Practical Network Automation - Second Edition

Dynamic configuration updates

In this example, we will try to update the configurations on certain interfaces that are not static. There are scenarios where, on a scalable environment, we need to bulk update certain configs, or even generate and push new configs based upon the discovered inventory.

Using this approach, we use the technique on identifying whether the Loopback45 interface is available on a given router, and additionally, if the description of that particular interface contains the test interface created text. If these conditions match, then we need to update the description for that particular interface to Mgmt loopback interface and finally validate the output.
