RE: Dialer keyword in Snapshot Server cmd [7:28557]
Nick, I managed to do some experiment with my home lab. When I ignored the dialer keyword at the server side, the server end will not treat the routing updates (ie. sending of routing updates) as interesting. As a result, the idle timeout (default 120sec) will count down till zero. Hence, the server will disconnect the ISDN call after 120sec even if the snapshot active timer is not yet due. However, if the keyword is present, every time an update is sent, the idle time-out is reset back to 120sec and the ISDN link is kept up until the snapshot timer expires. From my observation, I think you can ignore the keyword if you are applying the snapshot on serial interfaces or any interfaces which doesn't dial out. Purely my guess.

It is used in conjuntion with dialer map snapshot command, which directs the string to dial etc. From what I understand its just one of the Cisco things, whereby you also have to put in the dialer keyword (as in Snapshot server 5 dialer) on the server end, but without the matching dialer map snapshot command (and also due to server keyword) it never dials out and its also not meant to dial out. hth Nick Shah Message Posted at: http://www.groupstudy.com/form/read.php?f=7i=28576t=28557 -- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
FW: Frame relay problems [7:28569]
Once you solve R1-R4 problem, that should solve R1-R3. On R4, remove the subi/f 0.1. Just work using the physical interface s0 and turn on inverse arp like what you have for R3.

Re: load balance 2 isp's-cisco [7:28430]
I suspect any protocol that you can do bandwidth and or delay statements, can easily balance those two circuits. Two equal cost paths in OSPF or EIGRP will give you per packet or per session balance, with failover. I'm pretty certain you will not be able to find an ISP willing to run BGP with you, but iBGP running as a adjacent process (within 1 hop or between those 2 ethernet Gateway interfaces) will give the same result without an IGP (connected becomes your IGP).

Re: Home lab - 2523 [7:27788]
I can't explain the 2523, but try the 2520, 2521, 2522. The 2514 is very expensive due to it's abililty to fuction as a dual Ethernet firewall via FW/IOS. As far as bang for the buck, a cheap 4000 or 4000M with an NP-4T has more appeal in a home lab scenario (possibly cheaper too).

Re: VLSM and IGRP into OSPF - Another Method [7:28567]
John, This surely peeked my interest as to why the secondary address solution wouldn't work so I mocked it up and as you noted nothing... I think my chain of thought made me think that as long as the secondary address was on the mask of the route being propagated to R1 then it should work. However, in the setup all the subnets(172.16.1/2/3.x) when defined under IGRP would be summarized back to the classful boundary 172.16.0.0. When this happens the router simply does not broadcast the update since the networks being advertised fall into the connected interface classful boundary. 00:53:38: IGRP: sending update to 255.255.255.255 via Serial0 (172.16.1.2) - (to R1) 00:53:38: IGRP: Update contains 0 interior, 0 system, and 0 exterior routes. 00:53:38: IGRP: Total routes in update: 0 - suppressing null update 00:53:38: IGRP: sending update to 255.255.255.255 via Serial1 (172.16.2.2) - (to R3) 00:53:38: subnet 172.16.3.0, metric=8476 00:53:38: IGRP: Update contains 1 interior, 0 system, and 0 exterior routes. 00:53:38: IGRP: Total routes in update: 1 once this is/was identified your only option to get the route to R1 is to disable split-horizon on R2's S0 interface that's connected to R1. This now allows the routes that would otherwise be filtered be advertised to R1. 01:02:51: IGRP: sending update to 255.255.255.255 via Serial0 (172.16.1.2) - (to R1) 01:02:51: subnet 172.16.1.0, metric=8476 01:02:51: IGRP: Update contains 1 interior, 0 system, and 0 exterior routes. 01:02:51: IGRP: Total routes in update: 1 01:02:51: IGRP: sending update to 255.255.255.255 via Serial0 (172.16.3.2) - (to R3) 01:02:51: subnet 172.16.2.0, metric=8476 01:02:51: subnet 172.16.3.0, metric=8476 01:02:51: IGRP: Update contains 2 interior, 0 system, and 0 exterior routes. 01:02:51: IGRP: Total routes in update: 2 However, I observed a strange occurrence in that R2 generates a 172.16.1.0/28 route that is also advertised to R1. How and Why? I'm looking into it.. When this happens then another requirement would be to use no ip classless (note: there is no 0/0, candidate defaults, etc..) to avoid the 172.16.1.0/28 route from being used so to avoid the obvious routing loop between R1 and R2. Very interesting results from the question as to why we had the 172.16.1.0/28 route generated from R2 to R1. Well after very simple process it become quite clear as to why the route was created. Simply put, although the 172.16.3.0/28 was configured on the R1 - R2 link in order for R1 to accept routes on the /28 mask.. the Primary interface still quite possibly would not pass that (/28) route information without being associated as having a /28 mask itself. I came to this conclusion by the debugs from R1.. R1# 01:06:27: IGRP: broadcasting request on Serial0 01:06:27: IGRP: received update from 172.16.1.2 on Serial0 01:06:27: subnet 172.16.1.0, metric 10476 (neighbor 8476) *** 01:06:27: IGRP: Update contains 1 interior, 0 system, and 0 exterior routes. 01:06:27: IGRP: Total routes in update: 1 R1# Notice the 172.16.1.0 route that was sent from R2 it the only route that R1 receives. this is that same /28 route that now allows R1 to also see the 172.16.2.0/28.

