RE: MCSE or CCNA or both [1:763]
I'm not so sure, myself within 48 hours of updating my resume online to reflect my CCNA I received a job offer. Without having both certifications no one would talk to me about employment (this with 3 years experienceas a network admin/help desk)Of course when going for entry level positions it certainly helps if you are or can be mobile (i.e. have the ability to relocate). I moved to Kansas City to take a position working for Sprint on their ION platform as a Network Operations Specialist. I get to learn ATM, troubleshoot Nortel PVG's, Lucent Stinger DSLAMs, Cisco 12012GSR routers...etc... None of this would have been possible without my ability to move and my CCNA (having an MCP was an added bonus). Good Luck all looking for work (keep an eye on Sprint for openings BTW)and once again thanks to all on this who spend their own time to tutor those of who are climbing the ranks. Gragg Vaill MCP CCNA -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]] Sent: Thursday, November 09, 2000 7:23 AM To: [EMAIL PROTECTED] Subject: RE: MCSE or CCNA or both [1:763] There is another forum here :Jobs@groupstudy. In the past days I remember seeing several postings of new CCNA holders who were not getting any job offers with their new certification. BUT who knows what THEIR experience overall was like?? I believe that from what I have seen a CCNA will NOT guarantee you a job (neither will an MCSE)and that in the end your all around knowledge/experience is what will count. Hiring managers are generally smart enough to know that just because someone has an MCSE or CCNA does not necessarily mean they can really do the job. Many conduct interviews with numerous technical questions to test your level of expertise. The best you can hope for is that the CCNA/MCSE will win you an interview. We all hope that a company will hire us and give us the opportunity to get the experience to warrant that high paycheck. If you find such a company please let me know as I will go work for them also. Of course if you have the experience to do MCSE and/or CCNA level work you can probably get along without either certification. T.

Re: Which one is correct?
I am assuming you have two PVCs at each branch office for either a doubly-large CIR, or because you have two physical interfaces. either way, unless some weird frame-switching is being done, and im not sure if this is possible ( though it prolly is ) each branch office pvc is going to require a corresponding pvc at the CO. you will need to use six frame-relay map commands on the point-to-multipoint at the CO.

Re: OSPF Totally Stubby Areas and area default-cost
Totally stubby is a cisco nob that takes the concept of a stub area a step further. In a stub area, only LSA types 1 (router) 2 (network) and 3 ( summary) flow within the area. Hence, no routing information concerning prefixes outside of the OSPF domain is injected into the area. In a totally stubby area, the flow of normal type 3 LSA's is halted as well. This leaves the area with no information about any prefixes outside of the area. In order to allow traffic to exit the area, a single type 3 LSA is propagated by each ABR which advertises a default route. The default cost nob simply allows you to set a cost for the route instead of using the standard OSPF metric to the ABR itself. Hope this helps some Pete *** REPLY SEPARATOR *** On 11/08/2000 at 4:29 PM Bob Hunter wrote: >Hi, > I'm confused on the subject of totally stubby areas, and the command "area >default-cost".

Re: Which one is correct?
You're talking about 2 PVC's going to the same site from one site? Like Site A's connection to Site B's connection has 2 PVCs? I believe if that's the case, you'll need 2 DLCIs since you need 1 DLCI per PVC. For 3 subinterfaces, you'll have a total of 6 if I understood your question right.

Re: Which one is correct?
Sorry for the unclear question. What I was trying to ask was the FR configured with Multipoint. When multiple PVCs are configured in a subinterface of the central site router, I was wondering how many local DLCI numbers are needed. There are three branch offices, and each branch office has two PVCs going to central site router. Then there will be totally 6 PVCs in this whole structure. From the view of central site, its router has three subinterfaces, and each subinterface has two PVCs. Now, how many DLCI numbers do I need totally at central site router? Would it be 6 because there are six PVCs? or Would it be 3 because there are three subinterfaces? I hope this question is clearer. --- "Peter I.

