CCNA 2.0 questions
hello everybody I want to take CCNA 2.0 exam soon but I don't know if I have study enough... I only read CCNA Certification Guide for version 1 from Cisco Press. And I also did some practice exams from Boson Software... Are those materials good enough to pass CCNA 2.0 ? In particular, does the exam contain any OSPF, EIGRP and ATM questions ? And what sort of subject should I focus on for the exam ? Thank you in advance for the help...

Re: Multilayer Switching vs. External Router
Hello to all, I would like to clarify some of the process of MLS using the 6500 chassis. What actually gives you the performance increase is the PFC card that is also installed on the supervisor module along with the MSFC. MLS uses the MLSP protocol. This protocol is the communication layer between the RP in the MLS process and the SE. The RP is the Route Processor and the SE is the Switching Engine. Using the MLSP protocol the RP informs the SE of the MAC Addresses of the L3 interfaces in the chassis. The SE caches this information. The cache it uses is a shared cache that is used by the other processes that can use the MLS process(Multicast and IPX). The cache is configurable. The SE is the PFC with an ASIC for this task. When a packet is at the ingress, the SE logic sees it and being that it is destined for a MAC address that it knows about it keeps L3/L4 info. This is called a candidate packet. After an egress interface decision process(CEF, Fast switching), the packet is put back on the backplane. When the SE sees that the source is from a mac address it knows about, it checks it cache, it will have a match, via the candidate entry. This second packet is called an enabler packet. After the enabler packet the SE ASIC, handles all of the L2 re write information at the much higher speed, taking processor load of off the CPU of the MSFC. It is possible to have the RP located externally from the chassis. A single RP can service multiple SE capable devices. A situation where you may use this is if you have several 6500 using regular CatOS code(say 5.4 or so). The supervisor modules do not have to have the MSFC, but can have the PFC, so they are capable of MLS but they do not contain the necessary RP logic. This is solved via the external router to perform the RP function and to use the MLSP process to inform the SE which resides on the 6500 chassis of the necessary information. Deployment could be a centralized router function witch has an interface in the different respective vlans residing in a particular switch or multiple switches. This allows the non L3 capable switches to use the MLS process.

Re: Router CPU power
>Hello to All, > >What command can I use on a Cisco router to display >the Mhz power of the router? > > >Thanks > >Omer What problem are you trying to solve? Even small routers have some distributed intelligence -- the physical and data link handling are not in the main processor. As you move up in routing power, more and more ASICs and processors are involved in handling an individual packet. Performance can vary significanty with the particular path a packet takes through the router. So the MHz of one processor doesn't necessarily determine router performance. Indeed, I'm not even sure if MHz is a meaningful measurement for some of the ASICs. Perhaps a more hardware-literate person can comment there--they presumably are clocked. Another area, more to the point in very high speed routers, is that the chips are evolving to having multiple data streams and possibly multiple instruction streams. ___ 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]
Re: Multilayer Switching vs. External Router
Mark's clarification at the "higher" end of the spectrum is excellent. Let me add some comments at the "lower" and "highest" ends. In selecting equipment, never look at performance alone. Look at price-performance. I've had any number of situations where putting two or more low-end routers or switches next to one another was more cost-effective than moving to the next higher product family. Now, consider a situation where you make extensive use of VLANs. You have clients in one or more buildings, connected via campus fiber to a server room where most servers are either dedicated to one VLAN, or are VLAN aware. In such a configuration, you only need Layer 2 switching for most servers. Backup traffic passes over a dedicated VLAN to which major servers are connected with a separate NIC. Assume the users have very little or no Internet connectivity requirement. They do need to reach a shared mail server. The largest inter-VLAN requirement, however, is network management, ranging from pinging, to SNMP polling, etc. from the management side, and infrastructure functions from the client side: DHCP, DNS, etc. Given very little inter-VLAN, routed traffic, it might very well be cheaper to connect a free-standing 2600 to a Fast Ethernet port than to use a high-performance "layer 3 switching module". Distributing all layer 3 processing is still related to the points that Mark makes. You are specializing functions in the box that is best matched to the requirements. Indeed, a low-end box with multiple fast Ethernet ports still might be the best choice for a situation where you need lots and lots of 10/100 ports and the switching is primarily among those ports. At the highest end, the 12000 series is optimized for inter-ISP forwarding, and will outperform a 6500 in the environments for which it is designed. Again not optimized for campus applications, things like the 5300/5800/AccessPath and Service Selection Gateway are optimized for other workload patterns. >Hello to all, > I would like to clarify some of the process of MLS using the 6500 >chassis.

