Information
If you enable this command, clients can login without a password prompt. This provides two levels of
authentication:
• rhost-authentication is done with the file specified in the ip ssh rhostfile command
• checking client host-keys is done with the file specified in the ip ssh pub-key-file command
If you execute no ip ssh rsa-authentication enable, host-based authentication is disabled.
