Supported Platforms

The following virtual network devices are supported by config-generate:

Virtual network device netsim device type
Arista vEOS eos
Arrcus ArcOS arcos
Cisco IOSv iosv
Cisco CRS 1000v csr
Cisco Nexus 9300v nxos
Cumulus Linux cumulus
FRR 7.5.0 frr
Juniper vSRX 3.0 vsrx

Notes:

  • netsim-tools support FRR containers with containerlab. It seems that the FRR build tools changed the file system layout after release 7.5.0, crashing containerlab deployment process.

To specify the device type of a node in your virtual lab:

  • Specify device property in node data

nodes:
- name: c_ios
  device: iosv
- name: c_csr
  device: csr
  • Use defaults.device setting in lab topology

defaults:
  device: cumulus

nodes: [ s1, s2, s3 ]

Supported Virtualization Providers

config-generate script can generate configuration files for these virtualization providers:

You cannot use all supported network devices with all virtualization providers:

Virtual network device Vagrant
Libvirt
Vagrant
Virtualbox
Containerlab
Arista vEOS
Arrcus ArcOS
Cisco IOSv
Cisco CRS 1000v
Cisco Nexus 9300v
Cumulus Linux
FRR 7.5.0.
Juniper vSRX 3.0

Notes:

  • It’s possible to run Cisco IOSv/CSR or Juniper vSRX under Virtualbox if you build your own Vagrant boxes.

  • After building Vagrant boxes, edit devices section of topology-defaults.yml file to add Virtualbox support for individual network devices.

  • If you feel like building a downloadable Vagrant box for FRR, please send us the box name and we’ll add it to topology-defaults.yml file.
