Cisco 4224 versus 26/3600 [7:37051]
Does anyone have experience with the 4224 and/or 2651/3640 platform in a branch setting? I am looking at both platforms and considering VOIP, but mcast and QoS are required. I know that LLQ is not available yet on the 4224. Thanks for the input. = Robert Padjen __ Do You Yahoo!? Yahoo!

Re: VLSM and CIDR [7:37031]
Hmm, ny take is this Cidr implies networks with non classful netmasks vlsm is dividing a netblock into uneven chunks, like say a /24 int a /25 and 2 /26s.

Re: VLSM and CIDR [7:37031]
what gets me is how Cisco says they support CIDR in their implementation of RIPv2, and yet CIDR routes are not advertised natively. You have to F*G redistribute CIDR routes into RIPv2 before they will be advertised. Exactly what good is that? Oh, and boo to CCO for the absolute lack of any information on this.

RE: VLSM and CIDR [7:37031]
Chuck, to my knowledge the command "ip summary-address" is used to summarize IP address pools for dial-up clients, not for actually summarizing subnets. Also, Cisco CCNA Certification Guide (ISBN 0-7357-0971-8), page 393 says: "EIGRP and OSPF are the only interior IP routing protocols to support route aggregation". So I am prone to conclude that the ability to do VLSM does not automatically means that you can do CIDR . My two cents ...

FW: A Review of Hello Computers workbook for CCIE [7:37041]
do they have this workbook for the R&s ccie -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Priscilla Oppenheimer Sent: Tuesday, February 05, 2002 1:55 PM To: [EMAIL PROTECTED] Subject: A Review of Hello Computers workbook for CCIE secu [7:34507] Hello Computers recently published their "Lab Workbook for Cisco CCIE Security Lab Exam Preparation." Keyur Shah from Hello Computers, Inc. asked me for feedback on the workbook. I decided to share my feedback with Group Study. The workbook is a great learning tool and a lot cheaper than buying equipment yourself. The lab rental service seems well run with good customer service. The workbook is available from Hello Computers or from CertificationZone. I did not receive compensation for this review. I have done work for CertificationZone in the past, but they did not know about this review. The workbook consists of sixteen labs that cover all the topics in the CCIE security lab test. The workbook costs $645 and includes 24 hours of remote lab rack access. It's worth the money. The labs are well-written and easy to follow, but challenging. The rack implements a complex network of 10 routers connected via Frame Relay, ISDN, Ethernet, and ATM; a Catalyst 5500 switch; and various security devices, such as PIX boxes, two Sun workstations with Solaris 8, and some NT servers that handle TACACS, TFTP, syslog, and so on. Hello Computers has been in the IT training business since 1996. They seem to be a robust and innovative company. Because they have had a few years in this business, they have had a chance to implement some new training technologies, such as distance learning and virtual labs. (With a WebEx player, you can actually attend an audio class remotely and see the configurations input by the instructor.) One of the best features of their service is the Live Person chat that you can open with tech support while doing a lab. I managed to gum up the Terminal Server (due to my ignorance not any fault of theirs! ;-) I started the chat and was immediately connected to someone who helped me. The CCIE Security workbook consists of four full-scale 100-point labs and twelve labs of 50 points each. The 100-point labs have instructions on all topics, whereas the shorter labs concentrate on a subset of topics. Each lab is divided into 5 sections: 1. Routing with EIGRP, RIP, OSPF, and BGP; switching with VLANs; and PIX fundamentals 2. Tasks aligned with the Managing Cisco Network Security (MCNS) class, such as avoiding DOS attacks, etc. 3. Advanced PIX 4. VPNs and IPSec 5. Intrusion Detection System Every lab has tips (hints) at the end. The workbook also comes with a CD that has initial configs such as IP addresses and other basic configurations that you might not want to waste your time on. The CD also includes solutions for each lab. The solutions have some minor mistakes, but Hello Computers plans to publish updates on their Web site. The lab network diagrams are in color and are laminated. Since I used them a lot, I was grateful for their sturdiness. Also the lamination means that you can write note on the diagrams with a dry erase marker. The first step in every lab tells you to redraw the network diagram. This is good advice. The network design is quite complex and more convoluted than typical real-world networks. Group Study readers have heard about my concerns regarding the OSPF virtual link and discontiguous Area 1. ;-) But I guess those are things you need to know for CCIE. I was confused at first that all "sites" in the internetwork are connected to the same Catalyst switch. Obviously this wouldn't be the case in the real world and perhaps that should be pointed out to people new to CCIE labs. Also, perhaps the labs would be more real-world if they specified why the customer wants all these complex features enabled. But this sort of additional information wouldn't help one prepare for CCIE, so I don't consider the lack of it a major fault. It's just my design bias showing. In summary, this is a classy product and service. I recommend it.

