Creating an OpenStack Network

Depending on the starting point of your Memset OpenStack project, you may have opted for a 'Basic Network Topology' during the setup. If not, the following steps should help you create a fully functioning virtual network infrastructure.

Firstly, to create your virtual Tenant Network, locate the 'Create Network' button in your Networks Tab.

Choose a suitable name for your network and click 'next'.

Next, you need to choose your network address scheme.

Its usually best to start with a generic /24 network such as 

For more information on CIDR ranges, see this article.

This network address can overlap with any other virtual network in your project. If your network will require access to any other network, or the internet, it is a good idea to set your gateway IP to the first IP address in the CIDR range.  

The last options to configure are: 

  • DHCP lease ranges. This is a range of IP addresses that can be dynamically associated with your virtual machines. Leave blank to enable the full scope of this address range

  • DNS Servers : A list of DNS servers that will be delivered to your instance by the DHCP server

  • Host Routes : Advanced configuration that can be used to specify persistent host routes