look into policy routing, so that you can direct un-established traffic directly to your dmz I trust you have an IOS with firewall feature set. I trust you are working hard on a comprehensive access-list to minimize the kinds of vulnerabilities you are open to. From a security standpoint, this kind of setup is strongly discouraged.

I am wondering if the session layer doesn't use network address, how can it establish a dialogue with other session layer in other host? I would probably disagree with Todd's statement, although it's taken out of context and you haven't given us enough information to say that the statement is definitely wrong. However, try to picture the numerous OSI pictures you have seen. Most of them show horizontal lines between a layer on one host talking to the same layer on another host. So the session layer talks to the session layer on the other host. That's probably what Todd was getting at. However, the pictures also show vertical lines. A layer calls on a layer below to provide services. Each layer offers services to layers above it. The session layer is an elusive beast that is not implemented much. But one example might help. NetBIOS is a session layer. On a Windows client, when you access a Server Message Block (SMB) server, NetBIOS has the job of setting up a session with the server. Before it can do that, however, it must find the address of the server. If it's a modern Windows network, then SMB and NetBIOS are probably running above TCP/IP and UDP/IP. So NetBIOS sends a DNS or WINS query to find the IP address of the named server. It then sets up a NetBIOS session with the server. Actually, first, the client sets up a TCP connection. TCP has port numbers. The client sends to the well-known TCP port for NetBIOS session (139) and use an ephemeral port on its side. These port numbers could be considered addresses at

Agree with Phil on that, especially with the 4000M - it will still run 12.1 code if you max out the memory, but they're not the cheapest. I have one that's configured with an NP-4T, NP-1E, and NP-1R - it's my 2513 look-alike with 2 extra serials. My strategy for a home lab is to make as many parts multifunctional and multi-interface as possible - less parts, more function.

RE: Does session layer protocol use IP address ? [7:28378]
Priscilla, I think you are being a bit too hard on the guy. He tried to do some real research, he is referencing other written material. I did some quick research and I am finding some information is clashing about it. I think sometimes it is hard to make the differentiate between the layers for certain constructs. I think perhaps, WHY NFS is so often put in the Session Layer is because it uses RPC. Also, NFS does do synchronization of files, which can be heavily argued as a Session Layer characteristic. I would say RPC definitely is in the Session Layer. NFS does synchronization, (remember the ancient days of keeping file consistency with UDP?) but looks like it might be at the application layer. I suppose that is where the confusion is. And since NFS definitely uses RPC, and there can only be ONE, perhaps NFS is truly just at the application layer. You could argue that it mountd that really allows remote mounting and nfsd just does synchronization. I think it is somewhat debatable and reasonable for him to think otherwise if so many other references point it to the wrong direction. I am interested in any reference, as that is how we make sure we did not mislearn something.

