not see the ethernet network that is area 0. Along the trail of broken things, I have sometimes run across bizarre issues which are solved only by reloading routers. My humble pod of 2501's running enterprise 12.1.11 code sometimes have bizarre problems. I have a theory that these bloatware images just barely operate within the confined spaces of 16 megs of DRAM and sometimes you have to clear it out. I have had bizarre things happen when configuring and unconfiguring various routing protocols and features. Sometimes, admittedly, mistakes happen when you are tired, and you can't see straight to correct errors you have made. But other times, reloads have made magic happen. I am at the point where I am thinking about backloading to an IOS build that takes less space, just to see if the occasional weirdness disappears. Again, based upon what I have seen throughout this thread, and given that your areas and other configurations are correct, I see no reason why the area 0 network should not be visible from R9 and R8. Chuck PS as has been discussed here and elsewhere many a time, good practice and good design have little in common with the CCIE Lab ;- PPS which practice lab are you looking at?

The virtual link was from R1 over to another router across the Frame Relay cloud. R1 is an ABR connecting Area 0 and Area 1. Area 0 is the Ethernet LAN. Area 1 is the Frame Relay cloud. For some unknown reason, there's an Area 2 also on the other side of Area 1. Does that ring a bell regarding any gotchas? Priscilla, There must be at least three areas involved in a virtual link. So I am intrigued by the phantom area 2. What area were you expecting to see on the other side of area 1? In your case, it seems as if the ABRs are directly connected. That is to say, the transit area is in essence a p-t-p connection. That isn't always necessarily the case so I don't think OSPF makes any kind of distinction. As I understand it, the virtual connection/tunnel is treated like an unnumbered one. So the network statements have to be in place for the transit area in both routers, area 0 in the backbone ABR, and the discontiguous area in the discontiguous ABR. So that is the basis for my interest in your phantom area 2. Of course, this doesn't seem to be in any way related to why you wouldn't be able to see the area 0 network across the ISDN connection. The interesting parallel is that virtual links and demand circuits are both treated the same. That is, the DNA bit is set for routes learned via either one. So is there anything in your setup not consistent with having DNA show up in the topo table? I can't imagine what but I have never tried anything like your

Re: OSPF DR problem [7:34379]
Two comments: 1) so long as there is an area 0, and all other areas connect to it, those other areas can all be area 1 ( or any other arbitrary number ) and there will be no reachability problems. This assumes no overlapping subnets. Other than making summarization a bear, there is nothing wrong with doing it this way. Bad practice and bad design, but not bad behaviour. 2) I'm interested in your rationale as to why a discontiguous area 1 would in and of itself cause a problem with routers in either of the discontiguous areas such that they cannot see area 0 routes. I can't think of one myself, which may or may not mean anything. Chuck Dusty Harper wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]... Maybe Discontiguous is the wrong word for it.The problem I see with this design is that there is basically 2 Area 1s. The point -to- point connections would be fine, however in order for the Areas to function properly they need to know of each other ( all of Area 1 as a whole needs to know of the other) This is done via LSA Types 1 and 2. I know the reasoning for the Area 2, however I still stand behind the notion that if you were to change the Frame-Relay Area to 3 your problem would be solved You might also get around this by changing from point to point to a non-broadcast environment and specify all of your neighbors Router IDs' : R1 (S0) R2(BRI0) R9(S0) and R8(BRI0) on each of the routers. -Original Message- From: Chuck Larrieu [mailto:[EMAIL PROTECTED]] Sent: Mon 2/4/2002 8:33 PM To: [EMAIL PROTECTED] Cc: Subject: Re: OSPF DR problem [7:34379] Cil, I drew this one out a little differently just to put a fresh perspective on it.

Cisco hasn't put major development muscle into the Stratacom line ever since the last major hardware refresh, the MGX8850, which came out more than 2.5 years ago.

