pyATS Easypy enables the execution of multiple test scripts organized through a job file, with built-in logging and reporting features. It is commonly used in production environments where structured test execution and result archiving are required.
DetailsMPLS central services VPN, also known as MPLS VPN shared services, is a topology where multiple customer VPNs securely access shared services like voice gateways or Internet access, while traffic isolation is maintained through route-target filtering and route leaking.
DetailsChange configuration with pyATS: pyATS is primarily a testing framework, but it can also be used to push configuration to devices. In this section, we show how to combine pyATS with Jinja2 templates and YAML data to apply device-specific configurations dynamically.
DetailsMPLS VPN hub-and-spoke topology is the focus of this lesson. In this design, customer branch sites communicate exclusively with the central office, not with each other. We will configure this topology using route targets (RTs), as introduced in the previous lesson.
Detailsaetest loop.mark is a feature of AEtest in pyATS used to mark a testcase or test section for iteration. It is often applied with different parameters and is particularly useful when you want to run the same test logic multiple times with different input values.
DetailsRoute Target (RT) in an MPLS VPN, advertised via MP-BGP between PE routers, plays a key role in defining customer VPN topologies. This section explores how RTs are designed to support various topologies, including full-mesh, hub-and-spoke, central services, and extranet models.
DetailspyATS aetest is a Python-based testing framework designed for writing and executing structured network test scripts. It allows you to create reusable test cases to verify that your network devices and configurations are functioning as expected.
In this section, we’ll introduce the basics of aetest, explore its structure, and walk through a simple example to get started.
MPLS VPN control plane and data plane understanding is essential to grasp how MPLS VPNs operate. The control plane, powered by LDP and MP-BGP , are responsible for building and exchanging routing and label information that determines how traffic should flow across the network. In contrast, the data plane handles the actual forwarding of packets within the MPLS network, using the labels and paths established by the control plane.
