To install a DHCP Relay server, download the Abiquo appliance (OVA file) and load the appliance on a hypervisor with VLAN support, such as VMware ESXi or Red Hat KVM.
The server requires two network interfaces. One of the network interfaces will be connected to the service network and the other to the management network. The virtual machine specifications are approximately as follows.
| Description | Default configuration |
|---|---|
| Guest OS Type | Red Hat (64 bit) |
| CPU | 2 |
| RAM | 4096 MB |
| Network adapter | Intel PRO/1000 MT Server |
| Hard Disk Controller (SCSI) | LsiLogic |
| Virtual Disk Image | dhcp-relay_XX_vmware-diskX.vmdk.gz |
| Virtual Disk Image Capacity | 9.77 GB |
To configure the DHCP relay server, you will need to know the following parameters.
| Component | Example value | Notes |
|---|---|---|
| Dhcrelay server IP address | 192.168.1.2 | This should be an IP address on the management network with the Abiquo platform servers. |
| DHCP Server IP address | 192.168.1.1 | This should be an IP address on the management network with the Abiquo platform servers |
| Dhcrelay management network interface | eth0 | Connection to DHCP server on the management network |
| Dhcrelay service network interface | eth1 | Connection to VLANs, which is a trunk connection on the service network. |
| VLAN range | 2-200 | Server will manage these tags that will be allocated to the VLAN networks |
| Network for relay service interface | 10.0.0.0 | The DHCP Relay will listen to VLANs using VNICs with this IP range. Note that there must be one IP address for each VLAN but the IP address is only used by the DHCP Server to identify the VLAN. You can use any network address that ends in 0. |
So for this example, we would enter the following parameters:
Management Interface: eth0 Service Interface: eth1 DHCP Server IP: 192.168.1.1 Service Network: 10.0.0.0 VLAN Range: 2 - 200
