Source Routing
Kind of a bizarre situation, but... We have a large, productional network that can't be messed with too much. Basic network could be looked at like this - core(5500rsm) - distro(4700) - access(1720s) / ---/ What we need to be able to to do is route a couple of the customers on the 1720s towards the new internet connection until we are ready to swing everyone over to it. Since we already have a default route to the existing internet connection, what is the easiest way to do this? I've considered creating tunnels between the 1720s and the new internet routers, but have always heard things about tunnels and CPU usage. It is an ethernet environment only, so I don't know of any way to source route. Any suggestions? _ Get more from the Web.

Re: Coil pinnaccle header
I haven't seen that error yet, but I can telly you this. The COIL chip is sits on the 6500 Fast Ethernet Blades. Each Coil chip is responsible for up to 12 FE ports. They are mostly responsible for TX & RX buffering, CRC checks, and queing The PINNACLE chip is found on the Gig E and Fast E line cards. Each Pinnacle chip handles either 4 Fiber XCVR ports or 4 Coil chips. It can handle CRC checks, Queueing, putting packets on the switch bus, and so on. Don't know if that helps you any. Either way, if it is a group of 12 ports or a group of 48, it is still that entire blade that would have to be replaced to get them all working.

Re: Clocking Question
My understanding is that the CSU/DSU usually acts as both a DCE device and a DTE device. Although depending on how you configure it, it can be any combination. Usually you configure it to provide clocking to your equipment (router) so it is DCE to the router. And, you usually configure it to accept clocking from the line coming from the service provider, so it is DTE to the network. So, normally the router is working with its default setting - DTE. If you have routers in a test lab, or a back to back cable running under the floor or something, you don't need a CSU/DSU, and you can configure one router to provide clocking to the other. Hope that helps, Mike >Hello Group, >My Name is Rajgopal and I am based in Bombay,India.I have a question for >you >guys. >I have read in the CCNA 2.0 Exam Certification guide by Wendell Odom that a >DTE is the equipment that receives the Clocking information from a DCE >which >is the device that sends the clocking information for sync Links and at the >same time he also says that a serial line comming from the ISP is connected >to a CSU/DSU which in turn is connected to your serial port in the router >and the CSU/DSU is the device which gives the clocking information for the >sync links. >Whereas the ICRC book says that by default the Cisco router is a DTE >equipment and the minute we implement the clocking command on a particular >serial interface then it becomes a DCE device. >Correct me if I am wrong but for the clocking command to work on the >enterprise side we have to enable the clocking command.Then does that >interface become a DCE ??And if it becomes a DCE then doesn't it defy the >rule that a DTE is connected to a DCE ?? >The ICRC book also says that in case if you don't have a CSU/DSU u have to >use a back to back cable to connect the 2 routers and the interface on >which >u implement the clocking command becomes a DCE interface.But don't u think >that its the ISP which gives u the clocking information?? > >Please enlighten me on this subject as soon as possible because I have my >CCNA exam on the 21st of Sept,2000 and I would like to be clear on as many >concepts as possible. > >Many thanks and please help me out. > >Regards, >Raj. > >P.s U can email me on the above mentioned address. _ Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com.

Re: output queue drops
Look at your load - 224/255 And that is a five-minute average. It looks like this link is pretty much maxed out. You are getting queue drops because you don't have enough wire speed for all of the traffic you are trying to push out. You can increase your queue depth to have it hold more packets to help when traffic is bursting, but if this is a constant occurance what you really need is more bandwidth.

Re: Traffic shapping,
How about this - interface s0 custom-queue-list 1 queue-list 1 queue 1 byte-count 1500 queue-list 1 queue 2 byte-count 6000 queue-list 1 protocol ip 1 tcp 80 queue-list 1 protocol ip 1 tcp 20 queue-list 1 protocol ip 1 tcp 21 queue-list 1 default 2 This should set up the serial interface to use queue-list 1 for custom queueing. Queue list 1 is set to sample 1500 bytes per round from bucket 1 and 6000 bytes from bucket 2. It is then set to put anything that is on tcp ports 80 (HTTP), 20 (FTP), or 21 (FTP) into bucket one. Everything else (default) is put into bucket 2. This will not shape the traffic to 20/80 unless you are filling up the T1 and there is a requirement for queueing. Once it requires queueuing it will put FTP and HTTP traffic into bucket one and everything else into bucket two. It will then pull packets from bucket 1 until it hits the 1500 mark and then go to bucket 2 and pull until it reaches the 6000 mark. It will then return to bucket one. That means that every round of sampling from the buckets, bucket 1 gets 1500bytes out of 7500 total, or 20%. Bucket 2 gets 6000bytes out of 7500, or 80%. It isn't an exact way to do this, and it only happens when traffic on your T1 is hitting the point where queueing is required, but it should guarantee that HTTP and FTP doesn't flood out your other traffic. > >Dear Group, > >i've got the following problem.or question >May your experience helps. > >We have running an new INTRNET server wich is also used by or Internationl >users worldwide.

Re: Traffic Shaping
There is a 'load-interval' command that you can use to specify how often the router averages the load on an interface, in 30second intervals. Normally when you do a 'show interface' you get a five minute averate. With the load-interval command you can change that.

