Re: IP Multicast Addressing
The 239.255.255.255 is the highest in that subnet. D class starts at 224 (1110) and then E class would start at 240 (). This makes the D class range of addresses: 224.0.0.0 through 239.255.255.255. Therefor if D class addresses are used for multicasting then the 239.255.255.255 address would be the last address in that range before falling into an E class address. Here are the ranges: A = 1.0.0.0 - 127.255.255.255 B = 128.0.0.0 - 191.255.255.255 C = 192.0.0.0 - 123.255.255.255 D = 224.0.0.0 - 239.255.255.255Here is the multicast range (I believe) E = 240.0.0.0 - 247.255.255.255 Hope I helped (and was right) =o) Mark Z...

Re: TCP/IP print through firewall
Hi, I may be way, way off on this but I'll take a stab. If everybody that uses the printer sits on the 10.0.0.0 network (ie. 10.0.0.100 and 10.0.0.200) couldn't you change the printers default gateway to be the 10.0.0.0 network?

The print reaches the firewall's address 10.0.0.1 and leaves the firewalls untrusted interface 50.50.50.50. The source IP is still 10.0.0.100 and it reaches the printer 100.100.100.100 just fine, because it's a public address. The printer replies back, but it's default gateway, 100.100.100.1 doesn't know where to route to network 10.0.0.0 so it gets dropped. If my firewall translates the address into it's public address 50.50.50.50, the printer will reply back to it, and I will need to do a "handoff" or NAT so that port 9100 traffic to 50.50.50.50 gets translated into 10.0.0.100 so my work station will get the reply. But, with this solution, the printer reply will end up at 10.0.0.100 if 10.0.0.200 tries to print too. How does this work?

What should I block???
Hi Group, I know that this is going to be very broad but just bare with me on this one. We are switching over our firewall router from a bay to a cisco. The cisco one that I am going to work on is already pre-configured except for access-lists and filters. What they basically told me is that the checkpoint device behind it will take care of all of the intense blocking and forwarding, but on this FW-router we just want to block the basic things that are usually not allowed through. Here's what I was hoping for. Just a basic list of things that are normally blocked on the router above the FW. For example, I know that I'm gonna set an inbound access-list denying telnet so that the checkpoint doesn't even have to worry about that. I am just looking for a list of services/ports/etc., that as a rule of thumb to you FW guru's, are usually denied. I know this is broad and I'll understand if I don't get much feedback. Gotta also find that whitepaper on FW's. Concidering this will be my first time coming anywhere near a FW (FW Virgin) I'm a little nervous and hope you guys can help out.

Network Management Program (which???)
Hey Group, Need some help on this one. I just came on as a contractor for this company. The network is somewhat small. They have around 186 routers worldwide and around 22 switches that they have to worry about. So all in all, there are around 200 managed devices for us to take care of. Currently they are using some program called "What's Up Gold". Personally, I hate this thing. It's not secure, the features are minimal, and I hate web based stuff. They have it set up on one machine and everyone access's it from the web to it's IP. The manager has expresed some interest in other methods but it will be hard to move him away from what there is now after he gets back in a week from a business trip. I would like to present a proposal on a new management system. My problem is that I have only worked in Openview before. I think Openview is awesome and gives you all the features you need and more. For this site though, I think it would be too much. I just don't think it's really needed for the size of this network and the management/configuration of it would overseed the network management itself. Basically, I'm asking what you guru's out there think I should present to use. Should it be CiscoWorks2000, Openview, or stay with What's Up Gold?

But isn't that the routers job???
Hey Group, Me again. I'm reading for my CIT and am at the section where it goes into detail of the various switching methods in the router (i.e., silicon, CEF, autonomous, etc.) I understand how all this works and understand how the SP takes a lot of the stress away from the RP and this is good because your avoiding bogging the RP/CPU down.

By using switching methods, the RP is free to use valuable CPU time on more important things than doing route lookups for every packet that comes in the router." Correct me if I'm wrong but isn't that what a routers supposed to do??? What else does the RP have to do that is more important than ROUTING?

