AW: ISDN simulation [7:7489]
to really play around with ISDN, you need a BRI or a PRI (if you are at home, not that cheap). You need an ISDN Network to use your ISDN interfaces, to build one by your own will be difficult. -Urspr|ngliche Nachricht- Von: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]Im Auftrag von Thomas Gesendet: Donnerstag, 7.

MLS and InterVLAN routing question [7:7498]
I have three (stupid) questions in regards to MLS and Inter-VLAN routing - sorry :) thanks so much for your help in advance. I understand that in order for MLS to work, one will need: For Cat 5000 or 5500: Either i) RSM (for internal MLS-RP) or ii) with a NetFlow Feature card and directly connected to an external Cisco 7200, 7500 or 4700 router for (external MLS-RP) And for Cat 6000 or 6500: i) MSM (for internal MLS-RP) Now, my question is: Q1) For Cat 5000 or 5500: when do you have to use a Route Switch Feature Card? Is it the same as a RSM? Q2) For Cat 6000 or 6500: what is a MulitLayer Switch Feature Card? Is it the same as a MSM? Q3) As for MLS and Inter-VLAN routing, if an external router is used, does the router need to be attached to the switch using mulitple Ethernet connections or by a FastEthernet connection using ISL, in both cases of MLS and Inter-VLAN routing?

Re: Layer3 switch vs Router [7:7406]
Jason, the real answer to your questions is this. first why do we use layer 3 devices.. well MAINLY for intervlan routing,,,we are all agreed...yes then , we migh have these two different setup`s. a 6500 with an internal MSFC on a sup 2G... and a 6500 with an external router ...a 3620..with GBIC and 32 meg if ram(base spec) AGGREED the only real difference is.latency...and space YES i know the specs don`t equate BUT i am answering his question... in a perfect world both setup`s would be identical ...if that was the case then 1. you need more space having 2 seperate devices... 2. you will suffer from a slight speed differnce with the msfc sending info over the cat`s inbuilt backplane..3 gig and you sending info over the 1 gig link form switch to external router...this is ALL... forget packets/bytes/bits per secondthis is where your speed in/decreases are seen .

Re: Layer3 switch vs Router [7:7406]
Chuck, Reflecting on my post, about the only thing that could be proven is that they seem to call most of their newer/higher end models switch-routers.. I don't know if looking at the PPS is a great indication just because technologies change and get better.. So I can't say that the higher PPS of the 12000 and 8500 are due to multilayer switching only I have alot of respect for you, so I don't want you to feel that I'm trying to contradict you to make you look bad or anything I don't even think it's possible for me to make you look bad =) The whole point of all of this stuff was tho that Multilayer switching is a great thing =) Mike W. Michael L. Williams wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]... I think on any of those units, to reach it's maximum throughput you have to enable and configure multilayer switching. If you look at the name on the Cisco 12000 you'll see it's called a GSR = Gigabit Switch-Router. At this point, even Cisco realizes that it's incorrect to call it simply a router because anymore the combinations of switches and routers have been combined. The real funny thing is, out of all of the units you listed, Cisco only calls one of them a (plain) router, the 7600. The others are refered to as either a switch-router or a multilayer switch. So, you'll notice the only router listed here can do 30 million PPS, while the two high end switches can do almost 6 times (170 mPPS) and then over 12 times (over an order of magnitude more) than the actual router... so thank you for proving my point. =) Having said all that, my whole point is multilayer switching integrates the best of routing and switching to provide better performance.. and I think my point has been proven. I wish I could log into CCO =( Mike W. Chuck Larrieu wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]... So layer three switches are faster, 'eh? By orders of magnitude, 'eh? This calls for a bit of research on CCO. Hhhmmm Catalyst 8500 = 24 million PPS http://www.cisco.com/univercd/cc/td/doc/pcat/ca8500c.htm#CJAEJHDF Catalyst 6509 = 170 million PPS http://www.cisco.com/univercd/cc/td/doc/pcat/ca6000.htm Cisco 12000 = 375 million PPS http://www.cisco.com/univercd/cc/td/doc/pcat/12000.htm Cisco 7600 - 30 million PPS http://www.cisco.com/univercd/cc/td/doc/pcat/7600.htm so it would appear, based on Cisco's own product literature, that high end router versus high end switch, the edge most definitely goes to the product Cisco calls a router. and numbers are all over the place, to judge from the example I have looked at. Look, my point remains that any trickery, hardware or otherwise, can be applied to routers as well as switches. It most definitely is NOT enough to say that there is a difference and it is because of the hardware construction of a switch versus that of a router Chuck -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]] On Behalf Of Michael L.

