  1. Hello Rene,

    this was a really good post! One statement that I personally dont liked:

    “ou don’t want your EIGRP routers calculating 24/7 and sending updates to each other just because the load or reliability of an interface has changed. We want routing protocols to be nice and quiet and only base their routing decisions on static values like bandwidth and delay.”

    I think everyone would love to have a routing protocol that dynamically adapts to the network state but the processing overhead for the routers in your network would be a nightmare.

    Thank you for this post.


  2. EIGRP Metric = 256*[(K1 x BW) + ((K2 x BW)/(256-Load)) + (K3 x Delay) x ((K5/(Reliability + K4))]

    Known as EIGRP “Distance” on the exam.

  3. Hi Rene,

    I understood that if the delay was in ten of microsecond we only sum the delays of the links and if the delay was in microsecond we need to divide the sum on 10 and put the value to formula, and about BW I do not understand why we multiply by 10^7 when I read in Wiki I understand the we do that to make the formula weighted and make measuring units harmonized but I do not understand how ? I mean why 10^7 ? from where this number come ?

  4. Hi Diego,

    That is correct, I just fixed it. Thanks for reporting!
