Fw: you American need to think [7:38323]
The words "DROP DEAD" immediately come to mind. Sorry for wasting your bandwidth, but I have to say this. Being rich is good; being smart is good. But if you treat others like sxxt, others will treat you like sxxt too. Think about this: if you are a CCNA and your CCIE co-worker say your "stupid" or "dumb", will you respect him? There are so many knowledgeable and friendly people on this list, but there are some rude and arrogant people too. I agree that Bin Laden is a murderer, an evil, but you American need to think why he only attacks US, not Germany or Russia or Japan or others. Show some respect to others, it won't make you poor. Also remember that there are always someone richer and smarter than you. Over. Dismiss. Jim __ Do You Yahoo!? Yahoo!

Re: TCP/IP and DOD [7:39657]
Having a network made the problem of command language incompatibility less of an issue. A researcher could use the hardware and OS of choice and at least send messages to a different piece of hardware with some other OS. With the right software, one could send messages to users and also execute commands and jobs. There was less need to learn many different command languages. According to Bob Taylor of ARPA, this is the problem he wanted to solve. He was an early victim of the swivel chair approach to IS (having to work with many different terminals). We still have that problem, of course, so obviously networks don't solve everything! (I get the info about Bob Taylor secondhand from the book Where Wizards Stay Up Late. It's possible the author slightly misinterpreted what he said about his goals. The book is fascinating but there are a few cases where someone who actually works in the industry kind of wonders about the details described.) Priscilla At 08:17 PM 3/28/02, Howard C.

There are indeed two types of BPDUs. These include Configuration BPDUs and Topology Change Notification (TCN) BPDUs.

That is just the basic difference between the two, I'm sure that there are others in the group with the ability to get much more granular in detail if needed.

RE: Designated Port/Switch and Root Port?? [7:39811]
I'll try to explain this: Think of a root port as the closest port to the root bridge on a given BRIDGE. Think of a designated port as the closest port to the root bridge on a given SEGMENT. This is the port used by all bridges on a given segment to get to the ROOT. Consider the following basic diagram to explain this further with 1 root bridge, 3 non-root bridges and 3 segments: |ROOT|--segment 1--|A|--segment 2--|B|--segment 3--|C| The root port on bridge A is the closet int to ROOT - the int on the left. The designated port on segment 1 is actually the int on ROOT that's in segment 1. The root port on Bridge B is the closest int to ROOT - the int on the left. The designated port on segment 2 is the closet interface to ROOT in segment 2 - the int on the right side of bridge A. The root port on bridge C is the the closest int to ROOT - the int on the left. The designated port on segment 3 is the port closest to ROOT - the int on the right side of bridge B. So, you wind up with something like a consistent and logical topology: ROOT(DP)--(RP)A(DP)--(RP)B(DP)--(RP)C The real distinction is knowing that a root port is a designation specific to a switch and a designated port is specific to a segment. To show this, we can make the following modification to the above topology: ROOT(DP)--(RP)A(DP)--(RP)B(DP)--(RP)C | |--(RP)D(DP)--(RP)E In this case, there are 2 root ports in segment 2 but there will always be ONLY 1 designated port per segment. This is one of the foundational concepts of STP. Also, the ROOT will never have a root port, all non-root bridges will have ONLY 1 root port (per VLAN) and there will ONLY be 1 designated port per segment (per VLAN). Root ports send BPDUs and designated ports receive BPDUs.

RE: If it's a 2611, you're out of luck [7:39788]
Another bit of good info to know: Traditionally, the 1700 series would not support trunking, either ISL or Dot1Q. That includes both the 1720 and 1750. In these cases, you had to purchase a 2600 with IP Plus, which is an expensive proposition to avoid the necessity of 2 or more E/FE interfaces. I just setup for a client a 1721 router which DOES support both trunking encapsulations and does it with IP only IOS! This is a huge savings over the traditional options for inter-VLAN routing. There are also new 1751 and 1760 models which I believe also support both modes of trunks.

It cannot be trunked with a 261X. You'd need a 262X. If you have to deal with a 2611, your options become much more limited. You could replace the 2611 with a 2620. Or you could get a ethernet module for the 2611. Unfortunately, last time I checked (whish was a couple years ago, given) those ethernet modules came in two models, 1 and 4 port, and cost about $1000 per port. Another option would be to replace the 2611 with a 1750. It's got one fast ethernet port. If this network is as small as it sounds, it'd be a viable option. Oh, and about trunking, the way it works is you define the switch port connected to the router as a trunk. This allows multiple (in your case, all) vlans to use the one port. The router is configured with subinterfaces on the fastethernet port, one for each vlan. The router can then route between these vlans.

