Cisco 3005 VPN concentrator issues. [7:57495]
Hi all, Ive got a customer who has a 3005 concentrator connected to our network. He has setup a vpn connection which he accesses from home over the public internet. The problem he and the other 200 users are having is that they are loosing connectivity to the box intermittently throughtout the day. When he has loss of service, I can ping the vpn box directly connected to my network, whats even more strange, is that I can ping other customer hosts on the same subnet . Any ideas ?? Regards, Umar.

Re: O/T too much time on my hands? [7:57484]
Hi Priscilla, At the end of the slideshow you ask for other methods, well I've got one and it's really easy. Before I start you should note that my emoticons have broken down so you may need to insert your own. Unfortunately my first attempt to implement the method that I'm about to describe was error-prone and gave the answer as 31 triangles. Now, the shape is five-way symmetrical (which indicated that 31 was probably not correct), it's a five-point star with the pointy nodes joined together by extra links. We'll call the five pointy bits distribution nodes, and the five intersections in the middle we'll call core nodes. The area outside the shape is the access area. Now any given triangle can have either 3 distribution, 2 distribution / 1 core, 1 distribution / 2 core, or 3 core (except that the core isn't meshed so this is zero). We will abbreviate these types as 3D, 2D/1C, 1D/2C, and 3C because we like jargon. Inspection also shows that the 3D types can be subdivided into long triangles and fat triangles (3LD and 3FD) 2D/1C types can also be subdivided, into adjacent D's and non-adjacent D's (2AD/1C and 2ND/1C). With me so far? Good because we now subdivide the 2AD/IC into three subtypes: straight down, hanging left and hanging right (2AD/1Cbis, 2AD/1C(L) 2AD/1C(R)). Anyway all told we now have eight categories of triangle, we can count each category (please don't count the 3Cs during your leisure time). So by breaking the problem down this way, it is easier to count and thus much quicker to implement. In fact we now just have to count from one to five several times. Of course if we employed a project manager the probleem could be shared between seven triangle-counters working in parallel. This could bring the end-date in by a full ten percent. Disclaimer: Note that if working in a quality-assured environment you will need eight triangle-counters. The 3C type cannot be assumed to have no triangles. Time-savings shown are for example only and cannot be guaranteed. Just to close, there is a further refinement of the technique. Because the shape is five-way symmetrical, you in fact only have to count to one, what could be more straightforward than that? This has the added benefit of enabling the project to be broken up into even smaller and more manageable tasks. One more thing, perhaps it's a trick question. All nodes may run STP so all loops are removed, hence the correct answer could be zero. BTW if you were wondering about the access area, it's not actually relevant. rgds Marc TXK Priscilla Oppenheimer wrote: I added a Topology Troubleshooting Puzzle to my Web site. It's not Cisco-specific. Well, to be honest, it's not even networking specific! ;-) But it does make you think and wonder how you could be so blind, if you're like me when I first did it.

LRE 9E0-821 Exam [7:57508]
Has anyone taken this exam and PASSED? It requires a score of 888, and there is almost no material, other than what is on the Cisco site. I have no problem with this, but I had questions I could find NOwhere in the study material. I feel I know the material very well, but don't want to take the test again knowing they ask such obscure (and irrelevant) questions, without more study. If I'm studying American History and I know there's a test on the US Constitution, I don't expect to have to know the name of Thomas Jefferson's 4th child just because it's mentioned somewhere in the book.

Q in RIP. [7:57513]
Hi all, In the practice labs at the end of the book of CCIE prac studies by Karl Solie, I see a very common mention like the one below ( mostly I have seen under RIP routing, sometimes it also comes in other Routing protocol sections as well ) Make sure that no other routes are redistributed into the backbone. OR Don not allow any routes from the lab network to be advertised onto Backbone 1 To be more specific - the lab is Darth Reid Section V under item # 4. What exactly could be the configuration under this situations. The only thing that I could think of is NOT to include redistribute ospf 1 under RIP process. Is that all it needs or am I missing something else?

