Re: Difference between Directed Boradcast and Mulitcast
an aspect i did not notice to be covered in the response found below is the following: it appears to me that multicast technology incorporates control of traffic distribution into the addressing scheme: all multicast-rfc-compliant-devices will forward traffic to multiple hosts if the destination address warrants it. it also appears to me that directed broadcast is dependent upon the configuration of each device in the potential path of a given wayward ip packet: if a device is configured to forward directed broadcast, the packet ambles on. if not, it expires in the fashion of most packets, within the confines of the circuitry of the device that last received the packet. so, with a directed broadcast, your device is indiscriminately forwarding multiple-destination traffic on a per-interface-basis, while a multicast implementation allows for some means of control as might be implemented from the source end. i'd humbly ask that members of the group advise everyone if it is the case that, as usual, i'm way off base.

A multicast is an IP address 224.x.x.x/4 (224-239.x.x.x) while a directed broadcast can be to any class A-B-C subnet; the directed broadcast having all ones in the host part of the subnet address. A "directed" broadcast is one which "may" be routed. Similarly, multicasts "may" be routed, and in the absence of any other parameters it will be flooded across all router interfaces, while a directed broadcast goes to a specific interface. At the layer 2 level, broadcasts use the all ones MAC address of FF-FF-FF-FF-FF-FF. Multicasts have the second hex digit "odd" so that the "little-endian" nature of the ethernet results in the low-order bit of the second hex digit being transmitted first. The NIC hardware will detect this and signal an interrupt in anticipation of a broadcast. Smarter NICs will continue to receive and match the source MAC (if not a broadcast) with designated multicast addresses it has been told are "interesting". There is also an interplay between multicast MACs and IPs (left as an exercise for the reader). For the first three bytes of the MAC, the vendor ID (in the first three bytes) is preserved but the low order bit of the first byte is set, making it odd (the second hex digit). For example, an HP manufactured NIC might have an 08-00-09 prefix; but HP specific multicasts will have an 09-00-09 prefix.

RE: "Token Ring in home lab" questions
I have limited exposure with TR (but more to come with my new job) but I do know a little. I believe TR uses pins 3, 4, 5, and 6 pins. Standard cat 5 will work cause the pins in the middle are lined up. RO(ring out)is where you connect the MAU or MSAU to the RI(ring in) of the next MAU/MSAU.

Re: problems configuring a 5500 chasis please help
The RSM can be placed in any slot except for 1 (reserved for Supervisor) and 13 (reserved for ASP). If you plan on using the ATM cell switching backplane I would recommend placing the RSM in an upper slot (9-12 are cell backplane capable). The RSM will only communicate with a single 1.2 Gbps backplane of the 3 enabled with the Phoenix ASIC, so it doesn't matter which slot of the 2-12 it is placed in. The RSM will down an interface if no physical port in the logical VLAN is active. This means that the switch must be configured and the port must be active. As noted previously, this might be the source of the problem. Using the 'show interface' command will resolve this consideration. I have seen issues with older versions of code and mis-matched speed/duplex cause the RSM to fail to up/up. I'd recommend 4.5.5 at a minimum, and 12.0.9 for the RSM. Look at the ports also - use the switch to verify that it can see the 'connected' switch at Layer 2 - the RSM will not see things correctly if the Supervisor does not. --- fmxiao <[EMAIL PROTECTED]> wrote: > We've always put the RSM in Slot 4... > > > "Mark Krysinski" <[EMAIL PROTECTED]> wrote in > message > [EMAIL PROTECTED]">news:[EMAIL PROTECTED]... > > Are you sure you can plug the RSM into slot #2.

Humm... interesting question. >From one point of view... What should be tested (or not tested): In over 10 years of IT work I have only ran across AppleTalk once, so drop AppleTalk (which they are doing). In the same time frame I have only ran across one IPX network that wasn't either in the process of being converted to 100BaseT or was only being used in the DC to connect to a Novell server that was a file server which had it's drives mapped to NT drives. So IPX should take a big back seat to IP. TR, well personally I like it, but again I have only seen one network with TR that wasn't planned to be changed to 100BaseT. Come to think of it, they announced the upgrade a couple of months after I left there. So TR should also be in the back seat. Bridging, humm... well in some respects it is rarely used in the networks I have seen, mostly to get to SNA servers. But then again you had better know your IRB pretty well with all of the L3 switching that companies are being sold these days. L3 switching, better know that pretty well. There are just too many companies being sold L3 that it had better take a bigger role in the lab. The R/S written and lab should take on more of the service provider element. I am not saying that the new SP track should be rolled into the RS track. But with outsourcing and the Internet with VPN, dial and the like taking a bigger and bigger role in most companies, better know your ATM, dial, VPN, BGP, etc, etc. The same can be said for security. Not having taken the lab, I can not really say as to how IPX, TR, or bridging is tested. It could be that it is tested as a primary thing and not as a secondary, e.g. "well looks like we are going to have to deal with that TR segment over rather we want to or not". The same could be said for ATM, maybe it should be a primary and not a secondary.

