Multicast Question [7:39732]
Guys, Need your help to clear some concept. Suppose we have 4 routers ,we want to configure 3 of them as a PIM SParse mode and one as a Dense mode.Can they communicate with each other??I meant can they transfer multicasting info to each other. or we must have to use PIM SPARSE DENSE mode on all routers?? Thkx for help.

RE: 3640 Digital Modem Problem [7:39709]
I looked over your config. It looks like everything's in order. I must admit I've not used the BRI as you are, only PRI, but concept is similar. I did find an URL: http://www.cisco.com/univercd/cc/td/doc/cisintwk/itg_v1/tr1917.htm (watch for wrap) I found something there saying: Digital (Integrated) Modem Call Pickup On an external modem, it is clear whether the call is getting answered, but internal modems require a manual call to the receiving number. Listen for the answer back tone (ABT). If no ABT is heard, check the configuration for two things: Make sure that the command isdn incoming-voice modem exists under any ISDN interfaces handling incoming modem connections. Under the line configuration for the modem's TTY, make sure that the command modem inout exists. It is also possible that an internal modem was not allocated by the Call Switching Module (CSM) to handle the incoming call. This problem can be caused by modem or resource pools being configured for too few incoming connections, or the access server my simply be out of modems. Check the availability of modems, and adjust the modem pool or resource pool manager settings appropriately. If a modem was allocated and the configuration shows modem inout, gather debugs and contact Cisco for assistance --- Note the last part saying "contact Cisco". Basically it seems you've done what this is recommending so a call to TAC may be in order HTH, Mike W.

Re: routing between vlans in 2900 throuh external 2610? [7:39725]
In some releases of the IOS you can't place the native VLAN on a subinterface. Remove the subinterface you have for VLAN1 and put the VLAN1 IP address on the major interface like this: interface Fastethernet0/0 ip address 10.1.1.1 255.255.255.0 interface Fastethernet0/0 encapsulation dot1q 2 (or is that encapsulation 2 dot1q ?) ip address 10.2.2.1 255.255.255.0 You get the idea.

Re: What is bandwidth domain? [7:38887]
But what if you bung a bridge in the 10.10.10.0/24 network somewhere? That will split your collision domain but not your broadcast domain. Or, more likely, what if instead of a hub, the hosts in 10.10.10.0/24 are connected by a switch (aka multi-port bridge ;-)? Then every host is in its own collision domain (well, each collision domain includes the host and the switch port), but they are still all in one broadcast domain. Just because the collision domain and the broadcast domain are the same in one specific case does not mean that they are the same thing in the general case.

Re: BGP Next-Hop [7:39704]
Hi Hunt, A little cut and past here. For those reading along, it page 150 of version 1. Router A (SJ) has only 1 physical connection which is to router B with an IGP next hop of 3.3.3.3. In this example, Halabi is describing the relationship between IGP and BGP next Hops. 2.2.2.0/24 is likely learned via the IGP and is reachable through via 3.3.3.3 which is the IGP next hop toward router C. The same goes for 1.1.1.0/24 which again is reachable via router C. Indeed, router A has only one path out of the network. In reality, the network looks like this: ABC---EBGP--D A,B, and C are fully meshed with IBGP. Hence, A will only ever have one IGP next hop since it has only one path toward other networks and must transit router B. Keep in mind that you are looking at the Routing Table, not the BGP table. These are quite different which is what Sam is trying to point out. What may be confusing you is that at first glance it looks like SF has a direct link to SJ (A to C) when in fact it doesn't, and the line in the diagram is really an arrow describing the logical IBGP connection. Hope that helps? Pete What I am confused it's the Routing Table of Router A, >Destination 192.212.1.0 /24Next-hop 2.2.2.2(Best Route inserted >from BGP table) - cool > >Destination 128.213.1.0 /24Next-hop: 1.1.1.1 (Best Route inserted >from BGP table) - cool > >Destination 3.3.3.0 /24Next-hop: Directly Connected via Serial >0 - cool > >Destination 2.2.2.0 /24 Next-hop: 3.3.3.3(why?? isn't this >directly connected via IBGP, shouldn't it be directly connected?) > >Destination 1.1.1.0 /24Next-hop: 3.3.3.3(why?? shouldn't >this have 2 routes, one via 3.3.3.3, and the other via 2.2.2.2?) > > >Also, I thought that in such a scenario, one would want to make sure that >every BGP Next-Hop can be reached via either IGP or static routes - However, >Halabi says it's only needed for IBGP Next-hop, is it correct? > >Thanks, >Hunt Message Posted at: http://www.groupstudy.com/form/read.php?f=7&i=39714&t=39704 -- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]