I am sorry, should have said some thing meaningful. :( hypothetically speaking, if the ACLs are in place, wire speed is gone. The concept route one switch many is no longer holds its value. That's what I thought you meant. I'm glad you clarified your position. But it's incorrect. Multilayer switching ( therefore wire speed routing) are out the door only when you have an ACL applied to the MLS-RP interface as an incoming ACL. That's it. This is where flow masks come into play. There are 4 situations that need to be considered when using ACLs and Multilayer switching: 1) Where there is an incoming ACL on the MLS-RP interface, Multilayer switching is out the window because every incoming packet must be examined by the router. 2) If there is no access list, you can use a Destination IP flow mask, the simplest of the flow masks, where only the destination IP address is looked for in the MLS cache. 3) When there is a outgoing standard IP ACL applied to the MLS-RP interface, a Source-Destination IP flow mask needs to be used. This forces the MLS-SE to look for an entry with both the source and destination IP addresses in the MLS cache. Here's the reason why: If a packet has been sent from the MLS-SE to the MLS-RP, the packet gets routed, then the outgoing ACL is applied. If the packet makes it back to the MLS-SE, then the MLS-SE knows that the packet was allowed (not denied by the ACL) and it makes a MLS cache entry. Since a standard IP ACL uses source IP to permit/deny, the MLS-SE needs to look for the source IP as well as the destination IP in the MLS cache. Any subsequent packets from/to

My apologies, I said CBWFQ when I meant LLQ (I have been using them synonymously since LLQ was built off CBWFQ). LLQ is the way to go.

I mean LLQ is basically PQ-CBWFQ, and offers a CBR priority queue for the voice to use. With CBWFQ your voice traffic is going to be weighted based on class, just like other traffic, and even in a best case scenerio could still get some packet trains causing unpredicatable latency..or are you recommending CBWFQ solely based on bugs in LLQ?

BGP for 2 T1's to one LAN [7:7511]
We are trying to have the web servers in our LAN accessible to the internet via 2 T1's from different providers -- more for redundancy than load sharing, though that matters too. Currently we have 2 T1's, each giving us a different set of IP addresses. That just lets us put some sites on each T1 -- doesn't give us an ounce of redundancy. I've been told that if we get a router with 2 WIC's that can speak BGP (Cisco 2600 or better) that may solve our problem. I'm very new to routing, so can someone answer some basic questions? Is the idea with this solution that we will be running just one set of IP addresses?

My CPU started climbing back into the 30% range and when I did a show run the router had automatically added no ip route-cache cef and no ip route-cache as if they were two separate things. I wasn't able to get it to fast-switch without the route-cache command and I couldn't get it to take ip route-cache cef without also removing the regular no ip route-cache command. I never did get true packet-by-packet load balancing across the 3 T1s. It seemed like turning off route-caching turned off CEF for that interface and it went back to process switching. But, with it turned on the load was spread across the 3 T1s, but not equally. I'll probably have to ask our Cisco SE why the 'load-balance per-packet' doesn't seem to be working like we would expect it to. -Original Message- From: Mike Fountain [mailto:[EMAIL PROTECTED]] Sent: Wednesday, June 06, 2001 4:17 PM To: [EMAIL PROTECTED] Subject: Re: CEF/dCEF [7:7330] No, it isn't exactly packet by packet. Supposedly you can get packet by packet, but I haven't yet. After turning CEF we configured the interfaces for ip route-cache cef and ip load-balancing packet-per-packet There are 3 T1s on that guy, and last time a looked the loads were 2/255, 5/255, and 8/255. I'm thinking maybe if we used the load balancing command with no ip route-cache instead of the route-cache cef command it might be a little more even. This is a new turn-up so we're still playing.

RE: Dos Attack [7:7049]
In my experience, no. I've turned on IP accounting on routers doing hundreds of megabits of traffic with no noticable effects. Course, there are always the potential for bugs/instabilities in the code, but barring this I think you should be fine. Just watch the CPU via sh proc cpu before and immediately after turning on IP accounting. If you start seeing the CPU spike very high you can always disable the accounting.