Problems to solve, customers to satisfy
There are lots of posts on "how do I do something for my customer/organization," which, as such, are not the focus of this list. I propose we try to get them much more into the spirit of the list. The Cisco design methodology is a good place to start. True, someone with years of design experience knows when to break the rules. Indeed, my recommended basic methodology isn't exactly the Cisco sequence, although very close. I am far more willing to respond to a "how do I do this" query when someone systematically puts out how they have approached the subject, and where they are stuck. Believe me, this will help you learn. Also, it is an art to identify where you are stuck. In my approach, the basic steps are: 1. Define business requirements, security policy, budget, and executive perceptions of what is important. 2. Inventory the applications. Where are the clients and servers? What OS are they running? What do you know about application traffic patterns? Is there a service level agreement? What problems are perceived by the users? If possible, take benchmarks. 3a) Define a naming strategy and assign hosts to it. b) Define an IP addressing strategy, considering physical location, size of broadcast domains, needs for public address space, etc. Do NOT get stuck in allocating class A/B/C spaces; the world, outside the CCNA, is classless. If there is a network in place, take a baseline. c) Consider the layer 2 addressing scheme. Are there any needs for locally administered MAC addresses (e.g., SNA?) Do you know frame DLCIs, ATM NSAPs, etc.? If there are facilities in place, take baselines. d) Decide where you want to route and where you want to layer 2 switch. 4) Select the networking product features you need. Don't limit yourself to router/switch software alone if you have any control over the entire environment; it's often better to do things in application hosts or network management servers than to force everything into a router. 5) Select the hardware and media you will need to support the features and network. It's very likely you will bounce back and forth between steps 4 and 5, trading off hardware and media bandwidth against software. 6) Verify you have coherent migration, management, and benchmarking plans and tools. ___ 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]

I don't agree with that policy, and I don't think it's widespread. But if the basic tests don't show the problem, mailing the postmasters or webmasters at that site, preferably from a different domain, is a good idea. You might not be getting ICMP destination unreachable or administratively prohibited because you are being blocked on a firewall.

Re: DHCP on Router!!

DHCP and subnets
Hello folks, Please clarify this for me. Hypothetical example: Campus LAN with multiple buildings. Each building on its own vlan and with its own subnet addressing scheme. All buildings tied in to a Catalyst 5500 which has RSP doing all the inter-vlan routing. Data center using a single DHCP server with multiple scopes (one scope per vlan/subnet etc) to supply all vlans/subnets with their respective ip addresses. I want to understand how the DHCP server knows how to hand out the correct ip address from the corresponding subnet to the workstations that request them. I have come to believe that initially DHCP servers have no idea whom is requesting an address, they just hand them out to whoever asks...this is what is confusing. I understand that each Vlan needs its own gateway address where the workstations aim their broadcasts and there an ip helper-address statement in the RSP for each vlan, but I still don't understand how the DHCP server knows how to hand out the appropriate address when it has multiple scopes enabled. TIA for any clarification you can offer.

Re: 7204/7204VXR
sort of - you can use them in higher _bandwidth_ densities - you can't physically get any more cards into the chassis. There is a points system whereby cards (7500 PAs without the VIPs basically) are assigned a points value based on high, medium or low bandwidth, and are limited to certain combinations based on their position on the backplane. The VXR and NPE300 options just up-rate the amount of points you can run across the backplane check: http://www.cisco.com/univercd/cc/td/doc/product/core/7206/7206cfig/3471pac6. htm#xtocid3206 HTH Andy - Original Message - Michael Vicchiollo wrote: > Jim, > > See inline > > > -Original Message- > > From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of > > Jim Garron > > Sent: Thursday, July 13, 2000 9:12 AM > > To: [EMAIL PROTECTED] > > Subject: 7204/7204VXR > > > > Can anyone tell me if you can use the cards from a 7204VXR in a 7204. > > Yes, in higher densities.

