    Can someone please tell me what is the correct way to add the 'delay ' factor into route resdistribution. eg. If the delay is 100 or 5 or 8 ms ?

    e.g.
    Bandwidth = 64kbps
    Delay = 100 / 5 / 8MS (any of these)
    Reliability = 255
    Load = 1
    MTU = 1500

    Now say I'm redistributing below level 1 routes what will my delay be ?

    #redistribute isis level-1 metric 64 100 255 1 1500

    Is it just put in as above ie 100 and if I was using 5 it would be as below etc.

    #redistribute isis level-1 metric 64 5 255 1 1500

    Please clarify ?

    Thanks for your help

    Personally, I have no idea.

    Just a *bump* to see if anyone else can help.

    Tks ... Surely someone has a clue ??
    I think it is divided by 10. e.g. if it is 100 then 10 would be the answer. The reason I ask is because I saw some practice q's which had the delay as 2 and 5 so this is what confused me as I dont think they would be in decimal format.

    Still Stumped by this one!

    I can find references to the sytax that you are trying to implement, but can't find any reference as to how you work the values out. :blink

    If you manage to get an answer to this one from else where please let us know.

    Hi

    DELAY
    ms = miliseconds
    us = microseconds = 1/1000 miliseconds

    Delay is set in 10 microsecond units
    Thus a delay of 3ms would be defined as 300

    so assuming 64KB (512Kb) and 3ms the default metric statement would look something like this:

    default-metric 512 300 255 1 1500

    EIGRP will use the formula to create an overall metric for those routes that were injected into the process.

    There is a good cisco paper on this in detail located at: http://www.cisco.com/en/US/customer/tech/tk365/technologies_tech_note09186a00800c2d96.shtml

    Did the BSCI exam today and passed with 879. It was 776 to pass so maybe scores have been lowered. Dont know how the score them but I definitely got a few wrong and guessed about 3.
    One of the simulation questions was on exactly the above to configure the metrics for these protocols so thanks again Jonahtan for your answer. I just checked it last night to see if anyone had replied.