RE: x.25 and x.121 in the lab [7:28589]
From McGraw-Hill's BCRAN book, you can make a router with 2+ serial ports a mock x25 switch. Haven't done it myself yet, but here's the gist from the book: 1. enable x25 routing: router(config)#x25 routing 2. make the router perform line clocking: router(config-if)encap x25 dce Other routers at the ends will be router(config-if)encap x25 dte to make them get clocking from the x25 switch router. 3. define x25 routes: router(config-if)#x25 route interface See pp 409-410 of BCRAN Course Companion from McGraw-Hill, Thomas and Quiggle, for more info. . . hope this helps, -Sean.

passed CCIE written (longish) [7:28614]
I just passed my qualification test with an 83. It was not an easy test, considering the topics covered. However, I must admit that nothing on the test was beyond the blue print (from CCO). I must admit that being a CCNP is definitely an advantage when one goes for this test, the coverage is different, since more concentration is on theoritical topics, desktop protocols of course token ring SRB/DLSW/RSRB/etc. bridging, rather than the actual routing protocols. I would attempt to suggest a path that one may take (books etc.) while preparing for this test. This will apply mostly to CCNP/DP's one with experience (NP/DP level). Read : 1. Internetworking TEch. overview (CCO) this is an absolute must, however not many who have passed the test seem to refer to this. It certainly has no commands kinda info, but packet types, frame types, layers etc. are plentiful, and these are tested. 2. Caslow : I have mixed responses about caslow, no doubt it is a very good book, no doubt I couldnt have studied some of the topics without it, no doubt that it has a wealth of concentrated info, however one can bypass it. It is replaceable. 3. Read chapter on ATM LANE from LAN switching book by Kennedy Clark (Cisco Press). Its the best explanation one can get. 4. If a CCNP, read all the 4 books, read DLSW + RSRB + SRB papers from CCO. 5. Know the boot sequence the boot register in out. 6. Lou Rossi's Token Ring Paper 7. Dennis Laganiere's RIF examples (good examples) 8. CCO Blue print(probably the most imp. ), I used to go back and forth forming my own Q's about a particular topic. One can replace Caslow (for written, its an absolute must for LAB) by referring to all the above mentioned material. I would recommend taking Written almost immediately after CCNP, while the material is still fresh. And lastly, the most important is BOSON tests, especially 2 3, test 3 has now about 400Q's and that really tests most of the stuff. Experience with actual hardware is important, however I would think that Cisco doesnt rely on actual experience with hardware for this test atleast (NP/DP tests albeit do rely on experience) I would like to thank everyone on this group. now enroute to LAB, and also being part of the exclusive LAB study group (on groupstudy, where else :) Nick Shah Network Engr.

RE: Does session layer protocol use IP address ? [7:28378]
It's possibly an exercise in bad faith to continually reintroduce written materials that have been explicitly discounted by people who can make a legitimate claim to understand the context they were churned out in. In this case, the cisco materials often don't offer any substantiative reasoning for their arbitrary taxonomical assignents of protocols as far as higher-numbered layers of the osi stack are concerned (providing somewhat of a contrast to their treatment of better-scrutinized layers). I'm a little concerned though, about the following: In sentence 7, you place RPC in the session layer. Two sentences earlier, you cite NFS' use of RPC as a justification for assuming that NFS resides in the session layer. While it might be exactly an example of the discontinuities you cite in your first paragraph, one of the few straightforward parts of the out-of-control agglomeration of ideas assertions that constitute the concept of osi communications protocol layering as it appears in (english) print seemed to be the notion that services maintained at level X+1 use services at layers X, and do not (directly) interact with other X+1 entities. Am I missing something? In either case, some instances where treatments clash are rife with potential insight revelant ambiguities, while others are not. It's not clear that the certification prep treatments of this abstraction belong in the former category (most notably for their unignorably light treatment of upper-layer protocol characteristics), rendering them a dubious justification for a reasonable opportunity to think otherwise. I dread the day when all extant statements about a given topic are accorded equal weight (not least of all because I make statements about given topics and would find it hard to live with such a weighty burden).

