Re: CCIE starting pay [7:33899]
A CCIE With no work experience I think most employers would shy away from that! A CCNP, or CCNA possible, but CCIE... Im not sure. That would be like a Brain surgeon with no work experience... WHat would you pay him to operate on your brain Makes you think eh??? I think your best bet is to get a job as a CCNP or CCNA, get a year or two experience (Minimum) then worry about CCIE. Maybe work some other certs in there too, like Unix or maybe Microsoft or something to round you out a bit more and make some opportunities in the market for yourself... Or firewalls, and or something like tripwire etc... My point is, If you have a CCNA, CCNP, CCIE, and 50 other certifications behind your name, and no work experience, poeple are going to know you are a good test taker, but you will still be starting off at the bottom. With a salary range of maybe 30-50k But that CCIE is not going to make it 100k no matter what your cousins brother or whatever told you. All the certifications are for is to take someone who has the experience, and skills, and gives them something they can use as proof of their expertise. It is not for an entry level person to get so they can get a higher start pay... All that does is cheapen the cert. Look at the MCSE. Back when I took my MCSE, that cert gave me credibility. I walked out of every interview with an offer. I could make my own choices. I took my MCSE after several years of workwith Net systems including Novell, IBM OS/2, and Microsoft. It was more of a proof of my skill set. Not a proof I can read Brain Dumps, and hope I will do ok if someone gives me the chance... Now days you mention MCSE, and what goes through your mind??? Thats right Worthless. Now why is that? Its because people with no skills heard of someone who became an MCSE, and started making 70k or whatever... Then that person decided, Hey, I can do that And found Transcenders etc... Became an M CSE, but cant even copy files to a floppy This happened on a large scale, and soon employers were hiring worthless MCSEs, and were getting frustrated... Now, in the IT industry, it has become a low level Cert... TO me that ticks me off. Ive been an MCSE since 96, and mine is prrof of the pudding not a piece of paper... Now, Cisco is becoming the same way. Look at how many people are becoming CCNP...CCNA...etc... How many of those people could configure a medium level network lab without the directions How many could trouble shoot their way out of a paper bag If people dont try to really learn the systems, all certifications will be no better than a 3rd grade diploma! sorry for my soap box, just really feel people take these things the wrong way If people dont wake up, then all of this is for nothing...

Re: CCIE starting pay [7:33899]
Well, more power to you!!! As far as what you should expect An entry level NOC position If you go in with the attitude that you should be at a Senior Level because of the IE, then you will be one of the ones crying about how theres no jobs available... Which ever way you go, I doubt your CCIE will have any more leverage than your CCNP will... Something that might be a good move for you is a latteral move within your ISP. in the AS support or something But it sounds like you are the person the average user calls when they cant get the little E thing on their desktop to do anything If thats your position, get out and move... If you support the companies about their T1, then your in a good starting place... Best of luck, everyone has to start, but Im afraid the CCIE at this stage may hurt you... Heres what I mean You are qualified for entry level... Your Certifications say you are over qualified Your work experience says your under qualified for your certs... What does an employer do? If they have delt with a CCIE before, they probobly wont consider you because they dont have the confidence in you to control their multi million dollar network On the otherside... Your certifications would get you overlooked for the positions you would excel at quickly and allow you to get the experience, because they dont think you would accept any offer for a lower position... So your resume gets dumped Some important things to consider. I would not consider your resume if it had all of that, and all within one year... My first instinct would be BRAIN DUMPS... CHEET SHEETS TRANSCENDERS, and I would throw your resume away Now someone with CCNA, maybe CCNP, but not too much, would get my attention for a good paying entry to mid level position CCIE is upper level position Cant put you in charge of my team of engineers with experience levels ranging from 2-10 years when you have 0-1 No one would folllow you. It would not be a good team anymore These are things beyond the technical aspect that management must face. Just think about it.. Im not trying to keep you from succeding, just trying to keep you from hurting yourself... Its like the small company that saves up their money for a Super Bowl Ad...

Re: Home Network [7:38818]
You have several choices... Choice 1 (low budget...) have 2 nics in the 200 server... One nic goes to your DSL modem, one to a switch Setup NAT for translation between them (already included in 2000 server...) If your 200 Serv er is the AD Server, and your clients are part of the 2000 domain, then your 2000 server must be the DNS server... Go into the DNS properties, make sure there is no folder in the root called root ( a yellow folder named . ((Yes called dot but with a . not the words))) if this exists, simply delete it... Then go into the properties of DNS and check enable forwarding, and set the DNS of your ISP. This will keep your DNS environment intact for Active directory, and still allow everyone to connect to websites... Option 2, buy a DSL router $99.99 with 4 switchports at best buy... And follow the picture on the box for setup... do the same thing for the DNS info I supplied, and make sure your clients are using your 2000 DNS and let the 2000 DNS server forward requests out of the domain...

