Third Exercise with Packet Tracer

In this lesson we had to do two exercises. In 6.4.1.3 there is a computer connected to a router and we had to configure the router. In 6.4.3.3 there is a network of some computers, two switches and a router but some of the computers are not connected to the network. We had to figure out why.
 

Exercise 6.4.1.3

• To configure the router the terminal is needed. To see the running configuration we use the router# show running-config command. Now we are able to answer the questions in Step 2 c.
• What is the router’s hostname? Router
• How many Fast Ethernet interfaces does the Router have? 4
• How many Gigabit Ethernet interfaces does the Router have? 2 
• How many Serial interfaces does the router have? 2
• What is the range of values shown for the vty lines? 0 to 4

•  If you type in sh startup-config the router will tell you, that it is not present because the startup-config is not yet configured.
• In Part 2 we had to define new passwords.

• Router(config)#hostname R1:
  
  
  Changes the name of the router. (Can also be done in the configuration dialog)
  
  R1(config)#line con 0:
  This command changes the config line.
  
  R1(config-line)#password letmein:
  To declare the password and set it to "letmein". Afterwards you login and exit so that the password is set.
  
  

  R1(config)#password enable cisco
  This is to declare the password to enter the privileged mode. It is not encryped.
  
  R1(config)#password secret itsasecret
  For a encryped password for the privileged mode you need this command.
  
  R1(config)#banner motd #Unauthorized acces is strictly prohibited. #
  You can set the Message of the day by using this command. It will be shown if you want to log in as seen in the picture below.
  

  

  
  
  
• The startup-config is saved in the NVRAM  with the command R1(config)# copy r s 

 

Exercise 6.4.3.4

• Task 1: Fill the table shown below
  
  
  
   
• Task 2: Testing connections and finding solutions for not-connected devices.