3 down, 1 to go...(passed BCRAN)
Hey Group, Just wanted to share my victory today over the BCRAN. Went in very unprepared (first time going in feeling unsure) but still passed. I barely studied for this one and my score reflected upon that but I still knew my stuff and passed. I have to agree with the masses when I say that this test was very, very easy. I wouldn't even say that this was a 10th as hard as the switching or routing 2.0's. Well, I got one more to go (dreaded CIT) and then I can change my signature (it's about time) from CCNA, CCDA...to CCNP, CCDA. God I can't wait. =o) On a side note: The only thing I used to prepare for this test was Lammle's Remote Access. I personally feel this book was great. I barely studied and got a 762. If I had put more time into it I'm sure his book could have scored me in the 900s. I recommend it to anybody pursuing the BCRAN.

Not a problem, just a topic...
Hey Group, Just for the sake of topics and answers, here's one for ya. I'm cramming for my remote access and hit the big boy...Frame Relay. I'm bringing up the FECNs BECNs topic here. I understand what they are and how they are used and all that good stuff. The book says that when there is congestion on the line from point A to point B, the frame switch in between will send out BECNs to the sender (A) and also FECNs to the receiver (B) of the data being sent. Fine, no problem right. Here's my question, and I know I'm just bringing this up to argue but what the hell. Why does the frame switch send FECNs to the receiver telling him that that sender is sending too much??? This is my analogy...There's a production line in a car factory, if the first station was creating parts too fast for the second station to handle, you wouldn't see the site manager (frame switch) go out and tell the guy at the second station that there was a problem...he didn't do anything wrong right? I would imagine the manager just yells at the first station. Basically, why does the frame switch have to send FECNs to the receiver. I can understand the BECNs. It just seems like the receiver is getting a warning for being bad when it was all the senders fault. This may sound childish to some but I'm trying to write it so it's simple. Just thought I'd rant a bit and bring out some answers or opinions.

Dampening is a BGP feature used to minimize the instablility caused by a flapping link. A route that is flapping receives a penalty of 1000 for each flap. When the accumulated penalty reaches a configurable limit, BGP suppresses advertisement of the route even if the route is up. The accumulated penalty is decremented by the half-life time.

CiscoPress + what??? (BCRAN)
Hey group, As some of you recall my last post, I just passed my BSCN. I am now moving onto the BCRAN. For the Switching and Routing 2.0 tests I have used CiscoPress + Exam Cram books to get the passing grade. I really like the exam cram's for touch ups on these tests but I have read in many places that the remote access exam cram does not make the grade. I'm wondering if anybody has used this book and whether or not it is a good tool to add to the CiscoPress BCRAN. If not, should I use the CiscoPress BCRAN alone, or are there other good b0oks/materials to go along with it. Any advice would be appreciated.

Hey all, Well, I did it. Knocked the BSCN out of the box today. I didn't get the best score in the world but I did have plenty room to spare.

I have to say that this is the hardest test I have EVER taken. I thought I was failing it before I got even halfway through it. I guess that made it all the much sweeter when I saw "Congratulations" at the end. Next up...BCRAN and then the CIT...and thats it. Well, until the CID that is.

