    Well IGRP isn't very hard for me so I think I can get by without it. Pretty easy to configure.

    I just dont understand why my IOS would have RIP, EIGRP, OSPF, etc...but not IGRP.

    I don't think that's the case even if true. Even if it was discontinued I don't think my IOS images are so new that they wouldnt have it on them.

    here is a link to a snap shot of the CCIE ROUTING TCP/IP book. If hyou look on the second paragraph it tells you that IGRP has been discontinued as of IOS release 12.2(13)T.

    Amazing how much more you learn with hands on lab work. There were a few things I wasn't sure about prior to re-reading my EIGRP section and actually configuring an EIGRP network on my router. I can't stress enough the importance of hands on. Over the past few days I was kind of down because for some reason I was worried that the information wasn't clicking all together like it did for me 6 years ago when I was rocking cisco certs left and right.

    Some of you may know what I mean. It's like you've just read through all the material, even a few times, and you see it all layed out in your head...but it just wont come together into one big picture that all makes sense, together. Well after starting on my labs yesterday I started to notice it all slowly coming together. You know, that little field of images in your head that all of a sudden connects and you're like..."oh, I get it".

    It might sound stupid but we're all tech geeks here so you'd be able to get this more than anyone else I could ever tell. It's almost like I'm starting to recognise what's on that screen...



    You get my point.

    Like, tonights clicks had to deal with summarization and discontiguous networks. To be honest I never really understood what discontiguous networks were but I guess in my own words they are simply 2 networks with different classful boundaries (class b and class c for example) being brought together into one network by the use of EIGRP (which supports discontigous networks) by the use of the no auto-summary command. And then that opened up the next door in regards to summarization because without the no auto summary command EIGRP wouldnt be able to support VLSM, since it would automatically bring the mask boundary back to its default classful mark.

    Ok, did that make sense to anyone else except for me?

    Wife's sister came down this past weekend with her boyfriend and got engaged while they were here. They were sleeping in my 2nd bedroom (i.e. lab). Had no access for the 3-4 days leading up to the test so had to cancel it.

    Sigh.

    Glad to hear things are coming together for ya! Some things click at different times for different people. But doesn't it feel good to know that you are starting to see things in a larger perspective and starting to see how everything works as a system and how parts of the system are influenced by things you never thought about before? OKay that was a really bad run-on sentence.

    Just did a cancel. Gonna reschedule it for maybe a few weeks from now. I noticed during the 2 week stretch that I might not have given myself enough time. Seems labs take a bit longer than I thought and I just just gotten up through all my routing protocols before the family came down. Doubt 3-4 days would have been enough to properly cram in switching along with WAN protocols. Their easily some of the most intricate things to run through in the lab.

    May have been a blessing in disguise that they came down because I probably would have just given myself those 3 days to get it all in and even if I wasn't prepared would have taken the test. I'm rolling again though and shouldn't be long.

    Yeah, I had it all in the past when I was popping these certs like tic-tacs. Was wondering why it felt empty this time around. I'm pretty sure once I get through all the labs from routing, to switching, to WAN, it'll all come together as a whole...........

    ..........And then I'll be able to fly again.

    Code:
    Router(config)#router eigrp 1
    Router(config-router)#metric maximum-hops ?
      <1-255>  Hop count
    this is from my 2610
    I was scratchin my head over this one for sure. I don;t know where 224 came up but the confusion it caused is all over the certification community. I googled it several times.
    I've just copied this from Wikipedia...
    '224 for EIGRP and 255 for IGRP'.

    Good to know that it is 255. that is a more familiar sounding number anyway right?
    But more importantly, I will surely swear a blue streak if I miss getting 85% because Cisco has it wrong!
    I did post this earlier but it's dissapeared! I took a look at Wikipedia and it said that IGRP was 255 and EIGRP was 244.

    never believe anything you see on wikipedia. That can be edited and modified by anyone. In fact, last year there was a big deal on the news about an article on wikipedia that gave some kind of false information about a senator and the media went crazy on it.

    Secondly, there are various resources that will say EIGRP has a max hop count of 224 but I don't believe it. I don;t know which book it got misprinted in or if maybe that was an old parameter that got changed. Not sure, but I know what I see on a real router with 12.1 IOS. Which isn;t the most current version but close enough. Plus todd lammle states that it is 255 in the Sybex book. And I believe that book was published in 2004 so.......If the it comes up on the test i'm saying 255.

    I agree...
    Cisco routers say it, so does Todd's book...you can't go wrong there!!