Re: OT: Ethernet Trivia
Good question! I would guess that they would both arrive at the destination at the same time. The difference would be that the 100Mbps packet would finish transmitting first. The difference in speed can't be propagation delay since it goes over the same media. So the difference in speeds should be that the 100Mbps link is using less time to signal 1s and 0s and less of a delay between each bit. > >Let's say we have a 10Mbps and 100Mbps interface.

BGP prefix-list help needed
Hi all. I need some help with a BGP prefix list. A consulting group has recommended the following prefix list in order to deny learning networks that should not be learnt from the internet. I don't entirely trust these guys to know what they are doing, so I would like to see what you all say about this before I ask them specific questions. For simplicity, the first part of each line - ip prefix-list seq deny has been left off. All of these lines are deny statements 0.0.0.0/32 0.0.0.0/8 le 32 0.0.0.0/1 ge 20 10.0.0.0/8 le 32 127.0.0.0/8 le 32 128.0.0.0/2 ge 17 128.0.0.0/16 le 32 172.16.0.0/12 le 32 192.0.2.0/24 le 32 192.0.0.0/24 le 32 192.168.0.0/16 le 32 191.255.0.0/16 le 32 192.0.0.0/3 ge 25 223.255.255.0/24 le 32 224.0.0.0/3 le 32 I've tried to work my way through this, and this is what I've got so far: These I understand: 10.0.0.0/8 le 32= 10.x.x.x (private 10 networks) 127.0.0.0/8 le 32 = 127.x.x.x (127 loopback addresses) 172.16.0.0/12 le 32 = 172.16.x.x-172.31.x.x (private 172 addresses) 192.168.0.0/16 le 32= 192.168.x.x (private 192 addresses) 224.0.0.0/3 le 32 = 224.0.0.0-255.0.0.0 (class D & E addresses) Are both of these statements necessary? Doesn't the second one include the first? 0.0.0.0/32 = 0.0.0.0 0.0.0.0/8 le 32 = 0.x.x.x I think I can understand this, I've heard that anything less then /19 is not advertised across the internet. But, if that is true, what about the rest of the networks? 0.0.0.0/1 ge 20 = 0.x.x.x thru 127.x.x.x, with mask /20 or more Do these have somehthing to do with the above statement? 128.0.0.0/2 ge 17 = 128.x.x.x-191.x.x.x, with mask /17 or more 192.0.0.0/3 ge 25 = 192.x.x.x-223.x.x.x, with mask /25 or more What the heck are these addresses? 128.0.0.0/16 le 32 = 128.0.x.x 192.0.2.0/24 le 32 = 192.0.2.x 192.0.0.0/24 le 32 = 192.0.0.x 191.255.0.0/16 le 32= 191.255.x.x 223.255.255.0/24 le 32 = 223.255.255.x Any help would be appreciated _ Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com.

Re: Inverse Mask
Remember that with ACL masks, 1s = don't care. so, for a mask of 0.7.255.255 you have - .0111.. so, when used with 10.0.0.0 - You have to have 10 in the first octet (no ones) It doesn't care what is in the 3rd and 4th octet (all ones) The second octet is the one to watch. because the mask is 0111 the first five bits have to remain as they are in the ip address - 0 the last three bits can be either one or zero, doesn't matter so, they can be anything from 000 to 111 so, your IP address can be 0 000 to 0 111 which gives you 0 - 7 in decimal so the mask fits 10.0.0.0 to 10.7.255.255 hope that helps Mike > >I need help in understanding inverse masks that are used in network & >access >list commands.

Re: Two DLCI numbers?
The DLCIs aren't always given by the provider. Depending on the provider and how much busniness you do with them, you can request specific DLCIs. The way we are doing it is multi-point frame connections from our central offic to our remote office. All PVCs connecting to a given T1 at our central office use the same DLCI at the HDQ site (201) and then use different DLCIs for each of the remote sites (301-399) The next T1 at HDQ is given a different DLCI (202) and the remote sites connecting to that T1 are again numbered (301-399) When you have a lot of connections (around 7000 in our case) it makes it easier to manage like this. If there is a problem, we can use the DLCI pair to identify which T1 it is in our HDQ, and which of the DLCI nubmers belongs to the remote side of the connection. > >Hi all >While I was reading a cisco book, I came across the >fact that DLCI number has only local significance >because there might be more than one DLCI number >associated with one pvc. >Why would any pve in frame relay network have two DLCI >numbers? >I know that DLCI number is given by frame relay >service provider. >Can someone explain this? > >Thanks in adv. > >jeongwoo _ Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com.

BGP - maximum-list
Has anyone used the maximum-prefix command on a cisco running BGP? It is supposed to keep a neighbor from going crazy and swamping your router with too many routes by limiting the number of routes that can be learned by the router. What would be a good number to set that at to allow a full BGP table, plus growth, and still protect the router. Or does no one use it? _ Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com.