[7:28378] Priscilla, I think you are being a bit too hard on the guy. He tried to do some real research, he is referencing other written material. I did some quick research and I am finding some information is clashing about it. I think sometimes it is hard to make the differentiate between the layers for certain constructs. I think perhaps, WHY NFS is so often put in the Session Layer is because it uses RPC. Also, NFS does do synchronization of files, which can be heavily argued as a Session Layer characteristic. I would say RPC definitely is in the Session Layer. NFS does synchronization, (remember the ancient days of keeping file consistency with UDP?) but looks like it might be at the application layer. I suppose that is where the confusion is. And since NFS definitely uses RPC, and there can only be ONE, perhaps NFS is truly just at the application layer. You could argue that it mountd that really allows remote mounting and nfsd just does synchronization. I think it is somewhat debatable and reasonable for him to think otherwise if so many other references point it to the wrong direction. I am interested in any reference, as that is how we make sure we did not mislearn something.

RE: Cisco WAN Certifications [7:28615]
Yup, it is retiring. First, they retired the WAN CCIE and now, they have finished off the rest. Not sure how valuable this cert really is now days. As far as replacement, not really sure if they will really come out with anything to replace it. The new C/S CCIE's written portion can be taken with the WAN switching option from what I hear. I think 50% of the test is general and is the same and the last 50% can be chosen among many different options and WAN switching is supposed to be one of them. Still, in the lab, no WAN switching equipment. just routers and lan switches.

Congratulation!!! I passed this exam as well, at the first attempt with a 75% 2 days ago. I used: 1) Lou Rossi's Token Ring Paper 2) Network Learning CCIE Written Prep Guide 3) CCIE Prep Kit from QUE I agreed with Nick this is not an easy exam.

It was not an easy test, considering the topics covered. However, I must admit that nothing on the test was beyond the blue print (from CCO). I must admit that being a CCNP is definitely an advantage when one goes for this test, the coverage is different, since more concentration is on theoritical topics, desktop protocols of course token ring SRB/DLSW/RSRB/etc. bridging, rather than the actual routing protocols. I would attempt to suggest a path that one may take (books etc.) while preparing for this test. This will apply mostly to CCNP/DP's one with experience (NP/DP level). Read : 1. Internetworking TEch. overview (CCO) this is an absolute must, however not many who have passed the test seem to refer to this. It certainly has no commands kinda info, but packet types, frame types, layers etc. are plentiful, and these are tested. 2. Caslow : I have mixed responses about caslow, no doubt it is a very good book, no doubt I couldnt have studied some of the topics without it, no doubt that it has a wealth of concentrated info, however one can bypass it. It is replaceable. 3. Read chapter on ATM LANE from LAN switching book by Kennedy Clark (Cisco Press). Its the best explanation one can get. 4. If a CCNP, read all the 4 books, read DLSW + RSRB + SRB papers from CCO. 5. Know the boot sequence the boot register in out. 6. Lou Rossi's Token Ring Paper 7. Dennis Laganiere's RIF examples (good examples) 8. CCO Blue print(probably the most imp. ), I used to go back and forth forming my own Q's about a particular topic. One can replace Caslow (for written, its an absolute must for LAB) by referring to all the above mentioned material. I would recommend taking Written almost immediately after CCNP, while the material is still fresh. And lastly, the most important is BOSON tests, especially 2 3, test 3 has now about 400Q's and that really tests most of the stuff. Experience with actual hardware is important, however I would think that Cisco doesnt rely on actual experience with hardware for this test atleast (NP/DP tests albeit do rely on experience) I would like to thank everyone on this group. now enroute to LAB, and also being part of the exclusive LAB study group (on groupstudy, where else :) Nick Shah Network Engr.

