Admin Guide 1. Abiquo: Auto. 1 DHCP Relay

 

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.

DescriptionDefault Configuration
Guest OS TypeRed Hat (64 bit)
CPU2
RAM4096 MB
Network adapterIntel PRO/1000 MT Server
Hard Disk Controller (SCSI)LsiLogic
Virtual Disk Imagedhcp-relay_XX_vmware-diskX.vmdk.gz
Virtual Disk Image Capacity9.77 GB

 

To configure the DHCP relay server, you will need to know the following parameters.

ComponentExample valueNotes
Dhcrelay server IP address192.168.1.2This should be an IP address on the management network with the Abiquo platform servers.
DHCP Server IP address192.168.1.1This should be an IP address on the management network with the Abiquo platform servers
Dhcrelay management network interfaceeth0Connection to DHCP server on the management network
Dhcrelay service network interfaceeth1Connection to VLANs, which is a trunk connection on the service network.
VLAN range2-200Server will manage these tags that will be allocated to the VLAN networks
Network for relay service interface10.0.0.0The 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