Re: IP route cache
It determines how the router switches packets. If you use 'ip route-cache' then the router will be fast-switching the packets. The router keeps a cached memory full of recently used (which should often equal heavily used) routes & destinations. When a packet comes in it can use that cache to determine where to send the packet without having to do routing lookups. If you use 'no ip route-cache' then the router will be process-switching and will do route lookups for every packet. I think Cisco recommends that if you are running a serial link that is slower then T1 speed to go ahead and do 'no ip route-cache' because the link is so slow (number of packets so low) that the time saved by the route-cache isn't worth the memory of keeping all of that information. Also, if you have multiple paths to the same destination and are doing fast-switching, the router will load balance the traffic on a per-destination basis because once the destination output port is in the cache all traffic following it will go out the same port. Process-switching will load balance on a per-packet basis since each packet is looked at individually. hope that helps, Mike > >Can someone describe why I would want to use the ip route-cache (or no ip >route-cache) command.

Re: ACL Deny Statement & Wildcard
use this - access-list 103 deny ip 100.16.0.0 0.1.255.255 An easy way to look at it is that if your address ranges are consecutive then the .16 above is the starting address and .1 is the number of networks. So it blocks 16-17. Or look at bits - .16 = 0001 .17 = 00010001 in the mask 0 = must match, 1 = don't care, so use 0001 The .238 mask you put below would look like this - 11101110 So it would allow the following networks 0001 00010010 00010100 00010110 00011000 00011010 00011100 0000 0011 00110010 00110100 00110110 00111000 00111010 0000 0010 and so on. The only rule would be that the 5th bit had to be a 1 and the 1st bit had to be a 0 (right to left) hope that helps. Mike > >I need to deny 2 consecutive network ranges.

Re: no ip directed-broadcast?
no ip directed-broadcast - this means that someone can't ping your networks broadcast address. This was used in denial-of-services attacks. Someone would ping the broadcast address, and every machine on the network would answer. no ip mroute-cache - this should only be used on slow (T1 or slower) serial interfaces. It turns off route-caching for multicast packets. On slow links Cisco says that it takes more memory and processor time to cache the routes and look up the cache then it does to process switch the packets. > >Hi, >I am trying to figure out 2 things on interfaces: >When I configure a serial or Ethernet interfaces, there is a default >setting >that says no ip directed-broadcast or no ip mroute-cache? >I have looked up books for this explanation but cannot find any.

Re: Load Balancing between two routers
Do you use any routing protocol between A, B, & C?? Most of the routing protocols can be set up to load balance across multiple different routs to the same network if the metrics are the same. E/IGRP can load balance even if the metrics are not the same. Note - A is probably set for fast-switching to B & C since it is on a LAN interface. When you are fast-switching the router will only load balance on a per-destination basis. If you want it to load balance on a per-packet basis you have to turn off fast switching by turning off route cacheing. Hope that helps, Mike > > > >I have three routers connected via token ring, A, B, & C. > >Routers B & C both have serial links to the same location. > >Can I configure router A to balance the traffic between routers R & C. > >Currently using static routes in A to send traffic to B only. > >Thanks! > > > >___ >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] Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com ___ 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: Frame-relay traffic shaping question
The easiest way to do this is to only configure the CIR and Line speeds and let the rest default. Example commands - int s0 frame-relay traffic shapping Enable FRTS on the interface frame-relay class ExampleClass Shape as defined in map class frame-relay map-class ExampleClass frame-relay traffic-rate XXX YYY ### XXX = CIR, YYY = Max Speed traffic-rate adaptive-shaping becn Use BECNs (not foresight) for for thottling If you set XXX to 512K and YYY to port speed, he will transmit at port speed unless he receives BECNs from the network, and then he will throttle down to 512K. If you set both XXX and YYY to 512K he will always transmit at 512K Depending on your service provider and how congested their network is you may be able to go in and buy a small CIR like 64K and then ignore that and have your router set to send at 512K. If you do that and some time in future your SP starts dropping packets (because they are over CIR) you will have to go to them and buy up your contracted CIR, but until then you can save some money. We've been running AT&T Frame Relay for a couple of years and have yet to receive a single BECN. It is possible to go in and specify mincir, Bc, Be, etc. But unless you are going VOFR or some other application that has specific needs using generic FRTS will cover just about everything. Hope that helps, Mike >Guys, > >What are the parameters that I should configure on the router to control >the >bandwidth usage of the user on a frame-relay configuration. >For instance, the user has T1 line and I need to provide him only 512k.

Re: CIT next week
I just finished it yesterday. Out of all the tests I think CLSC was the most poorly written, but CIT comes in a close second. The questions are very vague, and you often have to guess what they are looking for. They aren't extremely hard though, and if you are familiar with the topics you should be able to work it out. There are some fill in the blank questions for commands, and I even had one of those "move the boxes to the correct place" type questions. Don't stress too much over the packet trace questions. You do need to have a general idea of what a packet trace output looks like, and what does what. But, they decode the packet for you, so as long as you can understand what the decode written out to the side means you'll be ok. You don't have to memorize which hex means what in a packet. There was more appletalk on this test then any I've had before, but even still that was only a few questions. I'm not sure if this test is adaptive or not, but they sure beat the crap out of me with ISDN questions. Make sure you know the show/debug/troubleshooting stuff for ISDN. There were a fair number of Cisco web-site questions. Know the URL, the basic areas (marketplace, software center, etc) and a basic idea of what is in each There were a few questions on troubleshooting tools, but they were fairly basic as long as you have an idea of what the common tools are and what they are used for. hope that helps, Mike CCNP as of yesterday :) > >All, > >I am taking CIT next week and need some advice from people that have taken >this exam recently.

