Essential Cisco Router Configuration Guide for Beginners

For beginners, the basic configuration of this Cisco router is very necessary in order to learn the next level. In this article I will teach "How to configure a basic dicisco router".

As shown above, here we use the basic dicisco topology, I hope you already understand how to create the dipackettracker topology or you can download the basic topology here.

We will start the initial configuration that we will do on R1, R2, R3, namely:

1. Time Configuration
2. Hostname Configuration 
3. Enable Password Configuration
4. Banner Configuration
5. Password Console and VTY Configuration
6. Interface and Description Configuration

The first step is Time Configuration:

 Router>en  
 Router#clock set 02:00 27 feb 2019  
 Router#show clock  
 2:0:9.861 UTC Wed Feb 27 2019  

The second step is Hostname Configuration:

 Router#conf t  
 Enter configuration commands, one per line. End with CNTL/Z.  
 Router(config)#hos -> tekan tab  
 Router(config)#hostname R1  
 R1(config)#  

Third step Enable Password Configuration:

 R1(config)#enable ?  
  password Assign the privileged level password  
  secret  Assign the privileged level secret  
 R1(config)#enable secret cisco -> the word cisco is the password we use so it's free. 

Fourth step Banner Configuration:

 R1(config)#banner motd #  
 Enter TEXT message. End with the character '#'.  
 "WELCOME TO ROUTER 1"# 

  note : make sure to use the ("") sign for prefix and suffix words and the closing (#) sign to execute the command.  

Step five Password Console and VTY Configuration:

 R1(config)#line console 0  
 R1(config-line)#pass -> Press tab  
 R1(config-line)#password cisco -> the word cisco is the password we use  
                                   so feel free to do anything
 R1(config-line)#login  
 R1(config-line)#exit  
 R1(config)#  

Step Six Interface Configuration and Description:

 R1(config)#int fa0/0  
 R1(config-if)#des -> Press tab    
 R1(config-if)#description "connect to switch-1 fa0/1"
 R1(config-if)#exit  
 R1(config)#int -> Press tab     
 R1(config)#interface s0/0/0  
 R1(config-if)#des -> Press tab     
 R1(config-if)#description "connect to router-2 s0/0/0"
 R1(config-if)#exit  
 R1(config)# 

note : on router two he will configure the description on interface s0/0/0 which leads to router one and s0/0/1 which leads to router three.

Basic configuration on Cisco routers has been completed on router one, now you can continue to router two and router three with the same commands as above.
