Hi@akhtar,

There are different types of NetworkManager available in OpenStack. Let's discuss one by one.

  • Flat Network Manager- This places all VMs on a single system using the same subnet and the bridge from made by the administrator. In this way, all VMs share a similar network that can be interconnected and are known to have Flat Network Manager.

  • Flat DHCP Network Manager- Much like the above aside from that the IP delivers to VM are assigned through DHCP (Dynamic Host Configuration Protocol).

  • VLAN- Unlike the single system idea, VLAN encourages more secure and separate system to VMs. It has a physical change to offer different virtual network and distinct IP range and extension for each tenant. This is to be sure most ideal decision for multi-inhabitant/venture condition.

Thank You
