EVPNsta

EVPNsta is a Python library designed to simplify the testing and validation of Ethernet VPN (EVPN) network configurations. It allows network engineers to programmatically interact with network devices that support EVPN, enabling automated testing of various EVPN functionalities such as MAC address learning, route advertisement, and traffic forwarding. The library aims to reduce the complexity and time involved in manual EVPN testing, making it more efficient and repeatable.

The core functionality of EVPNsta revolves around its ability to establish NETCONF or gRPC sessions with network devices. Once connected, it can retrieve EVPN operational state data, including MAC address tables, EVPN routes, and VNI configurations. Users can then write scripts to assert expected states, compare configurations, and simulate specific network scenarios. This is particularly useful for continuous integration and continuous deployment (CI/CD) pipelines in network automation.

EVPNsta supports common EVPN use cases and protocols. It can be used to verify the proper functioning of multi-tenant networks, VXLAN overlay tunnels, and integrated routing and bridging (IRB) scenarios. The library's open-source nature encourages community contributions, allowing for broader device support and feature development over time. By abstracting away device-specific command-line interfaces and data models, EVPNsta provides a unified and programmatic approach to EVPN testing.
