Philippe Bureau enhanced the Vibhu-gslab/avd repository by implementing template-driven underlay Ethernet interface support for l3_edge and core_interfaces. Leveraging Ansible, Jinja2 templating, and YAML, he enabled the use of custom templates to generate interface descriptions and optional tags, aligning configuration files and inventory variables with new interface types. Philippe updated documentation to clarify template context, supporting easier adoption and ongoing maintainability. This work reduced manual configuration edits and accelerated onboarding of new interface types, resulting in more flexible and scalable network deployments. The depth of the solution reflects a strong grasp of network automation and configuration best practices.
