  1. Hi Mario,

    The first two bits have to be 10 so that means the following range is class B:

    10000000 - 10111111

    Or in decimal:

    128 - 191


  2. Thanks Rene,

    When I configure prefix-list and use it in the distribute-list inside EIGRP configuration I notice that we have three options:

    • gateway Filtering incoming address updates based on gateway
    • in Filter incoming service updates
    • out Filter outgoing service updates

    The last two are clear but I did not understand the first one ? Can you explain it to me please ?

  3. Regarding the prefix that are covered in &
    Why does it stop at subnet #6 for /3 and #19 for /5

    256 – 224 = 32 subnets
    256 – 248 = 8 subnets

    So for /3 it looks like this:

    Subnet #1:
    Subnet #2:
    Subnet #3:
    Subnet #4:
    Subnet #5:
    Subnet #6:
    And for /5:

    Subnet #1:
    Subnet #2:
    Subnet #3:
    Subnet #4:
    Subnet #5:
    Subnet #6:
    Subnet #7:
    Subnet #8:
    Subnet #9:
    Subnet #10:

  4. Ok, Hi everyone just joined the site.

    I want to make sure that my brain understands this. It’s like you slice and dice and hopefully everything comes out right. So say I have this already as my prefix list: le 32

    Now say I want to include another network. So I want the following two networks in one prefix-list. and, I want these covered by one prefix list.

    So I figure that this will fit within the scope of these two networks.

    2 will be size of subnets:

    0, 2, 4, 6, 8, 10
    12 and 13 — this fits just right.
    14, 16, 18 et

  5. I was so confused by this at first. I know its simple but its also a brain teaser for some reason.
    first I pulled up my boson subnet tool its free tool by the way on the Boson.com (just need to create an account) website. At first I was thinking that first two bits mean the first two spots _ _ thinking it could be anything from 0 to 192 that it did not matter if it was a zero or a one. However after putting into the subnet calculator it helped me to see.

    The next really helpful thing for me was when I went ahead and enabled the command with distribute-
