Re: CCIE question about buffers being used up on router
I'll speculate its like this. On a full t1, 1536 megabits are actually usable out of the 1544 on the circuit. Capital B is the byte symbol, and there are 8 bits in a byte, so 1536 divided by 8=192 Brian On Tue, 10 Oct 2000, whatshakin wrote: > Please explain how you got this: 1.544Mbps = 192KB/sec > > - Original Message - > From: Arun Upadhyay <[EMAIL PROTECTED]> > To: <[EMAIL PROTECTED]> > Sent: Tuesday, October 10, 2000 8:34 PM > Subject: Re: CCIE question about buffers being used up on router > > > > > > Hi Priscilla > >I found the solution. > > > > Here it is: > > 1.544Mbps = 192KB/sec > > Router begins to forward at the rate of 64KB/sec > > means it is tranfering at the rate of 3 packets/sec > > i.e it will take 1/3 sec. or 333 ms to transfer one > > packet. > > > > Now it's getting packets at the rate of 5000 > > packets/sec i.e one packet in every 1/5000 sec. or > > 1000/5000 = .2 ms > > so it will get 500 packets in 500x.2=100 ms > > > > So by the time router will forward first packet in > > 333ms, it's buffer will be full. > > > > Thanks for your help. > > > > > > --- Priscilla Oppenheimer <[EMAIL PROTECTED]> wrote: > > > Oops.

RE: 2500 router password recovery
Sounds like you're suffering from the older HyperTerminal where the break sequence didn't work properly. Get the new version from http://hilgraeve.com/htpe/download.html.

Re: challenge problem
Have you checked for clocking issues between the Router and the DSU? (garbage-in garbage-out) I have seen that issue many times. Check the DSU's config vs a known good config. Are the errors also being seen on the carrier's frame-switch interface? The guys who test the circuit do not ussually have access to that info They just test from their test point to your csu...

Re: CCIE question about buffers being used up on router
Hi Priscilla I found the solution. Here it is: 1.544Mbps = 192KB/sec Router begins to forward at the rate of 64KB/sec means it is tranfering at the rate of 3 packets/sec i.e it will take 1/3 sec. or 333 ms to transfer one packet. Now it's getting packets at the rate of 5000 packets/sec i.e one packet in every 1/5000 sec. or 1000/5000 = .2 ms so it will get 500 packets in 500x.2=100 ms So by the time router will forward first packet in 333ms, it's buffer will be full.

Re: ISL VLANS on a router - bridged?
Interesting question. My thinking is that because they are on 2 different physical interfaces the VLANs / trunks remain seperate unless bridged together. I may be wrong but it's defiantly something to play with and see what happens. --- Jay Hennigan <[EMAIL PROTECTED]> wrote: > On a switch, if a unique VLAN ID appears on more > than one trunked > interface, that VLAN is part of the same layer 2 > network and broadcast > domain across all interfaces where it appears, based > on the VLAN number. > > Is this also true on a router?

2500 router password recovery
I'm working with a used 2514 router with an unknown enable password. I've tried the standard break technique but can't abort the boot sequence. I believe that break may be disabled. I'm using Win NT 4 and hyperterminal to connect to the console port and am able to connect and SHOW VERSION. I am getting terminal feedback. I've used CTRL-BREAK AND CTRL-SHFT-6 to no avail. How can I access ROMMON mode and change the password? Is there a jumper on the system board that can be used to circumvent the password and access the router for configuration? Any advice is appreciated, Thanks

Revisit of Out of Office reply problem
Hi everyone, I finally got the precedence: bulk header installed on the e-mail messages for this group. This header, according to some suggestions, may stop Out of Office replies. So, let's keep our fingers crossed. Two messages I sent tonight only generated one Out of Office reply -- so it may be working to limit the problem. Of course I am wondering how many people out there have software that blocks precedence:bulk messages as being from spammers. Keep me posted! Paul Borghese **NOTE: New CCNA/CCDA List has been formed.