The designated port is not just the root ports. 1. Each root port is a designated port 2. Each designated port is not necessarily the root port.

Unrelated question [7:39788]
OK, so at least 3/4 of the response to this question say the exact same thing. Or at least hint at it. (It doesn't make sense to me to take the time to answers someones question and do it with 2 words. "vlans" while correct is not, by itself, an answer.) My point is the redundancy. Do some people not read the upt-teen responses before jumping out with their own? Or do some people access these via some other transport (i.e. e-mail) and so don't see the responses? Or do some people just like seeing their names on a newsgroup? It just doesn't make sense.

RE: If it's a 2611, you're out of luck [7:39788]
I think a lot of the issue is, that in the past it did not work because the 10mb chipset in the older routers did not support the sub-intf and vlan trunking. The newer chipsets may well have the ability to do that and Dave has come across something that is included in the IOS and that is supported in the hardware.

Re: What is bandwidth domain? [7:38887]
Would you agree with this statement? A classroom is not the same as a school. Ah ha. I got you. What about a one-room school? That's the sort of logic that you are using. A network that uses just hubs is like the one-room school. It is a single collision (bandwidth) domain. It is also a single broadcast domain, but that's just because they are living in the dark ages like the one-room school and haven't upgraded to a switched environment. A switch subdivides collision domains. But it does not subdivide broadcast domains. You need a router for that, as you know. An Ethernet collision domain is all devices in a network connected via a single cable or hubs. Every device hears every other device's transmission. If two devices send at the same time, a collision results. These device compete for bandwidth. They are in the same bandwidth domain. These devices are also in the same broadcast domain as each other. In addition, these devices are in the same broadcast domain as all devices in their switched network. Devices on the other side of the switch are not in the same collision (bandwidth) domain as these devices however. They don't hear every transmission. They just hear broadcasts because the switch forwards them. They don't compete for bandwidth. Devices on opposite sides of the switch can transmit at the same time and it's not a collision. I think I said it better with the school analogy. ;-) Priscilla At 08:25 PM 3/27/02, John Green wrote: >but please consider this diagram: > > ---ROUTER > |||| ||| | > ABCD EFG H > >A,B,C,D are hosts in say network 10.10.10.0 /24 >E,F,G,H are hosts in say network 10.10.9.0 /24 > >say Host A sends a broadcast, then it will be heard by >the network on left side and not on right side as >ROUTER will not allow any broadcast through. >and the hosts in network on left are connected to a >HUB and network on right to another separate HUB. > >Now the collision domain and broadcast domain for the >network on left side is same. is it not ? > > >--- Priscilla Oppenheimer wrote: > > At 01:02 PM 3/27/02, John Green wrote: > > >so Broadcast domains and Bandwidth domains are the > > >same ? > > > > Of course not.

ATM and Voice [7:39849]
hello after much research, i can't figure out a way to get cheap voice/ATM combo routers to cut my costs. does anyone have any suggestions as to how i can get ATM AND VoIP in my home lab. i want to purchase everything myself, but at the same time, i want to do so in a way that i can save money in the process. for example, (assuming i have a lightstream switch) if i get a 3600 router with voice and ATM installed, it will be well over $4K for each router with all those interfaces. however, if i combine an MC3810 with voice and a 4000 with ATM, i can cut my costs. but with this latter situation, will i still be able to practice VoATM effectively? i really want to ACCURATELY model a lab after cisco's CCIE lab environment. how can i do this with the voice and ATM components? thanks in advance for your replies. btw, renting telnet access and or going to another lab is not an option for me. thanks, eddie [GroupStudy.com removed an attachment of type image/jpeg which had a name of Notebook.jpg] Message Posted at: http://www.groupstudy.com/form/read.php?f=7&i=39849&t=39849 -- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]

I'm not sure if or where this is documented, but apparently beginning with some variants of 12.1 vlan trunking has been available of the 261x with only the 10 mbs ethernet port. One of my pals discovered this just as he was about to walk into his CCIE lab attempt.

PIX QUIZ - New version [7:39818]
Let me wish you all a Happy Easter with the latest version of my Cisco PIX / IOS Firewall command trainer - PIX QUIZ. It now has 71 questions, and I have added the feature of retaking the test with all or only wrong answered questions. I believe I have found all the bugs after I made some drastic changes to the source code, but I would recommend you to save any unsaved documents, e-mails, etc. before running my program just in case. I would hate for you to loose anything because of my application. As usual, this can be found on my RouterChief site under free software. If you have any problems or questions, please feel free to send me an e-mail. If you believe there's a question where you were right and the program was wrong - please let me know what it was, and why you think it was incorrect.

