For Abiquo private, external and public networks, the  the platform can manage their corresponding VLANs with an ISC DHCP server. Abiquo  Abiquo recommends one DHCP server per physical datacenter. Add the DHCP service to Abiquo when creating or editing a datacenter. You can use the Remote the Remote Services DHCP server supplied with Abiquo or another compatible server. If  If you have many virtual networks, you might need a separate relay server to manage VLANs for the DHCP server. For  For unmanaged networks, you do not need to configure a DHCP server and you must provide the network addresses to the virtual machines outside of Abiquo.

How Abiquo uses DHCP

Abiquo standard VLAN managements management has the following features:

• Virtual networks as separate VLANs
• The Cloud Administrator defines VLAN tag pools in Abiquo when creating the racks
• External and public networks are created in the infrastructure and define in Abiquo later
• Private networks will be defined by Abiquo from the racks VLAN tag pools

The connections in DHCP are as follows:

1. When you deploy a virtual machine, Abiquo (Remotes Services) supplies the network settings for the new VM to the DHCP Server.
2. When the new virtual machine powers on, it broadcasts a DHCP request for network configuration.
3. The hypervisor passes the DHCP request through a VLAN to the DHCP server.
4. The DHCP server broadcasts a lease with the network configuration for the virtual machine over the same VLAN