RE: BGP for 2 T1's to one LAN [7:7511]
I'll take a stab at some of this ... First - If I recall, and I may very well be wrong here, I though DNS round-robin was solely for load-sharing, not redundancy. Second - Regarding BGP multi-homing ... some gotchya's that we ran into: You will need an ASN Some ISP's have netblocks designated as re-routable, if your netblock isn't one of them they will make you re-address . Some ISP's require a /24 netblock to be used for BGP routing Some ISP's require that you also register your maintainer object with RADB Routers must have 64mb RAM for partial/default routes and be BGP capable Also, since you are doing this for fault-tolerance reasons, I would also recommend using: two separate routers ... each with 1 WIC and 2 FastEthernet interfaces the WIC -- ISP Fast 0/0 -- your LAN , running HSRP Fast 0/1 -- other router ... this will be for iBGP And you could then multi-home each of your servers to each of the switches and use NIC teaming for redundancy there In this case - all of your outbound traffic will use the ISP connected to the router with the active HSRP address, while all inbound traffic will come in via the ISP with the lowest BGP 'cost' from the source ... not balancing, but load sharing . I am probably forgetting something here, but the idea is to have no single point of failure :) Thanks!

RE: BGP for 2 T1's to one LAN [7:7511]
Since you're running an e-commerce site then users probably establish sessions which are dynamic in nature, passwords, logins etc. If you need failover capabilities you need to consider that if a failover did occur, you'd want active, open sessions statefully failed over to the backup server. I'd be pretty pissed if I was in the midst of a high dollar transaction and my session died on me. Things could get pretty complicated there. The only way I know of achieving that sort of capability is by doing clustering. Since your application is already installed and running, then a cluster solution is more difficult to engineer.

RE: Layer3 switch vs Router [7:7406]
My point entirely. In the old world, a device that concerned itself with the IP address was a router, and a device that dealt with the MAC address ( yes I know this is not exactly true, in that routers do have to deal with MAC's.) A router's job is path determination and packet forwarding based on that determination. In the old world, a switch is really a multiport bridge. In the new world, speed is the driving factor, and the designers use every trick they can to increase speed. These innovations are not limited to layer two or layer three. In fact, it is good to recall that in reality there is no such thing as layer two or layer three. Devices operate on a bitstream, use offsets to determine where the information is that they need to proceed, use buffers and caches and specialized architecture to accomplish what they need to accomplish, and faster than ever. I'm willing to bet, though, that when you got into the discussion at the EE level ( something I am totally not qualified to do ) that you would find where the real distinction are, if there are any. I know I am not the only one who has attempted to wade through the white papers and walk away thinking I've just bought a bridge ( so to speak ) Chuck -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]] On Behalf Of Michael L.

If you look at the name on the Cisco 12000 you'll see it's called a GSR = Gigabit Switch-Router. At this point, even Cisco realizes that it's incorrect to call it simply a router because anymore the combinations of switches and routers have been combined. The real funny thing is, out of all of the units you listed, Cisco only calls one of them a (plain) router, the 7600. The others are refered to as either a switch-router or a multilayer switch. So, you'll notice the only router listed here can do 30 million PPS, while the two high end switches can do almost 6 times (170 mPPS) and then over 12 times (over an order of magnitude more) than the actual router... so thank you for proving my point. =) Having said all that, my whole point is multilayer switching integrates the best of routing and switching to provide better performance.. and I think my point has been proven.

YMMV, VWPBL, TOSTCAAT. And this only addresses redundancy near the top of the OSI model. You are also looking to make redundancy happen at the bottom, and that's why you have two T-1s, and you've gotten some good answers on that. And if it's so bloody important, you probably will be wanting to put in some redundancy at the server as well, perhaps Win2K Network Load Balancing or something from the *nix world. And remember, always ask 'What happens if Mars explodes?' TTFN, Bill in Anchorage -Original Message- If the ISP dies then, yes you'll lose both sites, but the world is a single point of failure.

