Hi Danishka, Have you looked in the below link , I hope it clarifies to you. Try with flat/VLAN data network and using it with Openstack for understanding. https://wiki.openstack.org/wiki/StarlingX/Networking Regards, Yatindra Shashi IoTG DE From: open infra <openinfradn@gmail.com> Sent: 20 February 2021 20:36 To: starlingx-discuss@lists.starlingx.io Subject: [Starlingx-discuss] STX Data Networks Hi, I have a AIO simplex environment configured as per the starlingx r4 documentation. Under data network topology I noticed that controller-0 without any connections to available two networks. Is there documentation of how to create data networks of starlingx/openstack? To be honest, setting up the networking of starlingx and openstack is not clear.
