netsim-tools are bringing infrastructure-as-code concepts to networking labs. You'll describe your high-level network topology and routing design in a YAML file, and the tools in this repository will
Instead of wasting time creating lab topology in a GUI and configuring boring details, you'll start with a lab preconfigured according to your specifications.
More details in release notes.
netlab create : Creates a full-blown network topology, Vagrantfile and Ansible inventory from a simple list of nodes and links. More details
netlab initial : Using topology data generated by netlab create and default device configuration templates configures common device parameters, protocols that should have been enabled (LLDP, OSPF, IS-IS, BGP, SR-MPLS), enables interfaces, and configures IP addresses on interfaces. More details
netlab config : Applies any Jinja2 configuration templates to network devices.
netlab collect : Using Ansible fact gathering or other device-specific Ansible modules, collects device configurations and saves them in specified directory (default: config).
netlab connect : Use SSH or docker exec to connect to a lab device using device names, management network IP addresses (ansible_host), SSH port, and username/passwords from Ansible inventory. Ideal when you use centralized Vagrant environments and want to connect to the devices while being in playbook development directory.
enable-lldp.sh : Given libvirt network name, change group_fwd_mask for the corresponding Linux bridge to enable LLDP passthrough across the Linux bridge.
