With our hosts, host connection, & login informaiton defined and our banner configuration playbook written we can run the playbook. The banner text can be pulled from a variable in another file or a document in another directory as well.Use # signs to comment out lines you want Ansible to ignore.This playbook includes 3 modules, one for Cisco IOS, IOSXR, and NXOS.# nxos_banner module for Cisco NXOS devices # iosxr_banner module used for IOSXR Cisco Devices State: present # Current existential state of the banner Text: | # The text to be used for the banner Ios_banner: # The name of the module to useīanner: login # The type of banner such as login or exec # text can be defined here or as a variable called from another place. # Banner choices: login / motd / exec / incomin / sip-ppp # ios_banner module used to define banners and messages of the day on Cisco IOS devices Tasks: # Anything below this point are tasks to be run Hosts: cisco # Define the group of that exist in the inventoryĬonnection: network_cli # Connection type- network_cli for IOS devices
name: Configure motd and banner # Purpose of the playbook #YAML files are designated by the 3 - dashes To begin, I create a banner_playbook.yml file under the playbooks directory Once our inventory is defined with the hosts we want to run Ansible against, we have to create a playbook comprised of tasks to complete.įor this example we will be configuring a banner on a Cisco IOS device.

Here we need to identify the information Ansible will use when attempting to connect to the device using SSH:Īnsible_network_os=ios # The type of Operating SystemĪnsible_become=yes # Permissions upgrade 'yes' or 'no'Īnsible_become_method=enable # Enter enable modeĪnsible_become_password=password # Enable password Router1 ansible_host=192.168.56.130 # Defined by naming conventionĪnsible also recommends specifying your host groups connection and credential information in the host file in the form of like below. We can define hosts by IP, by “Router1 ansible_host=192.168.56.130”, or by hostname if DNS is configured. This allows us to call multiple hosts at once by defining one group in our playbook. We define a group of hosts disgnated in brackets such as. Group_vars/ # Variables to be called from playbooksįirst we have to define our host that we want to configure in a hosts file. I prefer to set up my directory like the one below:Īnsible_project/ # Top level ansible folder The recommonded best practice for setting up the directory structure can be found in Ansible’s docs: Best Practices however for this post, our directory is much simpler. Preparing Ansible to Configure a Cisco Routerīefore we can begin we will have to set up our Ansible directory.

Ansible’s modules are pre-written unites of code designed to accomplish certain tasks within a playbook. Ansible has modules written for many existing network products such as Cisco, Juniper, Palo Alto, etc. Ansible and Networkingĭue to Ansible’s ability to push configuration changes using SSH, Ansible can be used on almost any networking device.
In this post we will go over a simple configuration of a Cisco IOS device using Ansible running on a Ubuntu VM and a Cisco device running in GNS3.

Auotmating Cisco IOS devices with AnsibleĪnsible is an IT automation software used to simplfy routine tasks such as provisioning, configuration, app deployment, security automation, and much more.
