You can also run network management software and even some network services products (for example, NetScaler) as custom Linux containers.

The support level of a platform is defined as:

  • full – a core contributor is regularly implementing new features. We run a full suite of integration tests for every release that could impact the device behavior (for example, due to changes in configuration templates).

  • best effort – while a core contributor might still work on the platform, we don’t run integration tests (usually due to limited availability of the VM/container image). YMMV.

  • minimal – don’t expect too much[2]. What you see is pretty much what you’ll get (and in many cases, it did not go through integration tests).

  • end-of-life – these platforms are still part of netlab package because the storage prices keep falling.

Tip

Use netlab show devices to display the up-to-date device list and device support levels.

Most devices behave as routers (or layer-3 switches); the following devices can take multiple roles or behave as IP hosts:

Notes:

Supported Virtualization Providers

netlab create can generate configuration files for these virtualization providers:

  • vagrant-libvirt, including support for veryisolated private networks and UDP point-to-point tunnels.

  • Containerlab

  • External – meta virtualization provider that allows you to configure external physical or virtual devices with netlab

You cannot use all supported network devices with all virtualization providers. These are the supported combinations (use netlab show images command to display the current system settings); daemons always run in containers.

Configuration Deployment Mechanisms

netlab can use a variety of device configuration deployment mechanisms:

Method

Description

daemon
configurations

Daemon configuration files are generated on the host and mapped into the containers running daemons like dnsmasq or bird

ansible

Starts an Ansible playbook that uses device-specific task lists executing Ansible device modules

sh

Uses docker exec command to execute shell scripts mapped into containers[3]

cp_sh

Copies shell scripts into containers (using docker cp) or virtual machines (using netmiko implementation of scp) and executed within them with docker exec or netmiko.send_command().

ns

Uses ip netns exec to execute shell scripts on the host within the container namespace[4]

netmiko

Uses the netmiko library to send configuration commands over an SSH session. netlab install ansible automatically installs the netmiko library; you can also install it manually with pip3 install netmiko.

startup

Configuration files are merged into a partial startup configuration that is passed to the containerlab startup-config parameter. This experimental method works only for containers and won’t report device configuration errors.

netlab uses Ansible playbooks and device-specific task lists to deploy device configuration snippets onto most devices, with these notable exceptions:

Device

Provider

Default configuration deployment method

BIRD

clab

Daemon configuration files and bash scripts[5]

dnsmasq

clab

Daemon configuration files and bash scripts[6]

FRRouting

Junos cRPD

KinD

Linux

clab

host- or container-side scripts[9]

Sonic

clab

inherits FRRouting configuration methods

VPP

clab

bash scripts, node configuration files, and VPP CLI configuration files[10]

Several other devices can use configuration methods faster than Ansible playbooks. These configuration methods are not enabled by default; you have to set the netlab_config_mode device group variable[11] or node parameter to use them:

Notes:

  • When using the sh method on Arista cEOS containers, netlab converts the device configurations into FastCli scripts and executes them as Linux scripts within the cEOS container. This method works on EOS software releases that have the ‌platform tfa phy control-frame disabled interface configuration command (probably starting with EOS release 4.30)

  • The Cisco IOS XRd sh deployment method uses a custom bash script that calls the xrapply ZTP command to load and commit a configuration file. The custom script is used as the shebang interpreter for the configuration snippets. This deployment method does not work on XRd vRouter or XRv virtual machines packaged into vrnetlab containers.