The "jam" signal is asserted after a collision detection and most commonly simply continues to transmit the data in the collided packet for another 64 bits. The flow control method of "assert carrier beyond the length of the packet" is entirely different -- it is sending the 802.3 preamble of 0x05 continuously without the trailing 8th byte 0xD5 (I'm pulling this from my somewhat foggy memory on the values, but the preamble is 7 bytes of "something" followed by a byte signalling the start-of-packet, so don't shoot me if my values aren't correct). As for Cisco documentation, and some others, they refer to this method of flow control as "back pressure". It has the advantage of not propagating a collision (as in the intentional collision method of flow control) as it will not interfere with any other hub/switch/NIC on the network other than causing a transmit deferral. But as I had said earlier, 10Mb NICs have logic to detect carrier (or preamble) being asserted longer than the MTU plus propagation delay and consider this to be "jabber". This was not carried forward to 100Mb or 1Gb NICs. But I will concur on your statement: > The only reason I took it to any depth was the fact that other than duplex > mismatches a lot of people getting into this field (reading these posts) > haven't ever been exposed to such nuances. I value real world experience much more than some CC** acronym after your signature.

Re: Re: 7505 Reboots randomly Please HELP
Follow up on this topic. A couple of things I did not glean from your post was whether this router was a new (to you) install, or whether it was previously working and you recently upgraded the code. If the case is the latter, I am in strong agreement with Jim Dixon that the likely culprit in the process is probably the version of code you are running. Specifically, did you have stable code on this router and upgrade to a newer 12.x image whereby the problems resulted? If so, it is a very strong indicator that the problem is with your software, not the hardware. If you do have CCO access, you may want to consider putting some very stable GD type code, such as 11.2(17) and see if that works. If so, and the 12.x code you have does not work, then you will need to do some experimentation to see what code is stable for the hardware you have and the features you *need*.

Re: "Token Ring in home lab" questions
Lori- it's usually very cheap & easy. Funny thing (from the Ebay prices) it appears people are steering clear of Token Ring. OK- you need a MAU (which you have), 2 cables (DB9 to that funny IBM connector), or 1 cable standard cable & 1 for the NIC (which can either be RJ45 or DB9). Your connection is made on the numbered ports. The R0 & R1 are for daisy chaining the MAU's together. http://www.cisco.com/univercd/cc/td/doc/product/core/cis7505/ipicg/ipicgtrp. htm#xtocid40785 Here's the shpeal on the cables... Once you have two stations (I use a 2512 & a 4000), just set the IP's & the ring speed (4 or 16)... you should hear the MAU clicking & your off to the races.

Re: crossover or straight cable?
Would it not depend on what you are connecting to. For example from a switch port to another switch port both the ports would be the same signalling therefore a cross-over would be required. From a switch to a router the ports a different a straight cable should do fine. What we a trying to achieve is a transmit wire connecting to a recieve. If this does not occur in the ports then we must do it in the cable (cross-over cable). A transmit must connect to a receive for a circuit to work. Lets say from a switch pins 1 RD+; 2 RD-; 3 TD+; 6 TD- Pins 4, 5, 7 & 8 are not used in ethernet. If they were connecting to another switch we would need a crossover to have pin 1 RD+ connecting to 3 TD+ In a router or PC the connetions are 1 TD+; 2 TD-; 3 RD+; 6RD- A straigh cable would connect pin 1 (switch) RD+ to pin 1 (adaptor) TD+ and so on. A long winded Teunis explanation but this I hope helps.