Re: VLSM and CIDR [7:37031]
kinda in answer to your private message: http://www.cisco.com/univercd/cc/td/doc/product/software/ios121/121cgcr/ip_c /ipcprt2/1cdrip.htm watch the wrap according to this, Cisco's implementation of Ripv2 does indeed support CIDR On the other hand, getting this to work appears to be problematic. A check of Doyle shows no CIDR example for Ripv2 A look though Large Scale IP Network Solutions yields this interesting sentence: "RIPV2 is able to support classless interdomain routes. It can propagate a classless route through redistribution" I can't get a damn CIDR route to show up in the RIPv2 table no matter how many hokey pokies I do. At this point I'm going to assume you have tried RipV2 and have had the same frustration I just had - seeing no CIDR routes. This calls for a bit more research.

3640 Modem over BRI / Cisco Secure ACS with MAC client [7:37040]
I have a scenario where I need to implement modem over BRI. Basically I have 2 ISDN BRI lines and 3640 with 4-port BRI U interface module and digital modem module. I need to have Verizon who is providing ISDN lines. I know they have to set their ISDN switch to provision incoming call from PSTN since the users will be using regular analog modem from their laptops. What information do I need to give them? The person I talked kept asking me about capability package/solution 94. I had no idea what they were. Could someone tell me exactly what information they are looking for? They mentioned something like NS1 or J6. I also need to find out if Cisco Secure ACS will support MAC client for :Radius authentication. The radius server will use the NT server user account info for authentication for their domain, how do I make it work so the MAC client can access resource in thier NT domain? Thanks a bunch.

So take this for what little it is worth: If you are talking about a public FR network, beware the jitter. When ATM was emerging, I seem to recall a lot of folks touting the fact that it would solve some of the variable delay implications of - you guessed it - frame relay for applications such as video. And of course, video is sensitive to that. But I have no tangible experience with the matter.

Re: VLSM and CIDR [7:37031]
I think you're trying to outsmart yourself. Can't be done!!! ;-> I showed you in my private reply the result of the EIGRP test I set up. The answer was "no problem" I also know from long lab rat experience that it is not a problem with OSPF. I have not tried with either IS-IS or Ripv2, but again, why not? there may be issues with older IOS code. Some vendor older models may not support it. But I have no reason based on my experience, to believe that it is an issue with current IOS code.

RE: VLSM and CIDR [7:37031]
The statement that provoked my question is from RFC 1721. They say "Subnet masks are also necessary for implementation of "classless" addressing, as the CIDR work proposes" thus the question "if a routing protocol supports subnet mask does that automatically mean that it can do CIDR? ( I think the answer is no because CIDR means that you could have masks stilling bits from the newtork ID and the router may not like this I also think that historically subnetting and Variable Length subnet masking came before CIDR. But those are just speculations. I don't have examples / references to support my arguments and I would like to know if I am correct.)

Audio Training, was Re: Re: Sample Rate [7:36566]
I know that I like this sort of product and I wish I'd had more of this sort of thing available when I first started out in this field. For certain types of learners, hearing someone discuss the topic allows it to sink in better than reading alone. I'm definitely that type of learner. One problem I've seen with some audio-based training is the pricing. IMO, they are often priced too high. While audio training is quite nice to have, it's not necessarily as portable as books, for instance, although that is changing quickly.

Re: A Note From Your Friendly Moderator [7:36978]
The "forbidden words" are there mainly to stop spam, but also to stop some of the non-Cisco study messages that occasionally pop up. references to entertainment sites of various kinds ( you guys especially know what I mean ;-> ) certain types of language, even certain web sites are flagged. no biggie. for example, xxx gets flagged. any message referencing router xxx ends up in the queue. your friendly moderator reads the message and determines it is ok to post, and not a solicitation to participate in certain recreational activities, and all is well. BTW, messages of excessive length get flagged as well. There is one list member who subscribes to the digest, and who every time she goes on vacation, ends up trying to post an "out of office" message with a long digest attached. plonk another funny forbidden word is "teen" again - put in there to stop spam from a certain entertainment site. Every discussion about token ring speed gets flagged because "sixteen" shows up on the list. ""Steven A Ridder"" wrote in message news:[EMAIL PROTECTED].; > what are the forbidden words?