Re: framerelay between 2501 and 2611 [7:39617]
Sam, Yes that back-to-back config works, yet you will not gain the knowledge and skills that I think you are after. It's true, you do need a third router to be the frame cloud, but that doesn't buy you much either. The key is to make the frame switch, also a DTE Hub router. However, you must have at least 4 interfaces (like a 2520). This will allow you to connect a DCE/DTE cable between two of the ports, thus allowing the 2520 to also be a hub router. As you grow your lab, and add two more routers, the 2520 can still serve a frame switch for 4 routers, it just can't be a hub router anymore.

3640 Digital Modem Problem [7:39709]
Folks I need some assistance. Here is my problem. My customer has 3640 with 6-port mica digital modem and the 4-port BRI-U module installed. The IOS running is c3640-d-mz.120-3.T3 routing IP and appletalk. I am trying to establish a remote dialin access for mobile/remote clients dialing in using an analog modem. I am using modem over BRI feature. Verizon has confirmed the BRI lines are provisioned correctly to accept analog calls on ISDN lines and I believe they are correct. The calls come into the BRI modules, but never get forwarded to the digital modem module within the router. Every time I dial into the ISDN number assigned to the one of the BRI lines, I get one ring and fast busy after that. I am starting to think there is something wrong with my config. I have attached my config. Plesae let me know if anyone is familiar with this config. Thanks in advance. Firesox.

RE: Anybody use "Port Security" on Switch in [7:39457]
Yep, I've used it. There is considerable flexibility in setup. Some switches take up to several hundred MAC entries, learned or statically assigned. You can also set the thing up to simply alert through SNMP traps, and/or administratively shut down that port until you do a 'no shut', or otherwise enable the port. Typically, it's one MAC address per port for setup, but, sometimes, the ability to add one or more allowed address can be useful. Those pesky additional hubs out there can be secured by simply adding whatever 'allowed' addresses to the list on the port serving the hub/downstream switch. Syntax can be funny, and is in a couple of spots. GUI is quite intuitive, and dynamically acquire the MAC address(s). port security max-mac-count x ;x=number of macs port security action shutdown | trap ; traps, of course, must be set up ; meanwhile, elsewhere mac-address-table secure .. FastEthernet x/y vlan z Document this! Port security can be tough on workers in the field without switch knowledge and/or access. Best, G. VP OGC Chaos reigns within. Reflect, repent and reboot.

RE: Connecting Cisco to GateD [7:39671]
I too would like to do the sameso I'm all ears. :) This is what I found when I was looking into GateD before. Somebody correct me if I'm misinformed. If you want the functionality of BGP, OSPF, or any other routing protocols, you have to pay a fee (read quite expensive for most) for what seems like a Bells-n-Whistles version of GateD. The free version that comes with Linux doesn't have functionality aside from RIP for routing protocols. :( So, if there IS a way to get BGP, OSPF, IS-IS, and maybe even (E)IGRP functionality with GateD or any other Daemon package that will run on Solaris (x86 or Sparc) or Linux (any flavour), - FOR FREE of Course, then let us know!!

I only have a 2501 right now. I plan on buying a couple more. I have a few spare Dell's and extra nic's at work lying around. I would like to load Linux or FreeBSD on those and use GateD to make them routers. The point of this is to have extra networks to connect to the Cisco's and practice OSPF and BGP for routing. This way I can have more routes to dynamically discover and more to troubleshoot. Has anyone done this before? If so could you lead me to some documentation on GateD?