RE: EIGRP problem
I may have missed some of the earlier thread but what would be beneficial is show version from the routers and show run (that should be a given anytime someone posts a problem with a production network). Not having another other information, it sounds like a bug. The reason I say it sounds like a bug is because the default being redistributed by the 4000 came back as soon as a clear ip route * was done and the problem comes back after a few days. Had the problem been something related to a change in the network itself, the default route should have come back by itself. And if that situation hadn't changed the default route should have never come back after clearing the routes, the situation should have remained the same.

Re: EIGRP problem
Without having all the configs and info, I'll take a shot at this. Since this is only happening at some sites you may want to look at utilization on the frame links. If your utilization is so high that you are missing eigrp hellos, the routing protocol may decide that the route is not there and the router will use the next best route in the routing table which would be the floating static that you have configured for DDR backup. If the above is not the case, then perhaps you have a combination of two problems: First, you do not have correct bandwidth statements on the interfaces and second you are not being specific enough when you define interesting traffic to bring up the backup link. What you want to do is write an access list that will deny eigrp but permit everything else. This will be used in the dialer list then applied to the BRI interface with the 'dialer-group' command. This only causes eigrp to NOT bring up the link but will permit eigrp traffic once the link is up. Another thing to be careful of is that if the frame link is up and the isdn line does become active, you don't want that remote site to become a transit path to the rest of the network. You should use distribute-lists at the remote sites to only advertise networks behind the remote routers. Anyway, just my humble opinion without all the info. Hope it helps. If not and you are able to provide additional information, I would be glad to try to help more. -dennis Jim Bond wrote: > Hello, > > We have 4000 router and 5200 router at central office, > 2500 routers and 3640 routers at branch office. 4000 > and 2500s are connected with frame relay, 5200 and > 3640s are connected with ISDN backup.

Makeeda "DS1 (Digital Service Level 1) 544Mb/s. Another name for a T1. The specific difference between a DS1 and a T1 is that the T1 is on copper and comes with a -135-V battery voltage, and the DS1 is a dry circuit, on copper or fiber-optic lines, with no battery voltage. Other than that, they are the same. A DS1 has a total bandwidth or transmission speed of 1.544 Mb/s. The 1.544 Mb/s is divided into 24 64Kb/s channels. A DS1 (T1) is available in several different packages that offer different line formats and framing formats. The package that a customer requests from a phone company depends on what they want to use the DS1 for and what kind of equipment they have. Telecommunications customers use DS1 circuits as private lines to connect data devices from one geographical place to another or to transport large amounts of dial tone to the premises. DS1 circuits are also used to connect directly to a long-distance company for broadband WAN service. Telecommunications companies also use DS1 (they are T1 circuits within their own network) circuits to provide more telephone service where a shortage of twisted pairs is available. DS3 (Digital Service Level 3) 44.736Mb/s. A DS3 is a circuit that is provided to customers by telephone companies. It is a transport for 28 T1 circuits, which adds up to 672 DS0 circuits (voice channels). Telecommunications customers use DS3 circuits as private lines to connect data devices from one geographical place to another or to transport large amounts of dial tone to the premises. DS3 circuits are also used to connect directly to a long-distance company for broadband WAN service.

Re: So what SHOULD a CCIE know?
Howard: I agree and disagree. I think you are right on the money with your observations, but only as they pertain to the R/S CCIE. I think Cisco should (and is beginning to) address the more specialized knowledge areas by offering multiple certification tracks. (eg. SNA, ISP, Voice???). Once these other tracks really catch hold, I think you will see more people moving away from the R/S tracks and into the areas of specialized knowledge and experience required for their particular jobs, as you so deftly stated.

Hi all, I am in the process of configuration a bunch of routers to do ISDN dial backup. Has any body worked with Dialer Watch on a router running OSPF? I know that some Cisco document says that Dialer Watch is only supported in EIGRP and IGRP. But others say any Dynamic routing protocols. Also, has any one used the IP OSPF Demand Circuit? This option is suppose to control the types of LSAs that are sent across the dial line. It reduces the amount of Access-list that is needed to monitor the traffic. Basically, I am using 4 BRIs in a Dialer Interface with ip unnumbered Loopback0. Then, I will be using Dialer Watch to trigger the ISDN calls and run OSPF Demand Circuit to control packed over the dial link. Defaulting back to the serial link will be done based on OSPF cost statement once the link comes back. Does this sound like it's feasible or is it too much to handle? Any help will be greatly appreciated!