Re: OSPF and static routes
In a message dated 11/6/00 1:12:18 AM Eastern Standard Time, [EMAIL PROTECTED] writes: Had a problem today that doesn't make much sense to me. Very simplified layout (hopefully not oversimplified...) RTA -- RTB -- RTC RTB gets a summary LSA for a network, call it 50.0.0.0, from RTA. This summary LSA is visible with the command 'show ip ospf da su'. There is also a static route for 50.0.0.0 on RTB, with admin distance 1. Not surprisingly, this overrides the OSPF route in RTB's routing table. The static route is NOT redistributed into OSPF. RTB is adjacent with RTC. However the summary LSA for 50.0.0.0 does not get to RTC (as shown by 'show ip ospf da su'), and RTC has no route to 50.0.0.0 (as shown by 'show ip ro'). If the static route is taken off RTB, OSPF sends the summary LSA to RTC again, and an OSPF route to 50.0.0.0 shows up in RTC's routing table. I was under the impression that routing protocols are generally 'ships in the night' in their operation (in that they each work out what they consider to be the best route, and then the routing process chooses between routing protocols). Why does adding a static route (not redistributed) affect what LSAs OSPF sends? Shouldn't RTC get sent the summary LSA even though RTB has a better static route - how does the OSPF process on RTB even know about the existence of the static route?? Ok, let me try to work at this one with you. I may be false or short on some of this so somebody will correct me if I am wrong. 1.) The reason that router C is not getting anything from B (50.0.0.0) is because, and you said it yourself, it is not redistributed on that device. A static route has a lower admin dist. so it will be chosen. Therefor, the summary that would be normally sent to router C via ospf is over-riden by the static route which you have to manually place on router C. That's why when you take out the static route, router C gets the route back. OSPF see's a change in it's tables and recalculates. It see's that there now is a route to 50.0.0.0 via ospf and that there is no other route there with a lower admin dist. so it is chosen and propogated. I could be wrong or incomplete on this... 2.) You spoke of ships-in-the-night. Actually, I just read up on that in terms of EIGRP. In EIGRP there is support for 3 protocols: IP, IPX, and Appletalk. Inside of the EIGRP process, when it is running, these 3 protocols (if all used) don't have anything to do with eachother. They are kind of oblivious to each others operations and are in their own, lets say, platforms. This is what ships-in-the-night means. None of them are dependant on each other and they don't even care if the others exist. Hence the term "ships-in-the-night". I hope I helped with some of your questions. Somebody delve deeper, I know I didn't hit this completely...

HSRP priority bug???
Hey Group, Got an issue for you. I am faced with a dilemma here. We have a client who is about to make us upgrade about 100 IOS's to fix this issue and I just want to know if there is another way around it. We have a site with 2 redundant routers. HSRP is configured between them. The modle is Cisco 2612(Token/Ether) when we configure HSRP with a priority of 100 on the secondary router and 105 on the primary both of them get stuck in INIT. The rest of the network uses these settings and everything is nice and dandy. When we go onto these devices and try to set the priority to 100, HSRP does not work!?!? If we set it to 105, 110, 115, etc. it will work just fine but for some reason it will not except 100. Has anybody ever dealt with this problem or know how to fix it? I would really appreciate it if somebody could help us out or it looks like we will be working nights here if you know what I mean. Thanks in advance all...

Re: Who initiate backup link?
In a message dated 10/26/00 8:55:55 PM Eastern Daylight Time, [EMAIL PROTECTED] writes: My hunch is any router that detects link failure initiates isdn backup link first. am l right? Well, lets say at your branch office you had the config on serial 0 that I told you about where it specified that s1 was the backup interface (isdn). As soon as serial 0 dropped, serial 1 would come up/up and become your link untill the serial 0 came back. Serial 1 would stay up for that amount of time you specified (0 300) to make sure that serial 0 was back up for good. You could check on this by typing "show ip int brie". When this config is properly set up and serial 0 is up and stable you will see that serial 1 is not in a down/down state but instead in a standby/down state. This means it's on standby and ready to come up in case of primary failure. Hope this answers your questions...

