Network Automation

An Ansible like Network Automation Framework, Using Python OOP and Netmiko to interface with Cisco IOS, VyOS, EdgeOS network devices.

Usage

Example 1: Getting Basic Device Information from a VyOS Router

Importing the class from the package.

from net_automation import net_automation

Creating an instance of the VyOS class, with specified parameters.

router_1 = net_automation.Vyos(
    "router-1.com",                                                      # Hostname/IP
    "username",                                                          # Username
    "",                                                                  # Password   
    True,                                                                # Boolean switch for using SSH Keys. (password not needed if True)
    "/home/user/.ssh/id_rsa",                                            # SSH Key file location
    "")                                                                  # Secret (left empty, as Cisco Only)

Establishing the SSH connection to "router_1" and getting interfaces.

router_1.init_ssh()                                                      # Creates the SSH connection to the VyOS router

print (router_1.get_interfaces())                                        # Returns Interfaces from the VyOS router

Codes: S - State, L - Link, u - Up, D - Down, A - Admin Down
Interface        IP Address                        S/L  Description
---------        ----------                        ---  -----------

wg12             172.22.132.170/30                 u/u  p2p_usman 

Getting a traceroute to "8.8.8.8".

print (router_1.get_route("8.8.8.8"))                                   # Returns traceroute to specific IP

Storing returned route table and configuration in variables.

configuration = (router_1.get_config())                                
route_table = (router_1.get_route_table())

Example 2: Generating and Deploying Configurations to a VyOS Router.

###.py file

from net_automation import net_automation

net_automation.Vyos.deploy_yaml("router.yml")

Executing the Python script should generate and deploy configs, based on the contents of the YAML file.

Example 3: Backing up device configurations.

Creating instances CiscoIOS and EdgeOS classes, for Cisco switches and Ubiquiti switches.

cisco_2960 = net_automation.Cisco_IOS(
    "cisco-2960.lan",
    "usman",
    "password", 
    False, 
    "", 
    "ciscosecret")

cisco_3560 = net_automation.Cisco_IOS(
    "cisco-3560.lan",
    "username",
    "password", 
    False, 
    "", 
    "ciscosecret")

ubiquiti_erx = net_automation.EdgeOS(
    "ubiquiti-erx.lan", 
    "username", 
    "", 
    True, 
    r"C:\Users\Usman\.ssh\id_rsa", 
    "")

ubiquiti_er4 = net_automation.EdgeOS(
    "ubiquit-er4.lan", 
    "usman", 
    "", 
    True, 
    r"C:\Users\Usman\.ssh\id_rsa", 
    "")

For loops that get device configurations and writes them to external files.

cisco_switches = [cisco_2960, cisco_3560]

for device in cisco_switches:                                                               # iterates through the "cisco_switches" array and:
    to_write = Cisco_IOS.get_all_config(device)                                             # stores the outputs from method in the "to_write" variable
    Cisco_IOS.write_file(device, to_write, "")                                              # writes the output to new files                            

ubiquti_routers = [ubiquiti_erx, ubiquiti_er4]

for device in ubiquti_routers:                                                              # iterates through the "ubiquiti_routers" array and:
    to_write = Vyos.get_config(device)                                                      # stores the outputs from method in the "to_write" variable
    Main.write_file(device, to_write, "")                                                   # writes the output to new files
