Using Telnet ----- could you help how can I do this lab on the cisco packet tracer application???

Secure Shell was covered in Chapter 6, and it is what you should use for remote access into a Cisco device. However, the Cisco objectives cover Telnet configuration. 1. Log into your router and go into privileged mode by typing en or enable. 2. From RouterA, telnet into your remote router (RouterB) by typing telnetip_address from the command prompt. Type exit to disconnect. 3. Now type in RouterB's IP address from RouterA's command prompt. Notice that the router automatically tries to telnet to the IP address you specified. You can use the telnet command or just type in the IP address. 4. From RouterB, press Ctrl+Shift+6 and then X to return to RouterA's command prompt. Now telnet into your third router, RouterC. Press Ctrl+Shift+6 and then X to return to RouterA. 5. From RouterA, type show sessions. Notice your two sessions. You can press the number displayed to the left of the session and press Enter twice to return to that session. The asterisk shows the default session. You can press Enter twice to return to that session. 6. Go to the session for your RouterB. Type show users. This shows the console connection and the remote connection. You can use the disconnect command to clear the session or just type exit from the prompt to close your session with RouterB. 7. Go to RouterC's console port by typing show sessions on the first router and using the connection number to return to RouterC. Type show user and notice the connection to your first router, RouterA. 8. Type clear line line_number to disconnect the Telnet session.