If you convert that to bits it's 512 bits. 5000 packets of that size per second is 560,000 bits per second, which is a lot less than 1.544 Mbps so not much buffereing will be needed at all.

If you are trying to get help with questions like this that appear on the CCIE written test and practice exams, you will want to give us an example of where the WAN link is oversubscribed. For example, if the offered load to the WAN link is 110% more than the WAN link could handle, 500 buffers would get used up in about 5000 packet times. (I think? Comments anyone?) In reality, packets don't arrive at a constant rate, so much more difficult math and queuing theory is required, and that goes beyond the research and thinking I'm willing to do right now. &;-) Priscilla > Thanks. > > Arun > >= >Arun Upadhyay >SE Engineering >MCSE CCNA CNA > >__ >Do You Yahoo!? >Get Yahoo!

Re: Password encryption decoder
Actually you have it backwards. The type 5 passwords are derived from a one-way hash function using the MD5 hashing algorithm. The router takes the password you give and run the password through the same algorithm. If the hash value matches what is in the configuration, the password is accepted. The algorithm is sufficiently complicated that even knowing the hashed value, it would be computationally hard (but not impossible) to generate a password that would create the value. But a corollary to all of this is that the Cisco router does not "know" the original password! So this encryption scheme can not be used where the Cisco Router needs to present the original password (such as when the router initiates an ISND call using chap authentication.) The other two types of encryption are type 0 and type 7. Type 0 is no encryption and the password is stored using plain-text in the configuration. Someone looking over the configuration will quickly learn the password. Type 7 is only moderately better as the password is XOR against a constant. So the hacker would need run the same computation to derive the password. Ok so what about the enable password and enable secret. Originally we only had the enable password that was using the type 7 encryption. This password could be quickly compromised by dumpster divers that know the constant value (not very hard to find). Therefore, Cisco came up with the new format using the MD5 hashing algorithm. This new password was called "enable secret" to keep the "enable password" available in the configuration for backwards compatibility. If both are maintained in a configuration, the enable secret is used and enable password is ignored. Only if the router is using a version of the IOS (now very old) that does not understand the enable secret will the enable password be used. This is also why when you run the interactive setup command the program complains if you use the same password for enable secret and enable password. Using the same password for both allows dumpster divers to gain access to your router. Hope this helps!

RE: Password encryption decoder
I beleive the enable password encryption is only 40 bit, so if you can get a copy of the string you should be able to use any standard 40 bit password cracker. Also, if it is a matter of recovering a forgotten password and you have physical access to the router, cisco.com has outlined a procedure to reset the password through ROMMON mode. You'll have to search the website, though.. -Original Message- From: Daniel [mailto:[EMAIL PROTECTED]] Sent: Tuesday, October 10, 2000 1:21 PM To: [EMAIL PROTECTED] Subject: Re: Password encryption decoder The Boson software works great for most password decryption.

I am not sure, but logic seems to dictate that both interfaces belong to the same layer 2 network. The way I am picturing it is like this: In any regular layer 2 switched network, you can have many devices of the same type. You could have many clients or servers, or printers or even routers. So why wouldn't the same hold true for your scenario? Now, when you bring it up to layer 3, you definitly have two distinct subnets working. The differnece would lie in how your end users are configured, ie- Which interface IP do you assign as their default gateway... Sorry for the oversimplification.