Re: VoIP
Don't take this the wrong way, but I have a couple of questions. Since you're being compensated (paid) by your customer, how do you intend on compensating someone in this group for helping you? If you don't compensate someone for helping you, how do you know that your helper didn't just give you enough rope to go hang yourself in front of that customer? i.e. They gave you enough information to think you know what you're doing but not enough to be successful. And since money is involved, and hence the concept of harm (legal definition). Do you have adaquate liability insurance to protect not only yourself but also the person who helps you? That should just about cover it, thanks. Rodgers Moore ""Alex Madjeski"" <[EMAIL PROTECTED]> wrote in message 002301c04c37$648f5080$[EMAIL PROTECTED]">news:002301c04c37$648f5080$[EMAIL PROTECTED]...

Re: OSPF Totally Stubby Areas and area default-cost
Bob, A stub area may have more than one ABR. Stub areas are areas into which information on external routes is not sent. Instead, there is a default external route generated by the area border router, into the stub area for destinations outside the autonomous system. To take advantage of the OSPF stub area support, default routing must be used in the stub area.An area could be qualified a stub when there is a single exit point from that area or if routing to outside of the area does not have to take an optimal path. The latter description is just an indication that a stub area that has multiple exit points, will have one or more area border routers injecting a default into that area. Routing to the outside world could take a sub-optimal path in reaching the destination by going out of the area via an exit point which is farther to the destination than other exit points Hope this helps. I derived this information partly from Doyle's book on TCP/IP Routing and the CCO.

Need help setting up Teltone Isdn Demonstrator
This is my setup: 2504(int bri0)-Demonstrator-2503(int bri0) The Demonstrator came with a program that allows you to change the configuration of the Demonstrator. Some of the parameters you could change include: D Channel X.25: None Permanent (PVC) Dial-Up (SVC) B Channel: None Permanent B1 Permanent B2 Permanent Both Loopback Caller Identification: On Off Electronic Key Telephone Service: On Off Can anyone tell me what configuration I should give the Demonstrator so that I could get connectivity between the 2 routers? Also, I'm extremely new to Isdn so can anyone tell me if the cables I use to connect the 2 routers to the Demonstrator are just regular straight-through Rj-45 cables, or do they have to be cross-over cables.

Question about eigrp
I have been working with a system which has under its eigrp process this command "eigrp stub connected". From what I gather this perticular router acts as a stub and receives no eigrp updates to its routing table but does receive and send out hellos because it has established a neighbor relationship to the hub router. There is a default gateway which seem to route all packages out of the router and into the hub router. Anyone have any links or info on this. IOS version is 12.0(7)T and I have looked in the CCO but I see nothing so far. Anything on this for reading purposes would be much appreciated. Sincerely, Raul F. Fernandez
OSPF Totally Stubby Areas and area default-cost
Hi, I'm confused on the subject of totally stubby areas, and the command "area default-cost". From what I'm reading, one of the qualifications of a totally stubby area is that if multiple exits (ABRs) exist, routing to outside the area does not have to take an optimal path. Does this mean that each router within the area picks the closest ABR as the gateway to everything outside the area, and that there is no way to control the default route? If so, does that imply that the area default-cost is used for incoming routes? Would incoming routes even exits if the area was a totally stubby area? I would very much appreciate it if someone would please set me straight. Thank you.

CCIE Written Passed!
The second time around was a cinch! (I failed it the first time with a 66%. ) I studied for a couple more weeks and took it again this morning and passed with an 84%. Both times I only had about 5 minutes left on the clock when I was finished. The first time, I had done really well in only 3 areas where I'd spent the majority of my time studying. This time around, I studied only in the areas I had done poorly in before. It really showed. I scored 100% in three areas and over 90% in three others. (And, the areas that I skipped reviewing this time around did not suffer much from lack of review, either.) I just needed a little more time for all the pieces to settle into place. Now, it's off to the Lab!!!

