  3. hi rene if I was trouble shooting a failed eigrp neighbour is there a show command to see if the key chains are configured ok or do I just have to look at the debug output for this thanks keep up the good work as i'm almost ready to sit my ccnp route exam because of you easy to understand site

  4. Hi Shaun,

    There is a "show key chain" command but personally I never use it. The debug will help you to figure out there is an authentication problem. The quickest method to fix it is to check the key chain in the running-config, make sure you use the same keys on both routers. Also check the interface if EIGRP authentication has been enabled.

    Good luck with the exam!

    Is there any way to hide or restrict users from viewing the KEY (other than by assigning views or privilege levels) ?