Re: Frame-relay traffic shaping question
I'm not very familiar with generic traffic shaping. But, at first glance it looks like it is basically the same thing as frame relay traffic shaping except that it does not dynamically change based on network congestion because there is no method set up to notify the router of any congestion encountered. Using 'frame-relay traffic-shaping' indicates that the router can change the traffic rate based on becns or foresight notifications of congestion. You will have to use a 'frame-relay map-class' to tell the router how you want to shape the traffic. With generic traffic shaping you can specify the rate directly on the interface because you do not need to tell it what sort of congestion notification to listen to. When you use the command 'frame-relay traffic-rate 64000 128000' (for example) you get the following values - mincir - 32000- This is amount sent when congested CIR - 64000 - This is the amount to send with no congestion bc - 64000- This is the amound to send per interval be - 64000- This is the burst amount to send in the first interval tc - 125 - This is the interval time in milliseconds The router will send out traffic in the following pattern each second (for tc=125 or 1/8 or a second) when there is no congestion bc+be / bc / bc / bc / bc / bc / bc / bc so for this config it would send - 128000 / 0 / 0 / 0 / 0 / 0 / 0 / 0 then it would repeat that for the next second. By doing it like this the router attempts to send the full amount of traffic every second. You can go in and specify the Bc, Be, CIR, and mincir to be other values to try and shape the traffic in different ways, but there is rarely any need to. For example, if you were to use the following config map-class frame-relay test frame-relay cir 128000 frame-relay mincir 64000 frame-relay bc 8000 frame-relay be 64000 you would get the following traffic pattern - 72000 / 8000 / 8000 / 8000 / 8000 / 8000 / 8000 / 8000 So, you would still get 128K in the one second. The problem with this is that the router can only bust beyond Bc (up to Be) when it has excess bandwidth available. So, if it keeps sending at 8000 then it will be at 64000 each second after that. Until it has transmitted a second with less then 64000. Lets say in one interval it only transmitts 6000. So, next interval it was an excess of 2000 that it can transmit as Be. This can continue until it was built up 64000 which is the max Be it can ever have. Its sorta like roll-over minutes for cellular phones :) By using the the 'frame-relay traffic-rate xxx yyy' command you are fooling the router into sending max Be every second. It thinks its Bc is 64000 so the in the intervals it cant send traffic (because it hit line speed in the first interval) it builds up credit again so it can burst at full Be on the next seconds interval. It really depends on how you want your traffic shaped and what sort of applications are running over the link. But, if they aren't extremely time sensitive, the generic command should work. The one thing to watch for in the 'frame-relay traffic-rate xxx yyy' command is that it assumes your mincir is 1/2 your average speed value. So, if you set your average to your contracted CIR and the router encounters congestion, it will slow down to the mincir which is half of that. To get around this you can set your average speed to double your CIR. If you order your CIR at 1/2 your line speed (128K port, 64K CIR) you can use something like this 'frame-relay traffic-shaping 128000 128000' The router will run at 128000 unless it hits congestion and then it will run at 64000. Hope that helps.

Re: FAst Packet Switching
For IP traffic, on the interface you want to disable fast switching use the following commands - 'no ip route cache' - this turns off fast switching for unicast 'no ip mroute cache' - this turns off fast switching for multicast note - not all routers and ios versions accept the mroute cache command. but you probably don't need to worry about it unless for some reason you have an unusually high number of multicast packets. hope that helps, Mike > >Hi all: > > >How can I disable the Fast Packet Switching feature (if it´s possible) in >Cisco IOS 12?

Re: new 3600 problems
If you don't have a good working ethernet port, you'll have to xmodem the ios into the router. The way to do this is - 1) Reboot the router. 2) While it is reloading hit the break key to get it into rommon mode 3) type 'confreg' at the prompt. The router will ask you if you want to change the register 4) Enter yes, and hit return to accept default values until it asks if you want to change the console port speed 5) Tell it yes and it will give you a list of speeds. Pick 115200 6) Keep accepting default values after that until it gets back to asking if you want to change the register again. 7) This time tell it no. It will now save your register (btw - I think it is 39xx something something) 8) Tell the router to reset 9) While it is rebooting, set your hyperterm (or whatever program) to work at 115200 instead of 9600 10) Hit the break key while the router is reloading to get back into rommon mode 11) At the prompt enter 'xmodem' 12) It tell you some stuff, and eventually be ready to accept an xmodem download. Tell hypertem to xmodem the file to the router 13) When it is done, reset the router again 14) It should now load ok. 15) Once you are in to it, configure the ethernet port. 16) After you do that, you can telnet into the router, go into config mode, set the config register back to 0x2102 and the console line speed back to 9600 You can do this without messing with the config register and port speeds, but if you do it will take about 2 hours to xmodem the ios to the router instead of 15 minutes.