I have heard some reasons why the CCIE track was cancelled was due to the fact that even people working on the switches could not gain access to the equipment, just for the lab purpose. But why cancel the NP/NA track. Probably, people that needed these boxes already have it. They already either have more than they need for future expansion or since big chunk of the customers were telcos, they are in bad financial shape or going out of business. Lucky for me, I only got the the CCNA-Wan part before they cancelled the program. I have other buddies that actually work on our backbone and they went through to NP. And then it was cancelled. Now they are all studying routers. - Paul Message Posted at: http://www.groupstudy.com/form/read.php?f=7i=34299t=34035 -- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]

IPX over IPSec Tunnel - mystery solved?!?!? [7:34231]
It's been a while, so let me restate the problem. R1--internet---R2--ethernet---R3---frame_relayre st of network |-IPsec_tunnel---| IPX encapsulated IPX RIP | |-IPX EIGRP---| hope this makes sense. all routers are seeing all servers and all routes. However, the IPX client workstation cannot see or log on to a server located somewhere in the EIGRP domain. I had been blowing off the customer, telling him it was a workstation / NIC problem. He finally got ticked at me, and I finally went on site to see what I can see. Note - I am in sales, not implementation. The implementation people closed the project once they saw all IPX routes on the R1 router. So I arrive on site, and find that IPX pinging is not properly working. R1 can IPX ping to R2, but not to R3, or anywhere else in the IPX EIGRP domain and visa versa. HHHmmm.. IPX routes are showing up everywhere. IPX servers show up everywhere. debug IPX routing shows routing exchanges taking place. But IPX ping fails from the IPX RIP domain into the IPX EIGRP domain and back. Got a clue? I didn't, so I opened a TAC case. Let me add that R1 and R2 are 827 routers with IP/IPX/IPSec IOS images. R3 and the rest of the network are 1720 routers with desktop images. Cisco's answer, given in an offhand manner after reviewing my configs, blew me away. I can come up with no rationale as to why their solution worked. But here it is: add the statement no ipx route-cache to the tunnel interfaces of the 827's. One of my pals in implementation telneted in, did so, and told me that IPX ping was now working fine from every place to every other place in the network. Cisco TAC told me that it sounded like a problem with fast cache Huh? What further puzzles me is that I cannot duplicate the issue here in my own lab. IPX pinging works just fine from the RIP domain to the EIGRP domain across the IPsec tunnel. 25xx routers all, with more or less the same IOS versions.

Off Topic - CCIE LAB and NDA [7:34244]
before I shut down for the evening, a few random thoughts on the CCIE Lab and NDA. Inspired by several posts here of late from persons asking about topology, IOS versions, or speaking of rumors about equipment changes. 1) It is unclear what really constitutes NDA. Caslow? The ECP1 class? NLI's practice labs? Caslow's new prep class? Cisco's own ASET lab? All of these could be considered violations of NDA in many ways, from topic content to lab topology. Cisco's own ASET program used real but retired CCIE labs. 2) what is it Cisco really considers CCIE level skill? In the past, things like DecNet, Apollo, and Vines were core topics. Cisco has recently dropped those, plus ATM LANE, presumably in response to market conditions. Which leads one to ask - why token ring? The only real world token ring project I have been involved with the past couple of years is ripping them out and replacing them with ethernet. The apologia that there are still some major token ring networks around is a bit lame. There are still some major DecNet networks around, I'm sure. Until very recently ( and maybe they still are ), a major utility company out this way was still running Vines. As was the U.S Navy. 3) Is the CCIE a forward looking certification or not? Based on what I am seeing in the marketplace, the advanced skill levels that one needs to meet demand center around VPN, VoIP, wireless, security, and the underlying infrastructure required to support these technologies. that means lots of QoS, switching, L2-L3 interaction, ATM, giga-whatever, etc. I would purely love to see discussed good focused discussion on core competencies, core issues. But there is that awful specter of NDA that hangs over all of our heads. In a very strange way, NDA is kinda like Santa Claus and the Easter Bunny. We all know what's in the Lab. We all know what study materials are designed to model the Lab. But we don't dare speak the truth in front of the children ( those who haven't been yet ) for fear that some higher authority will trou nce on us if we do. I'm not sure if there is a real point to this message. Maybe what I want to say to all of those who keep asking about Lab equipment, Lab topology, Lab IOS versions, and the like, is that understanding of the core topics is the most important thing. If you have them down cold, the equipment and the topology will not matter. I'd like to comment on the rumor about changes in the equipment, but that damn NDA.

Re: frame relay question [7:34090]
Some telcos have some basic oversubscription requirements, designed more so that they can sell you more bandwidth than as a real practical requirement. Here in California, for example, the local telco permits no more than a 2 for 1 oversubscription. So if you have 20 spokes, each at 256K CIR, then you MUST have a minimum 2.56 megabit CIR at your center ( fractional DS3 or ATM ), for example.

each remote has two DLCI's - one to the first T3, one to the second. you use load sharing to balance traffic across the links.

