  1. Dear Anthony,

    Thank you again for the series. That would be great if CCIE Security series could be done in CBT Nuggets after R&S. I’m strongly looking forward for it.

  2. Dear Anthony,

    I saw the NTP nugget.

    I did this config in GNS3:

    Server:
    c#ntp master 1

    Client:
    c#ntp authentication-key 1 md5 cisco
    c#ntp authenticate
    c#ntp trusted-key 1
    c#ntp server

    It worked while server does not have key.

    What do you think about it?

    1. Server:
      c#ntp master 1

      Client:
      c#ntp authentication-key 1 md5 cisco
      c#ntp authenticate
      c#ntp trusted-key 1
      c#ntp server IP

  3. Dear Anthony,
    Thank you for your reply.

    Sorry; I missed “key NUMBER” after “ntp server IP” and although I had other authentication commands, ntp formed without authentication. It is odd.

    One more thing:

    I did the config you suggested but it is not worked.

    Here it is:
    R2:
    c#ntp authentication-key 1 md5 cisco
    c#ntp master 1

    R1:
    c#ntp authentication-key 1 md5 cisco
    c#ntp authenticate
    c#ntp trusted-key 1
    c#ntp server 12.12.12.2 key 1

    R1#sh ntp associations detail
    12.12.12.2 configured, ipv4, authenticated, insane, invalid, unsynced, stratum 16

    I added “ntp trusted-key 1” on the server and then it worked.

    I found that without “ntp trusted-key 1” on the server it is not working and with it, it works immediately.

    I have tested it many times with three different IOSes.

    Here is the working config for me:
    R2:
    c#ntp authentication-key 1 md5 cisco
    c#ntp trusted-key 1
    c#ntp master 1

    R1:
    c#ntp authentication-key 1 md5 cisco
    c#ntp authenticate
    c#ntp trusted-key 1
    c#ntp server 12.12.12.2 key 1

    R1#sh ntp associations detail
    12.12.12.2 configured, ipv4, authenticated, our_master, sane, valid, stratum 1

    What do you think about it?