RE: Router question.. [7:39788]
Set each subnet in a VLAN ex. 172.27.10.X vlan2, 172.27.11.x vlan3, 172.27.12.x vlan4. Then set up a trunking protocol 802.1q or ISL between the router and switch. To do this you create subinterfaces on the router's ethernet for each subnet.

RE: question on cisco lab [7:39683]
I had the same issue and its quite simple. I went for a couple of weeks like this and my friend showed me the trick. i assume you have the ip host setups for each router. lets say you have 6 routers R1,R2,R3,R4,R5,R6. Log onto each one in order. Now Cntrl+shift+6 x to go back to your terminal server. To go to each router now just type 1 instead of R1, 2 instead of R2. The reason is you are going back to your open session not opening another one, that is why the connection fails, it is already opened. Went through the same thing.george gittins wrote: > > Im using a terminal server connected to my routers for my built > cisco lab. > however > everytime that i change the ip address or modify the > configuration i can do > a reverse telnet to the router? i need to plug in a laptop and > modify the > con 0 line again > is there a reason for this.

RE: If it's a 2611, you're out of luck [7:39788]
Incorrect. Only ISL requires FastE, 802.1q works perfectly well on a standard Ethernet port. This was covered in another thread a few days ago. -Kent -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]] Sent: Thursday, March 28, 2002 10:15 AM To: [EMAIL PROTECTED] Subject: If it's a 2611, you're out of luck [7:39788] Vlan trunking requires a fast ethernet connection. It cannot be trunked with a 261X. You'd need a 262X. If you have to deal with a 2611, your options become much more limited. You could replace the 2611 with a 2620. Or you could get a ethernet module for the 2611. Unfortunately, last time I checked (whish was a couple years ago, given) those ethernet modules came in two models, 1 and 4 port, and cost about $1000 per port. Another option would be to replace the 2611 with a 1750. It's got one fast ethernet port. If this network is as small as it sounds, it'd be a viable option. Oh, and about trunking, the way it works is you define the switch port connected to the router as a trunk. This allows multiple (in your case, all) vlans to use the one port. The router is configured with subinterfaces on the fastethernet port, one for each vlan. The router can then route between these vlans.

Re: routing between vlans in 2900 throuh external [7:39762]
I think I'm just getting more confused and I'm sure someone out there knows the definitive answer. In the URL you sent Michael, it says what I had always thought, the same-interface command enables fast switching on the same "IP" interface, i.e. logical interface. Then I went looking and found this URL: http://www.cisco.com/warp/public/105/44.html#Q1 which seems to back up Michael's point. If this were correct then why are you able to turn on/off route-cache on individual p-p subinterfaces? ??? Dave "Lomker, Michael" wrote: > > > interface.

Receiving Duplicate Inbound SMTP Messages (Q295725) http://support.microsoft.com/default.aspx?scid=kb;en-us;Q295725 SMTP The fixup smtp command inspects SMTP session and performs three primary tasks: (i) enforce the seven generic commands; (ii) track SMTP command-response sequence; (iii) generate audit trail. The port number defines the well known service port where the SMTP client initiated to connect to the SMTP server. This port is usually 25. However, a different and non-standard can be specified. Enforce the seven generic commands: The fixup smtp command enforces that only the generic seven RFC821 commands can be used during SMTP envelop exchange. These commands are HELO, RSET, NOOP, QUIT, MAIL, RCPT, and DATA. Track SMTP command-response sequence: Each command and response sequence is tracked for the following anomalous signatures: (1) truncated command; (2) incorrect command termination -- not terminated with carriage return and line feed; (3) invalid character, "|;`<>", embedded in mail address. (4) unexpected transition by the SMTP server. (5) TCP stream editing; (6) command pipelining. Generate audit trail: Audit record 108002 is generated when invalid character embedded in the mail address is replaced.

At least not with Cisco equipment. That would require a layer 4 NAT server. Cisco NAT only operates at layer 3. That means the only thing that Cisco NAT will look at is IP address and port. A layer 4 will actually look at the header information to determine which web server it should go to. One workaround is to assign non-standard port numbers to additional web servers. One web server could use port 80, while another one could use port 8080, for instance. This does make it a little harder to access, but it does work.

Re: Line protocol goes up and down [7:39766]
Hi Maamun, I had a similar problem when setting a network connecting two 2500. The line protocol on a serial interface would continuously go up and down. After little bit of troubleshooting, i finally boiled it down to the fact that the serial port on one of the routers was faulty. So try replacing the router (if its not a production box) or try using another serial interface (if its available) and see if that solves your problem. Good luck, Imran Moin. --- maamun Murangwa wrote: > Hi, > > I'm having a problem with a serial interface line > protocol going up and down every few seconds.