Re: How prevalent is ISL in the real world? [7:33758]
It might be an issue of installed base, or lack thereof. I believe recent CatOS releases have corrected this, but for a long while, the Cat 400x series did ISL on trunks, while doing 802.1q on ports. Older boxes, of course, may only do ISL. In these days of tight budgets it can be difficult to convince customers to upgrade absolutely, everyone should upgrade to the open standard. absolutely, everyone should migrate from token ring to ethernet. absolutely, everyone should eliminate native IPX, NetBEUI, and AppleTalk from their networks. ;- Chuck Peter van Oene wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]...

Re: Slightly OT: 2924XL and Blue Screen of Death [7:32536]
thanks for taking the time to read through this, Cil. The problem continues to be a source of frustration for my client and for me. some comments / responses below: Priscilla Oppenheimer wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]... What version of NetWare are the clients using? Some of this may only apply to older versions. CL: the server is a 4.x box, the PC clients use the Novell Client32. Encapsulation issues are definitely a good place to start. You say that the router is using sap (802.2) but the client is using Windows 95, which probably did not default to 802.2. It probably defaulted to novell-ether. CL: I have worked with the client to try to determine this. I will revisit the issue. This is one of the things that I am not confident about. Where is the login server? Local or remote? Who answers the client's Get Nearest Server (GNS) request? Could it be the router? Could the router be telling the client about some server that can't actually provide login services? CL: All client PC's in the network log on to a central server. This is the first location where there is a problem. I dislike introducing wildcards into the discussion, but this is also the only location where there is an 827 router and a VPN involved. I am looking away from the router if only because the router is seeing all network devices - central server and print servers. So far as I can tell, the router in question is configured no differently than any other router in the WAN. CL: There is no internal network number configurered on any router in the network. CL: this would be a great place for sniffer capability, to really decode what is hapening. unfortunately, that is not an option. Routers have also been known to answer the GNS with the address of a server that the client can't actually reach, due to IPX access lists on the router. CL: no ipx access-lists on any router anywhere in the LAN CL: other folks have offered that ther might be a type-20 propogation issue. I re-read the Cisco documentation on this, and also checked back to my reference configurations from the IPX network I used to manage at the brokerage firm. I don't see type-20 as an issue, really. Perhaps I am misunderstanding, but type-20 is relevant only when using Micorsoft netowrking over IPX. None of my routers at the brokerage firm ever had type-20 propogation enabled. It was a strictly Novell / IPX network, and there were never any reachability issues. Check network numbers, both internal numbers (on the servers) and actual numbers on WANs and LANs. Make sure there are no duplicates. The symptoms sound mildly similar to a situation I ran into where the internal network number on a server was the same as a number used on the new WAN. CL: good idea, and one that normally would not occur to me. A colleague of mine also sugessted sending a print job to the local office printer from some other office, the theory being that if the WAN print job went through, we could eliminate the WAN as a problem. I assume you have checked this Cisco document on troubleshooting NetWare: http://www.cisco.com/univercd/cc/td/doc/cisintwk/itg_v1/tr1908.htm Good luck. Let us know what you discover! Thanks. Priscilla At 01:32 AM 1/23/02, Chuck Larrieu wrote: I'm resurrecting this one because I have a client. In fact, I was thinking about posing this as a Friday Folly of sorts. The situation is this: We install a VPN from one client location to another. We have done frame relay for this client, but frame was way too expensive for the particular new office location, and VPN is so generic these days... Customer is an IPX shop. 827 routers at both ends of the internet connection. GRE tunnel for the IPX. Al routers see all IPX devices on the network. However, the new workstation not only refuses to see the login server, but most of the time plain old crashes / locks up when booting. Remove the router from the hub, and the PC comes up just fine. During this period, the PC can also print to an IPX printer connected to the local hub. My employer's policy is that we have no responsibility for anything beyond the router, but I happen to like this client, and I happen to have a sense of responsibility in terms of recommending workable solutions to clients. So I continue to help. Suffice it to say that the client is clueless in anything beyond simple PC and server configuration. No troubleshooting skills. No sniffers, no advanced education in networking. So it can be painful trying to troubleshoot by telephone. So now I have the mystery of the week in front of me. The ethernet encapsulation is SAP ( Novell 802.2 ) The PC client is Windoze 95. Client tells me he has ghosted a Windows 98 image to the PC and experienced the same problem. Client also tells me he is seeing 802.2 and 802.3 frames on the local LAN, but I believe what he is seeing is a printout from the print server
Re: Redistribution into RIP [7:33138]
configure a /24 or shorter on the interface receiving the updates... ;- seriously, RIP will accept routes over a particular interface 1) by assuming that the incoming routes have the same mask as is used on that interface OR 2) at the classfull boundary. therefore, if the interface mask is a /24, then all routes from the same classfull network will be assumed to have that same /24 mask. Other networks will be assumed to be classfull. Example: interface = 10.1.1.1/24 then 10.121.121.0 will be assumed to be a /24, 10.1.2.0 will be assumed to be a /24, but 11.115.244.0 will be assumed to be a /8 hope that helps.

