Cisco Networking Lab 1 - Router Basic Configuration


We have learned how to install GNS3 in the previous article and today we are going do a Cisco Lab. In this article, we are configuring a cisco router.
Cisco Router – Initial Configuration
Configure the Router Host Name.
Configure the Passwords
Configure the Banner Messages / Message of the Day MOTD
Verify the configuration
Device Configurations - R1, R2,
I have placed 2 Router, 2 Switch and 2 PC in the GNS3 workspace and connected each other with suitable cables.
Configure Router- R1
Step 1: Configure the router hostname
R1#config t
R1(config)# hostname The_WanTricks_R1
Step 2: Configure the privileged mode and secret passwords
The_WanTricks_R1#config t
The_WanTricks_R1(config)#enable password thewantricks
Configure encrypted privilege password as twt987
The_WanTricks_R1(config)#enable secret twt987
Step 3: Configure the console password
The_WanTricks_R1(config)#line console 0
Enable the password ‘twt987’ require at login time
The_WanTricks_R1(config-line)#password twt987
Step 4: Configure the vty password to allow Telnet access to the router
The_WanTricks_R1(config)#line vty 0 4
The_WanTricks_R1(config-line)#password twt1234
Step 5: Set password encryption, MOTD banner
We have configured two passwords above but it storing as only in clear text format, so others can read the passwords when use ‘show running-config’ command, but if encrypt the passwords with other formats then the security risk can avoid easily.
Password Encryption
The_WanTricks_R1(config)#service password-encryption
Use the ‘show running-config’ command again and verify the encryption status
Setup MOTD banner message
The banner is mainly used as a warning to the unauthorized person who are trying to access the device.
The_WanTricks_R1(config)#  banner motd $This device is managed by$
To verify the MOTD banner, Log out of the router by typing the exit command twice, then log in again by typing enable command.
Topic Conclusion
We have configured the router with basic commands. These are the initial configuration and will post advanced sections in the coming articles.