RE: Does session layer protocol use IP address ? [7:28378]
And since NFS definitely uses RPC, and there can only be ONE, perhaps NFS is truly just at the application layer. That is one of the sentences I wrote. You seemed to have missed that one. Although I suppose I was not as clear. Sorry. I agree with what you said or at least speculated that yes, there can only be ONE component of the particular layer. Which would imply that NFS is indeed at the application layer since it uses RPC which RPC itself is in the Session layer. NFS itself has synchronization issues which some have considered to be a Session Layer characteristic. I never said once that the USE of RPC means that it should be in the session layer. I did mention that the fact that NFS has synchronization primitives, which is considered a characteristic of the Session layer. So that is the possible two sides. I did not take a particular side, and perhaps I should work more carefully with nfsd. I do know that the final application uses mountd, which hooks into NFSd. NFSd alone will not let you do a remote mount. Hope that clears things up a bit. This sure seems as debatable as whether or not ARP should be in Layer 3 or Layer 2.

RE: RIP routing (2 router lab) newbie [7:28327]
I spent a bit more time looking into this one than it may be worth. But my look did reinforce some points made in this thread and in another thread started by John Neiberger and researched so ably by Nigel Taylor - that is, the nature and behaviour of secondary addresses. Sorry I am unable to document everything I did here. It would take me writing a Jeff Doyle type chapter on RIP to get it all out and explained, with screen shots etc. To put things in terms of how I observed them: In the case of RIP, by default, advertisements are sent out an interface using the primary address of that interface as the source address. if another router on the segment is using and address that is not on the same subnet as the primary, that router will see messages like this: 01:46:25: RIP: ignored v1 update from bad source 172.29.101.1 on TokenRing0 01:46:30: RIP: ignored v1 update from bad source 172.29.101.2 on TokenRing0 01:46:35: RIP: sending v1 update to 255.255.255.255 via TokenRing0 (172.29.103.7) 103.1 was secondary address on my R1, 103.7 the address of my R3 You can see the error referring to 101.1 and 102.1 ( the address of another router on the segment ) I threw in a no ip split-horizon command on the interface of my R1, and lo and behold, it started sourcing rip packets from 101.1, 102.1 and 103.1 and all my RIP routes propagated from CCO: Note If any router on a network segment uses a secondary address, all other routers on that same segment must also use a secondary address from the same network or subnet. some of us already commented about issues with secondary routes among the various routing protocols. the point being that using secondary addresses can be tricky, and is probably not a good idea for newbies just trying to learn the basics. if you want to see how things work, use loopbacks. with secondary addresses, it is to easy to end up fighting with some complex issues beyond a beginner's understanding. in fact, there are some advanced students who find this topic complex and mysterious. best wishes. Chuck BTW, one of the implications of this study was a walk down memory lance. A guy named Bob Vance who used to hang here a lot and who was the progenitor of a number of interesting discussions once postulated that all stations on a segment will see the all F's broadcast, even if their layer three addresses are different ( i.e. seconday's ) the output above is something of a proof of that supposition. The router saw the RIP packets with the destination address of 255.255.255.255 ( MAC .. ), processed the packet, saw the source address as being on a different subnet ( even though on the same segment ) and rejected the packet. Interesting. Especially in that all subnets were part of the same Class B network. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Logan, Harold Sent: Friday, December 07, 2001 6:21 AM To: [EMAIL PROTECTED] Subject: RE: RIP routing (2 router lab) newbie [7:28327] It looks like Anil wants to get RIP to advertise the 193.9.200.0 network. A secondary address may work on one of the interfaces, but it would need to be on a different subnet. Notice from the config, he gave the secondary address the same IP as the primary addy. No matter what he does with the 193.9.200.0 network, those two routers will always show it as being Directly Connected instead of learned through RIP; DC routes have an administrative distance of 0, whereas RIP has an AD of 120. In the routing table, the router is only going o show the route with the best (lowest) distance. He could add a loopback on a different subnet on one of the routers, then add network statements for that subnet, and then he would see that network learned via RIP on the opposite router. Likewise Anil, if you had a 3rd router connecting to one of your two routers by the BRI port, that 3rd router would learn of the 193.9.200.0 network through RIP.