Re: CCDA question-512 bit times
Fibre doesn't actually break the 512 bit-time rule. You still need to keep your network under 512 bit-times from worst-case station to station. Fibre can have the longer lengths because it doesn't sucumb to attenuation as fast as copper. The differences in propegation time between copper and fibre are very slight. And, if you didn't have to worry about attenuation you could run 412 meters on fibre and 370 meters on copper. Take a look at your network, find the two stations that are seperated by the most cable and devices, and then follow the fomula in the book, and see what sort of number you come up with. If you think it is completely off, send a little ascii art picture showing what cable lengths and devices are in there.

Re: Router Security commands
no ip redirects - If a router has to direct a packet out the same interface it came in on (usually because it is configured as the incorrect default-gateway for a packet from a workstation) then it will send that packet on, but also send an ICM Redirect message to the host that sent the packet. This command causes the router to not send the redirect message. no ip directed-broadcst - This denies broadcasts destined for a specific, remote, subnet no ip proxy-arp Someone help me out if I explain this wrong. If a workstation ARPs for another workstation that is not on the local net (perhaps because it doesn't have a gateway configured, or becaues it has the wrong subnet mask) then the router will respond to the ARP with its own address. The workstation will then send the packet to the router, and the router will forward the packet. This command disables this feature.

Re: Stuck in ROMMON mode
If you are going to have someone console in locally, do this - In rommon mode, type confreg, it will ask you if you want to change the register, tell it yes. It will give you a bunch of options. Tell it yes for change the console port speed. Set it for 115200. That will disconnect you from the router. Set the hyperterm (or whatevery you are using) for a port speed of 115200 and try again. You should be able to get back in. Try to do XModem then. It will be much faster (15/20min instead of 2hrs). Once you do that and reload the router you'll have to telnet into it to change the register back to 0x2102 and do a 'no line speed 115200' on the console line. That should get you up and running without doing a 2hr Xmodem. Hope that helps, Mike > >First time posting, so bare with me. Need help with this, I was doing IOS >upgrade to a 3640 remote router.

RE: Preventing password recovery
I've had a couple of suggestions to fix this, but nothing that works so far. The best choice would be to lock it up somewhere, but it is on customer-owned premise, so other then telling them they shouldn't be messing with it, we don't have a fool proof way of keeping them out of it. A couple of answers I've tried that haven't worked - 1) Change the config register to 0x2002 - Disabling the break key is on by default. This allows someone to use the break key to enter rommon mode during normal operations (oops, luckily I have a test router to play with) 2) Change the config register to 0x102 - I didn't notice any diference in this at all with this setting. 3) Use the command "no service password-recovery" - Which seems to want to work, but I get a response from the router saying "Password recovery disable mode is not supported by the current ROMMON. Please upgrade the ROMMON if you want to use this feature." Which is kind of funny since it has 12.0.3(T) in the ROM. I'm not sure there is anything else you can change the 1700's to.

Re: RSVP & WFQ
I'm not familiar with RSVP, can I can help with WFQ. WFQ is enabled by default on nearly all serial interfaces with speeds less then 2Mbps. (Exceptions are if you are using SDLC, X.25, LAPB, compressed PPP, and maybe a couple others). WFQ is able to sense the various 'conversations' between end stations by identifying packets based on a couple of things - Source/Destination network address Source/Destination MAC address Source/Destination port number Frame Relay DLCIs If queueing is necessary on a link, then packets are put into the fair queue. They are serviced from the queue in order based on the time of arrival for the last bit of each packet. So, even if a big FTP packet arrives into the router before a small E-Mail packet it is likely that the E-mail packet will get transmitted first because the E-mail packet finished arriving before the FTP packet. Because they service the queue like this, smaller packets will have a greater chance of being transmitted first which gives them a semblance of a higher priority. The router can also keep track of the 'conversations' and small packet conversations can have their queued packets interleaved with the packets of a large packet conversation like FTP. This keeps them from being held up in queue too long if there is already a bunch of packets in queue for the large packet conversation. The only adjustable variable for WFQ is the congestive discard. If a high-volume/large-packet conversation has packets in queue, it can only have the number of packets up to the congestive-discard value. Once the number of packets reaches that number the router no longer queues packets for that conversation until the number of packets in queue drops to 1/4th the congestive-discard value. I don't know about how RSVP works, but I can explain some about how Frame-Relay traffic shaping works in association with queues, and it may be pretty similar. With FRTS you can give each PVC a CIR & Burst speed. If the traffic for that PVC goes over those amounts it needs to be queued. After the router determines that it needs to be queued, it sends it to the queueing process in effect on that PVC (WFQ for our example). The router then begins queueing and de-queueing the packets as explained above. I would guess if you reserved 50K of traffic on a link, and the link was full, and you had more then 50K of traffic to send, the remainder of the traffic (after the 50K) would be queued up, and then the queueing process would determine in which order packets were serviced until the traffic load dropped and the queue had been emptied.

Re: load balancing multiple T1's
If they are equal cost, most any routing protocol can do this - RIP, EIGRP, OSPF, etc. One note on this though - If you are no process-switching, the load balancing is done on a per-destination basis. Meaning all traffic for one host is sent on first T1, all traffic for second host goes on second T1, etc. At T1 speed, you can do "no route-caching" to slow the router down to process switching. It will then load balance on a per-packet basis. > >Hi !! > >I need to load balace four T1 circuits between point A and point B.

