Practical Ansible 2

Environment variables for network devices

Very often, the complexity of networks is high and the network systems are very varied. For those reasons, Ansible has a huge amount of variables that can help you tweak it so that you can make Ansible fit your environment.

Let's suppose you have two different networks (that is, one for computing and one for network devices) that can't communicate directly, but have to pass through a bastion host to reach one from the other. Since we have Ansible in the computing network, we will need to jump networks using the bastion host to configure an IOS router in the management network. Also, our target switch needs a proxy to reach the internet.

To connect to the IOS router in the database network, we will ...