Re: O/T too much time on my hands? [7:57484]
Since this is not related to Cisco-specific nor networking specific, I have a different take at this puzzle. What I've seen is only four triangles and a trapezoid base. Other lines are just the reflection of the triangles... It's fun to hypothesize all the possibilities that the problem could be or should be, etc... However, it may not be a practical approach to solve complex problems. I'm in favor of the simplicity approach when it comes to solving problem.

Re: O/T too much time on my hands? [7:57484]
I like your methods. Since we're networking people, I think the best answer is, run the STP on it first, and the answer is: ZERO triangles! That wasn't really what I had in mind, but it's a good one!

Inspection also shows that the 3D types can be subdivided into long triangles and fat triangles (3LD and 3FD) 2D/1C types can also be subdivided, into adjacent D's and non-adjacent D's (2AD/1C and 2ND/1C). With me so far? Good because we now subdivide the 2AD/IC into three subtypes: straight down, hanging left and hanging right (2AD/1Cbis, 2AD/1C(L) 2AD/1C(R)). Anyway all told we now have eight categories of triangle, we can count each category (please don't count the 3Cs during your leisure time). So by breaking the problem down this way, it is easier to count and thus much quicker to implement. In fact we now just have to count from one to five several times. Of course if we employed a project manager the probleem could be shared between seven triangle-counters working in parallel. This could bring the end-date in by a full ten percent. Disclaimer: Note that if working in a quality-assured environment you will need eight triangle-counters. The 3C type cannot be assumed to have no triangles. Time-savings shown are for example only and cannot be guaranteed. Just to close, there is a further refinement of the technique. Because the shape is five-way symmetrical, you in fact only have to count to one, what could be more straightforward than that? This has the added benefit of enabling the project to be broken up into even smaller and more manageable tasks. One more thing, perhaps it's a trick question. All nodes may run STP so all loops are removed, hence the correct answer could be zero. BTW if you were wondering about the access area, it's not actually relevant. rgds Marc TXK Priscilla Oppenheimer wrote: I added a Topology Troubleshooting Puzzle to my Web site.

RE: FXS to key-system connection [7:57522]
Neil, I think that you can in fact connect a key sytem to a FXS port. If you have the book Cisco Voice Over Frame relay, ATM and IP in page 129 figure 5-13 it shows the connection of a a Key system via a FXS. Do a search on cisco web for Key System and you will see a few examples. Juan Blanco -Original Message- From: [EMAIL PROTECTED] [mailto:nobody;groupstudy.com]On Behalf Of neil K.

Re: FXS to key-system connection [7:57522]
Neil, I assume you are considering connecting an FXS VIC port to a key system. In that case you would connect to an FXO port on the key system. This would qualify as a trunk circuit connecting the two telephone switching devices. You are correct that this is not the best of possible connections. Dialtone is intended to be used as a signal between a machine, (a telephone switch) and a human listening to the telephone handset. It does not do well from machine to machine. In the analog world the best scenario for telephone trunk circuits is the EM interface. But, your key system nay not support that. Good luck with the FXS/FXO trunking. (Pay close attention to any calls that get refused, as it could indicate that digits are getting lost between the two systems).

RE: Q in RIP. [7:57513]
Without reading it, going on memory - it is saying the redistribute only the routes specified or required (maybe will affect IBGP later etc), deny all else. One of the things that those labs require is to use a route-map or a distribute list out/in (depending on the igp)for redistribution. It's up to you which one you prefer. Under Rip (routes u are receiving from ospf) redistribute ospf x (metric) route-map test route-map test permit 10 match ip address 1 access-list 1 permit x.x.x.x x.x.x.x (prefix you want to redis into rip etc) I hope you were looking for something elementary. There is nothing really complex about those labs.