Re: load balancing on Rip
The router is probably fast-switching. Which means it is load balancing on a per-destination basis. All of your traceroutes are for the same destination, so they are going the same route. On the serial interface, if it is T1 or slower, do a "no ip route-cache" That will turn off fast-switching, and make the router process switch the packets. It is then supposed to load balance on a per-packet basis instead of a per-destination. > >The admin distance is 120, hop count is 2 for two entries to the same >network yet when I do a traceroute it only traces through the first entry >Duck >- Original Message - >From: Brian <[EMAIL PROTECTED]> >To: Donald B Johnson Jr <[EMAIL PROTECTED]> >Cc: Atif Awan <[EMAIL PROTECTED]>; Agnelo D'souza <[EMAIL PROTECTED]>; ><[EMAIL PROTECTED]> >Sent: Monday, August 28, 2000 8:58 AM >Subject: Re: load balancing on Rip > > > > On Mon, 28 Aug 2000, Donald B Johnson Jr wrote: > > > > > How come when I do a traceroute it only shows that one path is being >used. > > > Thanks > > > Duck > > > > show us the route table output,then show us the traceroute. > > > > Brian > > > > > > > - Original Message - > > > From: Brian <[EMAIL PROTECTED]> > > > To: Donald B Johnson Jr <[EMAIL PROTECTED]> > > > Cc: Atif Awan <[EMAIL PROTECTED]>; Agnelo D'souza ><[EMAIL PROTECTED]>; > > > <[EMAIL PROTECTED]> > > > Sent: Monday, August 28, 2000 8:28 AM > > > Subject: Re: load balancing on Rip > > > > > > > > > > On Mon, 28 Aug 2000, Donald B Johnson Jr wrote: > > > > > > > > > Could You show me the commands to load balance RIP please.

Re: Help on Frame-relay Traffic-shaping command
For frame-relay traffic-rate 32000 64000 16000 32000 is your average speed, it is what the router will transmit at if there is no congestion. The router assumes 1/2 average speed for CIR, so it will back off to 16000 if there is congestion. 64000 is what it can burst up to I am not positive on the last value, but I think it may be the burst amount that can be sent per inteval in order to get the traffic up to the burst amount for that second. If you have 150K of traffic to send, and your interval is 125ms it will look like this - Second 1 - 20K / 20K / 4K / 4K / 4K / 4K / 4K / 4K = 64K, Total = 64K Second 2 - 4K / 4K / 4K / 4K / 4K / 4K / 4K / 4K = 32K, Total = 96K Second 3 - 4K / 4K / 4K / 4K / 4K / 4K / 4K / 4K = 32K, Total = 128K Second 4 - 4K / 4K / 4K / 4K / 4K / 2K / 0K / 0K = 22K, Total = 150K If there was more traffic to send, the router could send a total of 42K in the 5th second, because it would have built up 10K of credit towards bursting in during the 4th second. I am not familiar with traffic shaping using the second set of commands, so I wont comment on them. For the commands - >frame-relay cir 64000 >frame-relay mincir 64000 This means that the route will always transmit at 64000 no matter what. Because there is no Bc set, it will never go over CIR, and because the mincir = cir, it will never slow down, even if there is congestion. If you want to get 32K average and 16K minimum, you can use the following command - frame-relay traffic-rate 32000 32000 That will set the average rate to 32000, the burst rate to 32000, and the mincir (what the router backs off to during congestion) to 16000 By doing this, the router will run at 32K constantly unless it receives congestion notification. You also need to use the 'frame-relat adaptive-shaping becn' to get the router to listen to becns and slow down. Hope that helps. > >Hi, >I have studied following command at cisco website but I still have problem >to understand how the parameters work. >If you can give me some example of those command, I will really appreciate >that. > > >1. >Frame-relay traffic-rate [bit-rate [burst-size][excess-burst-size]] > frame-relay traffic-rate 32000 64000 16000 > look like 32000 is CIR. what about 64000 and 16000. > Is there any different to use "frame-relay cir" command ? >2. >frame-relay traffic-rate 1544000 >frame-relay adaptive 64000 >Documentation tell me CIR is 64000 and access rate is 1544000.

Re: packets
Since you didn't specify the protocol, I am going to assume you mean for a TCP connection. When one side wants to set up a connection with the other side, it does a "three-way handshake" by doing the following: A -> Sends SYN=1, ACK=0, SEQ=1000, ACK#=0 B -> Replys ACK=1, SYN=1, SEQ=5000, ACK#=1001 A -> Replys ACK=1, SYN=1, SEQ=1001, ACK#=5001 When the conversation is over, if both sides wants to close the connection, they do a "graceful close" by doing the following: A -> Sends FIN=1, ACK=1, SEQ=2000, ACK#=6001 B -> Replys FIN=1, ACK=1, SEQ=6001, ACK#=2001 A -> Replys ACK=1, SEQ=2001, ACK#=2002 The SYN bit is letting the remote side know to synchronize the SEQuence number it should be expecting. The ACK bit indicates that the sender has recieved a packet from the remote side, and it is now expecting to receive a packet with the sequence number indicated in the ACK# field. The SEQ field is a randomly generated number that the sender generates to show where it will start at.

