  1. This is probably the most amazing explanation I have come across in my process of certifying as CCNA. It’s simple, straight to point and easy to understand. I’ve always thought that switching and routing isn’t difficult to understand, it’s just awfully explained by lecturers and people in general but you definitely got a talent to make complex things easy. Keep it up.

  2. Ahh! This is simply awesome Rene.
    I have come across your lessons. They are so easy to understand. Keep it up.

  3. In my example there is only 1 router that is running EIGRP and RIP at the same time. When you have two routers doing redistribution, it is possible that you get a scenario like this:

    Prefix from routing protocol A > B > A

    This is a problem that can cause routing loops or sub-optimal routing. Imagine that we have prefix in EIGRP, by default it has a AD of 90.

    Once it is redistributed into RIP, it has an AD of 120.

    When we redistribute it back into EIGRP, the AD is 170 (external).

    Since 170 (external) is higher than 90 (internal), EIGRP will never

  4. Hi Deepak,

    You can set a default seed metric globally with the “default-metric” command. That’s what I used for RIP in that example.

    It’s also possible to specify the seed metric when redistributing. For example:

    R1(config)#router rip
    R1(config-router)#redistribute ospf 1 metric 5

    This will accomplish the same thing.


  5. Hello Rene,
    Thanks a lot for you amazing explanation,
    I still have a question how to decide what is the value of K1 to use.
    or if I need to troubleshoot the K1 value if it’s correct or not, what to look for?
    Thanks in advance.