RE: Does session layer protocol use IP address ? [7:28378]
Thanks for the clarification. The two sets of beliefs appeared to be in conflict; I was focusing on the seemingly untenable one. Since I was parsing top down, it wasn't necessarily clear what your position was. However, you therefore appear to be reasoning through the issue of matching individual protocols to appropriate OSI communications protocol layers. In the post you were directly addressing the objection was not to incessant re-introduction of (some of these) sources into the dialog because they provided conflicting information, but because they arbitrarily associated these apparently pairs without any apparent effort at thinking through why those associations might be true. Sorry about qualifying my statements about the truth or falsehood of a given association, but i'm only at RFC 819, and it's going to take a long, long time before i get to peruse the ISO OSI documentation make even a bad guess (I'm really hoping that they're free by then).

OT: who do you trust: WAS: RE: Does session layer protocol use [7:28642]
This is probably as good a place as any to broach one of my pet peeves - that being the reliability of the information one gets in ANY of the study materials most of us use. We've had conversations here in the past about some of the more bizarre proclamations one can find on CCO, for example. I recall one I posted here a couple of times in the past, one which states that the max diameter of an EIGRP network is 224 because of the TCP limit on how far packets can travel. ( No I can't locate the link now, and I have better things to do than search for it again ) the point being that unless one is already expert in the material, how is one to know whether or not a given statement can be accepted, or must be questioned? Let me give a good one I just read in Large Scale IP Network Solutions, a Cisco press book with the letters CCIE prominently displayed on the binding, just below the words Cisco Professional Development In other words, yet another of the Cisco Press books which purports to help one along the road to the CCIE. Quote: The only route RIP understands as the default route is 0.0.0.0. It carries this route by default, which means you do not have to specify it. For RIP to advertise a default route, it must find a route to the 0.0.0.0 network in its routing table. OK. I understand what is being said. Now consider the following: R8R7R6---R5 10.1.1.0/24 192.168.1.16/28 192.168.2.48/28 relevant configuration for R7: interface Serial1 ip address 10.1.1.7 255.255.255.0 clockrate 200 ! interface TokenRing0 ip address 192.168.1.17 255.255.255.240 ring-speed 4 ! router rip network 10.0.0.0 network 192.168.1.0 ! ip classless ip default-network 10.0.0.0 R7# R7's routing table: * 10.0.0.0/24 is subnetted, 1 subnets C 10.1.1.0 is directly connected, Serial1 192.168.1.0/28 is subnetted, 1 subnets C 192.168.1.16 is directly connected, TokenRing0 R192.168.2.0/24 [120/1] via 192.168.1.18, 00:00:03, TokenRing0 R7# note that 10.0.0.0 is marked as the candidate default network, based on the command ip default-network found in the configuration above R6 routing table: Gateway of last resort is 192.168.1.17 to network 0.0.0.0 R10.0.0.0/8 [120/1] via 192.168.1.17, 00:00:15, TokenRing0 192.168.1.0/28 is subnetted, 1 subnets C 192.168.1.16 is directly connected, TokenRing0 192.168.2.0/28 is subnetted, 1 subnets C 192.168.2.48 is directly connected, Serial1 R* 0.0.0.0/0 [120/1] via 192.168.1.17, 00:00:15, TokenRing0 R6# Huh??? where did the quad zero come from? The only thing I have going is the default-network command on R7. No static to quad zero. R5 routing table: Gateway of last resort is 192.168.2.49 to network 0.0.0.0 172.29.0.0/24 is subnetted, 4 subnets C 172.29.200.0 is directly connected, Loopback0 C 172.29.3.0 is directly connected, TokenRing0 C 172.29.2.0 is directly connected, TokenRing0 C 172.29.101.0 is directly connected, TokenRing0 R10.0.0.0/8 [120/2] via 192.168.2.49, 00:00:08, Serial1 R192.168.1.0/24 [120/1] via 192.168.2.49, 00:00:08, Serial1 192.168.2.0/28 is subnetted, 1 subnets C 192.168.2.48 is directly connected, Serial1 R* 0.0.0.0/0 [120/2] via 192.168.2.49, 00:00:09, Serial1 R5# Huh?? Again, where exactly did this quad zero come from? now if you follow the path of the 0.0.0.0 routes in the various routing tables, you see that R5 shows 0.0.0.0 going to R6, and R6's 0.0.0.0 points to the interface where lies R7. But nowhere in this pod is there any reference to an ip route 0.0.0.0, nor does the 0.0.0.0 route appear in R7's routing table, whence originates the default route. My read on this is that Cisco's implementation of RIP will indeed interpret a default-network statement as an equivalent of the quad zero route and therefore will perpetuate it. But that's not what this CCIE level book says. In fact, it says something which would lead one to conclude that RIP should not behave this way at all. I suppose I SHOULD grant the possibility that older IOS versions do behave as the book describes. I'm using 12.1, and I do know that many things changed in 12.1, including some things that many of us take for gospel because we have proven them in earlier IOS versions. So what's a body ( not to mention mind ) to do? My point being that it is not easy for those of us who were not involved in the working committees of the CCITT or the IETF to really know how to judge the secondary sources we read. Cisco in particular, and especially in the certification game, presents itself as the ultimate authority on a lot of things. I daresay Cisco makes great effort to produce products and software that is standards compliant. So why does stuff like this happen? Because the people who read the RFC's and write the books are not conversant with the code designs and code operations that were written into the IOS? things that result in a behaviour