RE: Windows based sniffer
At 06:45 PM 7/15/00, William E Gragido wrote: >Etherpeek is pretty cool, although I am pretty sure that Sniffer offers more >total functionality. Sniffer has a built-in expert system that analyzes packets and automatically identifies problems. Sniffer also has terrific decodes for almost every protocol known to mankind. Sniffer has been around the longest so the developers have had more time to implement sophisticated and detailed decodes. Network General was late getting into the market for graphical user interface analyzers. They stuck to their DOS-based Sniffer for years. Most people liked that user interface, but it was old-fashioned. Their newer GUI is kind of clunky. EtherPeek was first developed for the Macintosh. It has always had an elegant and intuitive user interface. EtherPeek doesn't have a built-in expert system, but it does have the Plug-In Info column that shows you useful information. AG Group also sells NetSense which is an add-on product that does expert analysis. Other kudos for EtherPeek: you can capture and decode at the same time. (With Sniffer, you have to stop capturing to view the packets.) EtherPeek lets you open multiple capture windows, each with different filters. Although you can easily tie yourself in knots by opening too many capture and display windows, you can also use these features for efficient troubleshooting. Bottom line: EtherPeek is a terrific product, but some of the decodes need work.

Another part of step 1 is accurate determination of top management's FUD factor: fear, uncertainty, and doubt. Often something spread by vendors. It's also worth being aware of top management's attitude toward risk and technology. Some are early adopters who demand technologies before they are ready for prime time.

dhcp on router?
hi! all. I thought that the router only forwards the DHCP request from clients to DHCP server. So, can router dynamically allocate ip addresses for DHCP requesting clients without reaching to DHCP server? Then the router also should have same stack of all ip addresses on its memory.. How does router get all ip addresses? Does it receive from DHCP server? If the router serves ip addresses, what is the benefit of it? Could somebody answer this?

RE: dhcp on router?
A router can serve as a dhcp server. You can set the WINS server, name server, etc. ip dhcp excluded-address 10.10.10.5 ip dhcp excluded-address 10.10.10.6 10.10.10.12 ! ip dhcp pool GROUPSTUDY network 10.10.10.0 255.255.255.0 dns-server 10.10.1.1 10.10.5.2 10.1.1.1 netbios-name-server 10.10.12.2 10.10.20.2 domain-name groupstudy.com default-router 10.10.10.1 lease 0 8 This is a sample configuration. I haven't tried the above configuration, but I think I've got everything. As you can see there are options to set the same options you would with a traditional dhcp server. Regards, Aaron K.

RE: dhcp on router?
The router will act as a DHCP server with little trouble. I think that came out in the 12.0.2 code. If you're comparing it between the router and NT servers then I see little additional benefit either way. Both platforms will allocate the IP's and IP settings with no problems. So really, I guess it would be personal preferencedo you want to mess with an NT server or if the same person does the routers and IP schemes maybe it's easier to keep it all in one place. Neither of these compare to full fledge commercial DHCP servers you can get from Cisco or other companies that have distributed servers, failover and etc...but you're going to pay a premium for all that. Here's an example of one I'm using: ip name-server 172.16.100.29 ip dhcp excluded-address 172.18.0.1 172.18.2.10 ip dhcp pool DHCP1 network 172.18.0.0 255.255.0.0 default-router 172.18.1.1 dns-server 172.18.1.151 172.16.100.29 domain-name yourdomain.com netbios-node-type h-node netbios-name-server 172.18.1.151 lease 3 Daniel -Original Message- From: jeongwoo park [mailto:[EMAIL PROTECTED]] Sent: Sunday, July 16, 2000 5:04 PM To: [EMAIL PROTECTED] Subject: dhcp on router? hi! all.

Re: Connecting to the console port of a Catalyst 1900
If these have been in operation for 3 years, I would guess that they are the "original" Catalyst 1900 switches. These switches used a different pinout on the console port. I don't know the pinouts, but as I recall, they are almost like a null modem cable. I think one wire connects differently than a null modem cable. The newer Catalyst 1900 switches (the "standard" and "enterprise" versions) use the same cable as most of the other cisco equipment (a rollover cable with a db-9 terminal adapter). The "original" model is not able to use this.

Re: Windows based sniffer
Oh please, don't even complain about the W&G analyzers. When you want to decode packets in real time, (not capture/stop/look/hope) you need a W&G. It does multiple realtime decodes on LAN and WAN while you watch. And BTW Network General/Network Ass. never did develop a analyzer for the Windows enviroment. The NG salesmen kept saying that product was coming. The way Network General developed it was to buy Cinco Systems that had a analyzer product called NetXray. And then for some reason NG took out the real time decode window that Netxray had. I have no idea why they did that. I think that Network Ass. got interested in other markets and products and did not pay close attention to the analyzer market, so that made them slow to go to a Windows based product.