IP Forwarding to Cisco [7:7555]
Hello Group, I'm currently trying for a temporary solution to get my network up and running. Basically all the telcos are late with the WAN links, so I'm trying to make use of dialup in order to configure servers in the network. The setup I'm trying to achieve is by using a computer to dial out and forwarding all traffic to a Cisco router connected to it. Reason for this is that ISPs use dynamically allocated IP addresses, and dialer interfaces require IP address hard coded into the config. This would not work, hence requiring the intermediate computer to dial out for me, since that would accept dynamic IP address allocated, and the LAN interface to the Cisco router has a static IP. I've tried NAT, and that works fine except I'm also trying to get a GRE tunnel through. It seems like GRE tunnel doesn't like to go through the NAT. So I'm looking for other suggestions.

Re: Bridging one subnet and routing another over the same [7:7567]
Your network may require you to bridge local traffic within several segments while having hosts on the bridged segments reach the hosts or routers on routed networks. For example, if you are migrating bridged topologies into routed topologies, you may want to start by connecting some of the bridged segments to the routed networks. Using the integrated routing and bridging (IRB) feature, you can route a given protocol between routed interfaces and bridge groups within a single switch router. Specifically, local or unroutable traffic will be bridged among the bridged interfaces in the same bridge group, while routable traffic will be routed to other routed interfaces or bridge groups. Because bridging is in the data-link layer (Layer 2) and routing is in the network layer (Layer 3), they have different protocol configuration models. With IP, for example, bridge group interfaces belong to the same network and have a collective IP network address. In contrast, each routed interface represents a distinct network and has its own IP network address. Integrated routing and bridging uses the concept of a Bridge Group Virtual Interface (BVI) to enable these interfaces to exchange packets for a given protocol. A BVI is a virtual interface within the switch router that acts like a normal routed interface. A BVI does not support bridging, but it actually represents the corresponding bridge group to routed interfaces within the switch router. The interface number is the link between the BVI and the bridge group. I hope this helps, for furhter information check this link: http://www.cisco.com/univercd/cc/td/doc/product/l3sw/4908g_l3/ios_12/7w515d/config/bridging.htm#xtocid176215 From: Chris Fortune Reply-To: Chris Fortune To: [EMAIL PROTECTED] Subject: Bridging one subnet and routing another over the same interface [7:7481] Date: Wed, 6 Jun 2001 23:42:47 -0400 I have a situation where I have two 2600 router - one serial and one ethernet port each, connected together by a T1 point-to-point link that is doing bridging only today.

Re: BGP for 2 T1's to one LAN [7:7511]
If the ISP dies then, yes you'll lose both sites, but the world is a single point of failure. Unfortunately, all the ISP's we've worked with are much more likely to fail than the world is or the Internet at large is. Both ISP's we have now (names withheld to protect the guilty) have bad habits of messing up their routing tables and cutting us off. We will do a trace from the outside and find to routers looking at each other. Makes for comical traceroutes, but doesn't keep e-commerce running. With one ISP we have to wade through support personel who think that bringing us cell phones will be a temporary solution before we finally (maybe) talk to someone who knows a router from a microwave oven. The other ISP will tell us we can't telnet to your router. Go power-cycle it call back. Or they'll say, we are connected to your router. Are you sure there's a problem?

Re: How to create VLANS [7:7495]
It looks like you'll have the following topology: 2501 fa# -ISL trunking--fa2/1 2924 You'll need to trunk the connection since you will be using the 2501 to do the intervlan routing (I have to check if the 2501 will support trunking though, maybe someone in the alias knows). You'll also need to trunk the faste interface of the 2924xl, which is as follows: 2924xl#conf t 2924xl(config)# 2924xl(config)# int fa0/1 2924xl(config-int)#switchport trunk encap isl 2924xl(config-int)#switchport mode trunk Also, the 2924xl refers to the interface, not ports. So, to assign the vlans to each interface you'll do the following: 2924xl(config)# inter fa 0/1 (if you mean fa2/1) 2924xl(config-int)# switchport mode access 2924xl(config-int)# switch access vlan 1 and so on and so forth for the rest of the interfaces. The above config will not show up int the running config since the 2924's interface are defaulted to vlan 1. To check the rest of the config do show inter fa#/# switchport. It'll tell you what vlan the interface is assigned to. I hope this helps.