RE: voice problem [7:28621]
First I would look at the fragmentation of the voice packets; specifically serialization delay. Serialization delay = frame size (bits) / link bandwidth (bps). With voice you do not want to have more than 150ms of delay. However on your 64k link you will be sending 1500-byte packets which takes 187 ms to leave the router over a 64 Kbps link using the previous formula. This will contribute to the bad reception. Also look at queuing and traffic shaping to improve performance.

Re: Redistribution Question [7:28374]

Donny From: Shah Nick Reply-To: Shah Nick To: [EMAIL PROTECTED] Subject: passed CCIE written (longish) [7:28614] Date: Sun, 9 Dec 2001 20:00:33 -0500 I just passed my qualification test with an 83. It was not an easy test, considering the topics covered. However, I must admit that nothing on the test was beyond the blue print (from CCO). I must admit that being a CCNP is definitely an advantage when one goes for this test, the coverage is different, since more concentration is on theoritical topics, desktop protocols of course token ring SRB/DLSW/RSRB/etc. bridging, rather than the actual routing protocols. I would attempt to suggest a path that one may take (books etc.) while preparing for this test. This will apply mostly to CCNP/DP's one with experience (NP/DP level). Read : 1. Internetworking TEch. overview (CCO) this is an absolute must, however not many who have passed the test seem to refer to this. It certainly has no commands kinda info, but packet types, frame types, layers etc. are plentiful, and these are tested. 2. Caslow : I have mixed responses about caslow, no doubt it is a very good book, no doubt I couldnt have studied some of the topics without it, no doubt that it has a wealth of concentrated info, however one can bypass it. It is replaceable. 3. Read chapter on ATM LANE from LAN switching book by Kennedy Clark (Cisco Press). Its the best explanation one can get. 4. If a CCNP, read all the 4 books, read DLSW + RSRB + SRB papers from CCO. 5. Know the boot sequence the boot register in out. 6. Lou Rossi's Token Ring Paper 7. Dennis Laganiere's RIF examples (good examples) 8. CCO Blue print(probably the most imp. ), I used to go back and forth forming my own Q's about a particular topic. One can replace Caslow (for written, its an absolute must for LAB) by referring to all the above mentioned material. I would recommend taking Written almost immediately after CCNP, while the material is still fresh. And lastly, the most important is BOSON tests, especially 2 3, test 3 has now about 400Q's and that really tests most of the stuff. Experience with actual hardware is important, however I would think that Cisco doesnt rely on actual experience with hardware for this test atleast (NP/DP tests albeit do rely on experience) I would like to thank everyone on this group. now enroute to LAB, and also being part of the exclusive LAB study group (on groupstudy, where else :) Nick Shah Network Engr.
