Adding New Non-Configurable Device¶
Adding a new non-configurable device is almost as easy as adding a virtualization provider for an existing device.
Here’s what you have to do:
Choose a short name for the new device type (examples: ios, eos, cumulus…)
Select one or more virtualization providers you want to work with.
Build a Vagrant box from whatever image your vendor supplies. It’s not as hard as it sounds, there are tons of recipes on codingpackets.com. If you want to build a container to use with containerlab, please refer to their documentation.
Document the process in a blog post or GitHub gist.
Add device parameter file
netsim/devicesdirectory (see the next section for details).

Adding New Device Settings¶
Every device parameter file must have a description – a short string describing the device
For every supported virtualization provider, define device box (or container) to use with image parameter within the provider dictionary (example libvirt.image).
Define interface names as used by the new device with interface_name, mgmt_if and optionally ifindex_offset (more details)
Add group_vars dictionary with Ansible variables specific to the new device. Set at least the ansible_connection and ansible_network_os variables. ansible_user and ansible_ssh_pass are highly recommended unless you’re using docker connection type. The group variables are required even if you don’t plan to implement a configurable device; they are used by netlab connect command to figure out how to connect to a device.
Example: Mikrotik RouterOS
interface_name: ether%d mgmt_if: ether1 ifindex_offset: 2 libvirt: image: mikrotik/chr group_vars: ansible_network_os: routeros ansible_connection: network_cli ansible_user: admin ansible_ssh_pass: admin
