This document discusses how Puppet and Cumulus Networks can help with network automation. It provides an overview of Puppet's capabilities in defining and enforcing infrastructure configurations. Cumulus Networks offers an open network operating system that can work with Puppet for zero-touch provisioning and standardization. The document includes demos and next steps for learning more about the Puppet and Cumulus Networks integration.

16. Network OS installer discovery and execution
§ Like a pre-installed BIOS, PXE, and kickstarter in one
§ Implemented through Linux kernel with BusyBox
Donated to the Open Compute Project (OCP)

ONIE

17. Cumulus Linux OS Installation with ONIE
§ Look for installer (“discover”)
§ Locally, e.g. USB if available
§ Over the network on eth0
• DHCP, IPv6 neighbor, TFTP
§ Search for file name and execute

18. ▪ Handles network interface dependency
using dependency graphs
▪ Uses topological sort to order network
interface configurations
▪ Provides options and tools to query and
execute interface configuration in
dependency order
▪ Built-in devices support
ifupdown2 implicitly recognizes vlan and
physical interfaces that appear as
dependents and does the required
minimal configuration to get them up: No
need to specify `iface swp1.1000` in the
example