Re: priority list
I'd say look at Cisco's web pages to be sure, but I think it is number of packets in queue, max size of queue allowable, and number of packets that have been dropped by that queue. I don't know if it is 'normal' to put telnet in the high priority queue, but it probably won't hurt since telnet traffic usually so light it won't impact any other applications. >Dear all, > >I've configure a priority list, after the command show int s0, the >following >is displayed: > > Queueing strategy: priority-list 1 > Output queue: high 0/10/0, medium 0/40/0, normal 0/80/0, low 0/80/0 > >what do the numbers means 0/10/0 etc? > >I've assign telnet to the high queue to prevent delay. >default is normal. > >Thanks > >-- >Jacques Lee >CCNA > Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com ___ 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: VLSM Question
The numbers you have might work, but they definately aren't the best to use. I have a couple of comments inline below - >I have four different interfaces on a 2514 router (e0,e1,s0,s1), each >interface is on a different subnet, and the mask is 30 bits. Here's they >are: >int e0 = 172.16.10.4 /30 >int e1 = 172.16.10.8 /30 >int s0 = 172.16.10.12 /30 >int s1 = 172.16.10.16 /30 >( I only want two addresses per subnet) Those are good subnets for two devices per subnet, but not to be put on the interface. The .4, .8, .12, and .16 are the 'net' addresses for those subnets. You would want to put .5, .9, .13, .16 on the actually interface. with .6, .10, .14, and .17 being the remote devices and .7, .11, .15, and .18 as the broadcast address for those nets. I wasn't too sure from your letter if you were pointing out the subnets that would be placed on each interface, or the actuall IP address. >I'm running OSPF routing protocol on this router.

Well, 172.16.10.0/27 will give you a netmask of .000/01010 That wil summarize all networks from .0 to .31 - so, it will cover the range you need. But you will have to make sure not to use the .20 through .31 anywhere else in the network. This one can't be summarized in one summary-address if you want to keep it to these networks exactly. You would have to use 172.16.10.4/28 which would cover .0 through .15 and then the 172.16.10.0/30 for that range.

Re: full meshed ip unnumbered network
I don't think the second solution would work to well if you tried to put all of the interfaces in the same network space, but 1 and 3 should be ok. I'm not too sure where the worry about load balancing comes in since each router only has one direct hop to the other. There should only be one link to a destination at a time in this design. If a link goes down, it will take the two-hop route. The meshed frame-relay solution is how we do it where I work, but PTP versus FR is mostly a matter of cost and what you need the circuit to do. > >here is the design: > > > ETHERNET > | >1XXX > > /\ > / \ > 2XXX 3XXX > - > / \ > ETHERNET ETHERNET > > >the three routers are seperated by point to point wan >links, my questions involve the pros/cons of >addressing the wan links using various techniques. > >1. make each p2p link its own /30 network >2. make all p2p links use addresses out of the same >pool (i.e. 10.0.0.1, .2, .3, .4, .5, .6) >3. ip unnumbered e0 > >i think that solutions 2 & 3 would cause problems if >one link came down, because only a portion of the >subnet is down if you were doing per packet load >balanceing, then every other packet would drop... > > >as a variation, you colud take the link down between >routers 2 & 3, and make the other p2p's frame relay >links, then have a logical full mesh using pvc's... > > >Comments please.. > > > >= >ciscocabanaboy, CCNP-Voice, CCDP, MCSE, CNX, A+, N+, I-net+, BOFH... > >__ >Do You Yahoo!? >Yahoo!

RE: setting mtu size on a 2611
This is kinda vague, but I know there is a 'fragment' type command that can be used when running VOIP to break down larger packets into smaller ones so that the large packets do not slow down the little ones.

Re: ATM
Actually, I would consider ATM more of a WAN technology that can run in a LAN using LANE. In the WAN it mostly runs on fiber, because of the high speeds that carriers run it at, although you can get it on a coax cable if you get an ATM T3 connection. My understanding (limited) is that AT&T uses ATM for their backbone. Even their Frame Relay connections are converted over to ATM, run across their backbone, and then back into frame to come out the other side. hope that helps some. >Hello, > >This is a very basic question about ATM.

RE: Frame Relay limitations question
Well, to give a little more info on what the article below said, If they are Point-to-Point, you have to create a sub-interface for each PVC, so you are limited to the number of IDBs you can have in a router. I think the numbers in that article might be a bit low, but it might be correct for most models. Our Cisco rep recently told us that a 7200VXR routers were limited to 3,000 IDBs, although I think the VXR chassis is one of those geek things it was talking about :) If they are Multipoint PVCs, the numbers below look pretty good to me, but a bit conservative for a max value. We have a bunch of Cisco 4700s with 16M DRAM, and each of them has 4 T1s on them with 200 PVCs per T1, for a total of about 800 per router. Hope that helps.