Re: CDP not working on subinterface
I've checked the CIR and we're doing fine there, especially since this is a 256k fractional t-1 running at about 1% utilization. Our circuits are not policed, so even if we were above CIR, nothing gets dropped unless the frame relay network became obscenely congested. As I mentioned before, all other PVCs on this major interface work just fine except one other that has the same symptoms. When I first brought up this circuit, I was at the remote site with a laptop in the console port. Where I first did "show cdp n", both neighbors were in the list, but after a minute or two, one of them disappeared and has yet to return. The line itself is functioning correctly, as far as I can tell. We're not seeing any interface errors whatsoever and it's been up for a couple of weeks, now. Perhaps I've found an IOS "feature." We're using 11.2(18). I think I'll check CCO and see if they've noticed this in the past.

RE: DHCP and subnets
My 2c on this . When the DHCP broadcasts crosses the router ,it carries that routers mask and ip info across to the dhcp server ( assuming helpder is there) the DHCP server on seeing that the reqest came from that particular subnet issues an ip from a scope ...U could configure multiple scopes and combine them into one superscope to do this. Hope this helps. Cheers,Padhu -Original Message- From: whatshakin To: [EMAIL PROTECTED] Sent: 7/16/00 12:11 PM Subject: DHCP and subnets Hello folks, Please clarify this for me. Hypothetical example: Campus LAN with multiple buildings. Each building on its own vlan and with its own subnet addressing scheme.

Re: CCIE TEST
Another tip for those of you going onto CCIE, take all the exams below it, i.e. CCNA, CCNP, CCDA, CCDP. This will give you a good foundational knowledge for the CCIE written and lab exams. You will need ALOT more knowledge to pass CCIE, but it will give you a very good start. I found CCDA and CCDP especially useful for the written exam.

Re: Router CPU power
Howeird is completely correct. Sure enough, you can get cpu processor speeds from the gear fact sheet, but this is a poor indicator of how the box is going to perform under load. There are simply too many factors effecting actual throughput to use this metric for anything except a stripped-down router. This is why routers, switches, etc. are rated on PPS. r/ rainman "Howard C.

Re: 2505 routers
1. Yes, the 8 RJ-45 ethernet ports perform the same function as a hub, and act as only a single router interface. 2. A TFTP server does not use logings or passwords, and uses port 69 instead of 21. IIS does not perform TFTP services, but there are many free TFTP servers available on the net for NT, including one from cisco's web site.

did I find a BGP bug?
I am running a 7206VXR for our main BGP box. We're colocated with Level 3 (AS3356) and we have ethernet to them. We have T1s to UUNet (AS701) and Teleglobe (AS6453). I am running OSPF for my IGP and everything seems to be working well there. I have a 7120 in my office that I am using for BGP experiments. Besides what I show below it has a static route 0.0.0.0/0 to the outside world. When I run this config on the 7120 without the filter-list 2 I get a full BGP table viewable via 'show ip bgp' and the routing table gets populated with a bunch of BGP routes. When I turn on that filter-list and do a clear ip bgp from the 7206 and the 7120 I see the message counter going up on the 7120 in 'show ip bgp neighbor' but the BGP table never has anything in it. I chose to filter 3356 since the majority of the entries in the BGP table on the 7206 come from there. It was my plan to trim the BGP entries coming to an internal router down to the point where I could use something smaller/slower (like a 2611 with 64 meg) for BGP experiments and put the 7120 back to work. The 7120 is a bit warped, however, take a look at this evil 'show ver' ROM: System Bootstrap, Version 12.0(5r)XE, RELEASE SOFTWARE (fc1) BOOTFLASH: EGR Software (C7100-P-M), Experimental Version 12.0(2110:181554) [otroan-thanksgiving-rel 196] This is an IPv6 image based on 12.0.

Re: 2505 routers
They're just hub ports, with an internal controller BUT, if you want to pass traffic to another segment or if you want to employ other "routing" functions, i.e. ACL's, Policy Routing destinations, caching tweaks, etc. then the hub connected devices are the segment/broadcast domain those routing functions would target. In other words, you're routing TO the devices connected to the hub through the E0 virtual interface. FTP is one of the TCP/IP applications and TFTP is another =8^) c'mon mister mcse, you knew that! you're testing us, right? =8^) but seriously, if you want the NT box to run the TFTP daemon (listening service) all you need to do is put one on there and configure it.