Re: help on Nlsp [7:7580]
First, you dont need ipxwan to connect two routers together, you only need it if you need to talk to a Novell server on the other end of a WAN link (as in that server is also routing). You can just use 'ipx network #' (no encapsulation to worry about) on those links. Second, when connecting two routers with ipxwan you dont need 'ipx nlsp enable' on the interface. If you are connecting to a Novell box the necessity of that command depends on the Novell configuration. Third, try 'ipx ipxwan 0 unnumbered 'routername'' instead of specifying the local node and network number. The '0' above designates to use the global local node id. Im pretty sure this refers to your internal ipx network and since you have one internal you would be safe using this. I would recommend unnumbered as really that is what ipxwan was designed for (between two Novell boxes there is no ipx network number).

RE: 2522 Ints Up\Down [7:7548]
My guess is that there is a hardware problem. All those top interfaces most likely sit on a daughter card which plugs into the main board. you might want to open the router and reseat the card. There are also contact cleaners like Stabilant 22 that can bring bad connectors back to life. -Original Message- From: Sean C.

The 2522 has 10 serial interfaces - 2 sync and 8 sync/async. The 2 sync interfaces (Serial ints 0 1) and the first two of the sync/aync int (Serial ints 2 3) are on the bottom row of the router and Serial sync/async ints 4-9 are on the top row (I include this for people who didn't know). My problem is I can't get Up and Up for any of the top row of sync/async Serial interfaces - it's only UP and Down!?! Where's my line protocol problem? I'm connecting to a 2501. The 2501's config is this: interface Serial0 ip address 192.168.1.150 255.255.255.0 no fair-queue clockrate 64000 ! ! router rip version 2 network 192.168.1.0 !

If I take the IP address (or any other IP add scheme) off of int Ser1 of the 2522 (or Ser 0, 2 or 3) and apply it to Ser's 4-9, the router is only UP and DOWN. It's like the whole top row of the 2522 will not turn Up and Up. On the other hand, when I use the exact same configs on Serial ints 0-3 I get Up and Up. What am I missing? Switched cables, played with different IP schemes, different routing protocols, connected to different routers rather than the 2501, switched DCE/DTE connections, bumped the routers a few times, checked CCO - nuttin'!!!

RE: CCIE written. .books? [7:7584]
To throw in a couple of cents on this topic, my recollection is that the CCIE written was in many ways similar to the CID exam, but with the added emphasis on token ring and RIF's. My own recommendation would be to use your CID materials for the desktop stuff, download the white papers found on Cccert and groupstudy, and thoroughly review how data moves through a network. Certification zone is a worthwhile investment. Excellent white papers ( disclosure - I have been compensated by cert zone for certain work done ) even though it is filled with errors, the exam cram book by Thomas and associates contains the rest of what you need. I was surprised to find that the CCIE written was far easier than I expected. Having gone through the CCNx tracks alleviated much of the difficulty of the exam. Fair warning - the Lab will get you. Having passed the written in no way qualifies you or prepares you for the actual Lab exam. I call the written base camp and the Lab Everest the analogy is about right. You are two thirds there in height, but that last third is 10 times harder than the first 2/3's, and your working without oxygen most of the way.

Re: CCIE written. .books? [7:7584]
Anthony - one of my study partners has loaned me the CCIE 350-001: Routing and Switching Prep Kit ISBN 078972359X. It has been very hepful and it also has the entire book on CD (if you carry your laptop around all the time, that's a real bonus). Additionally, it has Flash Notes and a Test Engine with 240 questions and answers. Also, there is an Objectives Index that comes right from the CCIE RS Blueprint to help you assess your knowledge of the subjects. If your background is good, this book will present the information that you need to pass the test, and also give you places to jump off if you need to do more research on a subject (for example, my weaknesses are BGP, security TACACS and RADIUS, and multimedia) you can do your research on the web or using the 9 books that you have referenced.

State of the Art on MPLS !!! [7:7597]
Hi All, I am trying to understand the state of the art on MPLS technology. Does anybody know if either CISCO or Juniper supports MPLS label stacking, label merging, explicit label assignment on explicit routes. Also, what are the necessary hardware and software requirements for them. Thanks in advance. Krishnan.

it might be one of these 2 things: you are trying to telnet into the outside interface, which is not possible or you have a freaky version of software (5.2.1 or something) that you cannot telnet to at all after the initial boot. after the reload it starts working fine Dragi Message Posted at: http://www.groupstudy.com/form/read.php?f=7i=7601t=7542 -- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
Re: Layer3 switch vs Router [7:7406]
I am testing MLS on a cat5500 and have not been able to demonstrate any throughput improvement using FTP as a test application. The cat5500 has SupIII (4.5.12), RSM (12.0.7T) with NFFCII and 3 24port 10/100 ethernet line cards. I have 7 Vlans configured and the mls settings on both the RSM and SupIII. When FTP is run inter VLAN the throughput is same whether I have MLS enabled or not on the SupIII card. When MLS is enabled I have verified functionality using the various show mls commands so I am sure its working I just don't see any throughput improvement. Is this a function of ftp client and server performance (using laptops with 10/100 ethernet cards on NT)? Should I use a different application or unix client / server to test throughput? If someone has any information I would appreciate your experience. Denton, Jason wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]...