A designer should be logical, analytical, and able to spend lots of quiet time thinking before implementing. (Some people aren't good at this! ;-) He or she should be aware of the technical details of many different solutions and be able to select the right solutions after figuring out what problems need solving. Skills include analyzing business and technical requirements, characterizing the performance of the existing network using network management and protocol analysis tools, figuring out typical traffic flows and loads (not easy on most networks!), developing a topological view of an internetwork, designing addressing solutions that conserve addresses and support summarization, selecting products for implementation, designing wiring schemes, testing the implementation, etc. (See the Table of Contents of my book for my opinion of what a designer should be able to do. ;-) Q2) What are the type of job or you can say job names for a "CCDA or CCDP" other than Network designer ..!! Network architect and network engineer are often other names for network designer. These are often the most senior-level people at companies. In some companies the network architects have formal PhD-level training in computer science, mathematics, queuing theory etc. This isn't always the case, of course, but at large ISPs and many universities it's true. Usually a network architect has had many years experience in operations and is well aware of configuration commands that will make the designs work. Q3) For the CCIE Design tarck or exam, is true that you do not need to know "CLI" commands (ex: BCSN, MCNS .. have many IOS commands ..etc" It is not true. You need to know the commands for the lab part of the test. If Yes .. is it true that a person how Pass CCNA, CCDA take the CID than jump to the CCIE Design tarck and pass it (write and Lab) can he have the CCDP "waved" or both the CCNP and the CCDP ? .. for the CCIE R/S I have red he can wave the CCNP and take the CID in order to have CCDP !!. To become a CCDP you have to take CCDA, CCNA, Routing exam, Switching exam, Remote Access exam, and CID. To become CCIE you have to take a written test and a 2-day excruciatingly difficult hands-on lab test. The CCIE exams are managed by a different department at Cisco than the Career Certifications. Despite some Cisco marketing material, there really isn't a stair-step relationship between Cisco Career Certifications and the CCIE program. Most people prefer to take the other exams first to get some practice, but it's not required. If you're a hot shot, it makes sense to go for the CCIE level first, since that's the most respected. Q4) Anyone who have a good drawing skills "have some good CAD skills ex:Autocad ver 9 to 2000 !! .." can this help him in his work or no need for it .. (as a Network Designer). It could help. Most of the network design tools support drawing packages that are pretty simple though. Figuring out what to put on the drawing is the hard part! Q5) I am working on the CCDA right now, but I did not know why is the Deign track "CCDA, CID exam" is hard from the other support "CCNA, CCNP" .. !! is it the Case study stuff !! As I can see no commands is need in the CCDA (DCN Cisco book) is it the same with the CCDP and CCIE Design track .. But in the Lab exams there are some names for routers .. any one take the CCIE Desing Lab. Q6) About the CCIE world wide any categories for there numbers "ex: How many CCIE WAN, CCIE Design ..etc" I say about 35% to 40% are CCIE R/S .. only a guess .. I think most CCIEs are R/S. My guess is the number is more like 80 %. Only a guess though. So that's my opinion anyway! I think it would be great if more people took the design tests and if more employers expected the design certifications. The idea that surfaces every so often that these tests are easier or less technical is based on false assumptions. Which is easier, to operate a car or to design

RE: 53-byte ATM cell (laymans terms)
(Here's that post I've tried to send a couple times...) If you are asking for a reason, I may be able to break it down to a basic. One of the reasons ATM uses a fixed cell size (53-bytes) is to make it a little faster. Lets look at it through the OSI model. When data travels down through the OSI there may be various size differences in different technologies (ether, token, FDDI). This of coarse produces thinking on the OSI's part as it flows down the layers. We all know thinking takes up some time. Well, with ATM and the fixed size, the lower layers know what is gonna come out every time so they don't have to rethink their strategies every time a different packet is sent through because they always know how big it will be (53-bytes). The less the thinking, the faster it can pass the info onto the line. I know this is very weak but this is how I was taught it and I think it helps to explain in Layman's terms. Think of it like this. If UPS didn't have to weigh their packages every time they sent it out in the trucks, just imagine how much faster it would get on the road.