Well, one specific example would be for the 75xx series of Cisco router that uses the VIP cards. If you attach the VIP card (from enable mode, do a if-con ) and then run sh proc cpu from there, and you will see that alot of the memory is getting tied up with routing lookups and interrupt requests. Add a few of these to a router and you will suffer from latency due to not enough memory to do lookups. I am not a big fan of VIP cards in practice because it seems like on a decent sized network, one will crash per week. But that is a specific Cisco example.

OT: Should i take up this Job at Cisco : Juniper vs Cisco
I work with both Ciscos and Junipers daily. Junipers have some very nice features that Ciscos dont have. Anyone that has issued the monitor command on a Juniper knows what I am talking about. The OS seems to be a combination of the Cisco IOS and Unix, which is nice as well. I myself prefer the Cisco CLI, probably out of habit. Please don't talk about the virtues of CEF when I can't even view the whole cef table without causing my router to crash. Not that there are too many instances when you *need* to view the whole table, but the option is nice to have. My company tested both oc192 devices, and the Cisco didn't do better. Both companies have good support teams. The bottom line is, do what you think is best for yourself. If working for a smaller company is important to you, and it sounded to me like it was, the choice is clear.

Layer 3 Switching [7:1222]
I am trying to find out about switching on the CCIE lab exam, is there a particular focus on layer 2 using the set commands, or is it a mix of both? I am just trying to get an overview of what I need to pass the test, should I buy the RSM for the Catalyst 500, or should I save my money. Any help would be appreciated.

Switching on the CCIE Lab Exam [7:1296]
I asked this question before, and someone sent some helpful info, but I am looking for something more specific. I know the 5000 series is the switch used in the lab, but is the focus more on layer 2 or layer 3?

CEF also allows you choose whether to load balance per packet or per destination. Fast switching only allows per destination.

RE: point to point T1 troubleshooting [7:4987]
Park, if you look at the output you can see that the last time you cleared the counters on the interface was approximately 18 hours ago: Last clearing of "show interface" counters 18:08:32 Since that time you have had: 8940 input errors, 1913 CRC, 0 frame, 6028 overrun, 0 ignored, 999 abort 3438 interface resets This would indicate that there is a problem with the T1 line or the cabling between the router(s) and their interface with the T1 whether it be through a V.35 into a CSU, or a straight cable into the NIU or smartjack. I would recommend calling the circuit into the carrier that provides it and asking them to test the line. In my experience about 97% of the time it is a carrier issue such as a bad cross connect in the CO. It is also possible, although very unlikely, that the router interface itself has a problem but you will probably find that this is a carrier issue and that it can be repaired by them. -Original Message- From: park jeongwoo To: [EMAIL PROTECTED] Sent: 5/18/01 11:04 AM Subject: point to point T1 troubleshooting [7:4987] HI all Have anyone troubleshooted PPP TI before? it is leased line and ppp encapsulation.

I think that they are not, the reason is that it is a waste of resources. Why send discovery packets out an interface that you have not specified as participating in the routing process anyway.

RE: Variance command? calculating variance????????? [7:7239]
You should look at the metrics for each of the routes, and lets say that the 128K link is for example 1000, the 512K link is 500, and the 1024K link is 250. Variance defines a multiplier by which a metric may differ, or vary, from the metric of the lowest cost route. So if you specify the variance as 4: 4 * 250 (the lowest cost in my example above)= 1000 This means that any route having a metric up to and including 1000 will be used in unequal cost load balancing (as long as certain other rules are met). Please don't credit me with the whole explanation, I got some of it out of the Cisco Press book Routing TCP/IP Vol. 1 by Jeff Doyle. Hope this helps.