RE: T3 and Ds3
Hope this helps to clarify things. Makeeda "DS1 (Digital Service Level 1) 544Mb/s. Another name for a T1. The specific difference between a DS1 and a T1 is that the T1 is on copper and comes with a 135-V battery voltage, and the DS1 is a dry circuit, on copper or fiber-optic lines, with no battery voltage. Other than that, they are the same. A DS1 has a total bandwidth or transmission speed of 1.544 Mb/s. The 1.544 Mb/s is divided into 24 64Kb/s channels. A DS1 (T1) is available in several different packages that offer different line formats and framing formats. The package that a customer requests from a phone company depends on what they want to use the DS1 for and what kind of equipment they have. Telecommunications customers use DS1 circuits as private lines to connect data devices from one geographical place to another or to transport large amounts of dial tone to the premises. DS1 circuits are also used to connect directly to a long-distance company for broadband WAN service. Telecommunications companies also use DS1 (they are T1 circuits within their own network) circuits to provide more telephone service where a shortage of twisted pairs is available. DS3 (Digital Service Level 3) 44.736Mb/s. A DS3 is a circuit that is provided to customers by telephone companies. It is a transport for 28 T1 circuits, which adds up to 672 DS0 circuits (voice channels). Telecommunications customers use DS3 circuits as private lines to connect data devices from one geographical place to another or to transport large amounts of dial tone to the premises. DS3 circuits are also used to connect directly to a long-distance company for broadband WAN service. Telecommunications companies also use DS3 circuits to provide more telephone service where a shortage of twisted pairs is in their cable plant. Sometimes it is less expensive for a telephone company to install the DS3 electronics in areas, rather than long feeds of large twisted copper-pair cables." -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of John Hardman Sent: Wednesday, December 27, 2000 8:18 PM To: [EMAIL PROTECTED] Subject: Re: T3 and Ds3 Hi Yep terminology, typically T1, T3 in the telco world imply the capabillity to carry voice and/or data.

EIGRP problem
Hello, We have 4000 router and 5200 router at central office, 2500 routers and 3640 routers at branch office. 4000 and 2500s are connected with frame relay, 5200 and 3640s are connected with ISDN backup. Eigrp is the only protocol. We have a default route from 4000 and it got advertised on 2500s and 3640s as AD /170. We also configure a default route on 3640s with AD /200 so in case frame is down, /200 default route will take over and then can bring up ISDN. The problem is sometimes when frame is ok, 3640 router default route changes to AD /200 and hence brings up ISDN backup (3640 also serves as RAS server). When I do "clear ip route", the AD /170 default route will come back again, then some days later, it'll get replaced by the AD /200 one. We use the same IOS on all routers but this only happened on some branch offices, not all of them. Any idea what wrong it is? Thanks in advance. Jim __ Do You Yahoo!? Yahoo!

RE: So what SHOULD a CCIE know?
It is obvious that with the explosion of the Internet that networks and networking, in general, are moving to a more unified approach. We are seeing legacy protocols that could not stand the test of time give way and die in the face of TCP/IP. All of this is good news for CCIE's among others. The more things standardize on tried and true open standards, the better off our jobs will be, not to mention the experience of the customers we service. Imagine a world with no Appletalk, IPX, SNA, LAT, etc. Imagine that there are a few base protocols like TCP/IP working in tandem with Routing Protocols like OSPF and BGP. I beleive that when that day arrives, the CCIE should be a true expert in the pared down world wide standards that emerge as the dominant players. The less needless complexity that we need to grapple with, the better we can become and hone our skills to the expert level.

Quick Survey: Con or Aux?
Today I got into a discussion about the appropriate place to connect a router for remote management of routers. If you plug it into a console port, you have the ability to reset the router and recover the password. However, if you get disconnected, you leave a session open, causing a security problem. Although you can use exec-timeout, it still can make it difficult to reconnect to it if you lose a connection.

On the MAU, there are two ports that are labeled RO and RI with small push button switches next to them to enable or disable "wrap". What are these for? Any information would be appreciated.

ISDN Dialer Watch / OSPF Demand Circuit
Hi all, I am in the process of configuration a bunch of routers to do ISDN dial backup. Has any body worked with Dialer Watch on a router running OSPF? I know that some Cisco document says that Dialer Watch is only supported in EIGRP and IGRP. But others say any Dynamic routing protocols. Also, has any one used the IP OSPF Demand Circuit? This option is suppose to control the types of LSAs that are sent across the dial line. It reduces the amount of Access-list that is needed to monitor the traffic. Basically, I am using 4 BRIs in a Dialer Interface with ip unnumbered Loopback0. Then, I will be using Dialer Watch to trigger the ISDN calls and run OSPF Demand Circuit to control packed over the dial link. Defaulting back to the serial link will be done based on OSPF cost statement once the link comes back. Does this sound like it's feasible or is it too much to handle?

