This page describes how to configure an external network as the default for an Abiquo enterprise with the UI and the API.
For an explanation of external networks, see
The sections below provide GUI and API workflows to create external networks as the default for an enterprise and links to the User's Guide and Developer's Guide for the external network functions to use.
Two users can perform the tasks in the workflow. Typically, a cloud administrator would perform the first group of tasks, and a cloud administrator or an enterprise administrator could perform the second group of tasks.
GUI workflow for creating default external networks
This section describes a basic GUI workflow for creating default external networks. This section is designed to give an introductory outline of the process.
Create a new enterprise, assigning it to a datacenter
When you create an enterprise in Abiquo, you must give it access to a datacenter.
If you are creating the enterprise in the API, remember that you must add an enterprise-datacenter limit for each datacenter your enterprise will access.
When you set the default network for this enterprise, it will only apply to VMs that are created after the default network is set.
Allow the new enterprise to access the datacenter.
Â
See Manage enterprises in the section Allow enterprise users to deploy VMs.
Create the external network in each physical datacenter
Go to Infrastructure View, open your datacenter and click the Network tab. Click on the External page and click the + add button to add a new network.
It is important to check the VLAN tag availability in the datacenter where this tag will be used. If you share the VLAN tag across more than one network, the check indicator will be yellow. If it is reserved in Abiquo, the check indicator will be red.
Enter the network details and select the new enterprise that will use the external network, then click Save. Remember that this VLAN tag should not be available to the Rack for creating private networks, which means it should be excluded when you edit the Rack.
Create IP addresses and click Accept.
Next click the Available IPs link and make unavailable any of the IP addresses that you wish to use for administrative purposes, for example, the gateway address.Â

For each physical datacenter enabled for the enterprise configure a default external network
When to change the default network
You can change the default network at any time, but the new default network will only be applied to new VMs created after you change it.
Edit the enterprise, then edit the Allowed datacenter, and go to the Default network tab. Select the external network.
See Configure an enterprise in a cloud location in the section "Set the default network".
Create a virtual datacenter
The new virtual datacenter will get the default settings but these can be modified if required.
Set the default network for new virtual appliances
The new default network will only be assigned to VMs that you create after you change the default network.
See Manage virtual datacenters
API workflow for creating default external networks
This section describes a basic API workflow for creating default external networks. This section is designed to give an introductory outline of the process.
Check VLAN tag availability
The first step in creating a new external network is to check the VLAN tag availability in the datacenter where it will be used.
Create the external network in each physical datacenter
Supply an external network data entity. This requires an enterprise
Create a new enterprise, assigning it to specific datacenter
This example assumes that your enterprise was not created yet. It is also possible to use an existing enterprise, but when you set the default network for this enterprise, it will only apply to VMs that are created after the default network is set.

For each physical datacenter enabled for the enterprise configure a default external network
Create a virtual datacenter
The new virtual datacenter will get the default settings but these can be modified if required.

Create IP addresses on the external network
You can create a single IP address or multiple IP addresses.