Re: Traffic shapping
What you are wanting to do is not strictly traffic shaping, but queueing. Traffic shaping is making sure that you are sending x amount of traffic into the network. It doesn't discriminate between types of traffic. you use it to set your router to send at a minimum of your contracted CIR. With queueing you can determine what sort of traffic which how much of a percentage of the bandwidth. There is two ways you can go about this - 1) with custom queueing you can guarantee that all traffic will get a chance to be sent, and you can change the queue sizes to try and set a percentage. 2) with priority queueing you can guarantee that the mail traffic will go, and the rest of the traffic will go if there is room. For custom queueing, you can do something simliar to this: queue-list 1 protocol ip 1 tcp smtp queue-list 1 protocol ip 1 tcp queue-list 1 default 2 queue-list 1 queue 1 byte-count 1500 queue-list 1 queue 2 byte-count 3000 what this does - line 1 - put smtp traffic in queue 1 line 2 - put x.400 traffic in queue 1 - note: i'm not familiar with x.400, so I don't know the exact command. It would depend on what ports x.400 ran over, and if they were different from smtp. line 3 - put everything else into queue 2 line 4 - send 1500 bytes from queue 1 before going to queue 2 line 5 - send 3000 bytes form queue 2 before going to queue 1 becuase of the queue sizes queue 1 should be able to send 1500 bytes for every 3000 bytes of other traffic. Which means it should be about 1/3 of the total traffic on the link when queueing is needed. So, for a 64K line, that should be about 20K. Note: this is based on average packet sizes being 1500. Again, I don't know enough about smtp and x.400 to say what the real average packet size is, so those byte-count numbers may have to be adjusted to compensate if the real numbers are different. to use priority queueing - priority-list 1 protocol ip high tcp smtp priority-list 1 protocol ip high tcp what this does - puts the mail traffic in the high priority queue. this means that it will always be sent, even at the expense of the data traffic, if the link is congested and has to queue. The other traffic will fall into the default queue which is normal priority. again, I don't know if the second line is needed, it would depend on the specifics of the x.400 protocol. hope that helps some. mike > >Hi all > >I am trying to configure a Cisco 3640 for traffic shaping.

Re: Redistribute Static
The only static route that is redistributed into the routing protocols by default is the default route. And, I know that is true for RIP, you'd have to look and see if it were true for other routing protocols also. If you want other static routes to be advertised you have to use the redistribute static command. hope that helps mike > >I recently attended an ACRC training course where I was told that the >redistribute command was only used to pass information between routing >protocols within one router (i.e. RIP to OSPF).

Re: Can you block CDP with an access list???
I found this on Ciscos pages - CDP sends packets on LANs using the multicast address 0100.0CCC.. So maybe that will help if you can set up an ACL by MAC address. But, I am pretty sure that if you turn off CDP on a router it will not respond to CDP requests from neighbor routers. I couldn't find anything on the web to verify this, but it should be pretty easy to test out. hope that helps mike > >I know you can turn off CDP completely however I do not believe it can be >blocked by an IP access-list as it runs at layer 2. >If I am wrong, I am sure I will be corrected here, but I am pretty sure >that >is accurate based on the fact that CDP uses layer 2. > > >- Original Message - >From: "Aaron Prather" <[EMAIL PROTECTED]> >To: <[EMAIL PROTECTED]> >Sent: Tuesday, June 27, 2000 5:58 PM >Subject: Can you block CDP with an access list??? > > > > If you can what protocol does it use?

Re: suppressing null update
Usually you will see this when you have a distribute list in place and the distribute list is blocking all of the updates. It could also happen if the router has only one connection active - all of the routes it knows about would come from that interface so it would supress all of those routes from going out that interface because of split horizon. > >Hello, > >My router,R3, does not send any rip update.

Re: Console get disconnected
Off the top of my head I think it is the - session-timeout - command that you can set on the line configuration. I seem to remember an exec-timeout also, but can't remember which does what.

Re: IOS Upgrades
I haven't found an easy way to compare IOS versions. I know if you do a search on Cisco's web site by model number and the keywords "feature set" you can come up with returns that will list the feature sets for each of the IOS levels. If you are looking for difference in feature sets at a specific IOS level, then that will do it. You can compre the different sets and what they offer. There isn't any easy way that I know of to compre different levels of IOS other then to print out a copy of each level and look at them side by side. > >Looking to do some upgrades to a few 2500 series routers and need >information in regards to the IP, IP Plus, etc. Does anyone have detailed >information on the differences between the different versions and or know >where this information is kept on the web. > >Thanks, > >EB > > >___ >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] Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com ___ 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: Null route
No. It would only route traffic to null if it couldn't find a route with a more specific match. Traffic is routed to whichever network the destination address falls in that is the closest to the actual destination address. ex - If you had the following routes - 0.0.0.0 via null 0 10.0.0.0/8 via e0 10.20.0.0/16 via e1 If you had a packet destined for 10.20.8.5 it would go out e1 If it was destined for 10.52.23.4 it would go out e0. If it was destined for 9.23.41.1 it would go to null 0 hope that helps mike > > > >Would: > >ip route 0.0.0.0 255.255.255.255 null 0 > >route ALL traffic to null 0? > >___ >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] Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com ___ 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: DHCP Broadcast thru WAN
On the router that is connected to the segment the hosts are on use the following command: ip helper-address x.x.x.x where x.x.x.x is the ip address of your DHCP server.