Re: Q in RIP. [7:57513]
Looks like a pretty straightforward CCIE type requirement to me comment or two below: -- TANSTAAFL there ain't no such thing as a free lunch Rajesh Kumar wrote in message news:200211151732.RAA31459;groupstudy.com... Hi all, In the practice labs at the end of the book of CCIE prac studies by Karl Solie, I see a very common mention like the one below ( mostly I have seen under RIP routing, sometimes it also comes in other Routing protocol sections as well ) Make sure that no other routes are redistributed into the backbone. OR Don not allow any routes from the lab network to be advertised onto Backbone 1 CL: and the question is? seriously, R3 interface E0 is connected to the backbone. The instruction is to prevent any sunets used inside the lab network to be advertised into the backbone. So how do you do or not do that? CL: filtering comes to mind. you have a number of options when doing so. without going in depth into the requirement ( which is a nice one to practice, if I do say so myself ) I would say that as you prepare for the lab, you should be aware of any and all filtering options. To be more specific - the lab is Darth Reid Section V under item # 4. What exactly could be the configuration under this situations. CL: that would be telling :- CL: seriously, you have a number of choices and a number of knobs that are applicable. how do you limit what routes are advertised into or out of an protocol or an interface? The only thing that I could think of is NOT to include redistribute ospf 1 under RIP process. Is that all it needs or am I missing something else? CL: be careful how your define interfaces in the OSPF process, for one thing. be careful about how networks are placed into the RIP process. think classful and it's implications. CL: this should be enough to start your research.

ccnp switching - capus network design [7:57534]
Hi All, Am reading ccnp switching exam guide (cisco press), I am very confused by the design example provided in the book. A provided design of typical switch block: L2 S1 L2 S2 (Layer2 switching) | \ / | | \ / | |\ /| | \ / | | /\ | |/ \ | | /\| L3 S3 --- L3 S4 (Layer 3 switching) - question is here \ / to core layer My question is why the direct link between L3 S3 and L3 S4 is required? Won't it be a bad design which would impose the potential of bridging loop? Since L3 switching is used, HSRP and routing protocol will provide enough route failure detection and redundancy function. Is this a practical design in the real world?

Re: ccnp switching - capus network design [7:57534]
You have to use it cause you need to restrict the local traffic in Switch Block instead of going through Core. As you can specify S3/S4 as root/secondary bridge, there won't be bridging loop. - Original Message - From: pauldongso To: Sent: Friday, November 15, 2002 11:19 PM Subject: ccnp switching - capus network design [7:57534] Hi All, Am reading ccnp switching exam guide (cisco press), I am very confused by the design example provided in the book.

RE: No fragmentation when you just gotta fragment [7:57322]
hmm I dont think the router will drop the packet.. TCP has something called path of MTU RFC 1191. A quick defintion The smallest MTU of any link on the current path between two hosts. This may change over time since the route between two hosts, especially on the Internet, may change over time. It is not necessarily symmetric and can even vary for different types of traffic from the same host. Priscilla Oppenheimer wrote: JJ Angleton wrote: If you've set the flags in the IP header to not allow fragmentation, and then you pass through in interface with a smaller MTU, what happens? When a router attempts to forward an IP packet onto an interface where the MTU is smaller than the packet and the Don't Fragment bit is set, the router sends back an ICMP Message: Type = 3 = Destination Unreachable Code = 4 = Fragmentation was needed and the Don't Fragment bit was set. The router also drops the packet. By the way, in a related question - I've looked all through the Cisco website and can't find what the standard MTU is for Frame Relay. I found this in RFC 3090: To avoid packet discards on the Frame Relay interface, the RECOMMENDED default Frame Relay MTU is 1564 based on a PPP default MTU of 1500 bytes. That's the default. You could set it higher, probably, but why bother if the end stations aren't sending anything bigger? ___ Priscilla Oppenheimer www.troubleshootingnetworks.com www.priscilla.com - Do you Yahoo!?