RE: Some OSPF Questions
Chuck, Thanks for testing. Now my curiosity is at an all time high. Is it possible for you to do the test with 4 routers ? My theory is that 2 or maybe even 3 routers are not enough. Here is why: 2 routers on a broadcast net will always have a DR and BDR. If the DR goes away, the DR will know it is alone on a broadcast net. It will become a DR in its own right. It will not be taking over any duties of the former DR. The time to realize that it is alone will be 40 secs(default). A 3 router net might have the same issue. The absence of the DR will trigger a promotion of the BDR. The remaining router will become the BDR. This seems to be consistent with the broadcast net rules. Although the code obviously selects BDRs and DRs very early, maybe the duties of DR flooding do not start until there is at least one other DRother on the net. I only have two routers available and my test produced essentially the same results as yours. Something I did notice is that the Network type 2 LSAs never aged. If a 4 router test produces the same results then it will be difficult to say whether LSAs or hello packets determine when the BDR takes over for the dead DR. I hope they never ask this question on any test.

Worth office connected to an office in Houston (via FR), and office in Kansas City (via FR), an office in the DFW area (via ISDN) and the owner's home (via ISDN).

Re: routing protocols vs Tcp/ip model
Routing protocols have network-layer functionality, regardless of whether they use an IP header, IP/UDP header, IP/BGP header, or no header at all above the MAC header (IS-IS) to transfer their information. If we can't agree that routing protocols have network-layer functionality, we should just throw in the towel and agree that pigs have wings.

RE: Redistributing routes
Achieving symmetric traffic flow in this situation will be challenging (using BGP). Without seeing your configs and getting a better feel for the network I could suggest you move toward an asymmetric scenario. Simply run HSRP into your own LAN and allow all outbound to flow out one line, and set a MED value to direct inbound traffic to the other. If you have similar inbound and outbound flows, this will work alright. It will provide you with redundancy at a cost of maximizing your bandwidth use. Alternatively, you could sacrifice a little redundancy and aggregate the two T'1s with MLPPP. I would opt for the first scenario myself.However, your network could be more complex than this and other options may likely be viable.

All the literature we could find simply said that the BDR waits for the specified time period but never said what that period is. 2) In a Point-to-Point network in which the router in Area 0 is connected to FR, ISDN, X.25 or ATM branch offices (networks), how does convergence and updates take place? From what we've found a DR and BDR is not elected in a strictly Point-to-Point network. I think an example would explain this question better: We have one 3620 router in our Ft. Worth office connected to an office in Houston (via FR), and office in Kansas City (via FR), an office in the DFW area (via ISDN) and the owner's home (via ISDN). The 3620 is behind a firewall (Pix 520) and the firewall is connected to a 1720 going to the Internet. I'd like to implement OSPF on our network simply for the experience. However, I don't have 2 routers internally on our Ethernet LAN that can be configured for Area 0 and elected to DR and BDR. All other routers connected to that router are via NBMA Point-to-Point connections. Since I only have one router on the Broadcast Multiaccess network (the 3620) and routers connected via PtoP don't participate in DR and BDR elections, how would updates occur? Can their only be one DR (in this case the 3620)? 3) The books and tutorials all state that "router ospf 6" defines ospf on the router with a process ID of 6. They then all say that you shouldn't define more than one process. Does that mean that you can have a router with the following: router ospf 6 network 10.100.0.0 0.0.255.255 router ospf 7 network 10.200.0.0 0.0.255.255 If this is an allowed configuration, what kind of instances would it be used for? Also, exactly what is the process ID used for? _ FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED] _ FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED] _ FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]