RE: 7505 Reboots randomly Please HELP
Paul, it is people like you that make this list what it is. I'm sure your post was extremely helpful to many people (even those not involved in this thread). Kudos to you for making me think about my own troubleshooting methodologies and how often I skip the obvious steps. -Original Message- From: Paul Werner [mailto:[EMAIL PROTECTED]] Sent: Wednesday, December 27, 2000 3:49 PM To: [EMAIL PROTECTED]; [EMAIL PROTECTED] Subject: Re: 7505 Reboots randomly Please HELP VERBOSITY BIT IS SET. DISREGARD THIS POST IF IT DOES NOT APPLY TO YOU. A couple of thoughts on this issue. First item is that I am coming in late on this post, so some of my points may already have been covered. Here goes. 1. The first thing I would do is break things down to their simplest level. Remove *all* of your line cards, except for your RSP card. You must ensure that the RSP is installed and fully seated on the top slot as you are looking at the business end of the router. Once you have done that, then attempt to boot your router. 2. As far as booting your router is concerned, I was a little perplexed at your statement in your config below. It indicated that "System image file is "slot0:image.new" What exactly is "image.new"? You need to find the original IOS that you downloaded or bought with this router and attempt to boot from that image. Leave the image name intact, i.e. don't change the image name. For all I know (or can tell), the "image.new" could be for a Cisco 7000 RSP or RP, which will not work for your box. 3. Once it boots, execute the following commands: sh environment all - It should read that "All Environmental Measurements are within specifications". If it does not, your box has a problem with cooling or power. If it is cooling out of tolerance, see if the blowers are running. All six fans must be operational in the fan tray assembly. The router will monitor for a bad fan (or one that is going bad). If it is bad or ready to fail, you will see this at the console: %ENVM-2- FAN: Fan array has failed, shutdown in 2 minutes. Guess what happens next :-) If electrical is out of whack, you may need a new power supply. sh boot - The only thing that should be present here is your config register settings. All other fields should be blank. If not, then what are they set to, and are the settings appropriate? sh diagbus - Since you already removed your cards (except for the one I mentioned, you should only have one slot reported. What you are looking for is that the RSP is seen, the serial number and part number are properly reported, and that the microcode values match those found on "show microcode". Most importantly, it should indicate in the flags field that the item is a 7500 board. If it is a 7000 board, you have the wrong RP. sh flash - Do you have a valid flash image for this router and is it corrupted? See my previous comment on image names. sh proc cpu - Look at the very first line of the output. Does it read like my 7000 router: CPU utilization for five seconds: 2%/2%; one minute: 4%; five minutes: 4% If you have very high values here, something is tasking your CPU. You need to find out what that might be. Are you sure that you have sufficient RAM for your box? The minimum for an RSP is 32MB. 64MB is better and 128MB will have it running fine. If you have only 16MB, it's a wonder it will boot. sh proc mem - look for the first line of output. How much free memory do you have? If this value is in the KB range instead of the MB range, that may be part of your problem, namely you may be starving the router for RAM. sh reload - This output should read exactly as follows: No reload is scheduled. If it reads anything other than what is listed above, find out why. Once (and if) the router runs normally with only the RSP installed, then install your line cards one at a time. Cold reboot the router with each new line card and once it settles down, retype each of these commands and note what changes: sh environment all sh diagbus sh proc mem sh proc cpu You should not see a major change in either of the "show proc cpu" or "sh proc mem" commands. The "show environ all" command should also be within tolerance and "sh diagbus" should pick up each of the new line cards as the box gets rebooted. Additionally, you may also want to check "show ver" to ensure that all newly added line cards/modules are properly reported there as well. When you install your VIP2, install it first without any of the modules installed. If you put the FastE controller on and you notice that the router barfs on it, that may be an indicator that the VIP2 is good, but the FastE controller is bad. One thing I failed to mention early on is that you need to have all of your logging ported over to a syslog server and not your console. In the event that it is ready to do a commanded boot, you will have a log that this occurred. Also, make

Re: So what SHOULD a CCIE know?
Hi, I still seem to strike the odd AppleTalk network, certainly a lot of IPX. I am usually called on when the client IT people are confused. Often the equipment is not Cisco. I guess we each have a different need but it is important that things such as the CCIE have a high level of regard in the IT world. Therefore I would think a CCIE needs to know a lot about a lot. The CCIE needs to be an "expert" on things "internetworking". This to me means if there is something the CCIE does not know he needs to be able to quickly identify what is not known and know who to talk to or where to get the info. As an "expert" the CCIE should then be able to share the acquired knowledge without fear of his or her position.