300/1000 scale (correct me if I'm wrong butt...)
Hey Group, I always wondered when taking my tests what they meant when they said that there would be a 300/1000 scale. Then somebody on the list explained that you start out with 300 points automatically. This is nice. I just tried to figure out how many could be gotten wrong on the BSCN and came up with something that I don't believe. Follow me on this one... 61 questions, 690/1000 to pass. You start out with 300 so there is basically 700 points for a perfect score with 61 questions. Now, 700 points divided by 61 questions breaks out to something like 11.48 points per question. Then I take 1000 - 690 and get 310 points. This is how many you can miss and still pass. Finally, I divide that 310 points you can miss, by the number of points per question (310/11.48) and get this as the number of questions you can miss and still pass...27.003 (27 basically). I may be seeing it wrong in the area where I divide the 700/61 to get the number of points per question. It may be that even though you get 300, you still divide 1000/61, which would give you 16.39 points per question which in the end would allow you to miss 18.9 (18 basically) questions. This sounds alot more like it. This confuses me. If my initial calculation is the correct one, what this shows me is that on a test that has only 61 questions, somebody can get 27 (almost half) of them wrong and still pass the test. Does this just sound too easy to anybody else? Am I not understanding that 300/1000 scale thing, or is this test just soo damn easy? Don't get me wrong, I never go for the bare minimum. In fact, I don't believe anything under 800 is satisfactory (B basically), I just like to know all factors before a test. Thanks for responses guys/ladies...

BGP Route Decision Process (hmmm)
Hey Group, I am studying for my BSCN and am starting on my journey into BGP (luckily I left a trail of bread crumbs to get out) ;) What I'm saying is that for the next couple weeks you may see me asking more than the usual amount of questions. I have one on the BGP Route Decision Process. In pages 168 169 of "Internet Routing Architectures," it gives the steps through attributes it takes when deciding between multiple routes to a destination. I wont list all of them but if you have the book you know what I'm talking about. If every attribute matches all the way down the list to the last one, the router with the highest IP or Loopback address will be the chosen one. This I understand perfectly and I know that it usually wouldn't even get this far down the list but I find myself again playing the devil's advocate. What if the loopbacks on both devices were the same? I know you could just change one but let's say you didn't. How would it finally make it's decision? Let's pretend everything was the same...would it just, ummm, pick one? Would it kinda just spin a wheel and see what it lands on kinda like telco's do to give an RFO? ;) Thanks ahead of time for responses folks...it's appreciated. Love your show.

ATM... Why not STM? (just for fun)
Hey Group, I asked my teacher about this a long time ago when I was training and never got a real strait answer. (was always the one who asked the far out questions) I know I don't have the most solid concepts in my head on this but this is what I've been told. You have Asynchronous, and then you have synchronous. These are how info is sent across a line. 2 different ways. I was "told" that synchronous transmision is usually faster than asynchronous because there are less steps in it's sending process. Cool, still with me? Here is my question: If synchronous is faster, why don't they create Synchronous Transfer Mode (STM) on top of, or instead of using Asynchronous Transfer Mode (ATM). I don't want anyone to stress over this one, it's strictly to think and have fun with. I heard they are making it but my source was not reliable. I don't even remember who said it once. Just some thoughts group. Have a good start of the week... My 0.2 cents Mark Z. CCNA, CCDA, 1/4-NP **NOTE: New CCNA/CCDA List has been formed.

Re: ospf bandwidth question
In a message dated 10/3/00 12:16:20 AM Eastern Daylight Time, [EMAIL PROTECTED] writes: Hmm... not so sure about that. I'm told by an unreliable source (my telco :-) that if you're sending from a large access speed to a smaller access speed, traffic exceeding the CIR + EIR (i.e traffic that won't 'fit' once it gets to the smaller end) will be dropped as soon as it enters the telco network. It isn't transmitted across the telco cloud at all, and thus doesn't produce F/BECNs (or congestion). This may be telco-dependant behaviour, I guess. In this scenario of a larger bandwidth side trying to send into a smaller CIR you would have DE bits inbound on the smaller side router. DE (discard eligable) is any data sent over the line that is higher than the CIR because it is "eligable for discard". Let me guess...Worldcom told you that ;) On a side note. It's amazing how many new terms the telco can introduse into the field when trying to think of an RFO, haha My 0.2 cents...

Re: Secondary IP for Catalyst switches?