RE: multiport nics or nic teaming
I can suggest SUN Systems' "Cluster" services. If the data and connectivity is important enough to have HSRP and redundant switches, I would check out a cluster of 2 or more Sun servers. This software suite will allow each machine to keep an eye on each other and if one goes down, the other will take over. It is not trivial to do but it is much easier than trying to force the same IP on two different ports in the same machine with automatic redundancy. TCP/IP does not like two identical IP addresses on the Internet or on the same subnet much less on the same server. Since I am surrounded by SUN servers and Cisco routers, I will suggest that if you have "machismo" you can try configuring one port with the ifconfig command and then use the "unplumb" switch to deactivate it. Configure the next port with the same IP and then activate it with the "plumb" switch. If this works and it is a big IF, (I expect the TCP/IP stack to complain) you would still have the problem of making it fail over automatically. In addition, SUN has the ability to place network interfaces into "Interface Groups" but these basically have different IP addresses acting as a group. Much like a virtual address. That is also worth a try. Lastly, multi NICs are basically for placing a device on two or more subnets. If the hardware manufacturer says his NIC ports can all have the same address please let me know. I would be very interested in obtaining a few of them myself.

RE: Some OSPF Questions
It appears that there might be some small misunderstanding about DR and BDR relationships. On a Multi-access net the DR is the "pseudonode" which represents the net. It is similar to NLSP in this regard. All OSPF routers refresh their LSAs occasionally. The DR sends LSA type 2 to all OSPF routers on the net. This way all routers get a refresh of who is who etc. Hellos are only used to establish and maintain adjacencies. Prior to 11.3 LSA's were sent every 30 minutes and all routers refreshed their databases. Now the default for all LSAs is 4 minutes(240 sec). This is configurable by using the command "timers lsa-group-pacing". A BDR, being an OSPF router would miss any other OSPF router after 10 times 4 = 40 secs using the default. This will cause it to change its routing behaviour, however the BDR to DR functionality would not take effect until it did not see the LSA type 2 packets from the DR after the set time(4 min default). I am not sure if that has been changed in 12.x the DR is the only router who originates LSA type 2 packets. Winston -Original Message- From: Frank B.

What are you refering to? If you want to assign the same IP address to multiple interfaces on the same router, then you must disable routing and configure bridging.

Another problem is that the OSI application layer definition in OSI has evolved into a much more object-oriented design. The most recent thinking split layer 7 into certain common services, such as the Application Context Service Element and Remote Operation Service Element, with the "applications" such as FTAM and MHS running above them as a set of objects (e.g., MHS MTA's, UA's, message stores, etc.). ROSE is the equivalent of RPC.

When I had this problem assigned in a chemistry class, we measured the head of a pin, then assumed the extreme case of an osmium pin (highest density element). Assuming that angels dance on the surface of the pin only, and that angels primarily exist in a particulate form, compute the surface electron density at the surface of the pin. Only surface electrons are available as dance floors. If you assume all angels can instantaneously exchange position during their dance, the number of angels equals the number of surface electrons. If the angels must dance to an angel-less electron, ignoring distance, the number of angels is more like surface density/2.

Re: Port Assignment with Static IP
Hi Normally you would see a /30 (255.255.255.252) mask on a outside interface. Instead use something that has a few more host IPs available on the interface, i.e. /28 (255.255.255.240) which will give you 14 host IPs with 12 available after the interfaces are addressed.

Here is short example: Int S0 ip add 12.168.10.1 255.255.255.240 (far side would be 12.168.10.2 255.255.255.240 leaving 3-14 available) ip nat outside int E0 ip add 192.168.10.1 255.255.255.0 ip nat inside ip nat inside source list 19 interface S0 overload (this will overload the 12.168.10.1 address and allow internal users access via 1 IP) ip nat inside source static tcp 192.168.10.6 80 12.168.10.3 80 extendable ip nat inside source static tcp 192.168.10.7 80 12.168.10.4 80 extendable (and so on) ip nat inside source static tcp 192.168.10.17 80 12.168.10.14 80 extendable ip access-list 19 permit 192.168.10.0 0.0.0.255 HTH -- John Hardman, CCNP MCSE+I ""Brian Lodwick"" <[EMAIL PROTECTED]> wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]... > Adele, > If you were talking about NAT how would the data ever get to the correct > destination in translation if you were able to overload the port with > multiple IP's and able to overload the IP with multiple ports? > > John, > How would you be configuring what you are talking about? > > >>>Brian > > > >From: "John Hardman" <[EMAIL PROTECTED]> > >Reply-To: "John Hardman" <[EMAIL PROTECTED]> > >To: [EMAIL PROTECTED] > >Subject: Re: Port Assignment with Static IP > >Date: Sat, 11 Nov 2000 10:02:41 -0700 > > > >Hi > > > >I assume you are talking about NAT/PAT, as your post is a little short on > >info. > > > >Anyway, think about it for a minute, how would it possible for one IP to > >have two of the same port?