RE: Rack [7:38796]
Also... Just a little more to add to the Music Rack scenario: I have found that the RackMount Ears that come with the PIX 515 & Cisco 2600 do NOT line up with the alleged 19" scew points. The 2500s' ears are a perfect fit though. The problem with the other rack ears is that the screw slots are vertical, and therefore don't extend wide enough to hit both rack screw holes. The rack ears on the 2500 have horizontal screw slots, and therefore give variance from side to side of at least an eighth-of-an-inch. Doesn't that suck. :( Has anyone ever tried 2500 series rack ears/kits on a 2600?? If so, and they work, then the solution is at hand and as everyone else has mentioned, it depends on how much gear you plan to invest in to stick in the music rack. I was fortunate, and had my music rack given to me by a previous employer... I took it with the thought that even though I didn't have a use for it then, surely, I'd come up with one for it in the future:) That was 4 years ago, and in the last year, I started putting my Cisco gear in it. :) Only drawback is that it only has 30 inches vertically of usable space but who am I to complain... it got it for free! :) -Mark -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Barbee Jason Sent: Wednesday, March 27, 2002 9:03 AM To: [EMAIL PROTECTED] Subject: RE: Rack [7:38796] You have a couple options, the music racks already mentioned. I'll just add a little on that subject. Music racks. DJ equipment is also 19" wide, same as computer equipment. I looked at the Music racks. Some were at an angle, some were just odd looking. And there wasn't much cost savings. I found a vendor selling very cheap music racks on ebay for about $30. I considered them to be very limited in space, only a couple U of space. I wouldn't have been able to store all my current toys in a single music rack. I now have 5 2500's, 1 catalyst 5002, an isdn simulator box, a server, and 2 rack mountable hubs/MAUs. So your choice depends on how much equipment you can forsee yourself buying. Telecom Equipment Racks. They are 19" wide, and come in many sizes. A local vendor, Rexel Southern, had several 7' Chatsworth racks in stock. They bought in bulk, and I was able to get a great deal without paying shipping. My 7' black rack cost me about $115. I would look around your city, and see if you can find a telecom vendor if you want to look for a telecom rack. The 4' racks were about twice the cost, they could sell the 7' cheaper because more people bought them. -Jason www.CCIEwannabe.com - Affordable remote Cisco lab access Message Posted at: http://www.groupstudy.com/form/read.php?f=7&i=39652&t=38796 -- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]

RE: question on cisco lab [7:39683]
It seems that you are leaving the reverse telnet session "open" when you
exit a router console port via the Terminal Server.
Make a habit of using the command "disconnect" (short is "disc") everytime
you exit a reverse telnet session. Btw, do you use CTRL + SHIFT + 6 and X to
exit a reverse telnet session?
Or else, use the command "clear line xx" at least three times to reset the
connection, where xx is the line number assigned to the port you're trying
to access on the TS ("show line" will list the line numbers).

Im using a terminal server connected to my routers for my built cisco lab.
however
everytime that i change the ip address or modify the configuration i can do
a reverse telnet to the router? i need to plug in a laptop and modify the
con 0 line again
is there a reason for this. I thought that once you set this settings and

You would want to use 802.1q. But I think you would need to manually make sure that each switch had the appropriate VLANs on them (i.e. manually do the job of VTP). Mike W.

The history of TCP/IP is somewhat muddy, as you can imagine. At 02:04 PM 3/27/02, Steven A.

The Information Processing Techniques Office (IPTO) of ARPA awarded the contract to build the Interface Message Processors (IMP) for ARPANET to BBN in late 1968. IMPs were the early routers. BBN built the IMPs with the help (or hindrance if you believe some reports) of Honeywell. Honeywell developed and manufactured the hardware. BBN did the software. Descriptions of the "network layer" software that ran on these IMPs doesn't sound much like IP at all. It was connection-oriented, for one thing, and handled error correction. It was very East-Coast anal-retentive stuff. ;-) The software that evolved into TCP/IP was a West-Coast hippy-dippy geeky phenomenon. UCLA, SRI, UC Santa Barbara, USC, and University of Utah graduate students and researchers worked on it. Originally they had to make sure their software interoperated with the IMPs of the ARPANET. They developed a protocol called the Network Control Protocol (NCP) that worked on the end devices that communicated with the IMPs. It was a host-to-host protocol that could be considered a predecessor to TCP. NCP worked only with ARPANET. By 1973 or so, ARPANET wasn't the only game in town though. There was packet radio (which evolved into Ethernet), SATNET, and others. A more general-purpose protocol was needed. Vint Cerf who was with UCLA at the time and Bob Kahn, who had been at BBN but now worked for ARPA directly, worked on a new protocol called Transmission Control Protocol (TCP) that was general-purpose. They made the assumption that the underlying network was unreliable. The new protocol shifted the job of reliability from the network to the destination hosts. Originally TCP handled the routing of packets also. TCP had jobs that we would today assign to the network and transport layers. And finally, in 1978, we come to the birth of the Internet Protocol (IP). In 1978, the job of routing packets was broken away from TCP. TCP was given the task of breaking messages into packets, reassembling them at the other end, detecting errors, resending anything lost, and putting packets in the right order. IP was simply responsible for forwarding individual packets. The specifications for how this should work were written by Cerf at UCLA, and Postel and Cohen from the University of Southern California's Information Sciences Institute (ISI). In the early 1980s, the ARPANET got really congested and the National Science Foundation created its own network for the academic computer science community. It used TCP/IP and is sometimes considered the real forerunner of "the Internet," although it probably could never have happened without the work that went into the ARPANET. ARPANET converted to TCP/IP in 1983. It also divided into MILNET and ARPANET. It had connectivity with all the other networks by then. Later it got decommissioned. By 1989, it was gone, but its legacy lived on. May it RIP. ;-) Here's a recommendation for a terrific book about the history of the Internet: "Where Wizards Stay Up Late: The Origins of the Internet" by Katie Hafner and Matthew Lyon.