Does it read like my 7000 router: CPU utilization for five seconds: 2%/2%; one minute: 4%; five minutes: 4% If you have very high values here, something is tasking your CPU. You need to find out what that might be. Are you sure that you have sufficient RAM for your box? The minimum for an RSP is 32MB. 64MB is better and 128MB will have it running fine. If you have only 16MB, it's a wonder it will boot. sh proc mem - look for the first line of output. How much free memory do you have? If this value is in the KB range instead of the MB range, that may be part of your problem, namely you may be starving the router for RAM. sh reload - This output should read exactly as follows: No reload is scheduled. If it reads anything other than what is listed above, find out why. Once (and if) the router runs normally with only the RSP installed, then install your line cards one at a time. Cold reboot the router with each new line card and once it settles down, retype each of these commands and note what changes: sh environment all sh diagbus sh proc mem sh proc cpu You should not see a major change in either of the "show proc cpu" or "sh proc mem" commands. The "show environ all" command should also be within tolerance and "sh diagbus" should pick up each of the new line cards as the box gets rebooted. Additionally, you may also want to check "show ver" to ensure that all newly added line cards/modules are properly reported there as well. When you install your VIP2, install it first without any of the modules installed. If you put the FastE controller on and you notice that the router barfs on it, that may be an indicator that the VIP2 is good, but the FastE controller is bad. One thing I failed to mention early on is that you need to have all of your logging ported over to a syslog server and not your console. In the event that it is ready to do a commanded boot, you will have a log that this occurred. Also, make sure you turn on the following command: service timestamps log datetime localtime Additionally, it *may* be useful to configure the router for sending a core dump. Here are the following commands: exception protocol tftp exception core-file Crash (Crash is the name assigned to the file) exception dump x.x.x.x (x.x.x.x) is the TFTP server IP address exception memory min 100 (will start a core dump when memory is set to drop below 1MB) Keep in mind, a cor

RE: Frame Relay - Lessons Learned...
They might be referring to route-map where you use the route-map to set the next hop on each remote site router to the central site router. So that in order for one remote router to talk to another remote router the route-map tells the router it needs to communicate through the central router... this would be similar to using a frame-relay map ip statment at the remote sites but would be an alternative.

RE: Confused (was Re: is this statement true ??)
Hi, The most common reasons I have found for "late collisions" on a half duplex service lately has been the remote end is configured for full duplex. The full duplex sends well after the half duplex is sending. The most common reason for collisions on a full duplex is the other end is running half duplex. The condition jumps all over the place when running Autonegotiate. Some services run fine on auto other do not. Some will only run successfully on auto. So you must discover which does what by changing the setup on a suspect service, clearing the counters, testing and rechecking the counters. Be aware also that some servers appear to be running full duplex but are not. Others such as Sun boxes can (must) be forced and this must be saved or else the will revert back. There is a lot to this stuff. Teunis Hobart, Tasmania Australia On Wednesday, December 27, 2000 at 01:23:35 AM, Bowen. Shawn wrote: > I might also add I'm a southern fella myself.

Re: So what SHOULD a CCIE know?
Humm... interesting question. >From one point of view... What should be tested (or not tested): In over 10 years of IT work I have only ran across AppleTalk once, so drop AppleTalk (which they are doing). In the same time frame I have only ran across one IPX network that wasn't either in the process of being converted to 100BaseT or was only being used in the DC to connect to a Novell server that was a file server which had it's drives mapped to NT drives. So IPX should take a big back seat to IP. TR, well personally I like it, but again I have only seen one network with TR that wasn't planned to be changed to 100BaseT. Come to think of it, they announced the upgrade a couple of months after I left there. So TR should also be in the back seat. Bridging, humm... well in some respects it is rarely used in the networks I have seen, mostly to get to SNA servers. But then again you had better know your IRB pretty well with all of the L3 switching that companies are being sold these days. L3 switching, better know that pretty well. There are just too many companies being sold L3 that it had better take a bigger role in the lab. The R/S written and lab should take on more of the service provider element. I am not saying that the new SP track should be rolled into the RS track. But with outsourcing and the Internet with VPN, dial and the like taking a bigger and bigger role in most companies, better know your ATM, dial, VPN, BGP, etc, etc. The same can be said for security. Not having taken the lab, I can not really say as to how IPX, TR, or bridging is tested. It could be that it is tested as a primary thing and not as a secondary, e.g. "well looks like we are going to have to deal with that TR segment over rather we want to or not". The same could be said for ATM, maybe it should be a primary and not a secondary.