It does not go into the depth that Doyle does. Yes there are some things that are explained a bit differently, and perhaps a bit more clearly. There are a lot of things that will make no sense if you don't already have some understanding of routing and particularly Cisco routing 2) there are LOTS of lab / study exercises. What makes this book particularly useful is that there are lots of configuration examples, numbered line by line, with the text referring to particular lines to emphasize or clarify points. 3) Many of the exercises can be done with only three routers 4) The chapter on redistribution is particularly useful in terms of configurations and show command outputs. All of the examples are based on a three router pod ( except for the last two- eigrp-ospf and complex, which is rip2, eigrp, and ospf. Both these are 6 router pods ) I have not finished the book yet. What remains for me to read are chapters on NAT, static connectivity to the internet, BGP, and troubleshooting. But from what I have read so far, I am looking forward to some good and useful material in an easy to read format with lots of examples from show and debug outputs. I think that this book is well worth adding to one's study materials, particularly for Lab preparation. Also, I remind everyone, pick up a copy of my assembled tips for Lab preparation as provided by three different CCIE's who have been regular participants here at groupstudy, and who passed the Lab on their first try. www.chuck.to/CCIEAdvice.txt file name is case sensitive. Web site is still feeble but getting there.

RE: routing protocols vs Tcp/ip model
Howard, I know we've had this discussion before here on groupstudy. I also accept that there remains a lot of confusion of OSI terminology with PC terminology. I.e. application on a PC versus OSI application. That said, I am looking at the Certification Zone OSI paper. In it is the statement that the application layer provides common services to specific application programs, including file transfer, messaging ( not in the sense of e-mail messages ), directory lookups, etc. ( I have paraphrased this a bit, but I believe this is true to the original sentences ) If I have a Linux box, and on that Linux box I am running RIP and OSPF, am I not running user applications? Is the operation of those applications using services at the OSI application layer? I.e. receiving messages, sending messages, doing what might be arguably called "file transfers" etc. ? The purpose of the user applications ( as opposed to the OSI application layer ) is to provide particular functions and distribute particular information, is it not? A router is a computer, after all. It's architecture is based on the Von Neuman model. It has a CPU and memory and software that performs various operations and functions. The is an operating system that handles the i/o and integrated into that operating system are the various - dare I say it? - functions or "applications"? ( as an aside, isn't this what Microsoft is getting bonged for doing? :-> ) I agree that it is not the best use of time to spend countless hours messages arguing how many angels can dance on the head of a pin. But I do wonder if the code that results in a BGP table, or an OSPF database might by some standards be considered "user applications" which in turn use functions that are defined within the OSI application layer ( e.g. file transfer - routing updates? - notification messages - hello packets? LSA's? ) Yes, routing is a layer three function, but is it incorrect to say that there are things going on at other layers that make the layer 3 functions possible?

Re: Port Assignment with Static IP
Hi I assume you are talking about NAT/PAT, as your post is a little short on info. Anyway, think about it for a minute, how would it possible for one IP to have two of the same port?

It's really not the fault of OSI, because there are documents that supplement the original model, such as the Rout(e)ing Framework, Internal Organization of the Network Layer, Management Annex, etc. The OSI stack principally was drawn to show how standard communications service user applications, which run on top of the service interface to the application layer. Management was something of an afterthought, and what is called system management -- think SNMP, or the OSI rough equivalent, CMIP -- does indeed involve an application layer protocol and a management application above it. Routing, error notification, etc., are considered layer management. There is nothing "above" them; they are part of the infrastructure for a given layer. So,all of them are logically layer 3. The issue of the mechanism they use to transfer information between them is independent of the layer they manage. In Chuck's table below, EIGRP and OSPF do have transport functions that are part of their own design--which have a TCP-like flavor. For that matter, ISIS runs directly over data link. >Recently an instructor in a class I was taking said something I found >interesting.

