Episode Description:
If you've discovered netmiko and learned how to send and receive CLI commands from your network devices with Python, you're likely wondering "is this the best we have for network programmability?" Thankfully, the future of network automation is not a land of crafting CLI templates and parsing the unstructured clear text output with regular expressions.
In this session, we'll explore NETCONF, the widely available IETF standard for NETwork CONFiguration, and the YANG models that are providing consistent representations of concepts like "Interfaces" and "Access Control Lists." You can think of NETCONF and YANG as the next generation of SNMP and MIBs, and they were built to make network configuration through network orchestration systems and custom scripts an achievable reality for every engineer and organization.
We'll look at how to use these tools to retrieve and edit configurations, explore the operational status of a network device, and how they can be used to provide consistent control and interfacing to multiple network platforms.