RE: Route Updates and Fast Switching Cache [7:8110]
John, my understanding is that the router will continue to use the previously cached route until such time as the cache for that route is aged as invalid. 1/20th of the cache is aged randomly every one minute, unless there is less than 200K of available memory, in which case 1/5th of the cache is aged every minute. After it has aged the router will then process switch a packet to that destination since it has no cache entry, see that there are now 2 routes to the destination and re-build the cache with both paths, performing per-destination balancing as that is the only available balancing method with fast switching. I have found that in a lab environment the aging will happen very quickly because you have very few entries, and you will probably find that it is a minute or less before both routes are being used. You can see this if you want by configuring 2 routers with 2 different equal cost paths to each other, but only having one in the routing table, ie shut down one interface. Turn on ICMP debugging and ping the other router, then bring the other interface up and do another ping. You will probably find that the router will send all 5 pings out one interface, and then the next 5 pings will be sent out the other interface. You can also look at this link http://www.cisco.com/warp/public/105/20.html#3 to find some really interesting info on the different switching methods. Hope this helps. -Original Message- From: John Neiberger [mailto:[EMAIL PROTECTED]] Sent: Tuesday, June 12, 2001 1:18 AM To: [EMAIL PROTECTED] Subject: Route Updates and Fast Switching Cache [7:8110] After reading a practice test question and answer I'm confused about the operation of fast switching, specifically when a route has already been cached when a new equal-cost route is learned via a different interface. For example: Route A learns of 192.168.1.0/24 via e0 with a metric of 1000. Fast switching is enabled so this route is cached. Then the router learns of 192.168.1.0/24 with a metric of 1000 via e1. My thinking is that the cache would be invalidated and recreated with two entries but the test engine answer stated that routing would not change because the route was cached and the cache would not be invalidated. Any thoughts? I'd test this myself but at the moment I only have two routers at home. Do any of you have any experience with this?

RE: bandwidth [7:8623]
If it is a WIC1DSU-T1 you can do a show service-module serial [interface number] and look at how many timeslots the fraction has. If the CSU is external you can look at how many timeslots are configured on the CSU itself. This of course does not indicate your CIR, which may be lower than the actual line speed, you can get that from your service provider. Hope this helps.

Variance in IGRP and EIGRP [7:9754]
I am working with a lab setup and have a question on variance. I know what the variance does, but it does not work with all routes. I have the variance set to the maximum on all routers (128), but only certain unequal routes get placed in the routing table. If I shut down the link on one of the routers the higher metric routes get installed, but only in the event of a link failure. I know there are some rules that govern the installation of a route once the variance is configured, if someone has a concise explanation of what they are and how they work it would be greatly appreciated. Thanks in advance.

Variance in IGRP and EIGRP [7:9756]
Please disregard my earlier question, I found the answer. Apparently for a route to be installed for unequal cost load balancing the routes metric must still be lower that the routers feasible distance to the destination, and that is why I am only seeing the routes in the event of a link failure.

RE: Trace result assistance [7:10398]
It appears that there is a problem at the 164.220.193.66 address. 164.220.193.65 is sending the packet to it, and 164.220.193.66 is sending them back. This problem usually appears when the 164.220.193.66 address does not have a route to the destination, and 164.220.193.65 is set as its default gateway, so it just sends the traffic back to its default gateway because it does not have a route to the destination. There can be alot of reasons for this, but I would start at the 164.220.193.66 address. Hope this helps.

RE: Loop Up [7:34804]
A CSU has the ability to loop up a far end CSU or smartjack. When the CSU sends a loop up, the remote CSU or smartjack will go into loop, and you can run testing patterns to that loop. It is used to test the end to end connectivity of a circuit. For instance, lets say you have the following: CPE--CSU(A)-Smartjack(A)---CO--CO---Smartjack(B) CSU(B)--CPE If there is no connectivity, you could go to CSU(A) and send a loop code to Smartjack(B) or CSU(B). You would then run a test pattern, say 3:24, to the loop. If the test pattern runs clean, with no errors, then you know that you have a good circuit from one end to the other, and the problem may be with the CPE. On the other hand, if you try to loop the CSU and you can't, then you would try to loop the Smartjack and run to that loop. If you can run clean you know the problem lies somewhere after the Smartjack, if you can't then you would call the carrier and ask them to find out what is wrong with the circuit.

RE: Problem telnetting into router with NAT enabled [7:35634]
To be honest, I don't have a definitive answer. I did hear from someone on the list that this is because NAT is often used as a security tool as well as a method to save public IP addresses, so Cisco decided that it would be a good idea to only allow telnet if you did this additional mapping, I think Ejay was the one who told me that. Theoretically there is no reason you shouldn't be able to telnet right to the serial interface's IP address. As far as the extendable command, there is a description from CCO at the bottom, I always use it at the end of a translation, unless I know that I will not be mapping that local inside IP address to any other IP. If you don't use the keyword, you will not be able to map the private IP address to more that one public IP address, this is useful for situations where you have 2 providers, one as a backup lets say, and you want your mail server to be mapped to one IP from the primary provider and one IP from the secondary provider.

