RIP Filtering


You are the owner of a Dutch webshop selling Dutch export products. Recently there have been problems on the network, some users had access to certain parts of the network without authorization. You want to use a RIP solution to filter some of the networks. See if you can dutchify this network…


  • All IP addresses have been preconfigured for you.
  • All routers have a loopback interface as following:
  • Configure RIP version 2 on all routers, achieve full connectivity for all networks (including the loopbacks).
  • You notice router WoodenShoe is sending RIP updates to the loopback interface, you have to stop this.
  • Create a prefix-list so router Cheese doesn’t advertise it’s loopback0 interface to router Windmill.
  • Create an access-list so router Tulip doesn’t accept network /24.
  • Create an offset-list so router Windmill doesn’t accept network /24.
  • Change the AD (Administrative Distance) so router WoodenShoe doesn’t place network /24 in its routing table.

It took me 1000s of hours reading books and doing labs, making mistakes over and over again until I mastered all the protocols for CCNA.

Would you like to be a master of networking too? In a short time without having to read 900 page books or google the answers to your questions and browsing through forums?

I collected all my knowledge and created a single book for you that has everything you need to know to become a master of CCNA.

You will learn all the secrets about RIP, filtering networks and more.

Does this sound interesting to you? Take a look here and let me show you how to Master CCNA!

  1. ;D
    Rene, you got an excellent manner to teach. All details are very clear and helped me a lot to understood rip filtering.
    Thanks. 😀

  2. Hi, contains topology,
    but without configured IP addresses,


  3. Wow, this stuff gets pretty complicated even in using RIPv2. I thought it was really interesting how you were able to apply the ACL to both interfaces by integrating it in with the distribute-list command in router configuration mode. Awesome. Lots of flexibility with those ACL’s. So many different ways to do something, it’s almost endless. Thank you for the video!!! 🙂 Also, this brings up another CCNA level question. I noticed that you really didn’t apply the last ACL that you did in the video to any particular interface. Could I safely assume that it then applies to every interface in all directions on that particular router?

    1. Which ACL on which router do you mean? Otherwise I have to browse through all configs or watch my own video again 😛

      If you apply something in "router" mode than it is applied globally and not to a certain interface.