Re: How to create VLANS [7:7495]
Iyuri, You need a 100Mb ethernet port to do trunking, which the 2501 doesn't have. A 2600 series will though. If you don't use trunking, then you will need a 10Mb ethernet port on the router for each VLAN you want to route between. In this instance you're just setting up standard access links that carry only a single VLAN rather than trunk links that can carry multiple VLANs. Here's a bare bones with 2 VLANs and trunking using a 2621 router. 2621: interface FastEthernet0/0 no ip address no ip directed-broadcast speed 100 full-duplex ! interface FastEthernet0/0.1 description Management encapsulation dot1Q 1 ip address 10.1.0.1 255.255.255.0 ip helper-address 10.101.1.1 no ip directed-broadcast ! interface FastEthernet0/0.2 description Corporate encapsulation dot1Q 101 ip address 10.101.0.1 255.255.255.0 no ip directed-broadcast 2924XL: interface FastEthernet0/1 switchport access vlan 1 switchport trunk encapsulation dot1q switchport mode trunk ! interface FastEthernet0/2 switchport access vlan 101 spanning-tree portfast ! interface VLAN1 ip address 10.1.0.21 255.255.255.0 no ip directed-broadcast no ip route-cache ! ip default-gateway 10.10.0.1 Hope this helps, let me know if you have any questions Karen *** REPLY SEPARATOR *** On 6/7/2001 at 4:48 AM Iyuri Yagami wrote: Hello Everybody.

Re: ipsec question [7:7568]
Dar, Cisco allows you to encapsulate gre tunnel traffic in IPSec. Cool huh? So actually you can encapsulate almost any protocol traffic in IPSec. Tunnel a tunnel. Read this: http://www.cisco.com/univercd/cc/td/doc/product/software/ios113ed/113t/113t_3/ipsec.pdf It's really good I read it 3 times -Page 6 notes the supported encapsulations reading: Supported Encapsulation IPSec works with the following serial encapsulations: High-Level Data-Links Control (HDLC), Point-to-Point Protocol (PPP), and Frame Relay. IPSec also works with the GRE and IPinIP Layer 3 tunneling protocols; however, multipoint tunnels are not supported. Other Layer 3 tunneling protocols (DLSw, SRB, etc.) are currently not supported for use with IPSec. Since the IPSec Working Group has not yet addressed the issue of group key distribution, IPSec currently cannot be used to protect group traffic (such as broadcast or multicast traffic).

Re: Layer3 switch vs Router [7:7406]
How 'bout $.03? If you look at the newest Cisco announcements, its clear that the GSR and 6500 technology will replace the legacy 75xx and other high-end router platforms. These systems, depending on firmware, will use hardware based CEF, which will negate the MLS flow establishment process. In addition, with the FlexWAN technology, Cisco is trying to steer a course that places the 6500 and 7600 (a 6500 on its side) in distribution and core layer WAN, with the GSR serving IP backbone/transit. = Robert Padjen __ Do You Yahoo!?