I think it might have been only the books they had a surplus of that got sent across. If anyone from cisco is reading this you have *no* idea how annoying it is to spend 20 minutes reading the marketing stuff that goes with the books (because some of us actually do read it instead of going straight for the CCO users button), then fill in all the details, click the next button and see "US and Canada only". It actually doesnt do you much good either as you generally feel cheated out of those 20 minutes and let down after getting all excited. Besides if anyone did that over here theyd be in court quick as a flash for breaching contract since the eager punter has completed their end of the bargain and given you the marketing info before its mentioned.

Best Lab prep books?
Group, I know this question has been asked quite a few times but I couldn't find any particularly on the lab study guides from the archives lately, only the ones on great study material in general for the CCIE like Halabi's BGP book and Radia Perlmans Interconnections. I am looking for input on which ones people prefer for the lab preparation like the Giles lab study guide or Caslows or if there is another one better. I know I remember a while ago reading other listings and I think they were saying Caslows book was good, but at the time I wasn't even thinking about the CCIE at all and didn't pay enough attention. Thanks in advance guys! >>>Brian _ Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com.

Hiya - from the sounds of things you have got quite a job there :) You might want to look at linking up with these guys - http://www.freenet6.net/ theyve been doing similar things for a while although I think its more aimed at application developers and netkids who want to try it. http://www.ipv6.org/impl/routers.html has links to where to get the ipv6 beta software for lots of different routers. http://www.cisco.com/warp/public/732/ipv6/index.html has links for betas of ios 12.2 with ipv6 and a whole bunch of white papers etc. on ipv6. > > If you're the type that likes book learning before you actually > put your hands on something I can recommend IPv6 second edition by > Christian Huitema ISBN 0-13-850505-5.

freebies
i would like to make a comment regarding the thread on cisco free stuff. i am based in the UK. a few months back i completed the questionaire to get my free copy of 'IP Telephony' by Mcgraw Hill . when i got to the end, i noticed to my annoyance 'only valid in US and Canada' or something. Anyway, i had gone so far that I continued. lo and behold, a few weeks later my book arrived. moral of the story? apply anyway wherever you are. you never know! right i'm off to apply for my free alarm clock thingy. ian P.S. i'm STILL having to wade through gallons of HTML rubbish on this list which i should not have to. i still do not understand how people who do not understand how to turn off HTML or who don't see why they should can honestly expect to pass tricky CISCO exams. _ FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
Re: routing protocols vs Tcp/ip model
According to the Cisco BSCN material, IGRP uses protocol number 9 and exist at layer 4 RIP uses protocol number 520 (UDP) and exist at layer 7 OSPF uses protocol number 89 but does not idicate where it resides EIGRP uses protocol number 88 resides at layer 4 and BGP uses port number 179 and relies on TCP Very confusing . - Original Message - From: "Chuck Larrieu" <[EMAIL PROTECTED]> To: "Zhang Jin" <[EMAIL PROTECTED]>; <[EMAIL PROTECTED]> Sent: Saturday, November 11, 2000 12:18 AM Subject: RE: routing protocols vs Tcp/ip model > Recently an instructor in a class I was taking said something I found > interesting.

6509 Question
Ok, this is a follow up to my e-mail last night, as it would seem, the problem was not with my route configuration, but rather with the MSFC detcing a link failure. So here goes the next round of questions. I have two 6509's configured for redundant connectivity. I am trying to get the MSFC to detect a link failure at Layer2 so that the routing table will be updated and packets can traverse the alternate path. The problem seems to be that when all ports fail in a VLAN that the VLAN is still considered up. Is there any way to get the MSFC to view a port on the catalyst as a single interface and detect a failure on that link? If not, how can I have layer 3 redundancy in the event of a link/module failure?
