RIP Authentication Key

RouterOS Forwarding Protocols

Can someone explain when RIP Interface Authentication Key is used (see attached picture). According to the debug log, authentication is using password from keychain.

Here are the steps i have done.

  1. Define a key chain with a name.
  2. Define the key on the key chain.
  3. Define the key ID.
  4. Specify the password or key-string to be used in the key.
  5. Enable authentication on an interface and specify the key chain to be used.
  6. Specify whether the interface will use plain text or MD5 authentication.
  7. Define the networks to advertise.