Re: 2501 Question, remote access
ML I would set up a modem with access to the console port. The AUX port is good, but what if you damage you configuration? What if you need to break a password? There are security reasons why you may not want to do this, but if you take the necessary precautions, you should be fine. The following links to the Cisco Web site should provide you with all of the information that you need. http://www.cisco.com/warp/public/471/50.html http://www.cisco.com/warp/public/76/9.html I also use a specific MultiTech modem that is designed to be connected to Cisco routers. The proper initialization strings are burned is as default settings. That way, the modem never looses its initialization strings. If it does, the modem is broken, and you replace it with a new one. Here is a great excerpt from one of those links. Console Port Issues There are several advantages to connecting a modem to the console port of a router instead of the AUX port; however, the disadvantages are significant. Advantages of connecting a modem on the console port: a.. Passwords can be recovered remotely. You may still need someone on-site with the router to toggle the power, but aside from that, it's identical to being there with the router. b.. It is a convenient method of attaching a second modem to a router without async ports. This is beneficial if you need to access the router for configuration or management while leaving the AUX port free for dial-on-demand routing (DDR). c.. Some routers (for example, Cisco 1600s) do not have AUX ports. If you want to connect a modem to the router and leave the serial port(s) free for other connections, the console is the only option. Disadvantages of connecting a modem on the console port: a.. The console port does not support RS232 modem control (data set ready/Data Carrier Detect (DSR/DCD), data terminal ready (DTR). Therefore, when the EXEC session terminates (logout), the modem connection will not drop automatically; the user will need to manually disconnect the session. b.. More seriously, if the modem connection should drop, the EXEC session will not automatically reset. This can present a security hole, in that a subsequent call into that modem will be able to access the console without entering a password. The hole can be made smaller by setting a tight exec-timeout on the line. However, if security is important, it is recommended to use a modem that can provide a password prompt. c.. Unlike other async lines, the console port does not support hardware (Clear to Send/Ready to Send (CTS/RTS) flow control. It is recommended to use no flow control. If data overruns are encountered, however, software (XON/XOFF) flow control may be enabled. d.. The console ports on most systems only support speeds of up to 9600 bps. e.. The console port lacks reverse telnet capability. If the modem loses its stored initialization string, the only remedy is to physically disconnect the modem from the router and attach it to another device (such as an AUX port or a PC) to reinitialize. If a modem on an AUX port loses its initialization string, you can use reverse telnet remotely to correct the problem. f.. A console port cannot be used for dial-on-demand routing; it has no corresponding async interface.

BGP full routes
Hi, is there anybody who is using a Cisco 3620 router with 64MB to handle BGP4 with full Internet routing table? I am currently multihoming to two ISPs using two Cisco 3620s and planning to run BGP4 with them. But the maximum DRAM a 3620 can handle is 64MB. There is no way I could upgrade it to be 128MB unless I change to two bigger boxes. But before I do that, I just want to check and see if 64MB is sufficient of handling all the Internet routing table. Thanks very much! -Ya **NOTE: New CCNA/CCDA List has been formed.

Trunk question
I have a question concerning trunk ports. I am about to install two 2924M XL switches with the GBIC modules (both slots are filled). I plan to connect both switches in parallel using the GBICs for redundancy. I also need to connect to a 3640. I assume that both the GBIC interfaces and a port on the switch will be trunk ports? Is this possible? Thanks, Jeff **NOTE: New CCNA/CCDA List has been formed.

ISL VLANS on a router - bridged?
On a switch, if a unique VLAN ID appears on more than one trunked interface, that VLAN is part of the same layer 2 network and broadcast domain across all interfaces where it appears, based on the VLAN number.

Do VLAN 2 on switches connected to both interfaces see each other? interface FastEthernet0/0.2 description VLAN 2 to switch A encapsulation isl 2 ip address 192.168.1.254 255.255.255.0 no ip redirects no ip directed-broadcast interface FastEthernet0/1.2 description VLAN 2 to switch B encapsulation isl 2 ip address 192.168.2.254 255.255.255.0 no ip redirects no ip directed-broadcast Two separate subinterfaces of two separate physical interfaces connected to two different LANs, but with the same ISL encapsulation "color".

Re: stupid questions
There is one way to do this. You can create a Bridge Group Virtual Interface (BVI) . Please see the following URL to get you started: http://www.cisco.com/univercd/cc/td/doc/product/software/ios121/121cgcr/inte r_c/icdlanin.htm You can search cisco's website for more details. It is not perfect by any means but it might get done what you are after.