RE: TCP/IP and DOD [7:39657]
The DoD adopted TCP/IP as its native protocol for communications in 1983. DARPA lead the charge for a communications system that would be resilient to Global Thermal Nuclear attacks (therein allowing for continued, uninterrupted comm), and would allow for common connectivity of multi-vendor solutions. This of course did yield 'ARPA NET' which, by a decision of the DCA (Defense Communications Agency), in 1983 was split in two yielding a smaller version of 'ARPA NET' and 'MILNET'. The evolution of the modern internet can followed done the line from 'ARPA NET' and as we all know by virtue of adding new networks to the mix, 'ARPA NET' was de-regulated in 1991 ushering the age of the modern internet.

RE: Where do I start? [7:39553]
They say Abtronic doesn't work so I did get a look at these, someone at work had them. They are just some randomly thrown together questions and answers. And some stuff copy-n-pasted off the net (cramsession). Some have questions have explanations, some don't. If you think someone writing 100 questions and answers and pasting it in a word document is worth the 29$ or whatever they charge for that that junk then go for it. There is also a sheet with every command you can do on a cisco router, I don't see how that is usefull, unless you have a very good memory. And a Memorization list, with commonly known things on it, like what access list numbers go with what. And a cramsession which you can just go to www.cramsession.com and get it for free. Just look on the internet, there are thousands of sites with free questions, I think one of them is like cert21.com. Don't look at cramsession for questions, because their questions are from like 1970s. They need some new writers for there questions of the day. My suggestion is, unless your really bored with your money, buy some books with it, they are a much better value.

RE: Anybody use "Port Security" on Switch in [7:39457]
You can use port security to restrict any port down to as few as 1 MAC address. If you have port security on, and someone unplugs their PC (whose MAC address has been "learned" as secure by the switch) and connects a hub, as soon as ANY frame from another MAC is detected, the port will shut down. So you have to be sure you're not causing a support nightmare for yourself when you use this. Mike W.

This way I can have more routes to dynamically discover and more to troubleshoot. Has anyone done this before? If so could you lead me to some documentation on GateD?

RE: Rack [7:38796]
You have a couple options, the music racks already mentioned. I'll just add a little on that subject. Music racks. DJ equipment is also 19" wide, same as computer equipment. I looked at the Music racks. Some were at an angle, some were just odd looking. And there wasn't much cost savings. I found a vendor selling very cheap music racks on ebay for about $30. I considered them to be very limited in space, only a couple U of space. I wouldn't have been able to store all my current toys in a single music rack. I now have 5 2500's, 1 catalyst 5002, an isdn simulator box, a server, and 2 rack mountable hubs/MAUs. So your choice depends on how much equipment you can forsee yourself buying. Telecom Equipment Racks. They are 19" wide, and come in many sizes. A local vendor, Rexel Southern, had several 7' Chatsworth racks in stock. They bought in bulk, and I was able to get a great deal without paying shipping. My 7' black rack cost me about $115. I would look around your city, and see if you can find a telecom vendor if you want to look for a telecom rack. The 4' racks were about twice the cost, they could sell the 7' cheaper because more people bought them. -Jason www.CCIEwannabe.com - Affordable remote Cisco lab access Message Posted at: http://www.groupstudy.com/form/read.php?f=7&i=38857&t=38796 -- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]