Re: Catalyst 6000 in CCIE Lab [7:32918]
It is possible that there are a couple of test racks with newer equipment. It may be that a couple of folks have been offered the opportunity to beta test a CCIE lab with a 6K switch in the pod.

I say this with confidence because the recommendations are very close to what I developed independently, using Cisco documentation and the 3920 simulator which I believe NLI is now selling. Confidence because not too long ago I was someplace where this was important, and everything worked the way it was supposed to on the 3920, at least. superior IMHO to the very good explanation found in the Kennedy Clark book. Chap 3 WAN HDLC - OK Chap 4 WAN PPP - not too bad. concentrates on ISDN / dial. The section on PPP multilink is incredibly poor, to the point of being useless. this surprised me, as there is so much detail elsewhere. Chap 5 - frame relay. another decent chapter. contains a HUGE error. states that frame relay split horizon is on by default, and that you have to disable it manually. not true, and the source of woe to many who find themselves frustrated with certain sections of various practice labs. on a frame relay interface, split horizon is DISabled by default. several CCIEs otta be ashamed of themselves for letting that one through! ;- The several lab exercises at the ends of each chapter cover the fundamentals pretty well. They are not necessarily CCIE level labs, but they are certainly worth looking at.

In both places in chapter 5 where I found him referring to ip split horizon, it seems that he's referring to it in reference to frame-relay multipoint subinterfaces. So if that's the case, he is correct to say it needs to be disabled.

Re: Slightly OT: 2924XL and Blue Screen of Death [7:32536]
have you tried this particular machine in the other switches? sometimes a bad windows installation on a pc will blue screen no matter what. John Neiberger wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]... We're having an interesting issue that just appeared recently. We have some Dell PCs running Netware 6 and new client software. We're not sure why, but if one of these machines is connected to a 2924XL switch, it regularly experiences a blue screen of death either at login or within 5 minutes of login. We have identical machines that operate fine if they're connected to our Bay switches or Cisco 1900 switches. Have any of you seen anything like this?? That makes no sense to me. The only difference I've been able to determine is that Spanning Tree is turned off on those particular Bay switches and 1900 switches, yet it is turned on on the 2924XL switches. So, perhaps these PCs are reacting badly to STP BPDU. Any thoughts? Our LAN people are doing some testing with different NIC software and Novell client software and I'll post back to the list if we determine the actual cause of the issue. But can you think of why it would only happen if they're connect to a 2924?

[7:32345] Hi, all; I recently started considering why I might want to have a 32-bit mask for my loopbacks as opposed to some other scheme - for instance using the regularly documented 24-bit mask on a loopback. I am speaking of course, of: Interface Loopback0 IP Address 10.0.0.1 255.255.255.0 versus approaching this matter in this fashion: Interface Loopback0 IP Address 10.0.0.1 255.255.255.255 So, my questions are: 1) Has any one here seen a detailed discussion of this matter? Can you provide me a link to it? 2) Based on what a friend of mine feels, his view is that there is never any benefit to having a 24-bit, or 28, or 29-bit mask on a loopback. In his view, loopbacks will always need to be, very logically, used with 32-bit masks. Can anyone please shed some light on this matter? Thank you.