If so, once I logon (by console/telnet) to the switch, I can troubleshoot the connectivity to an attached PC/server by pinging its IP address (assuming the secondary IP temporarily added is the same subnet as this PC/server IP address.) This will help troubleshooting the functionality of the TCPIP stack of the PC/server, don't you think? Hey, Instead of going through all of this what I think you could do is try to ping the server from a router that is on the other side of the switch. It would make it through the switch because it (as you know) uses layer 2. This way you could test how it would probably run in a real world situation: PC-switch, switch-router, router-switch, switch to server. I don't know...this is how I would do it...I would also place a sniffer on one of the lines to break down the TCP/IP stack like you wanted.

1 down, 3 to go!!! (question) ;)
Hey Group, I just passed the BCMSN this morning with a decent score of 803/1000. I only studied for this test for a month and a week. I was scared that I was going to fail it because this was the first time I scheduled a test before even finishing a book. I guess I gave myself a deadline, which I am not going to do again. I need to relax ;) I have a question now. I want to go for my BSCN but it's still not out (cisco press). I know I can read the ACRC and a couple others but I just feel better when I have the new stuff. I did a search and found this book. I have seen them around and have the CCIE all in one study guide by them but I don't know how their credibility is. Here is the info "McGraw Hill Text; ISBN: 0072124776" This is a BSCN book but if it's not good I will just go with the BCRAN and wait for the big one to come out.

Hey Group, This has now officially gotten to me!!!

Figure this one out!!! (damn telco)
Hey Group, Got another issue for you all to give opinions on. We have a client's router attached to the telco's FR cloud. We seem to have a problem with strickly the ping command. When we ping an IP in the telco's net, we get dropped packets. Maybe 60% will go through. Then maybe 100%, and so on. When other traffic goes through the line everything is normal. The telco said that there is not a problem on their side and they don't see anything wrong (as usual). We have looked at everything, ACL's, CIR's, DE bits. We cant figure why this is happening and why packets are being dropped, especially at the low rate of traffic that is being sent. It almost seems like when you grab a water hose and bend it to stop the water from flowing and then let it go the let the water flow again...strange stuff. What do you all think.

Re: Figure this one out!!! (telco was wrong)
Hey group, Thanks for the help I got from you. We wound up getting on the phone with telco and worked through it with them. They said that they were seeing 140% overutilization for the CIR on that link and when we would look at our show command we saw, for 3 minutes 16,000 bytes sent. Our CIR is 16K PER SECOND! We were doing 16k for 3 minutes and those geniuses at telco, who were watching the link at the same time we were, said that it was at 140% over. How does that add up??? Well I've learned something very valuable in my first week of work in this field...NEVER TRUST, LISTEN TO, REASON WITH, OR TRY TO UNDERSTAND...who?...you guessed it...TELCO!!! By the way, after about 20 minutes he says, "Oh, wait a minute...now I'm seeing something strange from that device...I'll have to re-route this one" So tickets closed. Thanks for the help again guys. I'll wait a little longer before posting these for now on.

Watchdog Timer (restart)???
Hey Team, Here is a piece of the show ver command: Atlanta_1 uptime is 10 minutes System restarted by watchdog timer expired at 05:59:11 pdt Tue Aug 15 2000 Here's the deal. We manage net's for various clients where we get snmp tickets from our clients. We got one that said Cisco Up with reboot. We get these often but this one said the cause was due to a watchdog timer expiring. Nobody in the office can figure out for sure what this is. I went to CCO and got this from them on the watchdog timer: "Hardware or software mechanism that is used to trigger an event or an escape from a process unless the timer is periodically reset. See also watchdog." and now watchdog: "Watchdog timer manager that runs on the NP of each LightStream 2020 ATM switch in an ATM network. The watchdog process rearms the watchdog timer so that the system automatically restarts if the NP fails." Seems simple enough right? Here's the catch. This happened on a 2610 router and I doubt it's running ATM at all. Could someone please help us out and clarify what this is so I can close this damn ticket ;) Thanks team, Mark Zabludovsky ~ CCNA, CCDA UNISYS e-@ction Network Managment Services [EMAIL PROTECTED] ___ UPDATED Posting Guidelines: http://www.groupstudy.com/list/guide.html FAQ, list archives, and subscription info: http://www.groupstudy.com Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