Fw: DHCP, and, subnets
The RSM work as the BOOTP Relay agent this is what happen when the client request for IP Address : 1 The request packet arrive to the interface (of the catalyst and RSM check this packet). As a note the DHCP request contain the Router Relay IP Address field in the packet). The client use UDP packet port 67. 2. The RSM will replace the Router Relay IP addess field in the packet with the ip address of the interface VLAN configured in the RSM.This will be usefull because the BOOTP server will use this address to relay its replay back toward the client via the relay agent, int this case is the RSM. 3. The RSM send the unicast packet from the Client request packet and send it to the Configured Helper Address. 4. When the BOOTP Server receive the request packet, the server will reply by using port 67 at the ip address that has been filled into the Relay router IP Address field by the relay agent. 5. The RSM ( as the relay agent ) then deliver the response to the client - using either broadcast or hardware Client Address.

[Off Topic] Denials of Service
For those interested in networking Denial of Service attacks whether its to refresh your knowledge or perhaps learn about different types of attacks (some theorized) please stop by and read Theories in DoS. (http://www.antioffline.com/TID/) This is a document in which I have spent some down time detailing ways Denials of Services occur and I have also included sample source code (some broken to deter script kiddies) in hopes I could gather enough data to prevent Denials of Service on my own network as well as assist others in assessing their networks. BGP4, OSPF, RIP, EIGRP, IGRP, IS-IS, ICMP are covered and or under construction. I am very well aware of the implications some may take by thinking of documents such as this and there were some codes and sample packet data which I removed and edited in order to prevent some irrated netizen from causing chaos on a network. I do not intend any malice with the document. Currently I am studying for the CCIE since the CCNA is being changed this year and hopefully I can attain it (CCIE) in about 1 1/2 years or so (who knows) besides I work too long as it is and study time is limited (hey!$!

Recertification Information
Someone else mentioned it earlier, but I am seeing more information on the Galton site implying the term of certification, and by implication, the time of re-certification. If I read correctly, the term of certification for CCNA, CCDA, and CCNP is three years. For example, my completion date for the CCNA was August 5, 1999, and the expiration date is August 5, 2002 ( I actually passed the test on July 13, but I did not get al the paperwork completed until later ) Interestingly, the specializations appear to be valid for only two years. For example, I completed my CCNP/Security on April 7, 2000 and the certification expires on April 7, 2002 I presume Cisco will be making more announcements regarding this as time goes by.

Now, i just implement priority-list command and define priority-group on the interface which running on SDLC traffic but...its not work. The equipment still not work. Here I Send the configuration source-bridge ring-group 310 dlsw local-peer peer-id 10.100.101.1 dlsw remote-peer 0 tcp x.x.x.x dlsw remote-peer 0 tcp y.y.y.y ! interface Serial0/0 description ===> Leased Line to JAKARTA 64 Kbps ip address 10.10.5.5 255.255.255.252 no ip mroute-cache no fair-queue ! interface Serial0/1 description ==> Local DLSw connection to S121440 & 4F no ip address encapsulation sdlc bandwidth 19200 no keepalive priority-group 1 sdlc role primary sdlc vmac 4000.6492.c100 sdlc address 40 sdlc xid 40 017D0564 sdlc partner 4000.4500. 40 sdlc address 4F sdlc xid 4F 017E0577 sdlc partner 4000.4500. 4F sdlc dlsw 40 4F ! ip route (secure)... Do you have any idea how to make SDLC traffic become first priority or how to make SDLC traffic can use 30% bandwitdh from the total bandwidth Thanks for your help Erwin Novriyanto ___ 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]

One AS and different OSPF process IDs
Hello to All, I am running only OSPF on my autonomous system but I am using a different OSPF process IDs on each router, will the routers still communicate? Please note that I am using only one OSPF process per router Thanks Omer __ Do You Yahoo!? Get Yahoo!

Re: One AS and different OSPF process IDs
yes.. the process id is only used internally by the router to differentiate between different ospf processes running on the same router.. however, having said that.. the router's will not be able to 'communicate' if you mis-configure the router with the wrong networks taking part in ospf :) mark.
