Control Plane Policing


You are the security office for the national security team in the Netherlands. Recently you did everything in order to protect the data plane of your routers. The only you haven’t done yet is securing the control plane for your routers…


  • All IP addresses have been preconfigure for you.
  • EIGRP has been configured for connectivity.
  • Use control place policing to solve everything.
  • Configure router Harbor so ARP traffic to the control plane is limited to 75 packets per second.
  • Configure router Harbo so telnet traffic from router Terminal is dropped.

  1. I need some help please, I am trying to extract files from a zipped folder, when I try, it keeps asking me for a ‘password’.

    I have tried my GNS3 password but that does not work.

    Can someone help URGENTLY……

    Many Thanks


    1. Hi Gurmit,

      Just saw your other post, there’s no password on the ZIP files. I would recommend to try another ZIP extractor like winrar.


  2. I wish I were introduced to this website far much earlier. Because then I would have multiple CCIEs by now.

    This is a wonder is an overly helpful site. Appreciate it!!!!!

  3. Yeah man there is no password on any of these files man. The licence of the zip software you are using could be out of date. Try using a windows default Zip software.