ISIS filtering, redistribution, etc. [7:36580]
Does anyone know of a good link that I can go to to find information on filtering and redistribution in ISIS? The only thing that I can find is a note in the archives stating that you have to use a clns access-group to filter, but it doesn't say how to implement it and I am not having any luck on CCO. I have routers running 12.1 and routers running 12.0, on the 12.0 routers there is a distribute list command, but it doesn't seem to work when applied, and on the 12.1 routers it isn't even available. If anyone could help me out I would appreciate it, I am stuck at this point, thanks.

RE: ISIS filtering, redistribution, etc. [7:36580]
That would probably work for the redistribution, I will try it out. I was actually looking more for a method like the inbound distribute list that you can use with OSPF. In 12.0 there is a distribute list command that can be entered under the ISIS process, but it does not filter the specified networks, and in 12.1 it is no longer available. I am trying to make it so that routes that are native to the ISIS domain/area (ie interfaces with "ip router isis" enabled) can be filtered on the receiving router, haven't found a way to do that yet. Thank you for your response. Anyone out there work for a company that uses ISIS? Any wisdom to share?

However, I think I can help you out. Try using a route map instead of the distribute list. Something like: 'redistribute ospf 100 metric 100 metric-type internal route-map FILTER' and then: 'access list 1 deny 10.0.1.0 0.0.0.255' 'access list 1 permit any' and finally: 'route-map FILTER permit 10' 'match ip address 1' I wish I could claim that this was a flash of brilliance. Truth is, it was one of the labs in the Link State CIM by Cisco Press. Let us know how it works out.

RE: basic OSPF questions [7:37142]
There is a reason for the first one that I have seen. If for some reason you are using your loopback subnet for a NAT pool, and the NAT pool requires more than one global IP address, you can assign a /29 (or whatever) to the loopback and use that whole range for the NAT pool. That is one instance in which you may want to advertise more than a host route for your loopback. You could have loopback 1 as the RID, and loopback 2 assigned the /29 for NAT, loopback 2 would have the "ip ospf network point-to-point" command to advertise the /29. -Original Message- From: Priscilla Oppenheimer [mailto:[EMAIL PROTECTED]] Sent: Monday, March 04, 2002 2:48 PM To: [EMAIL PROTECTED] Subject: Re: basic OSPF questions [7:37142] At 08:59 AM 3/4/02, bergenpeak wrote: >1) A loopback address is normally advertised by OSPF as a host route. >The command "ip ospf network point-to-point" enables one to specify >that the interface should be advertised as a subnet route.

"On point-to-point networks, if the neighbor's IP address is known, set the Link ID of the Type 3 link to the neighbor's IP address, and the Link Data to the mask 0x (indicating a host route) If a subnet has been assigned to the point-to-point link, set the Link ID of the Type 3 link to the subnet's IP address, and the Link Data to the subnet's mask..." >2) Must a link cost be the same on for all routers that share the >link?

I think so, but I've never thought about the database synchronization issues associated with a router that is a neighbor to many routers. My guess is that it can only be in the exchange state with one router at a time. Otherwise it would be exchanging database info with one router as the info was being updated by another router?? >Thus, a router goes into Exchange state, sends all DDPs it knows about, >then goes into Loading state, where it issues LSRs for LSAs it wants >more >details on?

I see your point, unfortunately I can't test it right now.

[7:37318] Well, let's see it from a different angle. Normally, the left byte is 21 hex, which is 0011 binary. Here bit 8 and 13 are set (bits 0 thru 7 are in the right byte). This is what I normally have, and I can use BREAK, so it must be enabled. I also use 9600 as the baud rate, so that makes sense too. If you set bit 11, the baud rate will now change to 4800. That gives a binary pattern of 00101001, which is 29 hex, which is what your left hex (most significant byte) is set to. I don't know where you got the calculator, but I would trust Cisco's documentation (which is what I am refering to) before I would trust someone's homemade application tool. A good way to find out, would be to disable bit 8 (set it to 0) and try to use BREAK. Then try to change the values of bit 11 and 12 and see what baud rate you have to configure to talk with the router. That's not only a good way to find out what's what, but a good exercise for your studies. Hth, Ole ~~~ Ole Drews Jensen Systems Network Manager CCNP, MCSE, MCP+I RWR Enterprises, Inc.