Applying "prefix-list" to "interface" (not BGP processor), is [7:37017]
I think the same message that I sent out yesterday to the list somehow got lost - never saw it showed up. So here it comes again. I was trying to see if it's possible to create an "access-list" that has sequence numbers associated with each entry in it. The goal here is to be able to insert a new entry to a specific position (for example, to the 3rd line, instead of to the bottom) so I don't have to take the whole access-list out, re-arrange the order of all entries, then insert it back to the router. This "access-list" will be used on Ethernet interfaces. Although I had never tried, somehow I have the impression that it's doable via "named access list", at first. After spending several hours on this issue, it seems to me that I was wrong. Couldn't find a way to add the sequence number to entries in "named access list". The closest thing I could find is "prefix-list". However, I couldn't seem to find out how to associate the "prefix-list" that I created with Ethernet interfaces on my routers (Cisco 4500 running IOS 12.0). Cannot find the command under the (config-if) mode to make the interface work with the "prefix-list". I checked the archives, the books I have, and Cisco website. The only time "prefix-list" is mentioned is when talking about BGP. Looks to me that "prefix-list" is specifically used with BGP for route filtering, not with router interfaces. Am I right about this conclusion? If that's true, is there any other way that could achieve my goal? Thanks for your help!

Re: Re: Sample Rate [7:36566]
Speaking of sample rates, I am playing with the idea of offering audio training using MP3 files. I have prepared such a training on WAN Troubleshooting. I'd love to get some feedback. This audio training will help people studying for the Support test especially. It's 40 minutes. This means the file is huge, so don't try this at home on a modem line. The file is available for download here: http://www.troubleshootingnetworks.com/audio.html Please send me some feedback. Would you find such a product line helpful? Would you pay for MP3 audio training files? Thanks.

Re: read and not write TOS [7:36946]
On the Cat 6k you can do IP Prec or DiffServ. Otherwise you have to map 802.1p to Prec or DiffServ. By summer a lot more models will be able to do this such as the 2900 and 4900, 4000, etc. Nortel already does this on their Business Policy Manager switch and it's pretty reasonably priced at $3000. FYI, IP TOS is the entire 1 byte field within an IP packet and contains the IP Prec Bits (3 most significant bits in that field) or DiffServ Bits (6 most significant bits). You set those, not ToS. I'm just nitpicking, but Pricilla would be proud. :) -- RFC 1149 Compliant "" wrote in message news:[EMAIL PROTECTED].; > I don't think you can set the ToS bits on a switch.

RE: Multicasting problem [7:36941]
Hi Tom, here is the explanation from the Cisco site: In multicast routing, the source is sending traffic to an arbitrary group of hosts that are represented by a multicast group address. The multicast router must determine which direction is upstream (towards the source) and which direction (or directions) is downstream. If there are multiple downstream paths the router will replicate the packet and forward it down the appropriate downstream paths—which is not necessarily all paths. The concept of forwarding multicast traffic away from the source, rather than to the receiver, is called Reverse Path Forwarding. RPF is a fundamental concept in multicast routing that enables routers to correctly forward multicast traffic down the distribution tree. RPF makes use of the existing unicast routing table to determine the upstream and downstream neighbors. A router will only forward a multicast packet if it is received on the upstream interface. This RPF check helps to guarantee that the distribution tree will be loop free.

Dear Cisco professionals, I have a big problem on my AS5300 which is terminating VoIP calls. It uses around 2 times send bandwidth in comparison with its receive bandwidth. In the show int eth 0 command I could see that the number of packets/sec on its output part is also about 2 times of input part. Is there anyone who faced with such a problem and know how can I recover this problem of mine? I would like to thank you for your kind attention and cooperation in this regard. I look forward to hearing from you kind friends. Sincerely, Bahram Sadjadi Biria.

BCSN [7:36985]
Hello Friends, I just scheduled the BCSN exam for Next Sunday. This is my second try at it. I really know a lot more then I did the first time around, and the first time around I only missed by a few questions. My question is, saying if I did pass this exam, when will the new exams be implemented? How much time do I have to take the other 3 exams before they change to the new format? I guess this is motivation for me to get the CCNP done quickly.

RE: CID advice needed [7:36955]
The cid book you have is good and no the book doesnt go beyond what you need. Try using a boson test written by bernad ( I dont remember what number it is, it will show who the author is in the begining of the demo) The detailed answers will give you reference to the book you have as well as where to go at cisco on line. Its a tough test be prepared to sweat.

