Implementación del provisionamiento automático de configuraciones (Network Automation) en infraestructuras multivendor con Ansible.

Abstract

The aim of the titling work was to implement the automatic provisioning of configurations (Network Automation) in multivendor infrastructure with Ansible. GNS3 was used as an emulation tool to implement the different topologies. By using GNS3, by default, your virtual machine is also used through VM Ware; its use is to install the automation tool and the networking platforms that are used, such as CISCO, ARISTA and JUNIPER, the selection of these platforms was based on a comparison of different features (Benchmarking). When performing the simulation, different topologies are used with configurations of BGP, VLANS, MPLS in the network devices such as routers, switches and firewall. The central node, through Ansible is responsible for applying all configurations to network devices through the different directories, files, playbooks (which are written in YAML) and templates (which are written in JINJA2), each of these meets a specific role to apply the configuration tasks to the secondary node. It is concluded that Ansible is an "agentless" or "agentless" automation tool that does not use databases, does not use daemons and no external agent, therefore, it does not leave any vulnerability in the equipment, unlike other tools that use external agents such as Chef and Puppet. When using Ansible in the different network topologies to more than thousands of network devices it is recommended to have a well-structured and ordered documentation of all the playbooks and templates for the network. One of the tools used to carry such documentation is Sublime Text 3, which is a text editor and source code editor that is written in C ++ and Python that provides the ability to support different programming languages.