Re: CCIE written. .books? [7:7584]
Hi Anthony, I second the opinions found here.I'm cutting and pasting a posting I did on the networkstudyguide.com website after I passed the CCIE written at the end of April. I hope this helps - it's not a 'single' source but gives you a good foundation... Alright, enough with all the pleasantries, just wanted to give everyone a heads-up on how I conquered the written (now on to the true beast - the lab - gulp!) Like has been written before, the CCIE written isn't too much harder than the CCNP questions - just the breadth of the subjects is so much more diverse. I was actually quite shocked at my test - after reading all those posts about RIF's and token-this and bridge/ring-that and canonical addresses - I was expecting a large percentage of the test to be devoted to those areas which I never-ever use. Well guess what - I think that I had maybe 6 questions on tokens and bridges - no RIF's, no canonical addresses - I want to write What a waste! but can't feel guilty after knowing more than before. I want to list all my sources that I used in preparation for the test so everyone can see how I prepared. In order of relevance to the test my studies included: 1) CCDP - cornerstone of Cisco cert. logic. You're almost there when this is done. 2) CCNP - questions are similar in testing ability. Just the amount of material is more daunting. 3) BSCN class - took the class a week ago even though I had my NP knocked out in November. Class very relevant to the CCIE written - probably 40% of the written I knew from that class alone. 4) Boson tests 1 and 2 by Bernard O. Kept a tally going during the CCIE written - over 40 questions on the CCIE written also in the Boson tests (or very similar). Can't say enough about them. 5) CCIE notes from sitamoht.com. Started reading the notes a few days ago and found them extremely relevant and hit some topics in a different light. http://sitamoht.com/cciewe.html 6) Lou Rossi's token ring paper from CCPrep.com. Yeah, yeah, I know, I wrote that I didn't have that many token questions but this is the paper that made me prepared for whatever they threw . http://www.ccprep.com/resources/news/archives/Token_Ring2.pdf 7) RIF generator from Chad Dixon (member of this site). Again, I know that RIF wasn't big on my test but Chad's cool little site helped get the RIFs down cold. Thanks Chad! http://www.loopy.org/rif.cgi 8) Newserver from Groupstudy.com - groupstudy.com's newsgroup rocks, it's free, and it's very busy. And with help from sources such as L. Oppenheimer (Top Down Network Design - CiscoPress), H. Berkowitz (various BGP papers and books), John Swartz (co-wrote Sybex's CCIE study guide with Lammle) you can't go wrong. 9) Archives from Groupstudy.com. Thousands of posts from people that have had questions just like us - search and your questions will be answered! http://www.groupstudy.com/cgi-bin/wilma/cisco 10) This site with posts from Egraus and lpgao. - search hard. from networkstudyguide.com, not groupstudy stuff. 11) Lammle's Sybex CCIE Study guide - good if you can only carry around one book for the CCIE - not enough though but gets your feet wet. 12) Caslow's routing book - we've all seen the reviews - a must for the lab and a great review for written. Will admit - Boson's tests (ie - Bernard's tests) references the Caslow book an awful lot for questions. 13) Google's site - used to be Deja's site. Not as active as it used to be but still a great studying spot. http://groups.google.com/groups?oi=djqas_ugroup=alt.certification.cisco 14) I bought a subscription to CertZone. Before the test I thought it was a great site. After taking the test, I now look back and think I could have utizlized my time better elsewhere. The tests they have are much more difficult than the CCIE written. Can't blame someone though for trying to make one smarter. They're docs are great and I plan to use them for the labs. Good luck Anthony, Sean C. PS - if you need to find me - I'll be at the lab alter preparing to be sacrificed!!

[7:7259] CCIE start buying books immediately !!! I finished the CCNP a few months back, but have been working on the lab (using CCIE boot camps) for a little over a year now. I would say the next step is to take a deep breath hit www.bestbooksbuys.com. I'm @ about $500 for the month. If you are looking for some recommendations (I have a lot of CCIE coworkers/ mentors) contact me offline. I know Louie, Chuck, Howard have built quite a list also. Phil Hi Phil. My name is Luis. I could use some recommedations from you Howard, Chuck, Thanks. Luis.

Re: Weird Scenario question [7:7590]
Yes, Sorry Bob, 4 port IMA card is the plan. Should have laid out that the routers were 7200 Series. I have checked out the information. Maybe I am missing something. But it still looks like I have the same result just different architecture. Please tell me if I am missing something here. Advice welcome.

Both routers are running CEF. And both are configured to run Load BalancingPer Packet. So packets are being distributed evenly across 3 T-1s on each side. Ok so now I am doing this at Layer 2. Customer currently had an idea put in their head about IMA (Inverse Multiplexing). Well withIMA I will be taking 3 T-1s and making them look like one giant pipe, but it will fragment/Segment/chopup whatever you want to call it the traffic and ship the data across all 3 physical pipes in a round- robinfashion. This is done at the SAR level, if I am not mistaken. Layer 2 again, Right? What is the benefit to traffic? Latency/Delay improvement? Still have inherent delays of T-1s. Anyone got any feedback or ideas? Am I in left field.
