![[Day #81 Pyats Series] Building pyATS test suites for 1000+ devices using pyATS for Cisco [Python for Network Engineer]](https://networkjourney.com/wp-content/uploads/2025/08/Building-pyATS-test-suites-for-1000-devices-using-pyATS-for-Cisco.png)
Introduction on the Key Points When you manage a network of 1000+ Cisco devices, manual health checks, configuration validation, and performance monitoring become impossible to do efficiently. Logging into each router, switch, or firewall individually wastes countless hours and is prone to human error. That’s […]

Introduction on the Key Points Welcome back to Day 44 of our 101 Days of pyATS Series, where we dive deep into vendor-agnostic network automation and validation techniques. Today, we’re focusing on one of the most critical aspects of inter-domain routing: Cross-checking BGP route attributes […]
![[Day #29 PyATS Series] Loopback IP Reachability Validation (Ping Tests) Using pyATS for Cisco [Python for Network Engineer]](https://networkjourney.com/wp-content/uploads/2025/08/Day29-PyATS-Series-Loopback-IP-Reachability-Validation-Ping-Tests-Using-pyATS-for-Cisco.png)
Introduction In large-scale enterprise and service provider networks, Loopback interfaces play a crucial role in routing protocols, management access, and network stability. Ensuring continuous reachability of loopback IPs is a key part of proactive network monitoring. Manual ping testing can be tedious and prone to […]
![Day #16 PyATS Series] Automating Common CLI Commands (Multi-Vendor) using pyATS for Cisco – Python for Network Engineer](https://networkjourney.com/wp-content/uploads/2025/07/Day16-PyATS-Series-Automating-Common-CLI-Commands-Multi-Vendor-using-pyATS-for-Cisco-–-Python-for-Network-Engineer.png)
Introduction Welcome to Day #16 of the 101 Days of pyATS (Vendor-Agnostic) series. In this lesson, we focus on automating common CLI commands across multi-vendor environments (Cisco IOS-XE, Arista EOS, Palo Alto PAN-OS, Fortinet FortiOS) using pyATS. As networks grow more complex, engineers often need […]
