Managing networks using OpenStack Horizon

Create a network

To create a network from OpenStack Horizon

  • Under Project, click Network and then Networks in the sidebar menu.

  • Click Create Network in the right upper corner.

  • Name your network.

  • Check the Enable admin state box.

  • If you want to create a subnet, you could do that from this view as well, if so leave the Create subnet checkbox checked, if you prefer to follow our documentation and do this separately, you can clear the checkbox.

  • Under Availability zone (hints), select the availability zone that router or instance that you want to connect the network to, resides.

  • Under MTU, enter the value 1450. See MTU for more information.

  • Press Create. If you’ve opted to create a subnet at once, this option will instead be Next.

Note

In order to connect an instance or router to the network, you will also need to create a subnet which you can then attach to an interface on a router or an instance.
