This article serves as an example to explore different strategies for configuring a feature on network devices using Ansible. Specifically, we will focus on configuring NTP on Cisco IOS devices, although the discussions here can be generalized.

This article explores how to optimize the provisioning of a hundred Cisco XR devices so that they are configured with minimal human intervention. Depending on the context, the devices might be shipped directly from the factory and configured automatically on-site, or more likely, they could be automatically configured in a lab environment, verified, and then shipped for installation.

Ansible Navigator is a container-based textual interface designed to manage various components of Ansible. In essence, it serves as a wrapper, providing a unified interface to the Ansible ecosystem. Initially, the use of Ansible Navigator does not require container usage; thus, we will use the --ee=false parameter.

In my opinion, one of the less understandable constructs in Ansible concerns loop management. If we then talk about nested loops, the situation becomes even more complex. In this short post, we’ll see the recipes for:

I have been involved in automation since around 2004, when I was managing nearly 200 nodes on the AlphaServer. Specifically, I was responsible for the hardware aspect. It may seem straightforward, but it’s important to consider that there was a mini operating system running under Unix that checked the connected components, detecting both critical and non-critical errors.