It is meaningful, but there are lots of jobs that require more and/or more specialized knowledge and experience. CCIE (R&S) indicates a solid understanding of routing and switching, from a deployment and support standpoint, for medium to large enterprises and small ISPs. It does not indicate significant competence in: -- requirements analysis and large network architecture -- product evaluation/selection -- global Internet routing -- protocol architecture, design, and implementation -- formal performance specification, analysis, and tuning; capacity planning -- security requirements and planning (i.e., why you select which IPsec, etc., parameters) -- large-scale network management It appears to be including a good deal of VoIP, but it is not a general telecom certification. The basic CCIE shows substantial competence in workgroup protocols, but not SNA. It considers hosts only in the manner to which they interface to the routing and switching system. _ FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
Re: So what SHOULD a CCIE know?
Well let's start with the obvious. It's well documented that if a CCIE candidate has limited knot-tying hands-on experience to go along with his/her book knowledge, the probability of a "tripping mishap" is increased dramatically. Imagine the embarassment of the candidate, when he/she injurs themselves while entering the Lab examination roomall because of an untied shoelace which could have been easily avoided had the candidate spent more time with "hands-on" exercises.

Re: confused !!! (routing protocol terminology)
One reason the routing protocol terminology is confusing is that different groups of engineers at Cisco implement the protocols, and they use terminology in inconsistent ways. We've had a few questions lately about how to learn Cisco concepts logically. Sometimes you just can't apply logic! &;-) EIGRP doesn't run between autonomous systems since it's an interior routing protocol. I think it's a misnomer that the parameter used to identify an EIGRP group of networks is called an autonomous system number, (although it is sometimes recommended that one use an actual autonomous system number, simply for documentation reasons.) It's also a misnomer to call the parameter a process ID, although I've seen it called that also. It has more significance than simply an identifier for software running on a single router. The number must be the same for all EIGRP routers in an internetwork that share information. OSPF is an exterior routing protocol, so it has a need to identify a group of routers in one domain, under one administrative control. These routers are identified with an autonomous system number. OSPF also has the concept of an area, which is a subset of neighbor routers within a domain. Routers in an area share identical, detailed information about each other's links, but have only summarized information about links outside their area. The OSPF process ID simply identifies the instance of the OSPF software running on a single router. It's like a UNIX process ID. It's just a local housekeeping variable. It has no significance outside the router on which it is configured, unlike the area and autonomous system numbers for OSPF (and EIGRP) which have non-local significance. An interesting feature with Cisco's OSPF implementation is that you can run OSPF multiple times on a single router by using a different process ID for each instance. Hope that makes some sense. Howard has written some good responses about autonomous systems (which he says is not supposed to be abbreviated as ASS, by the way &;-). Check the archives.

You could have router ospf 1 and be part of an OSPF AS on one interface and have router ospf 2 on a different OSPF AS on a different interface. It's ugly and something really uncommonly used (the preferred thing would be to run BGP between the two OSPF AS's but this would be the way to go if you had a single router connecting them, rather than a pair of routers (one at each location)). OSPF has no concept of numbered AS's. If OSPF is being spoken on a particular segment of the network, that's the only instance that's supposed to be running there. I think that you could run two seperate OSPF AS's on the same wire by using different auth keys on the different routers, but some OSPF implementations really scream when they see this. In a nutshell, EIGRP has this mechanism for being able to run seperate EIGRP AS's on the same medium while OSPF doesn't. > _ > FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html > Report misconduct and Nondisclosure violations to [EMAIL PROTECTED] -- --- ** Andrew W.