It may also be that copy editors think that because it is tech, that what they see, although it does not make sense grammatically, does make sense to other techies. For a tech review I am currently working on, I had to specifically call the editor and tell him that the chapters were very poorly written, had lots of poor sentence construction, not to mention bad grammar, and that he should specifically be aware that the text made no sense no matter who was reading it. Hmmm... come to think of it, I haven't heard from those people lately. I wonder if they fired me? ;- I suspect that in this mad rush to get tech books out the door, many of the publishing houses are operating under the assumption that whatever a tech writer writes is correct.

Benjamin Kessler wrote: I have a couple of nit-picky complaints about the book (as I do about almost every book I read). There are some typo's as a previous poster indicated. One of my biggest pet peeves is the use of the term continuous when the author (probably) means contiguous - one sees this most often when discussing OSPF. That says that the author didn't look at the copy-edited material. New authors assume that publisher's copy editors have a clue. They don't. They apply rules for fixing words and sentences without any idea what they are doing. This means that you will probably find other minor mistakes in the book too. Don't blame the author, although the author should have been more careful during the final phases of the book project. Cisco Press copy editors once changed every case of Mbps to MByte in a book! In my book, in the index, they changed long fat network (LFN) to long file names. See RFC 1323 for the true meaning of elephant (LFN). Thanks for your thorough review of the book. Priscilla Note, this book isn't unique in this mis-use of the term; there are many CCO documents that also make this error. I'm assuming that this is the product of a spell-checker that didn't know the term contiguous, suggested continuous and someone hit replace all. Before the flame-war starts, I know that these two words have *similar* meanings but in this case I - my personal opinion - think that contiguous is 'more right' - besides, it's the term used in the RFC. Since I'm picking nits; the author indicates that the OSPF process ID on a router should be thought of as an Autonomous System ID. This number should be the same on all routers within the autonomous system. Per CCO, this is a locally significant setting used only to distinguish between multiple OSPF routing process on a particular router. If we were to apply the RFC2119 definition of should to this statement one might think that certain problems may occur if this practice wasn't followed. I don't believe this to be the case but I'm sure someone on the list will correct me if I'm wrong. There's nothing wrong with using the same process ID on all of your OSPF routers; I would guess that networks are configured that way more often than not; but isn't a requirement. Given that the lab exam is all about splitting hairs to the most minute detail and knowing the various protocols in depth, it probably should have been noted (as in other texts) that two adjacent routers can have different process IDs configured. There are some outright mistakes in the book - I just checked the CiscoPress site for an errata and didn't see one yet. Here one that I recall off the top of my head: EIGRP - (p.691) at the bottom of the page, the 'distance' command. - this is almost a direct copy/paste from the IGRP chapter; does not include the required information to change the admin distance of the EIGRP routing process (which requires both an internal and external distance); it only lists the syntax to change the distance of a specific neighbor's updates. I find it funny that the EIGRP chapter says For a specific example and more practice with the 'distance' command, see the IGRP chapter. When you look at the IGRP chapter, it uses the same sentence to point you to the RIP chapter. Anyone who has walked into an EIGRP network with multiple, unfiltered redistribution points into a RIP domain will know first-hand the importance of knowing how a router handles internal vs. external EIGRP routes. Additionally, I thought the section on PPP authentication could have used some more work on the one-way authentication options (both PAP and CHAP). Bottom-line, this seems to be a well written book; it gives you some good examples and labs to work on your own, etc. It won't replace any of the other must haves on the bookshelf (e.g. Doyle, Caslow, Thomas, etc.) and unfortunately, (as it seems with all of the books published these days) you have to play 'reporter' and verify the

I chose half.com because they claimed to have the book in stock at the time I was ordering. Other places stated no availability.

Just got my copy. Reading the About the Authors section alone is impressive. All those associated with the book are CCIE's. I look forward to discovering if there are any errors in the book. One would hope not, given the credentials of the writers and reviewers, one of whom was the Halifax Lab Proctor for several years. So far I have browsed all of the first chapter The Key Components for Modeling an Internetwork This chapter covers in good detail all those basic questions - the config register, configuring a router as a frame switch, password recovery, show and debug ( called the big show and the big d respectively, throughout the book. ) building a terminal server, and much much more. This alone tells me that this book might be a good investment for those just starting out, as well as those prepping for the CCIE Lab. Sure, all of this information is available elsewhere, but with this book, it is in one place, easily located, and clearly explained. There is even a section about configuring networking on windoze computers. Considering the number of raw beginners who are coming into the certification process, this is helpful. I'll have more comments after I have had a chance to look at the good stuff.