I got my number this past weekend in RTP. #8960 This was my first attempt and thankfully, my last attempt for this track. I would especially like to thank Brian Dignan, CCIE #8248. He was a tremendous help in getting me ready to pass the first time. My company actually promised me 100% support for CCIE training when I got on board but the past 2 years, I ended up without any of the promised training. So I needed to prep with my own fund (meaning, I had to ask my wife for the money) :-) and I needed a lot of help on many subjects that I normally don't deal with every day. Especially on DLSW, TR and IPX. Brian took the time to explain these technologies and made the complex topics, easier to understand. I believe Stan earlier has already mentioned that Brian has started teaching his own Cisco and lab prep classes in the DC metro area. I also recommend Brian 100%. Anyone that would like to reach Brian can do so at - [EMAIL PROTECTED] As far as the books, I mainly used the same books as others, Bruce Caslow's book, Doyle 1 and 2 and CCIE practical studies. And Halabi book for BGP. I mainly used the free labs, labs from the books and also used lab 1 from Networkforce.com Thank you Paul for creating the list and all members on this list. - Paul Jin CCIE #8960 - Do You Yahoo!?

Re: Reposting: MTU figures ? [7:39301]
1500 bytes is the Ethernet frame without the header and CRC. It's the maximum amount of data the upper layer can stuff into an Ethernet frame. It's the payload in the Ethernet frame. When books refer to the Ethernet MTU as 1518 bytes, they are including the following: destination address = 6 bytes source address = 6 bytes length or EtherType = 2 bytes payload = 1500 bytes (for example, a TCP/IP or whatever packet) CRC = 4 bytes You may see 1514 too. Sometimes, books don't count the CRC. You may also see the 8 byte preamble before the destination address included. Technically, the inter-frame gap after the frame could also be included. And then there's MPLS and VLAN tags that can get thrown into the mix too. At the most basic level, however, understanding where 1500 versus 1518 comes from is essential.

A 2901 will set you back $1400 or so and it still won't have ATM, FDDI, or an RSM. It makes a lot more sense to get access to a switch at work or rent some rack time; I decided to take the switch class.

I didn't realize you could use 2500 series as the frame relay switch. If this is the case I'll spring for the extra $300 for a 2520 with 4 serial interfaces. This way I could use it as a FR switch for the future "almost real world" practice. Thanks alot.

RE: framerelay between 2501 and 2611 [7:39617]
You can do Frame Relay with two back-to-back Cisco routers of any type. Well, there may be some exceptions, but certainly a 2501 and 2611 should work. It's not very "real world" but it's cheaper than 3 routers. Priscilla At 11:32 AM 3/27/02, Lomker, Michael wrote: > > I think the question is as clear as can be.

You may be confused because some people use "broadcast" when talking about sending Ethernet at the physical layer. A coaxial cable is sometimes called a broadcast medium because the bits radiate out from the sender and reach all senders on the cable. It's an unfortunate use of the term that has been carried into generic discussions of Ethernet, despite the demise of coaxial-cable based Ethernet. Broadcast means a frame addressed to FF:FF:FF:FF:FF:FF. Switches forward these frames to all ports. They forward unicasts only to the correct port once they learn the location of destinations. A hub, on the other hand, forwards all bits without regards for the destination address. This is networking 101. Do you know about the CCNA study list? You should join that list.

Re: BootP Probs [7:39532]
I would suspect the printers also. One other thought I had was that it would be possible to misconfigure routers such that there was a "helper address" loop! The helper address should point to the actual server (or a directed broadcast for the network that a server is on). But a newbie Cisco person might think it should point to the next-hop router. Then that router could point backwards due to a misconfiguration. And you could get a loop and see a result like your 16 hops. I doubt that this is your problem, but it could be. Please let us know what you discover. This is an interesting quandary. Thanks.

RE: Where do I start? [7:39553]
I don't believe that Sybex is junk. Most of their stuff provides a good background for people who are new to Cisco and need things explained in a way that they'll understand. When I started working with Cisco equipment years ago and started the certification track, Sybex worked great for me. Even some of their CCNP series books are really easy reads just to get a feel for things and learn the terminology. However, I personally prefer the Cisco Press books at this point because of the detail they go into. Just my opinion.

My advice is use a lot of different sources, use books or white papers, everything else, is just a waste of time and money. Here is my assessment of what I used for Routing, which is hard but covers the basics; Most people start with routing. I am going in the order Routing, Switching,CIT then BCRAN. Cisco White papers and other documents found on the net- Great Sybex - Junk, a waste of paper. Surprisingly the questions are good Exam Cram - Way to easy, but if you want to have an outline its OK - junk Cisco Books- Good covers what you need to know. 2501 Router 16/16 with Cisco 12.x Firewall IOS and DES - Great See, the problem is, the CCNP covers a lot of material. IF you were to write a book that contained every detail you needed to know for real life, it would be 12 feet tall. So the 11 and 3/4 feet that are left out, are left up to you to find. Buy some routers, buy books only, doesn't matter which ones really. Compare what you read in one book, to another.