RE: OSPF with Riverstone.(RS3000) [7:37523]
Do you have the ability to use this command? ospf set interface blah state disable I don't have a box that is not in production to test this on, I would be curious to see if the router still announces the network but just does not send hello's. I am also running an older version of code on this box so you may not be able to use this command. Also, why is it that you are adding all interfaces to the backbone area? Does it make sense for you to only add those interfaces you want to the backbone area and then redistribute connected networks for those interfaces you don't want hellos sent on, or are there just too many interfaces to make adding only certain ones to the backbone efficient? ~-Original Message- ~From: Sean Kim [mailto:[EMAIL PROTECTED]] ~Sent: Thursday, March 07, 2002 7:18 PM ~To: [EMAIL PROTECTED] ~Subject: Re: OSPF with Riverstone.(RS3000) [7:37523] ~ ~ ~Thank you for your feed back Peter, ~I also tried to add ALL the interface by using below command ~ ~ospf add interface all to-area backbone ~ ~And then tried to set some of the interfaces passive, individually. ~ ~ ospf set interface xxx.xxx.xxx.xxx passive ~ ~but this failed, so I tried using interface name. ~ ~ospf set interface InterfaceName passive. ~ ~But this also gave me the same error meesage that the interface ~is not recognized. ~I tried Riverstone Homepages and tried to get more info, ~but with no avail. ~ ~Would anybody like to share his/her knowledge? ~ ~ ~ ~ ~ ~Never touched a Riverstone box before, but your summary-range certainly ~looks much more like type 3 summarizing rather that adding ~interfaces to ~the ospf process. ~ ~ ~At 01:27 AM 3/7/2002 -0500, you wrote: ~>Hello everybody, ~> ~>I know this doesn`t have much to do with Cisco, ~>but if anyone would like to share his/her knowledge, ~>I would be very grateful. ~>Has anyone worked with Riverstone RS3000 before? ~>I have set up OSPF backbone area on RS 3000, ~> ~>ospf create area backbone ~> ~>Then I wanted all the ports to autumatically belong to the ~backbone area. ~>So I tried below. ~> ~>ospf add summary-range xxx.xxx.xxx.xxx./xx to-area backbone ~> ~>Then I wanted some of the ports to be set passive so that ~>networks that are connected to the ports and my backbone area ~>wouldn`t exchange routing info. ~> ~>ospf set interface xxx.xxx.xxx.xxx passive ~> ~>I thought this would be sufficient but I got an error message ~saying that, ~>the system doesn`t recognize the interface xxx.xxx.xxx.xxx. ~>I DID try to add individual interface to backbone area and ~>set them passive individually then it worked. ~>But as more network is attached to the RS3000. ~>This will be alot of work. ~> ~>Does anyone have any idea? ~> ~>Thank you very much in advance. ~> ~>sean k` ~ ~ ~ ~ ~Report misconduct ~and Nondisclosure violations to [EMAIL PROTECTED] ~ Message Posted at: http://www.groupstudy.com/form/read.php?f=7&i=37614&t=37523 -- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
RE: NAT concepts [7:37815]
Found this on CCO, I assume the prefix would be the same concept, a sanity
check. Link is at the bottom, HTH.
Q. Why do I need to specify a subnet mask when configuring a NAT address
pool?
A. The subnet mask is used to sanity-check the addresses allocated from the
pool (so we don't allocate the subnet broadcast address, for example). The
subnet mask must match the size of the subnet into which you are
translating.

Re: Rack [7:38796]
I use music racks... they are designed for amps, and mixers etc... usually
for DJs. They have a good counterbalance system, and are on rollers... They
come in 2 standards... europe and american... the american standard is the
same peg spacing as network equipment. and they look sharp
They are under 100.00 usually and stand about 4.5 feet or so.

Q2 A large amount of IP fragmentation is occuring on VLAN2.Tune DLSW so that the IP fragmentation will not occur as soon Q3. Configure Rx such that workstations on Vlan30 can dynamically locate their default gways.They are not using DHCP?? (Page 1167) Q4 On R2, create a SAP filter blocking all saps starting with "fake" Q5.Configure VLan30 such that saps are advertised onlu when new server comes online? Q6.Configure R1 as an NTP server. Configure peer asssociation such that R4 synchronize with R1. When R4 synchronized allow R2 and R3 to synchronize with R4. If R4 is not Synchronized with R1, R2 and R3 also should not synchronize?? Q7. COnfigure R1 so that when the user Unnamed logs into the router, its immdediately put in enable mode.(pg 1177) Hope u will enjoy... Thanks for u help.

