Step 1: Connect the equipment

Connect Router 1 and Router 2 with a serial cable connecting both Serial 0/0/0 interfaces as shown in the topology diagram.

Step 2: Perform basic configuration on Router 1

Connect a PC to the console port of the router to perform configurations using a terminal emulation program. On Router 1, configure the hostname, IP addresses, and passwords as provided in the addressing table. Save the configuration.

Step 3: Perform basic configuration on Router 2

On Router 2, configure the hostname, IP addresses, and passwords as provided in the addressing table. Save the configuration.

Step 4: Show the details of Serial 0/0/0 interface on R1

Enter the command show interface serial 0/0/0 to view the details of the interface.

Step 5: Show the details of Serial 0/0/0 interface on R2

Enter the command show interface serial 0/0/0 to view the details of the interface.

Step 6: Turn on PPP debugging

Turn on the PPP debug function on both routers by entering debug ppp negotiation at the privileged EXEC mode prompt.

Step 7: Change the encapsulation type

Change the encapsulation type to PPP by entering encapsulation ppp at the interface Serial 0/0 configuration mode prompt on both routers.

Step 8: Show the details of Serial 0/0/0 interface on R1

Enter the command show interface serial 0/0/0 to view the details of the interface.

Step 9: Show the details of Serial 0/0/0 interface on R2

Enter the command show interface serial 0/0/0 to view the details of the interface.

Step 10: Verify that the serial connection is functioning

Ping from R1 to R2 to verify that there is connectivity between the two routers.

Step 11: Reflection

  1. What command allows you to view the details of a specific interface? Jawaban: show interface serial 0/0/0 (or whichever interface you select).
  2. When should you use the debug function in a router? Jawaban: when you want to troubleshoot or to view what is occurring in real time on the network. Caution should be used to minimize the negative impact debugging has on network performance.
  3. What is the default serial encapsulation on a Cisco router? Jawaban: HDLC