Re: Catalyst 6509 supervisor engine with MSFC
> I got a Catalyst switch with supervisor engine 1A with MSFC. Without configration, notice there is route shown below. Why is that so? What do > > EOBC0/6 meant? > > C127.0.0.0/8 is directly connected, EOBC0/6 I can't say with 100% certainty, since I don't have a 6509 handy :-), but I have a few ideas. The CAT5k uses a similar syntax to describe the bus connection going to the RSFC. In this particular case, it represents an Ethernet on board controller located at bus number 0, device number 6. This can be verified with the "show eobc" command after 12.07 code, or possibly using the "show interface" command on your RSFC for CAT5ks. I believe that the virtual interface for the CAT5ks is an IBC0 (interface bus controller 0). This is not documented very well in the product DOCs. Also, if you ever get a status on other than up/up, you may have a problem where the RSFC/MSFC meets the Switching Engine. I had an RSFC go bad and it gave an up/down indication on the "show interfaces" command on the RSFC.

Question
Can anybody please help in solving this problem? A router is connected to a T1 line which has the maximum speed of 1.544mbps. The router begins to forward 64bkps packet at 5000 packets per second, there are 500 buffers available. Approximately how long before the link is complelety saturated, the buffers are full and the router begins to discard. Thanks. Arun = Arun Upadhyay SE Engineering MCSE CCNA CNA __ Do You Yahoo!?

RE: Frame Relay problem
Title: RE: Frame Relay problem Hmm...well, you don't give us a config or show version so we don't know for sure what the LMI settings are or what the IOS version is. However, by the show interface you provided, it looks as if LMI is to blame. Newer IOS autosenses the LMI type, but still, I don't trust it. If you have an older IOS or you have a newer IOS that is "autosensing", I would hard code the LMI type. Also, since IOS sets the LMI type to Cisco by default, when/if you hard code it, you might try setting to use ANSI LMI. Good luck!

SmartCertify CBT software for study
Title: SmartCertify CBT software for study Does anyone out there have experience/opinions on SmartCertify's (www.smartcertify.com) CBT offerings? I'm looking at possibly purchasing their Cisco IMCR package, which, I'm told, leads one through all sorts of theory about routing/switching (to fill in any gaps your current education left), information about the routers themselves (how the backplane operates, etc.), and includes a section that simulates IOS configuration of everything from setting the hostname to configuring BGP and IOS upgrades. Not only that, but the salesman told me they guarantee that you'll be ready for and PASS your CCIE lab (not written - he was specific) once you can work your way through the whole CBT. I was a bit skeptical, but he was insistent, so I'm interested in checking it out. But for such a magical product I was expecting the price to be on the order of $5 - $10K. Turns out it's only $1499. A guarantee like that for the price of a router is just too good to ignore, so I wanted to get some feedback from anyone that knows anything about these. Thanks! - Don

Michael Bray wrote: > > So to clarify, would you agree with the statement that the PHY layer is > synchronous, but the ATM layer is Asynchronous? > hmmm nope - the ATM layer is where the blank cells are put in, so actually its still synchronous, its just that the data coming into it can be asynchronous. Actually you can run (synchronous) ATM over an Asynchronous link, as long as nothing else is using it, its deterministic, and the the stats of the link are within the required stats for the QoS, hence you can actually transmit ATM over point to point ethernet (if you *really* wanted to) :) Im not sure what happenned to ATM ethernet though, I havent heard anything on it for ages - there was a CIF forum at one stage (Cells In Frames). The synchronisation for ATM is done at the ATM layer, and because of that, theres always something to send, so you can make full use of a synchronous physical layer as well, hence the high speed links.

