  1. 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

  2. Hi

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



  3. Hi again Rene,

    Why cisco decided to use this “ip authentication mode eigrp AS_NUM md5” command for enabling eigrp authentication instead of using “ip eigrp AS_NUM authentication mode md5” ??

    In the other word what is the wisdom of using “ip authentication mode eigrp AS_NUM md5” command instead of the “ip authentication eigrp AS_NUM mode md5” command where it seems more clearly ??

  4. Hello Hussein

    Cisco commands are implemented using a specific hierarchy. When you type the command ip eigrp ?, the resulting commands all have to do with EIGRP and its functionality. They are limited to routing EIGRP and nothing else. However, authentication is a different entity and must be placed within a different category. This is why the commands fall under the ip authentication keywords even though the authentication is being configured for EIGRP. Anything under the ip authentication ? will belong to the authentication functionality of the router.

  5. Hi @shaunasromamad,

    I’m a bit late but I want to add this for the future.
    If you use show running-config you won’t see if you inadvertently typed a space in the password.
    show key chain on the other hand will show the configured key-string in quotation marks ("MY_Key_String ") so on a misconfiguration you will see "MY_Key_String " for example.

    Best regards,