Re: MPLS in CCIE [7:36682]
Uh, Are you sure? Take a look at the C/S lab requirements. Not the written requirements, but the lab requirements. Notice how the lab has practically nothing to do with the written(s). Part of the great confusion over the C/S program is the fact that it has 8 possible writtens (each one concentrating on one particular provider technology - like you mentioned: optical, dial, DSL, etc.). But then the lab has nothing to do with any of those technologies, and concentrates on those niche provider applications that I mentioned before. No matter whether you passed the written for optical, or the written for dial, or whatever, you still end up taking the same C/S lab as everybody else, which by the way has nothing to do with optical, or dial, or whatever you did. This stands as a far cry from, say, R/S or the Security CCIE program, where the written actually is tied fairly closely to the lab. Again, this further adds to the confusion and muddling of the program. By becoming a fully-fledged C/S CCIE, you have not demonstrated hands-on competence in the ONS series, or the Stratacom stuff, or the Cisco DSL stuff, or whatever. You have demonstrated only book knowledge. Like I said, if you don't believe this, take a look at the lab requirements carefully.

Re: Frame Relay lab scenario.... needing help. [7:36929]
Mark,
I think you don't use "frame map", you need to use
"frame-relay route xxx " on the switch. Also use
"frame-relay switching" in global configuration mode.

RE: Serial Interfaces disappear on a Cisco 2500 [7:36968]
If I'm reading this correctly, I am quite frankly stunned beyond beleif that that box is running at all. It appears that you have the Cisco IGS software loaded on a 2503. I beleive the IGS never had a option for 2 serials. There were only 3 model; 2E, 1E 1S, and Token Ring. So how you are getting what you are getting is beyond me. I recommend getting a good version of the IOS for the 2503 (this will probably involve purchasing SmartNet for this box) and reflash it.

Re: Problem of upgrading IOS for a router at remote site [7:36971]
Tony - You need to burn a CD-ROM with Cisco's tftp software on it and the IOS image you want installed. Send it to the remote location and have them setup the TFTP server and copy the IOS image onto one of the computers. Then you can telnet back into your 2620 and copy the flash from the remote workstation onto the router. You might want to overnight the CD to them ASAP. wrote in message news:[EMAIL PROTECTED].; > Hi group, > > I run into a big problem when upgradeing IOS for a router at remote site.

RE: BGP and Select path for a AS [7:36947]
This isn't a complete solution though, as you've done nothing to influence the traffic that is coming back into your network. In addition to the steps mentioned below, you will want to AS-Path prepend your the connection that you want to use as the backup. This will get 99% of the traffic to come back to you via the preferred link. The only reason it isn't a 100% guarantee is because some AS's may implement a policy that overrides your as-path prepend. I can help you set this up if you need assistance.

Re: Can i choose which firewall to use for internet? [7:36920]
based on your private message - you left out the fact that these are remote sites connecting to a central site, and you want each of the remote sites to use a different firewall the answer is policy routing on the central site router. I sent you a rough config idea, but it will have to be refined a bit using access lists so that internet traffic is distinguished from non internet traffic. but policy routing is the way to go, give a central site and several remote sites.

Re: Problem of upgrading IOS for a router at remote site [7:36966]
Never ??? Thats a hard call when unless your company has lots of free frequent flyer miles. There are ways to make sure you don't blow it. 1. Test your new image on a router with simular hardware configuration if possible. That way you don't boot it on an incompatable OS. 2. If you have the room in flash, keep the old image. 3." line vty 0 4" "no exec-timeout" This will keep you telnet session alive. Or, hit the space bar once in while to keep it from timing out I have upgraded remotely many times and never blown it. However, it isn't without risk. I always cross my fingers !!

Re: Problem of upgrading IOS for a router at remote site [7:36965]
Would you be able to send them a console cable, and talk a non-technical end user at the remote site through: 1. setting up pcanywhere or a similar package on a pc at the remote site so that you can set IT up as your tftp server 2. connecting the console cable to the 2620 and the pc running the remote control software.

But the router will close the telnet session after certain period of idle time, and surprisingly close the tftp session as well. It ends up that the router's flash memory has no valid IOS stored! There is no technical staff on that remote site, and it is more than a thousand KMs away so I couldn't use a console cable to directly attach to it. I repeated the above several times, watched those "!" going on until the telnet session closed, and have to pray that there is no power surge happened to that router before I find a solution! Anyone faced this problem before? Please help! Tony -- __ Your favorite stores, helpful shopping tools and great gift ideas.

CID advice needed [7:36955]
Hi All, Sorry if this question has been asked before but a brief look in the archives yielded no results. I'm studying for the CCDP and have only the CID exam left to take. I'm using the Cisco press book "Cisco Internetwork design" by Matthew Birkner. I'm about half way through it and I can't help feeling that the contents are at too high a level to be of help when sitting the exam.. Can anyone advise if my suspicion is correct and if so what would I be better off studying?
