configuring a router using python script automation can greatly simplify the process of managing network devices. in order to automate router configuration, you will typically use a library such as netmiko, which provides support for managing network devices via ssh.

here is a step-by-step tutorial on how to configure a router using python script automation with netmiko:

step 1: install netmiko library
make sure you have netmiko installed on your system. you can install it using pip:



step 2: import the necessary modules
in your python script, import the necessary modules including connecthandler from netmiko, and getpass for securely entering the router password:



step 3: define router connection parameters
set the connection parameters for the router such as ip address, username, and password. you can also prompt the user to enter the password securely using getpass:



step 4: establish an ssh connection to the router
create an ssh connection to the router using the connecthandler function from netmiko:



step 5: send configuration commands to the router
now you can send configuration commands to the router using the send_config_set method. for example, configuring an interface with an ip address:



step 6: save the configuration changes
finally, save the configuration changes made to the router:



step 7: close the ssh connection
after completing the configuration, it's good practice to close the ssh connection to the router:



that's it! you have now automated the configuration of a router using python script with netmiko. you can expand on this example by adding error handling, logging, and more complex configuration tasks.
