Today we practice a little bit of the commands...

Dear students, Today's lesson is in English. Let's see what they mean by the text here;

You will practice and be assessed on the following skills: Configuration of initial IOS device settings and important design and calculation of IPv4 addressing then configuration of IOS device interfaces including IPv4 and IPv6 addressing when appropriate Addressing of network hosts with IPv4 and IPv6 addresses. Enhancing device security, including configuration of the secure transport protocol for remote device configuration interfaces  configuration of a switch management interface Requirements by device: school router. Configuration of initial router settings interface configuration and IPv4 and IPv6 addressing device security enhancement device hardening  secure transport for remote configuration connections as covered in the labs. Backup of the configuration file to a TFTP server Administration Switch: Enabling basic remote management by Telnet PC and Server hosts: IPv4 full addressing IPv6 addressing.

The name for the keys will be: Middle.cisco.local
Choose the size of the key modulus in the range of 360 to 2048 for your
General Purpose Keys. Choosing a key modulus greater than 512 may take
a few minutes.

How many bits in the modulus [512]: 1024
% Generating 1024 bit RSA keys, keys will be non-exportable…[OK]
