How do I deploy host configuration as a custom configuration template ?

[DanPartelly]

I have the topo below. The intent is to deploy "private vlans" on the bridge created for the multiaccess link . I need to deploy host configuration for this. I currently have a poor-mans bash script. Id like to deploy the needed host config automatically.

defaults.sources.extra: [ ../defaults.yml]
version: 2.0.0

name: isolation

defaults.attributes.link.isolated: bool

groups:
  external:
    members: [r1, r2, r3, r4]

nodes: [r1, r2, r3, r4 ]


links:
- group: nbma
  members:
   - r1:
     r2:
       isolated: True
     r3:
       isolated: True
     r4:
       isolated: True

Didn't seen any way to deploy on the Linux host on that page. This configuration has to be applied on the Linux host system itself ( the one running netlab ), not on any node in the lab topology. It has to configure a part of the underlay scaffolding of veths and bridges created on the host (But still needs topology access for bridge node name / ifnames).

Perhapes the only way is custom Ansible

sorry by host I thought you were meaning the hosts of the topology

My fault, Stefano. Should have been more explicit in my original question.

We don't have anything along these lines yet. I was thinking about making the defaults.providers.provider.start (and stop) into a list of commands, but never got it done.

At the moment, you can replace that command with your own script in which you'd execute the original command and get other stuff done.

As for "private VLANs", why don't you use a bridge node (for example, a Linux bridge in a container). It would be trivial to add configuration to that node.