Re: CCIE Lab Waiting Period [7:32232]
Dare I release my currently scheduled date so I can look? ;- the rule of thumb is that you can book a date this week or in six months, but nothing in between. Also, I believe Cisco is opening up dates on a month by month basis. In other words, say for the month of February the schedule was based on the two day lab. So in late January Cisco opens up the 14 days formerly reserved for the second day of the two day lab. So for a very brief period of time there are a number of openings available in February.

Re: mentor back? [7:31964]
Is Mentor back in business? web site is not there. The news this morning is that a company called Element K has purchased the Vlab technology, and will be marketing the labs. Point to note - in terms of Mentor, Vlabs was an asset, people who bought services were creditors. The bankruptcy court will sell assets and use the proceeds to start to pay creditors. There is a specific legally defined hierarchy as to which creditors get paid in what order. Those who were owed rack time are last on that list. Sorry, but that's the way it is. Unless the Court specifically obligated Element K to honor the open rack time, they are under no legal obligation to do so. It is possible that as a gesture of good will, Element K might offer to make good on what Mentor owed. But depending on the terms of the acquisition, they may not be legally obligated to do so. Just as a note, there are plenty of lab scenarios available, free and otherwise, and more on the way. There are also plenty of places to rent rack time, with more on the way. To be truthful, I'm not so sure that the Vlab business model is as relevant as it was a couple of years ago. Time will tell.

Re: Ospf router id vs loop back [7:32022]
interesting question. came up in a customer meeting the other day as well. IMHO, this gets down to design preference. I am of the school of thought that there needs be some way of getting to any router in a network ( design permitting, cost permitting ), and that each router in a network needs some unique and easily identified pneumonic. So IMHO, one should use loopbacks, numbered according to some rational scheme, and that those routes should be advertised.IMHO This should be true, no matter what routing protocol you are using. However, others will ask whether in a 5000 router domain, you want 5000 extra routes in your tables. That is a valid counterargument. Using the RID command under the OSPF process, you can set up a rational identification scheme. The RID does not necessarily have to be related to interface numbering. But then you have the issue of correlating RIDs to the addresses one actually uses to get to the router in question, making it a bit more complicated to find things when you need to. JMHO.

why do you think you need to change? seriously? what would dynamic routing give you that you don't have now - in terms of stability and the like? it might seem an odd thing to say, but I believe that dynamic routing in small environments, and maybe even in some larger environments, is over rated, no matter whose routers or what routing protocols you use.

Again, my point is that there appears to be an issue with flagging the major network when all you have are subnets. I did not try advertising EIGRP summaries from R5 or R2. That might work too. Chuck s vermill wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]... Chuck, Many thanks for taking the time. Could you clarify that you are issuing the 'ip default-network x.x.x.x' command on one single router and all of the others are flagging it accordingly? Or are you issuing 'ip route 0.0.0.0 0.0.0.0 x.x.x.x' and then 'redistribute static'? By the way, you illustrate the classful/classless issue quite nicely. It is my understanding that, where the 'ip default-network' command works, you can issue it twice - once for the major network and once for the subnet. Murtaza, Thanks for the post. Both of the techniques in that text work quite nicely.

Re: GBIC ??? [7:31770]
there will probably be a ton of posts, but why not? I'm waiting for a download to complete. The 65xx series switches come of the shelf with a 32 gig backplane. If you anticipate needing a bigger backplane, you must purchase a switch fabric module ( SFM ) which then increases your backplane to 128 gig. Ah, but here's the deal. In order take advantage of this increased backplane, your line cards must be fabric enabled. Otherwise they will be able to use only the default 32 gig crossbar. Cisco is the only major vendor that does it this way that I can figure. Extreme and Foundry certainly don't. so get our your wallet and get ready to shell out if you require a bigger backplane on the 65xx product. kenairs wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]...