It cannot be trunked with a 261X. You'd need a 262X. If you have to deal with a 2611, your options become much more limited. You could replace the 2611 with a 2620. Or you could get a ethernet module for the 2611. Unfortunately, last time I checked (whish was a couple years ago, given) those ethernet modules came in two models, 1 and 4 port, and cost about $1000 per port. Another option would be to replace the 2611 with a 1750. It's got one fast ethernet port. If this network is as small as it sounds, it'd be a viable option. Oh, and about trunking, the way it works is you define the switch port connected to the router as a trunk. This allows multiple (in your case, all) vlans to use the one port. The router is configured with subinterfaces on the fastethernet port, one for each vlan. The router can then route between these vlans.

RE: Router question.. [7:39788]
ISL or 802.1q trunk is an option if the interface hardware supports it. You configure 3 VLANs on the 2900. Trunk those 3 VLANs up to the 2600 and configure that Ethernet interface for ISL or 802.1q encapsulation with 3 subinterfaces, 1 for each VLAN. Another option also works on just one interfacesecondary IP addresses.

Yes. Is it a 2611 or a 2621 or a 2651? If you have Fast Ethernet you can do ISL trunking or 802.1Q trunking.

RE: I have problem with IP telephony [7:39721]
I have seen problems similar to this, but that was with supervised transfers... I don't have an immediate suggestion, but I'm pretty sure the problem is on the voice gateway. Somehow, the voice gateway isn't registering the fact that the PSTN call hung up. Also, I've never worked with FXO so that might be an issue as well.

In referenec to Jim's answer. [7:39788]
It's a kludge but it would work. What Jim is saying is put 2 logical subnet onto 1 vlan. With a switch, it wouldn't really be that bad. The two logical networks would share broadcast traffic, but that should cause any problems.

I'm not sure I understand the question [7:39752]
If you are asking if you can have one public IP address for two internal web servers, the answer is no. At least not with Cisco equipment. That would require a layer 4 NAT server. Cisco NAT only operates at layer 3. That means the only thing that Cisco NAT will look at is IP address and port. A layer 4 will actually look at the header information to determine which web server it should go to. One workaround is to assign non-standard port numbers to additional web servers. One web server could use port 80, while another one could use port 8080, for instance. This does make it a little harder to access, but it does work.

If it's a 2611, you're out of luck [7:39788]
Vlan trunking requires a fast ethernet connection. It cannot be trunked with a 261X. You'd need a 262X. If you have to deal with a 2611, your options become much more limited. You could replace the 2611 with a 2620. Or you could get a ethernet module for the 2611. Unfortunately, last time I checked (whish was a couple years ago, given) those ethernet modules came in two models, 1 and 4 port, and cost about $1000 per port. Another option would be to replace the 2611 with a 1750. It's got one fast ethernet port. If this network is as small as it sounds, it'd be a viable option. Oh, and about trunking, the way it works is you define the switch port connected to the router as a trunk. This allows multiple (in your case, all) vlans to use the one port. The router is configured with subinterfaces on the fastethernet port, one for each vlan. The router can then route between these vlans.

Re: CCIE written exam study advice. [7:39772]
There are the usual books you must read: Routing TCP/IP by Doyle, Internet Routing Architectures by Halabi, etc. You'll want to go to CCO and read all you can about SRB, RSRB, Token Ring, and DLSw+. Make sure you understand basic SNA and NetBIOS. I also bit the bullet and got a one-year subscription to CertificationZone and that helped immensely. Their practice tests are awesome and I found they were actually much harder than the real exam. If you can take a few of those and get a passing grade each time, that's a good sign that you're probably ready for the real exam. Another suggestion would be to get your CCDP before going for the CCIE. A _lot_ of the material I studied for the CCDA/CCDP exams came up in the CCIE written. This would certainly alter your certification timeline a bit but I found it helpful. HTH, John >>> "Sophie Deller" 3/28/02 9:26:13 AM >>> I have completed CCNP and am currently preparing to study for the CCIE written exam. I would like some suggestions as to where to start my study, what courses are recommended and what books others have found useful.

Re: routing between vlans in 2900 throuh external [7:39762]
Hmm, that's odd since when trunking you subinterface the ethernet and each interface, as far a routing is concerned, is an individual interface. Ip route-cache same interface is generally used when using secondary address on a single interface. But if it works...

Thx for the tip Priscilla. I've tried both, pointing to the server and the broadcast address of the subnet that the server is on, with no luck.