I am a technical reviewer for a book, and someone wrote that TCP/IP was written by the Depertment of Defense. I am confident that ARPAnet was commissiond by the DoD in the 60's to BBN, and maybe TCP/IP was derived from these early protocls, but to say the the DoD, or BBN or anyone other than the Internet community wrote TCP and IP would be incorrect, right?

Some Email servers (e.g. Exchange 5.5 and 2000) use ESMTP and balk when it is disabled. -Original Message- From: george gittins [mailto:[EMAIL PROTECTED]] Sent: Wednesday, March 27, 2002 11:16 AM To: [EMAIL PROTECTED] Subject: pix and e-mail problem [7:39643] For the past months i been receiving multiple e-mails from the outside world.

Re: how to deal with this message on pix? [7:39497]
You can go to a site called www.samspade.org to find out more about a
specific address. Sam gives you contact information of who/what ISP is
hosting, names, phone numbers etc.
I would recommend hitting your own network as hard as you can (after you
get written permission from someone in the CIO capacity) and see the
reaction that your defenses take, this will shed a lot of light on
what's going on.
Also, if you want to go real deep, check out www.sans.org they have a
great reading room for security threads.

Re: NAT Order of Operation [7:38021]
I have to eat my words in public! I just had a go (IOS 12.0) at the overlapping NAT example from the Cisco BCRAN book, and after minor mods, the config worked like magic. The outbound packets were indeed routed before the destination address was known, incredible. Marc Marc Thach Xuan Ky wrote: > > John, > I have never had great faith in that page.

RE: how to deal with this message on pix? [7:39497]
I had a similar 'self-inflicted wound' a while back. Seems some dope (that would be me) had retired some public IP ranges on the inside and needed to (temporarily) route those to null from his inside router. Otherwise, the hapless administrator saw these udps denied with the dreaded 'xlate' error, as his router was cheerfully sending the packets out the default gateway --- the PIX inside interface. Note the PIX does not, as aforementioned, route. Sooo, I'd look at that outside router, and maybe any inside route tables you might have. Best, G.

Sorry to point out the obvious, but any book on CCNP is going to be confusing. My trick was to use a bunch of sources, White papers I found snooping around on Cisco's Site and the internet. My advice is use a lot of different sources, use books or white papers, everything else, is just a waste of time and money. Here is my assessment of what I used for Routing, which is hard but covers the basics; Most people start with routing. I am going in the order Routing, Switching,CIT then BCRAN. Cisco White papers and other documents found on the net- Great Sybex - Junk, a waste of paper. Surprisingly the questions are good Exam Cram - Way to easy, but if you want to have an outline its OK - junk Cisco Books- Good covers what you need to know. 2501 Router 16/16 with Cisco 12.x Firewall IOS and DES - Great See, the problem is, the CCNP covers a lot of material. IF you were to write a book that contained every detail you needed to know for real life, it would be 12 feet tall. So the 11 and 3/4 feet that are left out, are left up to you to find. Buy some routers, buy books only, doesn't matter which ones really. Compare what you read in one book, to another. Its better to know it well, and be able to show you skills at the jobsite, then it is to rush. Once you get started and learn a few thing, the terminology will not be so confusing. -Original Message- From: Yomi Thomas [mailto:[EMAIL PROTECTED]] Sent: Tuesday, March 26, 2002 1:37 PM To: [EMAIL PROTECTED] Subject: Where do I start?

Also, go to "c c x x p r o d u c t i o n s . c o m" and click on the "Recommended Reading" link at the bottom of the home page. This may help you out.

[7:39553] Yomi, I understand your plight. (Feel your pain) Depending on your level of experience with (actual hands on time) you will need to start with a solid foundation of RFC's. If you would like to save a lot of money start with CCIE Study Guide by Hutnik / Satterlie go to half.com and buy used for 29.00us. When you get to a standards based question go to the appropriate RFC. I would also recomend purchasing the Cisco Documentation CD. But as Chuck stated hands on is the key I am a totally unauthorized instructor (unbiased)and recommend 30 - 40 hours of hands on prior to taking any test. There are a number of lab resources available for rent. Todd Lammle www.lammle.com or http://www.routersim.com/ has published an excellent Virtual Lab for CCNP. Hope this opinion helps. Terry L.