Re: x.25 connection problem
I am pretty sure you'll have to figure out what should be configured to specify the logical channels coming from the x.25 node. For our network we only specify the "htc" . This can be lic, hic, ltc, htc, loc, hoc. i - incoming t - two-way o - outgoing l - low h - high c - circuit Oh, wait a minute in the book it says for a pvc you use x25 pvc ## instead of like what we use x25 htc ##. I've never done an x.25 pvc before we always do SVC's. (This should match the amount of logical ports configured on the x.25 node. If it doesn't it won't not work most of the time it will most of the time hang the ports on the node if say you configure more channels on the router than are set on the node for your spoke.) The way we normally configure this is with a translate statement, but the way we do it is far from normal. You can try using a translate statement it will probobaly work, but the proper way to configure a PVC is to use the x25 pvc I would just additionally verify the packet size and window size you have configured. >>>Brian >From: "kw.wong(Ah Wang)^_^" <[EMAIL PROTECTED]> >Reply-To: "kw.wong(Ah Wang)^_^" <[EMAIL PROTECTED]> >To: [EMAIL PROTECTED] >CC: voyie wu <[EMAIL PROTECTED]>, terence <[EMAIL PROTECTED]>, >"patrick.lo" <[EMAIL PROTECTED]>, rayyau <[EMAIL PROTECTED]>, >"raymond.yeung" <[EMAIL PROTECTED]>,"danny.leong" ><[EMAIL PROTECTED]>,charlesw <[EMAIL PROTECTED]>, >Cheng Man wai <[EMAIL PROTECTED]>,vincent ><[EMAIL PROTECTED]> >Subject: x.25 connection problem >Date: Thu, 28 Dec 2000 00:30:41 +0800 > >Dear All : > >I went connect to our company cisco 2610 through the lease line to x.25 >system in B company.

Re: So what SHOULD a CCIE know?
I feel that a CCIE should know everything in his technology specialty (i.e. routed global networks with enterprise switching) like he ate it for breakfast. For everything else a CCIE should have a general knowledge and know exactly how and where to find more information on the subject. About the tests: I think they are good, though they could be a bit more in depth (maybe more questions on certain topics). When I took the written the first time I came out of it with a headache and a clear path of what I needed to work on. I'm glad to see that they are retiring some of the older protocols, but for those that work strictly in the IP area it can be a burden to learn things we have never touched and don't work with. -j Chuck Larrieu wrote: > We've all seen a number of comments about the CCIE written and the CCIE Lab, > regarding content.

RE: CID test vs. CCIE written
It is similar in length, but it encompasses different items. The "feel" is similar, though you can go back through your answers on the written as many times as you want. I don't care what Cisco's www site says, it still has TON's of Token Ring questions, you better know RIF's really well. There is ATM and LANE on it as well. Also some very detailed circuit questions. IPX framing questions, basic DLSW, and STUN were on it as well. I took both of these last week, CID on Monday and CCIE on Tuesday, I was still amazed at some of the abstract crap they through at me.

It depends on how you configure it. If you use Legacy DDR it will be locked into use as a backup only. If you configure with a DIALER interface, then it is used on a first-come, first-served basis.

RE: Interface backup
Yes . The better way to do it is to create virtual dialer interfaces. ie dialer 0, dialer 1 etc You can make dialer 0 the backup to the serial line, while dialer 1 can be used for other purposes. The obvious risk with this is that the BRI may be in use when you need it for backup purposes. You may want to 'reserve' 1 channel of the BRI just for backup use (which can be done using dialer interfaces I think) > -Original Message- > From: Groupstudy [SMTP:[EMAIL PROTECTED]] > Sent: Wednesday 27 December 2000 18:21 > To: [EMAIL PROTECTED] > Subject: Interface backup > > Once you make a BRI interface a backup to say a serial interface, does = > it lock it down so that it is not useable for any other purposes? > > eg: > interface serial 0 > backup load 60 5 > backup interface bri 0 > > Cheers. > > _ > FAQ, list archives, and subscription info: > http://www.groupstudy.com/list/cisco.html > Report misconduct and Nondisclosure violations to [EMAIL PROTECTED] * DISCLAIMER: The information contained in this e-mail may be confidential and is intended solely for the use of the named addressee.

RE: Interface backup
If you specify a physical interface such as bri 0, then the physical interface is placed into standby and is unusable for any other purpose. The way you get around this problem is to use dialer profiles so that the logical dialer interface is placed into standby instead, leaving the actual physical interface free to use for another purpose.
