Re: ip ospf dead-interval [7:64311]
shoulds like you're trying to answer a trick question on a test? I suppose "The Long and Winding Road" wanted you to work for your answer, but I'll come out and tell you. ospf defaults the dead-interval/hold-time as a multiple of the hello time, so if you change the hello time the dead interval changes automatically also. scott ""nilesh bothra"" wrote in message news:[EMAIL PROTECTED] > Q.

Wouldn't the poster learn more from working it out? I liked "The L&W Road's" answer much better. :-) Wouldn't the poster be a better representative of the relevant certification having worked it out? For example, if the poster is going for CCNP and manages to pass because people provided answers instead of methods for figuring out the answer, is that a good thing for the rest of us who wish CCNP to be a respected certification? The poster asked for suggestions, not answers, and that's what we should have provided. Hopefully the poster will try this in a lab. There is at least one minor gotcha that I can think of. Hey, you had to expect to get slammed for this! ;-) I'm doing this with all due respect and a recognition of how fun it is to give an answer. I think a lot of us participate on the list partly to give answers because it's fun and a nice ego stroke, myself included. But the real goal of Group Study is to help people learn.

Re: ip ospf dead-interval [7:64311]
good point, I'm new to the forum and wasn't quite sure of what approaches to answers people expected. I do like his approach to answering it, because if you look at the link, the answer is in there (with the use of some deductive logic). the only thing that worries me though, is that if people never get a straight answer, will they then stop asking questions? its nice to see an open forum about cisco networking thats actually well populated, I'd like to support it as much as I can. scott ""Priscilla Oppenheimer"" wrote in message news:[EMAIL PROTECTED] > Scott Roberts wrote: > > > > shoulds like you're trying to answer a trick question on a > > test?

There are a couple of ways to look at this. give someone a fish, or teach them how to fish? what level of expertise is the person asking the question? The question itself - how to change one ospf timer without using the timer-specific command - is a standard trick question for a lot of CCIE practice labs. It's not generally the kind of thing that comes up in the CCNA qualification exam. Making the assumption that someone is prepping for the CCIE Lab, should they be expecting specific answers to specific questions? Or should they be spending a bit more time acquiring the expertise that is going to be tested in the Lab? Maybe there are CCNP practice labs out there that ask these kinds of questions as well? Maybe the guy asking the question is a newly minted CCNA and is starting his road to CCNP? Sure, ask the question. My own opinion, and my own advice to anyone who dreams of attaining the CCIE, is to start early and often - get into the habit of looking things up in the documentation first. Knowing your way around the doc CD or the Cisco CCO doc pages is a skill that will serve you well in a lot of different places, including the CCIE Lab itself. > > scott > > ""Priscilla Oppenheimer"" wrote in message > news:[EMAIL PROTECTED] > > Scott Roberts wrote: > > > > > > shoulds like you're trying to answer a trick question on a > > > test?

Welcome to Group Study. Nobody ever gets a straight answer here! ;-) And usually they shouldn't. With the exception of the ones and zeros that go across the wire (or air), most other things in this industry are simply not black-and-white.

So, what layer does ARP run at?

RE: ip ospf dead-interval [7:64311]
CiscoPress book for CCNP routing is very specific on changing hello setting and having dead/interval setting changing automatically. I would have given the answer and said where I found it. What some people are suggesting is that when anybody posts a question the answer should be, "buy my book". If people do not to want help other people out, or at least point them in the right direction, then what is the point of groupstudy? Just like any other sire, this one is also not perfect. I guess I just have to learn whose threads to bypass and not read at all.

I re-read the materials but I'm missing it. Where can I find the answer?" that's why I posted the link to the page on CCO where the appropriate comands are found. it is also why I suggested that a good habit to get into is to use the doc page first. >Just like any other > sire, this one is also not perfect.

Re: ip ospf dead-interval [7:64311]
in real life its hard for me to keep my mouth shut, so even if I intend to be elusive in answers from now on, I'll probably just shoot my mouth off here too and just give the answer.

Because I do can use the command 'ip > ospf dead-interval' The original question was how to change the dead interval without using the dead-interval command.

That's new. Older versions of IOS used to change the hello if you changed the dead. Newer ones don't, although they do change the dead if you change the hello. By the way, in the real world, you would want to change the neighbors too. They will fail to become adjacent if they don't agree on these timers, if I'm not mistaken. This thread has exceeded its dead interval, I think! ;-) Priscilla > > > > sh version > > R1#sh ver > Cisco Internetwork Operating System Software > IOS (tm) 2500 Software (C2500-JS56I-L), Version 12.1(17), > RELEASE SOFTWARE (fc > 1) Message Posted at: http://www.groupstudy.com/form/read.php?f=7&i=64753&t=64311 -- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