Sorry to bring this up again but apparently, for at least some of us, it needs to be. I chimed in the other day and offered a way to get EIGRP to distribute a default route. That basically amounted to simply defining a static to 0.0.0.0 and redistributing static into EIGRP (whoever corrected me by pointing out that the 'network 0.0.0.0' command isn't necessary, I thank you (it was in BSCN)). Wayne jumped in and explained some problems with EIGRP and the 'ip default-network' command. I thought it all sounded quite reasonable. So I tried this in the lab for several hours today (no get a life remarks please). I must be really dense, because nothing I try works quite the way (that I thought) it was described. It seems that the only way to sucessfully use the default-network is to configure it on every single router in the AS (I tried this with RIP just as a sanity check and it worked just fine). If that is the case, can a good argument be made in favor of this approach over redistributing static? Or summarizing to 0.0.0.0 0.0.0.0 on an interface? Both of those, at least, propogate throughout the AS after configuration on just one router.

This ended up being a four hour meeting, completely dominated by Customer IT Director and my employer's Mr. CCIE One of the high points? the customer had sent Mr. CCIE an L3 switch configuration the previous day. Mr. CCIE was to offer comment on the design. Mr. CCIE said from what I see here, I'll bet you have a routing loop. I'll bet that if you do a traceroute from that switch to this particular network it will go nowhere. The customer said you're on, telnetted into the switch, performed the trace, and sure enough, the * * * * * * appeared after three hops. You shoulda seen this guy's face! this was but a small part of a fascinating dialogue between the customer and Mr. CCIE.

Re: Doyle, RIP and Secondary Interfaces [7:31047]
we just went through something along these lines a couple of weeks ago. Try disabling split horizon on the interface in question and see if the problem is resolved. Chuck John Richards wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]... On pages 214- 215 of Routing TCP/IP by Doyle mention that when using secondary interfaces with RIP v1 the routing process sees secondary interfaces as separate data links. Thus in a routing table there will be equal-cost routes for the next hop addresses associated with both the primary and secondary addresses. I am not able to reproduce this, in my case the next hop address is always the one associated with the primary IP address. Was this behavior changed some how in later versions of IOS. I am using ver 12.2(1). Any help will be greatly appreciated.

Re: EIGRP 0.0.0.0 Route [7:25308]
I realize this thread is way old, but another possibility is to put the quad zero static route on the edge route, and use the default network command to propogate a default to the rest of the EIGRP domain. internet---internet_router-firewall-edge_router---eigrp_domain edge router configs ip route 0.0.0.0 0.0.0.0 interface to internet default-network address_of_inside_interface one more way to skin this cat. Chuck Michael Williams wrote in message news:[EMAIL PROTECTED]... Part of the reason I wanted to send a summary of 0.0.0.0 to the remote sites is so that they wouldn't learn a huge routing table full of entries thru EIGRP. i.e., I could send a summary route of 0.0.0.0/0 and that would effectively keep EIGRP from sending *all* of it's routes without having to mess with distribute lists, etc. If I rely on EIGRP to send that default route thru to the remote sites, it will indeed do that, but it will send it along with all the other routes.

Re: Passive Interface Help [7:30648]
I should also mention that in the ISP environment, this is particularly useful and particularly necessary. According to my reading, ISP's will habitually place all interfaces to the customer side as passive ( for the ISP IGP ) and will then specifically activate interfaces where route and routing protocol advertising should occur. All of the examples surrounding the passive-interface default command ( available in IOS 12.0 and higher ) that I have seen on CCO specifically reference ISP requirements. Essentially, why advertise internal routes and updates out every dial up and DSL connection? Why do your average Joe customers require this?

Re: CCIE prep [7:30730]
the idea of 24 hour rack rental can be attractive. especially for doing those full blown practice labs. OTOH, smaller increments make sense for a lot of reasons as well. Suppose I want to spend the last couple of weeks before the test doing certain specific things - voice, ATM, Cat configuration, for example? A couple of 8 hour sessions ( or less ) might be just the thing. Also, Brad, at present your racks require how much lead time to schedule? Last time I looked, it was weeks to months. One other place I looked it was days to a couple of weeks. I don't know at what point it makes it worth yours or any competitor's operation to add more racks, and I am not sure what the tolerance is for long lead times to get access.

They assigned odd-numbered subnets to different sites/areas, thinking the even ones would be for future use. My approach, incidentally, is to figure out the number of potential areas or sites, then divide by a power of 2, at least 4, to be summarization-friendly. There's no question that your approach takes fewer lines of code. Personally, I wouldn't use it except in a huge network where there was no other way to fit that many lines into NVRAM.