Re: your mail
My company's experience is that the power specs are grossly overrated. For a 12008 with dual dc supplies, we us a 25 amp circuit with a 20 amp breaker for each power supply.

Re: Verizon BGP
There may be some truth in both sides. As part of a multihoming strategy, it is perfectly reasonable for ISP 1 to advertise space associated with ISP2, when the space being advertised is a subset of the ISP 2's allocation, and ISP 1 learns about the prefix(es) from a mutual customer. It is also perfectly reasonable that ISP 1 would not accept the advertisement, or possibly accept it but not export it, unless there is some coordination between ISP 1 and ISP 2 that ISP 2 accepts the idea of part of its space being advertised. This might be coordinated by personal contact of routing engineers in both ISPs (and the customer if the customer understands routing at this level), or by having all parties register consistent routing policies in the routing registry system. **NOTE: New CCNA/CCDA List has been formed.

Passed CID
Hello. I passed CID today on my first attempt. The score was 77%. I didn't feel it was so vague, because I prepared enough, I think. I prepared with Cisco Internetnetwok Design from CiscoPress, and Boson CID Practice test #1,#2. Boson CID #1 was very useful , but #2 was too easy and simple to prepare. Questions in #1 require pretty deep knowledge and I could make my knowleade deep by studying and answering to the questions.

Re: Verizon BGP
You need to have a public ASN before you can do this. Arin is very strict when giving out IP addresses and granting an organization their own block of IP's is extremely difficult to justify. Also they will not issue less than a /20. I don't know to many companies that would qualify for even a fraction of this space. If you have a public ASN then there is no reason that your ISP should not advertise out your other blocks of addresses. The only thing wrong with this scenario is that the global routing table will grow exponentially with all those more specific /24's being advertised in addition to aggregates - Original Message - From: "Dave Humphrey" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]>; <[EMAIL PROTECTED]> Sent: Tuesday, October 10, 2000 11:08 AM Subject: RE: Verizon BGP > I've never heard of this practice either.

RE: Verizon BGP
I am peering with UUNet and Verizon and I am advertising Verizons and UUNet's address through UUNet and it does show up as a /24s. UUNet had a static route for my /24 and I asked them to remove it and they did. So, now my routes for my /24s show up as /24s. Verizon's engineers not only could not figure out what I was trying to do but also pointed the finger in every direction. I've talked with 5 engineers and 1 manager. Now, they want me to talk to the BGP team which and I quote, "have banker hours." They said I have to set the metric higher than UUNets then they said that I am pointing the address at Null0. It is not their business what I do with that traffic once it gets in and yes I do have more specific routes for the block. The problem had nothing to do with the metrics since I removed the advertisement through UUNet. I called UUNet and talked to a junior engineer, he took down what I wanted to achieve and took it to a senior engineer and got my BGP route advertised in 5 minutes.

RE: Verizon BGP
I've never heard of this practice either. An ISP will generally advertise his own address space or PI space. Never that belonging to another provider. Which AS are you supposed to use to originate the addresses from? Do you use a private AS number and strip it off upstream?

Re: Verizon BGP
HHHm. I'm currently multihomed between UUNet and AT&T. Now, I'm actually advertising UUNet's address space to AT&T, but looking through the BGP feed from UUNet, I can pick out a ton of address space that you claim to originate, but isn't actually yours. I actually, almost had the reverse config if AT&T's DS3 and OC-x pricing hadn't been so high, and I was told that it wouldn't be a problem. I'll just pick out one, and let you do the rest of your homework. How do you explain 12.96.91.0 which is actually AT&T, but you claim to originate While I know this used to be UUNet's policy, times have obviously changed.

MCRI! MCRI! MCRI!
Are there any books geared for Managing Cisco Routed Internetworks (MCRI 640-443)?? I've browsed Cisco's website along with Amazon.com and can't seem to find a book geared for this test. Any help is greatly appreciated!! Thanks! **NOTE: New CCNA/CCDA List has been formed.