RE: Multi Link PPP ( MLP ) questions [7:39961]
Try "no peer neighbor-route" on the multilink interfaces, that should get rid of your /32. It is part of ppp, when the negotiation takes place a /32 is input for the other side. I do not use multilink unless it cannot be avoided, I have had issues that make the use of it unappealing. Is there any reason you can't just use CEF or fast switching and have multiple routes to the spokes, one down each T1? If you are using CEF, it is more efficient to do it this way because there is no overhead. In multilink each packet gets an additional 4 byte (I think) header. By the way, I believe that the virtual template method is outdated and no longer used. You don't need it anyway, just the multilink interface and the serials specified as part of it.

You should be able to use CEF on anything above or equal to a 2600, and maybe the 1600's? Not positive. There are no issues that I know of as far as per-packet versus per-destination, you can define on a per interface basis that the load sharing is to be per-packet with "ip load-sharing per-packet", or per-destination with "ip load-sharing per-destination". It works very well.

Modifying files in flash [7:11202]
Ok, this question may be a little bit strange but here goes. Lets say that you have a file in flash: called OSPF. It is a file you saved of a configuration. Now I know that you can tftp the image to somewhere and then modify it and load it back up, and I know you can use the more command to view the file. Is there a way to modify the file from the router without making it active? I want to modify the file and then copy it into the running config without leaving the router. No reason, just wondering if anyone knows of a way. Thanks.

RE: Output of sh ip route connected [7:11266]
The IP address / mask combination would tell you. Since the address/mask was 10.20.1.104/30, you know that this is not a valid host because a network with a /30 mask always begins on a number that is a multiple of 4. The /30 indicates that there are 2 valid hosts, 10.20.1.105 or 10.20.1.106, 10.20.1.104 identifies the network (a multiple of 4), and 10.20.1.107 is the broadcast address. So the next available network is 10.20.1.108 and if it has a /30 mask also the valid hosts are 10.20.1.109 and 10.20.1.110, with 10.20.1.111 as the broadcast address.

RE: Packet Sizes [7:12826]
Thank you to all who replied to this post. I do have another question for you. When the packet is sent to layer 2 for encapsulation and transmission, if it is Ethernet, an Ethernet header is placed on and the frame is transmitted. As far as I know the only requirement is that the frame must end on a 32 bit boundary, must be at least 64 bytes, and is not padded further. So that if the packet is 700 bytes, and is encapsulated in an Ethernet frame, the total would be approximately 726 bytes. Is this correct? -Original Message- From: Priscilla Oppenheimer [mailto:[EMAIL PROTECTED]] Sent: Wednesday, July 18, 2001 2:52 PM To: [EMAIL PROTECTED] Subject: Re: Packet Sizes [7:12826] FTP generally uses a full-size packet: 1500 bytes on Ethernet, not counting the header, CRC, preamble, inter-frame gap, or any VLAN or MPLS tagging. HTTP does not use a full-size packet usually. You would think it would, but it tends to use a 500-600 byte packet size. Using a shorter packet size improves perceived performance because the screen can show partial data while more data is en route. ICMP depends on what you are doing and what parameters you use. Most error or warning messages would be very short, probably 64 bytes or so. If it's ICMP echo (ping), then the user can specify the number of bytes. TFTP sends data in 512 byte blocks. Add the 8-byte UDP and 20-byte IP header. For all of these examples, there may be additional shorter packets for ACKs and other overhead.

Multiple OSPF areas on the same router [7:13108]
Lets say you have a router with 6 DS3s, has anyone ever heard that it is not a good practice to have each DS3 be its own area? I was talking to someone and they said that it may not be a good idea to have multiple areas on the same router, but I have never heard that. Thanks.

RE: OSPF [7:13105]
Jeff Doyles Routing TCP/IP Volume 1 is a great book as far as configuration, theory and troubleshooting. It gets into serious detail. -Original Message- From: mike rose [mailto:[EMAIL PROTECTED]] Sent: Friday, July 20, 2001 1:08 PM To: [EMAIL PROTECTED] Subject: OSPF [7:13105] Hello all Is there a book out there (besides Cisco's BSCN)that will break down OSPF in all its glory to me?
